Q1: Does it easy to install? Do I need other tools?
A4: Yes, very easy to install by following the installation video. This is a complete screen replacement iPhone 12 Pro Max repair kit, it came with LCD/Digitizer Glass and all the tools needed, you don't have to buy other tools separately.
Q2: Does it come with front camera and other accessories that are on the normal screen?
A2: NO, this iPhone 12 Pro Max LCD screen came with the back metal plate and camera holder, but DOESN'T INCLUDE the front camera, ear-speaker and sensors, you have to transfer them from your original screen.
Q3. How to do if the screen is blank/not lighting up/white line/flashing after installed?
A3: If the screen cannot turn on, that's because the iPhone 12 Pro Max LCD connector did not fully installed correctly or got loosen. When it happens, please reinstall the connectors and do a hard reset on your device.
Q4: Does 3D touch and Face ID still work after replacing the iPhone 12 Pro Max screen?
A4: Yes, the 3D touch works well like original. As the FACE ID, as long as you transfer the original camera and sensors on the new screen without damage the connector, it will work perfectly.
