[Galaxy Tab 8.9 Android Development] L3R0N:
The p4 ramdisk kept things going stable for a few days but then it went back to square 1 with the screen not turning on when it goes off unless its rebooted. So our issue still remains. I'm currently using the p4 lollipop ramdisk packaged with a KitKat zImage and things are very stable and seem smooth enough not as smooth as the figue kernel or decatf's but it works ok. I haven't had a reboot yet and the screen turns off and turns back on just fine. Mobile network is fine as well but mobile data refuses to work. I've been trying to find out the cause but I haven't had much time to do that. If anyone here is interested in using the kernel that I use ie p4 lollipop ramdisk+Kitkat zImage I am willing to post it here. Maybe someone else can figure out how to fix mobile data. Also I don't have any battery related issues either. I'm going to test v16 and see how it goes. I have exams so I'm not here as I used to be back when i didn't.
