Okay, so I have been having this issue for close to 2 months now, and I finally have enough time to play with.
I am a big fan of phosh DE, but I have been having this issue where, since March, I have had a problem where after start up I get a black screen, backlight on, that persists even through pushing the power button (sleep). Pushing the power button just cycles the backlight on and off, but the black screen remains. (though it did help me find a dead pixel). The only way to get it to stop has been to hard shutdown the phone and restart. This however, just restarts the cycle. It shows be the PmOS splash screen, flashes me the desktop menu and then shortly afterward, (usually before I can access the menu and turn on wifi) it does the black screen again.
So I have been doing random updates to new images since, only every few weeks due to class, with no change. I finally got done with the semester and have actually started messing with it again, and nothing has changed.
I have now tried building from pmbootstrap and using an image, they both do it. I have used USB network to get the wifi started and updated, it didn't solve the issue. Finally, I noticed that it seemed like the camera made a whole lot of noise shortly before the death, so I tried hardware kill-switching the cameras to see if that helped. It seemed to have worked for a bit, I could get into the menu and open settings, and even get into the terminal before it froze up and died. It also seemed to always be after I changed the brightness (not too low, just touching it), but it still happened, just later, if I never touched it.
Now it is still happening as soon as I touch the screen with the newest pmbootstrap build even with the switches flipped. The closest I ever got was with the pmbootstrap build and the switches flipped and I used usb network ssh to turn on wifi and seemed to have everything working until the update, and it started again.
I have also tried phosh with pureOS and it does the same thing, (they called it the black screen of death) and they told me it could be fixed with hitting the vol+ and vol- 3 times each in under 5 sec. This did not work for their OS, nor for PmOS. So at this point, I'm really not sure what to do. Everything on the phone works fine with the terminal and ssh, but it wont let me use the screen with phosh.
Also, when this first started I tried PmOS with KDE plasma, and it worked fine. That was months ago and I haven't tried again since. I'm 90% sure it is something in phosh, but no one else seems to be having this issue. So, I'm not sure if it's something wrong with my hardware (would be weird since it doesn't break in other DEs) or something weird happening with me writing the images, even though I have done it a few different ways now...
Any help would be appreciated, cause I am really hoping to get to play with the phone some while I have this bit of free time. Thanks!
PS: If it's not obvious, I'm on a Braveheart.
PPS: Don't know if this is due to the voltage change to the screen, but it happened around the same time.
