I have come across this a few times on the forum, though I would like more information about them.
I saw pieces of information here and there, also about incompatibilities with some firmware versions, I also found this topic.
Though it’s quite hazy for me, so could someone (re)explain to me
- which are the different types of screen, how many there are and how to recognize them
- which are the firmware incompatibilities with which firmware versions
- help me identify this screen and understand why it has this unconventional sticker on it (it has a number starting with A3):
I have observed that, when I use a FP2 with it (either FPOS Nougat, Pie Beta or LOS 17.1), when it goes to sleep, the screen brightness diminishes in a jerky way, and I thought it might be due to it being an old screen.
Thanks in advance!
