ADT panel extremely dim after factory reset

I factory restored the panel and when it came back it was extremely dim, I tried going into settings but that didn’t help, anyone else have this prob and find a solution?

You’re supposed to be able to tap “settings“ and then “screen“ to change the brightness. Did you not have a screen option? Or did changing it not make any difference?

Yeah I tried that, it’s like it’s stuck on the brightness setting when it’s only running on battery power.

That could well be true as a method of prolonging battery life. It’s only intended to run on battery as an emergency backup when the power is out. What happens if you have it plugged into the mains?
