[Help] Nook HD touch screen constantly being touched

[Splader]

Hey guys, this is a weird error that just started for no reason that I can think of. I had the latest nightly build on my Nook HD when all of a sudden various parts of the screen would just be auto tapping. I tried restarting multiple times, I even went for a factory reset but ended up simply flashing TWRP on it and flashing the latest AOSP Rom.

The problem is, when I load over to TWRP, I'm still getting these touch errors. Does that mean that it's something hardware wise that was broken? Does anyone have any advice on what to do next?

All and any help is appreciated, thank you.

Try cleaning the screen thoroughly. It gets very sensitive when dirty.

Sometimes putting the nook to sleep and waking it up again with the power button is enough to fix "stuck touches", something gets reset when the screen is switched off.

Also, some 3rd party chargers can cause continuous random "ghost" taps all over the screen while the charger is plugged in, but the problem goes away as soon as the charger is unplugged.

One thing that can help you figure out what's going on is going into developer options and enabling the "show touches" option. That way you can at least see when a "ghost" or "stuck" touch happens. Be careful when entering passwords in this mode though, since it makes it easier for someone else to follow what you're tapping too.
