FAQ
1) What can I do to retain the Face ID of my phone?
1. Face ID only works with the original front camera and sensors assembly for user protection, you have to install the original iPhone 12 Pro Max digitizer screen components on our screen correctly.
2. If the Face ID doesn’t work after using the screen installation, please make sure all the parts are put in the correct places, and reset the Face ID on the setting then do a hard reset.
2) There are black/white dots or lines on the LCD iPhone 12 Pro Max touch screen, what should I do?
This may be caused during transportation, incorrect installation, or incorrect usage of the screen, please do not press too hard on the screen or drop it during installation or daily use.
3) Why does the touch function can't work properly after connecting all the cables?
The touch issue might be caused because the cables are not installed correctly. Please try to unplug all the connectors on the logic board. Then use dust wipes or cotton swabs to wipe all the sockets carefully and reinstall the screen. Make sure you connect all the connectors correctly with a "click" sound and make sure the metal plate over the connectors of the LCD digitizer for iPhone 12 Pro Max is screwed down properly.
