I have a few questions about fixing phones:
# How to identify the problem (There is a special guide that explains all the symptoms that may happen on a mobile device and the solution?)
# How to open the device correctly
# How to correctly output and return a flat cable
# Is there an online guide that explains and shows all the components and components on the motherboard and plastics
# Is there a good guide that explains in general how to replace screen and glass with popular devices
# Where to buy spare parts for phones?
Bless you
