Causes and solutions of common faults of smart phones.

With the rapid update of electronic products and the rapid development of mobile phone industry, the popularity of Android smart phones is quite fast. In just a few years, smart time has basically replaced the traditional mobile phone, and people know little about the knowledge and skills of smart phones, so many friends will encounter many mobile phone failures and problems. Here I will introduce the causes and solutions of some common failures of smart phones.

1. The phone can't be opened.

Solution: After the newly bought mobile phone is upgraded or restored (including the first time that the SIM card is put into the new mobile phone), the mobile phone needs to be initialized for the first time, and the startup time is generally long, which may be mistaken for not being able to start the mobile phone. If the battery cannot be turned on due to excessive discharge, you can take out the battery and connect the mobile phone to the charger to see if it can be turned on. If you can turn it on and charge the battery for more than half an hour, you can turn it on normally. (This method is limited to the premise that the hardware of the mobile phone is not faulty.)

2. The mobile phone is put in the pocket, and the touch screen is in contact with the body, so that the incoming call cannot be answered by sliding.

Solution: Keep your hands and touch screen clean and dry, press the power button twice and let the touch screen recalibrate itself. After that, try restarting, which can usually be solved.

3. There are oil stains or water on the hands or the touch screen, which leads to the failure of the touch screen.

Solution: Dry the surface of the mobile phone with a dry cloth and press the lock button twice to make the touch screen automatically calibrate.

4. When using the charger to charge the mobile phone, especially when using the car charger, the screen touch of the mobile phone fails.

Solution: 1 Unplug the charger first, then press the power button twice, take out the battery and charge the mobile phone with the original charger.

5. Some software is installed on the mobile phone, which leads to the instability of the mobile phone system and leads to the automatic switching on and off of the mobile phone.

Solution: The most direct and effective way is to restore the phone settings or uninstall the software that is incompatible with the phone.

6. When the touch screen film is thick, the call will appear black screen or crash.

Solution: Remove the touch screen of the mobile phone and replace it with a standard new protective film.
