Guys I want ask, I bought an earphone.. The earphone when I plug in desktop or laptop it clear..
However when plug in my s2 when bass it sound like buzz ""spoiled sound /bunyi pecah "
Weird things I need increase my s2 volume to 60% only can hear normal loud and clear..
Any have same problem? My earphones is gshark brand..increase to 60% for music I feel kinda loud later I deaf lo

My first guess is that you didn't plug the earphone jack into your SGS2 fully. Did you plug in all the way?

Are you using any phone casing that is preventing you from plugging in the jack fully?

i nvr face the buzz sound unless the song quality itself is bad... haha my housemate also bought the rm59 philips brand IEM     IMHO our stock IEM is better than the rm59...
wat firmware u using?? i nvr used the leaked ver as i always wait another more stable rom to come out n i'll always prefer custom rom   i rarely faced FC while on custom or even in the stock rom when i start to use this fon... btw mine is non-g model.. try factory reset or uninstall the viber?? hope this may help.. ask sifu sifu here

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.
