Ok so I've searched what feels like a million places and finally am comming here as a last resort. I will try to be detailed in everything i have tried up to this point so sorry if this gets a little long. I hope this clears up problems on this phone for anyone else with similar issues.
So the problem is that i am experiencing major lag on this phone. Let me specify. Mostly during games, which some are unplayable. Now that being said, I have not tried many games but here are some specific ones that have had some problems:
Nova 3 (which I am unsure of compatibility due to mixed reviews), The lag makes the game unplayable, online and offline
Modern Combat 4 (lag isnt too bad but still makes the game hard to play and not fun),
Shadowgun Deadzone had a wierd blur effect which made it unplayable --- fix : I had tried chainfire which fixed it but also disabling hardware overlays fixed this issue --- this is just some background info maybe it helps maybe it doesnt.
I have even noticed some lag on vector, a non graphicaly intense 2d game.
Some lag occurs even on the home screen as well (mostly when the device is first turned on and the home pages have not been loaded into ram yet, but this still shouldn't happen).
I know this phone has a weaker graphics chip and processor than the international version, but with the adreno 225 and the snapdragon s4, this device should be able to play these games and not lag on the home screen.
specifics: power saving mode is not turned on, I have tried to disable hardware overlays and force gpu but neither did any good (execpt shadowgun listed above). I have tried rooting and installing chainfire, this didnt fix the lag. I am on stock android 4.1.1 right now (rooted).
This phone is nearly new, about 2 months old.
So I guess my next step would be to overclock? does anyone think this would help? My point was that this phone stock should not have these problems and maybe I just got a bum phone.
Ok so thats the main problem, another, I have recently experienced battery drain. With all radios off, the phone not used (in my pocket, turned off) I am experiencing about 8-10 % drain per hour. - I dont know if this is normal but if any suggestions please let me know. While in use (browsing internet) I get about 40 -50 % drain per hour.
Thanks again to anyone for reading or providing help. Any suggestions are appriciated.
