I tried to go back to TW this morning but i still have the same problem than before (the reason i switched) it happens on every rom. even stock. When i open an app, it often freeze for a non negligeable amount of time (most of the time more than 30 seconds) and it happens often.
I don't have this problem with AOSP rom...
I'm running 4.3 with 4.3 bootloader. tried sky-note, Jedi and stock 4.3 from rogers. (i know how to flash roms, i've got no problems before and i've been flashing Jedi roms since the beginning.)
When using aokp 4.4 i have absolutely no lag issue, it is as fast as my greyhound
however i need a working focus on my camera because i used to scan business cards with camscanner.
If anyone have ideas, i'm ready to try some stuff!
Thanks every one for the help
