Whenever I don't use my Coby for a day and a half, when I use it it makes a weird noise when I touch the screen regardless of the volume level. When I turn off then on, then its fine. How to fix?
I had a problem with an unreliable microSD card in my MID1126 that caused a 'crack' when I first tried to access an apk after bootup, followed by a system lockup. The tablet would also hangup during boot. Replaced the microSD card with a new reliable card and the problem went away.
