These are 7 great capabilities of smartphones that are not known to many users but they are really cool, let’s understand together.

1. Infrared ray detection

While our eyes cannot see infrared, digital cameras do. In fact, smartphone cameras are sensitive to infrared radiation. When you press a button on the TV’s remote control, the infrared emitted by the remote will cause white or purple light to appear in the Camera app’s viewfinder. You can use this trick to check if the TV remote’s not working is due to a damaged battery.

2. Use NFC to read the information on the passport.

Currently, many countries have issued passports with RFID chips. This chip stores data about the passport holder, including a photo or fingerprint. One can use an app on an NFC-enabled phone to read this data.

3. Earn by earning Bitcoin

You can use your smartphone to earn Bitcoin virtual currency. However, you cannot become a billionaire overnight. In fact, you can earn a few cents a day mining with a high-end phone. That is why using a smart phone for this purpose is not a good idea, not to mention the fact that phone components will quickly heat up. However, it is interesting to know that a smartphone can also turn into a Bitcoin mining machine.

4. Support cancer treatment

A smartphone could be used in the fight against cancer and a number of other incurable diseases. Take the free Samsung Power Sleep app, for example. After installing Samsung Power Sleep, users can contribute the processing power of smartphones to the research process of scientists.

What you need to do is install Power Sleep, connect your phone to Wi-Fi. You can set a timer so that when you go to bed, the app connects your phone to the cancer research center’s servers. The server will “borrow” the processing power of the smartphone to increase the server’s ability to decode protein sequences (an important part of cancer research.’ This process will end after you wake up. .

5. Making a microscope

You just need to put a drop of clean water on the smartphone camera lens to turn it into a microscope. This drop of water will act as a lens, allowing the camera to focus from less than 2.5 cm away. The more firmly you hold the smartphone hand, the clearer the image.

However, be careful when doing so so that the phone does not get water inside. The photo below was taken with the camera of an LG G2 using manual focus and using a flashlight to illuminate the subject.

6. Measure distance

Distance measurement applications on smartphones cannot measure accurately with specialized measuring devices, but enough to give approximate measurements. To measure the distance to an object, simply enter the height of the smartphone to the ground, and point the crosshairs in the center of the object.

7. Measure altitude and air pressure

Speaking of measurements, a smartphone can use GPS technology to provide altitude data. Newer smartphones are also integrated with barometers to measure barometric pressure, or measure height above sea level.

You already know how many of these 7 capabilities are on your device, if you don’t know all of them, after reading this article you will have a better understanding of your smart phone.
