My iPhone 4's mic has the strangest issue. It records just fine when recording any sort of video, but only picks up a droning buzz during Voice Memo recordings or phone calls (I can't answer the phone without the ear bud mic plugged in). Has anyone had this problem or know what could be up?

Why does my iPhone 4s shut down immediately when I play a big game?

When I play games like Gangstar Vegas, or Dead Trigger (but also with smaller games like offroad legends and beach buggy blitz), my iphone 4s suddenly shuts down 30 secs after I launched the game EVERY TIME. Tried restarting it, leaving it shut down for like a day, but nothing. This is the first time this is happening, I used to play these games for like an hour just fine, without lagging or shutting down. Now the only games I can play, are small games like Temple Run, Subway Surfers and Worms 2. I'm not jailbroken and on the iOS 6.1.3. I'm f*** desperate.
