I got installed, Google Edition 1.5 debloated stock rom on 5.0.2 android trough TWRP, also I have flashed Snapdragon Camera.Honestly that Snapdragon Camera is excellent, pictures have extra quality, focusing is insane but needs some skills if using manual focusing and video recording is stabilised to maximum with also extra quality.
So, untill 6.0 android custom rom does not come out as 99% stable official, im sticking to this rom on 5.0.2.There are some 6.0 roms given as official, but I dont find them stable as they should be, those roms are about 95% finished, but 4-5% makes huge difference.
