Then we disassemble the phone. The disassembly process of Mate 20 is different from iPhone. The back cover needs to be removed first. The back cover of Mate 20 is glued to the middle frame. We need to heat the back cover for removal. Put the phone on the Heating Pad at 90 °C to heat for 2 minutes. Separate the back cover with a knife blade and pry piece. To facilitate separation, apply some alcohol. Please separate from left to right to avoid damaging the flex cable.
