I received my C91 with ICS pre-installed. However, that version of Android does not currently support Flash and there are several sites I wanted to use that are based on Flash, so I downgraded to Android 2.3.4, using the official software from the Zenithink site. I read many of the threads here and followed criver's advice on dealing with the runaway android.process.media task that eats CPU. I also discovered a fix for the android.process.acore problem. (Basically for that one you need to look under "Accounts & sync" for a synchronisation that is stuck with the circular arrows permanently on. Then just turn off that sync and the task will stop clocking huge amounts of CPU). Everything on the tablet now works well apart from BBC iPlayer. When I try that, the sound plays fluently but the pictures are stuttering to the point of being unwatchable. I am able to play videos smoothly from other network sources, so I am confident that my wi-fi connection is not the cause of the problem. I can also play iPlayer content perfectly on other devices on my home network, so I know the problem is not between my wi-fi router and the iPlayer servers. That only leaves the tablet itself as the cause of the problem. I would be interested to hear from other UK C91 users. Has anyone managed to run iPlayer successfully and smoothly on the device? If so, did you have to do anything in particular to achieve that?
