Hi, I have been having problems with my unbranded 7 inch Android Jellybean tablet witha WM8850 chipset. It was running slowly so i went into developer options and enabled the show CPU usage option.
I can see that a program named yaffs-bg-1 is using a high percentage of my CPU load. I did a quick google search which reveals this is to do with the file system for nand flash drives. but the only other article i could find with someone having an issue with it was someone who was using XBMC (which i am not)
I have uninstalled nearly every app but it still using high cpu load. rebooting or even leaving the tablet idle doesn't seem to fix the issue.
