After installing the JB build for my rooted tablet (Galaxy Tab 2 7" (WiFi) P3110 Gets Official Jelly Bean NOW! [get it here] - xda-developers) everything is working perfectly EXCEPT when I press the power off button or use the Screen Off icon (Screen Off app), the tablet shuts down, and a very long press on the power button is required to get it started again. :-[ Thoughts?
