What about Red Mi note4 black screen? What about Red Mi note4 black screen cannot be turned on?

Solution:

First:

The important reasons for the failure to boot red rice note4 include the destruction of system files caused by application installation and the hibernation of the battery.

If the power is insufficient due to excessive use of the phone, and the phone is automatically shut down, no response or cannot enter the desktop again, you can be sure that the phone battery enters sleep due to excessive discharge. In this case, we need to remove the red mi note4 cell phone battery.

Then, the "universal charger" is used for charging, and the battery is forced to activate again to resume normal use. Make sure that the positive and negative connections of the battery are correct when using the universal charge.

After the charging is complete, install it on the red mi note4 phone and try to start the phone again to solve the problem.

Second:

Another reason why red mi note4 cannot enter the desktop is caused by improper software installation. We only need to restore the factory settings. When the mobile phone is completely shut down, press "power key" + "volume down key" and keep it for a while, the following screen appears, select "Recovery Mode" and enter.

(In Recovery mode, the volume key indicates "select", and the volume key indicates "OK ")

When the "green robot" interface appears, press the "power key" to enter.

Then, select the "wipe data/factory reset" item and press "volume down" to confirm.

After the factory settings are restored, select "Reboot System Now" to restart the mobile phone to enter the desktop.
