Just had my cracked LCD replaced. Everything was working fine before the replacement but after that, a third of a centimeter and all the subkeys (Back, Home, Recent keys) we rented working. The tech tried to checkout the fitting but it still didn't work. Had to install an assistive key app to be able to use the phone. He told me to go back on Thursday to replace the LCD with a different one cuz this last unit they had might be defective. Could it be a screen seating problem or an issue related to glue remnants or excess adhesive?
