Hi! First, I think I ought to give some info on my tablet - ZT-280 C91 xxx2nxxx model running rooted ICS. Did you ever think you C91 was a bit too slow for a tablet with a cortex a9 and 512 Ram? Were you ever uncapable of watching a video because it lagged horribly? Do many programs force close on your tablet? I had these problems, so I decided to find the problem and do something about it. So now that I've "solved" that problem I'd be happy to share my experience with you: I had this problem even while my tablet was with Gingerbread - so I guess some people may also have such a problem. 1)How to identify it: Install "Android System Info" and go to Tasks - there you should be able to see the total CPU load - if your CPU's permanently at around 100% and you have a process - "android.process.media" - that's also consuming a lot of cpu, then most probably the bad performance of your tablet comes from this. 2)Just killing android.process.media won't solve the problem - it will reappear once again. Apparently android.process.media has a lot to do with a certain application - "DRM Protected Content Storage" - if you kill it android.process.media will disappear for a short amount of time, but it will reappear later when DRM Protected Content Storage starts again... The best way, that I found to solve this problem is to write this in your terminal emulator: su pm disable com.android.providers.media If you have any questions please feel free to ask.
