I got my Maxx couple months ago right before they dropped the tiered data stuff.
Ever since day one I noticed that if my screen went black, when loading up apps (not when you put it to sleep), the backlight reveals a bunch of dark blotches, kinda like when you slam a calculator on the ground and see all those dark blotches...
I don't have any dead pixels or anything though.
Another thing I noticed lately, but it could be an app interference... Is that the vibration response when tapping on the screen or the soft keys is rather weaker than it was before, but it's not just that, but it will inconsistently go away for a few minutes and then come back... Which leads me to believe it's an app interference. But even after a few hours, it still keeps up.
Anyone know where the settings are, if there are any, on the stock ICS rom to mess with the haptic feedback?
