I must say something for the rugged phone
As a niche branch of Smartphone, Rugged Phone has been misunderstood all the time. I hope my article can clear up some misunderstandings about Rugged Phone. Now I ask you a question, you can answer it silently in your heart, what do you think of when you mention Rugged Phone? How many people thought, isn't this just a cheap phone in a stupidly bulky case?
This is very wrong. First of all, the rugged phone is not as cheap as you think. Some rugged phones are even more expensive than many famous smartphones. For example, this phone, the AGM Glory Pro, is priced as high as $819.99. I'll admit that the rugged phone is a bit heavier than the average smartphone, and that has to do with its functionality and design, which can also have unexpected benefits.
I can tell you responsibly that the functions of the rugged phone far exceed that of the smart phone. The functions of ordinary smart phones can be provided by the rugged phone, but the functions of the rugged phone may not necessarily be provided by ordinary smart phones. Next, I will give an example to illustrate my point.
The most important feature of a rugged phone is waterproof, drop-proof, and dust-proof. If rugged phone can't do this, it can't be called rugged phone.
Many people will say that if it is for anti-fall, then I can buy a mobile phone protective case and tempered film to achieve this purpose, but the question is, what if the mobile phone falls into the water? What about the phone falling into the sand? Phone cases and tempered films may not protect your smartphone at all, and if you drop it in water or sand, it will cause irreversible damage to your phone. At present, many brands of rugged phones on the market have passed the IP68/IP69k test and MIL-STD-810H certification. If you don't know what these tests mean, you can read this article. Basically, you can understand that when you throw your phone into the water and pick it up, the phone can still be used normally.
In addition, the two most important functions of ordinary mobile phones are taking pictures and playing games. Today's rugged phone manufacturers know how important these two functions are to mobile phone users, so they attach great importance to the user experience of these two functions. Only by giving users the best experience can they be loved by users.
Next, let me give you an example, AGM H5 Pro has 4 cameras installed on the back of the phone, 48MP Main Camera, 2MP Macro Camera, 20MP Front Camera, in addition to 20MP Infrared Night Vision Camera, which can meet your different photo needs, Whether you want to take selfies, take long-range shots, take close-up shots, or even take clear photos at night, this rugged phone can also meet your needs.

There are still many users who like to play games, but they may encounter the problem of freezing, but this phone really won't let you encounter such problems, because the processor of this phone is MediaTek helio G85, no matter if you are an avid gamer or a demanding professional, you can rely on MediaTek helio G85 processor both while playing the newest games or multi-tasking through a busy day.
In addition, the rugged phone has many other powerful functions, which I will explain to you in other blog articles.

How to protect the privacy of mobile phones?
In the era of big data, personal privacy and mobile phone data leakage have become common phenomena. Although we have taken great care not to leave any personal information in public places, there are still businesses and software that we have not followed send harassing text messages. Perhaps we have been forced to get used to these behaviors subconsciously, and the thoughts in our minds gradually evolved from "Where did he get my mobile phone number?" But the privacy leak doesn't stop there. When you open various mobile apps, you will find that the relevant recommendation in the search box seems to be the content of the chat with someone just now. If you swipe down, the recommended advertisement turns out to be the product we just wanted to buy recently. Is Big Data Really That Accurate?
In fact, most of the reasons why our ideas have been explored so thoroughly are caused by mobile apps. When people use smart software for the first time, they will pop up some usage permissions. Under normal circumstances, in order to avoid trouble, we do not look at the privacy regulations of the app. After choosing to agree to all of them, some unscrupulous apps have the opportunity to view the personal information and usage data in the mobile phone at will, and then upload the server after a large amount of time. After data analysis, they can push content to us for some illegal profit-making activities.
Although many products on the market are now equipped with user-friendly functions, such as photo sharing and desensitization, screen projection information hiding, advertising tracking restrictions, etc., they are all based on the user's privacy rights and interests to ensure users' privacy and security as much as possible. experience.
However, in addition to the privacy protection of Internet products, as users, we cannot completely rely on operators, and we also need to take some measures to regulate privacy data. The author lists several protection measures below to make your privacy data more secure when you use your mobile phone. .
5 tips to teach you how to protect your mobile phone privacy
1. When browsing information on the APP or web page, limit advertising tracking, so that advertisers cannot push personalized advertisements to you, block continuous tracking of you, and all your characteristic data and browsing data will be deleted.
2. When sharing photos on the APP, selectively delete the photo shooting location, time, equipment and other information, and share wonderful, but do not share privacy;
3. When using the APP, if the microphone/camera/location provides the "authorization" and "permit only during use" functions, you can try to cancel the authorization and use the location function;
4. If you don't want to expose your call privacy, you can use VoIP. As the "new darling" of the telephone communication software, the Internet telephony software. The intelligent revealing and concealing function of VoIP effectively avoids the privacy leakage of the user's mobile phone number; it also has the function of encrypting the voice of the call. When this function is turned on, no one can check your call records, and you can also permanently delete your calls. Record, no one can find your call information.
5. Turn off the health data in your phone, because there are many apps that secretly steal your health and location data, so you can turn off or delete your real data regularly to avoid leakage.
AGM Mobile attaches great importance to the privacy of users, and we hope that the above information will be helpful to our dear users.

How to keep your phone battery healthy?
The frequent use of cell phones has made cell phone battery charging a common concern.
The batteries of electronic products have a service life, for example, the battery power of a new cell phone can last a whole day, but after two or three years, the battery life does not seem to be so durable. What's going on? How to charge properly to make the battery last longer?
Does the phone always have to be charged to 100%?
Some people keep their phones fully charged all the time, righteously maintaining enough power to feel safe. However, leaving the battery in a full or high charge state for a long time will accelerate the aging of the battery and make it less durable. Therefore, you should unplug the charger instantly after the phone is fully charged to avoid being in a high battery state for a long time in order to extend the battery life.
Some cell phone manufacturers have already taken into account that most people's habits are to charge their phones at night before going to bed. In order to alleviate battery aging, some phones are charged at night by first fast charging the phone to 80% power, then switching to trickle charging method for slow charging, and then charging the phone battery from 80% to 100% two hours before waking up according to each user's morning waking habits. This design allows for a more durable battery.
Note: When the power is close to 100%, the charging speed becomes very slow. People habitually call this stage trickle charging and regard this stage as the stage to protect the battery life.
Battery level below 20% before starting charging?
Generally speaking, let the phone keep at 30%-80% battery power can be more durable, when the power is below 20%, you need to charge the phone in time, but it is not necessary to wait until the power is less than 20% before you need to charge, lithium-ion batteries are suitable for multiple, small amount of charging, than a one-time fast full more to keep the battery in a healthy state for a long time, this charging method can also increase the cycle number of the battery.
When charging the phone first plug the phone or charger?
The correct step to charge your phone is to plug it into an electrical outlet first, and then plug the data cable into your phone.
Following the correct steps to charge your phone will not completely eliminate surges, but it will go a long way in avoiding the effects of excessive surges directly on your phone.
Unplug your phone first after charging. Because when unplugging the charger, it is easy to generate reverse transient current, which may also lead to a series of problems such as accelerated battery aging and shortened battery life.
Note: Surge, a transient overvoltage beyond the normal operating voltage, occurs in just a few millionths of a second of time in a transient and violent pulse.
How to maximize the life of the cell phone battery?
1, away from high temperature environment
Charging temperature as far as possible to maintain between 16 ℃ -22 ℃, when cell phones and other devices for a long time in the environment of more than 35 ℃, the battery may occur permanent damage, can no longer power the device for a long time, in a very cold environment when using the phone, although the phone battery use time will also be reduced, but this situation is only temporary. When the battery temperature returns to the normal range, its performance will also return to normal.
2, keep half of the power
If the electronic devices containing lithium-ion batteries are not used for a long time, the percentage of battery power before storage is also critical. When not using electronic devices for a long time, do not fully charged or fully discharged, the device charge should be kept at about 50%.

How do night vision cameras work in the dark?
Why we need night vision camera?
When our society develops to a certain level, people will naturally begin to explore unknown areas, and darkness has been the biggest obstacle on the road of human exploration since ancient times. Even with the invention of electric lights to disperse the darkness, however, in many places and occasions are not suitable or do not have the conditions to use lighting equipment, so instead of our "eyes" to observe the world in the dark - night vision camera was born.
In the highly developed modern city, there are many locations and occasions that need 24-hour monitoring are not able to provide overnight lighting, because doing so is not only a huge waste of resources, but also light pollution. In the remote wild world, many creatures start to move after nightfall, the light may seriously disrupt the biological clock of these animals. And at these times are necessary for the figure of the night vision camera, then, how does the night vision camera "night vision" it? Next I will introduce you to the principle behind the night vision camera.
The technical knowledge behind infrared light
At present, the night vision cameras we use are basically infrared night vision cameras, as the name implies, is the use of infrared technology to achieve "night vision" function of the camera. Before understanding the principle of infrared night vision cameras, we need to understand the technical knowledge of infrared light.
We all know that visible light is composed of red, orange, yellow, green, cyan, blue, and violet light with wavelengths ranging from long to short, and those with wavelengths greater than visible red light are collectively referred to as infrared light. Although we cannot observe the existence of infrared light with the naked eye, objects still reflect infrared light. Since there is no visible light or only weak visible light in a dark environment, objects cannot reflect or can only reflect a small amount of visible light to our retina, so we cannot or can only see a part of objects in a dark environment. The night vision camera can use the infrared transmitting device on the camera to emit infrared light waves. These light waves are reflected on the surrounding objects and are captured by the infrared receiving device of the night vision camera. This allows night vision cameras to discern the influence of people or objects around them without emitting visible light waves.
Components of the night vision camera
The main components of the night vision camera are also very simple. The most basic infrared camera is composed of the camera shell, the infrared lamp board, the camera lens, and the camera motherboard. The function and introduction of the infrared light board is to use electric energy to make the wick in the infrared light board emit infrared light waves and project them. The reflected infrared light is transmitted to the main board through the lens, and then the main board converts the optical signal into an electrical signal and finally converts it into a video signal for output. In this way, we can observe objects in the dark through night vision cameras.
The AGM Glory series rugged smartphones are equipped with a high-performance IR Night Vision Camera, it can capture black and white images with better greyscale presentation under complete darkness. 30 meters visibility, satisfying most night shooting scenario.

The most cold-resistant rugged phone, can be used as usual in -27 ℃ outdoor!
Waterproof, anti-drop, dustproof, rugged phones have been a long time, but now the large screen touch phone is prevalent, tough phones gradually fall into a niche, but it still has its own value of existence.
For specific groups of people, rugged phone is still essential. Delivery boys, engineers, field workers and even explorers, their living environment is always difficult to avoid high temperature, high humidity, high altitude, cold, wind, sand and mud, vibration and even rain soaked and other harsh conditions. This time ordinary cell phones may not be able to withstand, a rugged phone that can accompany them, is undoubtedly the best choice.
The new AGM Glory Pro, the first thing worth mentioning is that AGM is widely known for its waterproof, dustproof and dropproof skills, weighing 370g, it definitely stands up to the test in terms of protective materials. What's more, this generation of AGM Glory Pro does not stop there, it also challenges the natural enemy of electronic products - the cold.
Every winter, the ordinary phone is basically unable to be used outdoors. This is not only because of freezing hands, but also because the performance loss of lithium batteries in low temperatures will be greatly increased, so the phone will trigger protection in low temperatures, power down fast or directly black screen shutdown, can not be used.
To solve this problem, the AGM Glory Pro starts with both the battery itself and thermal protection. The battery itself also uses a more cold-resistant electrolyte and porous cathode material, solving the problem of lithium battery performance dropping dramatically at low temperatures; in addition, the phone enhances water insulation and designs the copper tube from SOC to battery internally, using the SOC as a heat source to provide thermal protection and reduce the impact of temperature on its performance.
Even in the bitter cold of -30°C, it is able to provide a long working time of 5.3 hours, while other phones will just quickly black out and shut down, leaving you paralyzed.
Although we cannot test the performance at -30°C, we can see the performance of AGM G1 Pro at 0°C with the help of refrigerator.
Even when placed in water and frozen into ice, the AGM Glory Pro still works properly. This proves its excellent water barrier capability on the one hand, and its low-temperature resistant design is really effective.
Remove the phone to see the temperature of the core components. Although the surface is immersed in ice and water mixture for a long time, the temperature reaches 0℃ or even lower, and it is a bit cold in the hand. But the battery still keeps working at 5°C, and the core temperature is kept at about 15°C, providing constant thermal protection for the battery.
The real technology can withstand the torture of the cold.

Smartphone terms decoded, MP, IR Lens, Macro Lens, what are they?
When we see some technical terms of cell phones or cameras, such as MP, IR Lens, etc., we may be confused as to what the meaning behind them is and how to define the good or bad of the products. Next in this article, I will explain in detail the meaning of these terms to help you understand and better select products.
1, What is MP?
MP stands for mega pixel. mega means one million and mega pixel means one million pixels. A "pixel" is the smallest unit of light sensitivity on a camera's light-sensitive device. Like the silver grains of photographic film in an optical camera, the light-sensitive spots on the "film" (memory card) of a digital camera are pixels.
To get a high resolution (i.e., fine photos), you must have a certain number of pixels. Of course, it is not the case that the larger the number of pixels, the clearer the photo will be, but the clarity of the photo is determined by the "dot image", not the number of pixels. The number of pixels is the sum of effective pixels, and the dot pixels are how many pixels per dot (inch, etc.).
2, what is IR?
IR lens is infrared lenses, mainly used for night vision, surveillance cameras. It uses a special optical glass material and the latest optical design methods to eliminate the visible and infrared light focal plane shift, so the light from the visible to infrared light area can be imaged in the same focal plane, so that the image can be clear. In addition, IR infrared lens also uses a special multi-layer coating technology to increase the transmission rate of infrared light, so the camera with IR lens is far more effective than the camera with an ordinary lens to monitor the distance at night.
Ordinary lens at night with infrared light, the focus position will change. IR lens focus in infrared light and visible light are consistent. It is also called the flush lens.
Because of the night use, the aperture should be larger than the ordinary lens. Aperture is called the relative aperture, expressed in F, indicating the effective diameter of the lens and the relationship between the focal length. The smaller the value, the better the effect.
3, what is Macro Camera?
Macro lens is a special lens used for macro photography, mainly for shooting very fine objects, such as flowers and insects, etc. Modern macro lenses are also good with new optical technology to compensate for a variety of aberrations from macro to infinity range of focal lengths, not only for shooting flowers and still life, and portraits, landscapes, etc., is a highly versatile lens.
Macro photography allows for close-up images of tiny or detailed objects, such as insects. Photographers use macro lenses when shooting close-ups because of their ability to focus at very short distances. Macro lenses are designed to allow for life-size images or better Macro photography has been used to capture certain details on objects and also to capture details that would not normally be seen without a magnifying lens.

How can smartphone with loudest speaker be helpful in our daily life?
Here, we need to understand a basic concept: decibel - the unit of sound pressure level (symbol: dB), for every doubling of sound pressure, the sound pressure level increases by 6 dB.
1 dB is the sound that the human ear can just hear; generally speaking, 15 dB or less we can consider it to belong to the " silent "; and 20 dB or less we consider it to be quiet.
20-40 dB is about the murmur of a couple's ear. Normal environmental noise intensity in 30-40dB, relatively quiet and comfortable; 40-60 dB belongs to our normal conversation sound, when more than 50dB (45dB at night) may affect sleep and rest, so that the normal physiological function is affected to a certain extent.
Above 60 dB is a noisy range, 70 dB we can consider it very noisy, interfering with normal conversation and communication, making people feel distracted and unfocused.
Above 90 dB (the upper limit of the national noise tolerance) will cause hearing damage and lead to other diseases, and stay in the space of 100-120 dB, if there is no accident, one minute humans will have to be temporarily deaf (deafening).
But there are cases where a high volume speaker is very necessary.
Do not forget that the above data is for normal people, for hearing problems in the population, such as the elderly, they have different needs. It is possible that what we generally consider as noisy sound is just right for them, so a smartphone with a good quality loud speaker can help them hear better.
For some people who work in a very noisy environment for a long time, such as construction workers, the surrounding environment may be more than 70 decibels, then if your phone volume does not reach this decibel or more, it is likely to cause you to not hear or hear clearly, so that you miss some important information or calls. Next, let's look at the results of a test done by GSMArena. Obviously, ordinary smartphones are not able to meet the needs of this group of people for the volume.
In addition, loudest speaker can have a broader use, for example, in the morning you have difficulty getting up, but you have to go to work, you have to go hunting, you have an appointment with friends to go out, especially in winter, wrapped in the blanket feeling really too cozy, ordinary alarm clock and can not wake you up, you begin to hesitate in the wake and continue to lie in bed, you begin to think about whether to change the plan, this time, At this time, if the ordinary alarm clock is replaced by a loud speaker, you will not hesitate to get up, as long as the sound is sounded, you are stimulated, you will quickly jump up from the bed to turn off the sound, this time your sleepiness is completely gone, maybe with the loud speaker, it will not become so difficult to get up.
In some extreme cases, smartphone with loudest speaker can even save your life, for example, you are trapped in a place, you need to shout for help, but your voice is too small, and only a few shouts, your throat is dumb, this time, with the power of the loud speaker, may be able to increase your chances of being rescued.
The smartphone with loud speaker is really practical, try to use the loud speaker phone to bring more surprises to your life.

Dumbphone or Smartphone?
Because of its function and appearance, people have always associated smartphones with young people and rugged phones with old people, but now more and more young people are choosing to use rugged phones.Why is that?I think the most important point is that we are dominated by all kinds of apps, smartphone can install all kinds of apps, but rugged phone only has the most basic functions such as making phone calls and sending text messages due to the limitation of technical conditions. This limits people's access to a wider online world to the greatest extent.I'm a 27 year old, I'm currently using an iphone 8, but I really want to change my phone, I want to try rugged phone, the next is my personal experience, maybe not universal, but somewhat representative.It's really rare for me to be able to spend a continuous hour doing something without being disturbed by other messages. When I'm working, I get messages from people on social media, and work groups often have message alerts, and even though they may not have anything to do with me at all, I still need to take the time to read them. Outside of work hours, my time is more fragmented. One minute I browse through the answers on Quora, one minute I chat with my friends on WhatsApp, one minute I browse on Facebook, one minute I browse shopping sites to see if there is anything I can buy, then I play games, then I browse Tinder to see if there are someone who has hooked up with me, and so on. I seem to be really busy, I have multiple apps to browse, but when I'm done, it's like I'm not browsing anything, but my time is passing while I'm switching between apps. The problem is, I don't get any information that helps me, I don't remember anything, and sometimes I even get some spam and I want to say what the fuck, I've been receiving information passively and I never have a choice about what I want to receive. Wait, I get it, all these seem to be social media apps.But I have to admit that there are some tool apps that are essential, personally, like Google Map, like Uber, like Airbnb, that really have made my travels easier.So to be precise, my life has become more convenient because of tool apps, but also more fragmented and meaningless because of various social media apps.So, at the moment I have two options, first, buy a smartphone, but only download some necessary tools, but as a human, I want to socialize, can I resist not downloading any social media apps? Instantly, I know that once I download this type of app, my time will definitely be divided. The other option is to buy a rugged phone, whether it's a social app or a tool app, I can't download it. I seem to be relearning how to live without my smartphone.

Understand thermal imaging technology and how does it work
Infrared thermal imaging technology is a passive, non-contact detection and identification technology, can use the target and the background or between the target parts of the temperature difference or radiation differences in the formation of infrared radiation characteristics of the image to find and identify the target, its two basic functions are temperature measurement and night vision.Thermal imaging camera works on the principle of thermal infrared imaging technology. Modern thermal imaging devices work in the mid-infrared region (wavelength 3 ~ 5um) or far-infrared region (wavelength 8 ~ 12um). By detecting the infrared radiation emitted by an object, the thermal imager produces a real-time image, thus providing a kind of thermal image of the scene. Its core is a thermal imaging camera, which is a sensor capable of detecting very small temperature differences, the temperature difference into a real-time video image display. But only see the thermal corridor of people and objects, can not see the real face of the object. Advantages 1, day and night can be used normally 2, extreme weather can be used 3, can see through the fog, rain, smoke and other obstacles 4, all heat-generating objects are nowhere to hide in nature as long as the object above absolute zero (-273 ℃), will be constantly outward radiation of infrared. Thermal imaging that is through the optical system, infrared detector chip and electronic processing system, the object surface infrared radiation into a visible image. Simply put, the principle of thermal imaging is to use temperature imaging to transform the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.Thermal imaging is not affected by visible light, can be 24 hours clear imaging, non-contact temperature measurement, through the smoke and fog and other advantages, can be applied to human temperature measurement, industrial temperature measurement, automatic driving, security fire, outdoor observation, etc.. Commonly speaking, thermal imaging camera is the invisible infrared energy emitted by the object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heat generation of the target can be studied to provide a basis for work and research. For example, the infrared thermal imaging camera can check the floor heating leakage, can accurately detect the indoor pipe network, such as the distribution and direction of the location of the floor heating pipes, water pipes, hot water pipes, and can accurately locate the location of pipe leakage. Underfloor heating leaks often exist in two phenomena.1. fuzzy diffusion of pipes at the leaky location, the storage of non-linear, presenting a cloud of heat in the infrared picture.2, the leak location temperature is high, in the infrared picture presents a white bright color.The main performance indicators of thermal imaging night vision device classification. 1. resolution: resolution is the assortment of thermal imaging night vision device is an important indicator, night vision device affects the cost of thermal imaging night vision device one of the keys. General thermal imaging night vision camera resolution of 160x120, 336x256 and 640x480 three. The selling price from tens of thousands to hundreds of thousands of dollars.2. the resolution of the built-in screen: we observe the target through the thermal imaging night vision device, in essence, is to observe its internal LCD screen. The top thermal imaging night vision device, its built-in screen resolution and clarity are very high, so that it is clearer observation effect and better vision.3. magnification: due to the technical bottleneck, the physical magnification of the thermal imaging night vision device, at present, the largest magnification can be produced for 5 times. 4. double tube or single tube: double tube in the use of comfort and observation effect are obviously far better than single tube, of course, the price of double tube thermal imaging night vision device will be much higher than the single tube thermal imaging night vision device, double tube thermal imaging night vision device in the production technology will be much higher than the single tube.
