When I plug the front camera proximity flex cable to the phone it takes ages to boot once it does its so slow I have no service battery health has a spinning circle wifi shows connected but cannot browse anything setting apps takes ages to open and when it does I cannot scroll what has happened as it was fine before I disassembled it when the flex for the front camera is unplugged the phone works fine is it damaged or is there something else going on?
replace the front flex it is a quicker option at trouble shooting
