My Xiaomi Mi 2S hits the landlord and always has a black screen?

This is because Xiaomi phones have a proximity sensor on the top, and when you are talking and the top of the screen is blocked, the screen will go black. When there is no covering, it will be lit. This is to achieve the purpose of saving electricity. All high-end phones have this feature.

If your phone has a black screen when the proximity sensor is not obstructed when you are talking, it is recommended that you restart your phone and try to see if it is normal. Or check to see if your protective film is blocking the proximity sensor above.

Still can't work, it is recommended that you try the following operations in the normal state of your phone:

1. You calibrate the proximity sensor.

Enter * on the dial-up screen

2.Select the twelfth item "Proximity Sensor Test" in the hardware test that pops up

3.Click Start Calibration (Note: Do not obscure the proximity sensor during calibration).

4.The calibration passed, and it was successful! (You can dial and set the anti-false touch mode to test whether it is normal).

5. If the calibration fails, you can tear off the film on the right side of the MI character and try to recalibrate it.

6. Try to restore your backup to factory settings.

Back up data: Go to Security Center > Backup > Create Backup, and select all data for backup, which usually takes 3-5 minutes. Factory Reset:

Tap the phone menu key - System Settings - All Settings - Backup & Reset - Factory reset - Turn on Delete Apps, turn off Format SD card, and click Reset Phone below.

7. If you don't need this function of the proximity sensor, you can turn off and enable the proximity sensor in the call-menu key-settings-status setting when calling.

Thank you.

Black screen in use. Most of the black screen phenomenon is caused by their own third-party software, and the software that comes with the phone itself rarely appears in this situation. ** Third-party software, some of which have their own problems, some of which do not match the system of the mobile phone, and some of which are incompatible with the software.

Black screen in standby. Most of the straight phones have a power-saving circuit design, the phone will automatically turn off the screen if it can't detect the key trigger signal for a long time, that is, standby, when you need to use the phone, a button will activate the power-saving circuit, and then the screen lights up.

There are many commonly used software in the new mobile phone, and it is recommended that you do not install too much useless software. Although buying a smart phone is easy to use, some software that can't be used at all is also a waste of installation, which not only occupies memory, but also runs very slowly, and will also lead to a black screen.

There is no need to panic when there is a black screen, and there is no need to pick the battery immediately, leave the phone for about 3 minutes, and then press the button again to activate the screen. After many times of practice, it can generally return to normal immediately, so that it basically has no big impact on use.

The general red rice black screen,As long as you can enter fastboot, you can directly brush the line。 However, if you can't even fastboot you can't get in, it's more troublesome.

One is to read out a 100-to-M removable disk with an image folder in it, which can be repaired, and this is generally caused by the failure of the wire brush.

The other is a removable disk that is not left alone. But there is a Qualcomm port around com260, and this can also be fixed.

Hello. It is recommended that you try the following methods to see:

Click Settings - Applications - All - Find the software - Clear Data, clear the software data and then open it.

If all the software is slow to open or has problems opening, you can back up and empty the cache and user data in Recovery. Method: In the shutdown state, first press and hold the "Volume Up Button" and then the "Power Button", and let go when the boot screen appears to enter recovery.

Select Chinese Simplified >> Clear Data >> Clear Cache + Clear User Data. Tips: The recovery status search is temporarily invalid under the touch screen, use the "power button" to confirm, and the "volume button" to select.

If after the above methods, the corresponding programs are faulty, and other software programs are normal, you can judge that the program is not compatible with the system, you can try to change other versions of the program or game to try.
