回答“My LG G2 LCD screen is coming off after replacing it?”I had the same problem with mine. Is it that bottom right corner? You're going to have to disassemble the phone in order to get tape under there to stick properly. I would not attempt to adhere the phone without fully removing the screen. Your repairer should do this for you as this is a failure of their repair. How long has it been since you got it replaced? Was there no warranty on the replacement?
