Is you are using semaphore kernel, do not use ZRAM, one I set that, I have keep rebooting due to fall on opening launcher. Wipe data to solve the problem...
EDIT: no... i found it wrongly... the problem is
when i go to change auto brightness setting... i found my brightness set is -1 -1 -1 -1, so i go enable the auto brightness and go back edit set brightness, but i see it -1-1-1-1 again so i turn off my screen and turn on and KABOOM... bootloop...(this is my 3nd times)
searching a way fix and get no luck..(only wipe anything else data is useless) so i wipe data and reinstall+restore my apps again and again(lucky thanks to the NEW FUCTIONS, a remember choosing apps, GOD THX TO DJSound)...
now searching a correct way open auto brightness... It's really bad for me...auto brightness should be ALLOW for me!
