Hello. I have a phone running graphene os, and recently the screen shattered. I am claiming a warranty on it, and will have to send the phone back. Is there any way, (I know the passcode) that I can recover my contacts off of it without the screen (maybe hooking it up to a computer so I can see what I'm touching?) Thanks.

I cannot see anything on the screen other than a green line. If this is not possible, can someone please tell me what is the process of wiping your phone with button (power+volumeup) combos? Thank you.

I believe they will wipe the device to do the screen calibration ( it doesn't need to be wiped but they will)
