My nexus 10 has hardly any apps on it because I only use it for some very specific tasks and I hope to just keep it stable. One of the apps I do use is DirecTV to watch live TV. The only problem is once I updated to the latest OS version, 4.2.2, I have video and audio stuttering. Is there any way way to revert back to 4.2.1. Am I now forced to root if I want a solution?
