So recently, my phone has been acting really funky with false touchscreen inputs. It began when I had Simply Stunning 5.2 on it, so I wiped everything x3 and installed SS 5.4. The problem got worse, so I tried a froyo rom which also did not help.
Now I'm back to the stock 2.2.2 rom/kernel, and it has greatly reduced how much it occurs, but it still happens. It seems that whenever I try to do anything that makes the cpu have to work hard, then it triggers the false touches to begin again.
3rd party chargers seem to worsen the situation, though using the original charger doesn't necessarily fix it either.
Is this necessarily just a bad digitizer? The fact that the rate of incidence seems to be positively correlated with cpu usage, 3rd party charging, 3rd party kernels/roms makes me think that there may be something else going on...
