I've got a few problems on my GS2. Using it for games, camera, messaging, browsing seems pretty fine although there's minor lag being a G version. But the music player is all f**ked up. Its pi$$ed me off because music player is one of the main reason I bought this phone. I tried every player known to android Poweramp, playerpro, winamp, stock player end up being the same outcome.
First problem is while playing some music it skipped some files. Sometimes the whole playlist. But if I pause it and using Fast Reboot apps then played again from the starting point of the skipping it still can play until the next skipping problem. While listening to mp3, I have to constantly worried when the skipping will occurred. There's two thing I suspect. Probably too many apps and games (but on idle mode I check the phone only used 4oo something from 1GB allocated RAM). Second is, the 32GB class 4 micro sd card. Anyone knows what caused this and the solution to this problem?
Another problem, also the music player. It happen when my phone been on for a while. Like the whole day at the office and at the end of the day when I want to go back and turn on the player to listen for music. Then when I put the phone in my pocket it freeze/hang. Can't do sh*t unless I take the battery out. It happen every single day and its freaking frustrated and embarrassed to my other coworker. Using a phone that almost cost 2k but hang everyday and need to take casing, battery cover and remove the battery. Its humiliating. My suspect is the proximity sensor. I wonder if I can disabled it somehow. Solution guys?
Sorry for the long rant. But to spend almost 2k for this GS2 but facing problems far more often than my RM300 Mi-300, you've bet I'm pretty pi$$ed off.
Flashing a custom rom on your G version might solve the problem As i've read on multiple threads
