Q: the display is abnormal, the touch is not working
A: In general, because the cables are not installed in good condition, you can re-install it. Key Points: if the cable interface is long, please align and buckle one of the ends first, then buckle the other end, Do Not buckle it directly from the middle! When installing the cables cover & close up the screen, should avoid moving or pulling, so as not to loosen or even damage the cables.
Q: striped, flickering
A: Due to a loose connection between the lcd screen and the logic board, in this case, just reconnect the cables. there is also a certain probability that the screen will generate static electricity. so there will be striped, flickering etc, normally it will be automatically eliminated after two hours.
Q: fingerprint, front camera problems
A: Restart the phone, if still has problem, reinstall the home button or camera cable.
Tips: If your screen cannot power on after install and you think the screen is defective, do a hard reset:
Hold down your iPhone's Power button and Home button together for at least 10 seconds until the logo appears. Tks.
