2.Phone Vibrator:

It works on the principle that an eccentric device generates vibration during rotational motion. In the event that the user does not want to make a sound, the mobile phone vibrator can remind the user when there are incoming calls, messages, and alarms without disturbing others.

It is recommended to do a factory reset to give it a try.

Reasons for the black screen of the phone:

1.Under normal circumstances, when the mobile phone stores too many things, many friends can feel that the mobile phone is running too slowly, and when their mobile phone is occupied by 80% of the memory that can be driven, it may crash.

2.This is the loosening of the contact of the mobile phone screen, which is not a big problem, but it can directly cause the black screen of the mobile phone, and it is difficult to find that it has to go through a lot of tests to find, which is generally caused by the mobile phone being bumped.

3.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.

4.There are a lot of applications for smartphones nowadays, but there are some software that are inherently conflicting, which can also lead to a black screen, so the black screen after installing a lot of software is basically this reason.

5.Many people are keen to flash the machine and use a better system, in fact, some system mobile phones are not very supportive, and some are not complete, resulting in a black screen when using it in the future.

It is recommended that you try the following methods to see if it can be turned on:

1.Press and hold the power button for 10 seconds to force restart the phone.

2.You can try charging for 20 minutes, then press and hold the power button for 10 seconds to see if it can turn on (the phone is completely out of power and recharged without any prompt).

3.When the phone is turned off, press and hold the volume up button and the power button for 3 to 4 seconds, and the phone appears emptyVivo phone logo, let go of the button to enter recovery mode, select wipe data factory reset first, select wipe cache partition after completing the waiting interface jump, and select reboot system now to restart the phone immediately after completion. (If you do this, you will lose all the data on your phone (except for the data on the SD card), including installed applications, **book, short messages, etc.) When there is a serious abnormality in the mobile phone and there is no other way to solve it, use this item with caution.

If the above methods still can't be turned on, it is recommended that you take your mobile phone to the local after-sales inspection and processing, and the after-sales technician will handle it for you.
