Is it an AMOLED at least or does it have horrible viewing angle and backlight (lk2nd screen is more gray than black)?

Have you tried disabling suspend like described in https://wiki.postmarketos.org/wiki/Qualcomm_Snapdragon_410/412_(MSM8916)#Suspend? It's not very well tested at the moment and provides little benefits so far.

I can't seem to reproduce this with my trash screen.

I'm still undecided if we should make this change since it only seems to affect your device, and it does potentially increase power consumption a bit in some edge cases.

Let's keep it open for now I guess, it doesn't hurt and might make it easier for others to find the workaround we came up with.
