VivoX20' s mobile phone button is on, charging is unresponsive, and it can't be turned on. There is no electricity when the time is set in the card machine, but the screen is black and the message cannot be received. Solution:

First, connect the computer with a data cable and charge it for 30 minutes (it may go into hibernation due to the exhaustion of power and need to be activated).

Mobile phone hardware damage or system crash.

Hardware damage can only be solved by maintenance, and system crash can be solved by brushing the full version of the system package.

Press and hold the power button for about 10 second to start the machine.

Generally, the battery is too low. Just charge it for a while.

Or the cell phone is left for too long, causing the battery to sleep. In this case, the battery must be activated. To activate the battery, the charger with higher voltage is generally 6-9V. After plugging in the commercial power, align the output line of the charger with the negative electrode of the battery, and align the negative electrode of the output line with the positive electrode of the battery for instant contact. As long as there is a spark, it is OK.

Replace the battery and troubleshoot the battery.

If it still can't be turned on, it is recommended to send the mobile phone for after-sales inspection and maintenance.
