Yeah, this phone is very tricky bastard.
I've tried various of kernels, but wifi doesn't work on 4.4.3 roms when I use them.
And about the gestures, in some roms they work, in some not, like for example now, on skydragon, I can only use double tap, every other gesture won't work, however I don't care about them because in using the magnetic cover, which is a very nice feature and the only reason I use flip cover like case.
