[LG V20 ROMs, Kernels, Recoveries, & Other Developm] DevanWolf:
I had to mention another thing is that there is a bug where after a while (when I receive a Discord GCM notification) during charging with screen off, Android System crashes (resulting in having to unlock the phone again by PIN with unsaved work lost). Can be worked around with partial wake lock or BleKip. Pretty sure it didn't happen on joan.
