It is not difficult to learn mobile phone maintenance. Just find the bad part and replace it with the good one. Handwork is also important. Just practice more at ordinary times.

The hard part is the circuit design of the mobile phone board.

Ganguan Mobile Phone Maintenance Training School starts with basic teaching until students can independently repair domestic phones, brand-name phones and smart phones.

Their address is: Floor 8, Aihua Building, Huaqiang North, Shenzhen. There is also corresponding information in my space.
