My Nexus 5 is making a cracking/popping noise when I touch the screen in the bottom right corner and I get all kinds of colored lines across the screen. I attached some pictures I have and no, the phone was never dropped. The lines go away when I press on the screen but come back until I reboot. I am planning on contacting Google for a warranty issue through google play store but I have a few questions. I have CyanogenMod M8 installed on it along with TWRP recovery along with Titanium Backup Pro and a slew of other paid apps and customizations for rooted phones.
1) I've seen mixed answers regarding restoring the phone prior to RMA..will they take my phone back with it being flashed or should I revert it to factory?
2) If going back to factory condition, should I do that BEFORE I contact them and they call me back regarding the phone issues?
3) If I want the new phone setup exactly like my current phone is now, what would I do? Is it as easy as making a full backup with TWRP and moving it to my computer then when the new phone comes in, get TWRP setup again then recover from the backup?
Thanks for any help you can give.!
