they deliberately complicate repairs so that they will be paid more. the staff is rude and does not go to the meeting. they charge a fee before the repair. It was necessary to replace the battery on the pixel 3. to do this, peel off the back cover, insert a new battery (I had my own new one) and glue it back. The "master" also wanted to peel off the display for this, while warning that they could damage it, but they are not going to be responsible for this (although technically this is simply incorrect, the display does not need to be disconnected, which can be seen in many videos on battery replacement for this phone model).
