Iphone 4 jerky and lag during gameplay
Whenever I play a game like need for speed or any other racing games. I always get millionsecond lags when I play those games. It felt like my A4 chip has defects.
The whole experience feels very jerky, it's like the processor isn't strong enough to support the game.
I'm running on iOS 4.3.4. I tried hard reboot and restore without back up, and it didn't improve anything. The strange thing is if I put the phone into airplane mode or take out the sim card, suddenly everything begins to run so smoothly without any lags or jerkyness. I don't get why my iPhone is doing that.
Is it just me? Anyone out there has that same problem when they play games, please let me know. I would much appreciate to responses :)
iPhone 4, iOS 4.3.3
