sorry for my questions... but in my mind, the OP post is not clear ^^
"First you need to decide which version of the apk to download onto your phone. "... ok let's go !
"If you are using a 100% stock unrooted G2 you will choose the appropriate G2 Stock version." Well... i'm on 4.4.2 (KK).. but i'm rooted !! So which version ?!!!
"If you are currently using a rom that has the advanced driver (ask in your rom's thread, not here) you will choose the appropriate G2 Advanced version." Hmm... i'm on stock.
"If you are rooted, are running KitKat and ONLY and wish to add the 4kUHD video mode you can flash (via twrp) a modified media_profiles.xml file and install the G2 UHD KitKat version." Yes i'm rooted and running KK... but i don't want 4kUHD video mode..
So, to resume, i'm on stock 4.4.2, rooted and recovery. And i would test Xcam... but i don't if i must install :
XCam LG - for G2 Stock KK
XCam LG - for G2 Advanced KK
XCam LG - for G2 Stock KK then XCam LG - for G2 Advanced KK
Because it seems that advanced drivers have more options.. but i don't if it include in Stock drivers version... ;s
Thx a lot for your help
