I am having a small number of problems with lag on my Google nexus 7. After updated to android 4.2, it is probably causing extreme lag and keeps crashing for me, such as exiting an app, switching screen and etc, even sometimes just freezes. When I try to change the direction from landscape mode to horizontal, it runs slowly and takes about six seconds to rotate but just rotated within two second before. Is that a way to get it working normally?
