loose touch id/erratic after screen replacement
i just changed my broken iPhone screen using a third party screen and jkept the same home button everything work but the touched home button is slightly loose with i think is causing the touch id to be erratic as sometime it won't recognise my fingerprint and when i add a fingerprint it is really difficult as sometime it might say "cannot read this fingerprint" or "you moved your finger slightly" etc managed to do it with one finger but sometimes it will unlock the device other time it won't.
personally i think it is the gasket that hold the button in place it might be lacking adhesive but I'm not sure
anybody know how i can get it to sit firm again and if this will correct the problem
any help will be thoroughly appreciated!
