Sorry for the inconvenience! If your phone has a black screen due to accidental deletion of files, and the reboot is invalid, it is recommended that you try flashing or going to the after-sales service.

If you have strong hands-on ability and are willing to take the risk (failure to flash may lose the warranty), you can consider flashing the machine yourself. Lenovo asks the firmware area.

If you are not familiar with the flashing operation, it is recommended that you go to the local after-sales maintenance station to upgrade the flash. For specific tariffs, you can consult the staff of Lenovo authorized maintenance stations and service stations.

If the boot interface is still there to be saved (not the boot desktop)。。 If not there. Mourn.

The problem of the second contact of the mobile phone crash: This is the loosening of the contact of the mobile phone screen, which is not a big problem, but it can directly lead to the black screen of the mobile phone, which is difficult to find and can only be found after a lot of tests, which is generally caused by the mobile phone being bumped.

3. Mobile phone crash three battery problems: It is common for many mobile phones to have a black screen after using it for a long time, the main reason is that the effective use time of the mobile phone battery is 1 year, or it is three years but there is a problem in one year, and excessive use leads to the aging of the mobile phone's battery and insufficient voltage.

Your phone will have a black screen during a call, making it difficult to use the dialpad or hang up during a call**. In most cases, this is caused by the proximity sensor being occluded.

In response to this situation, there are several ways to avoid the troublesome situation. The first method is to cut off the film that covers the sensor and leak out the sensor, so that the black screen situation can be avoided once and for all.

The round hole of the light sensor is in the upper left corner! It will light up after a few seconds of moving, and the light sense is to let you play ** when you play, and the screen is turned off to save power.
