Can try using some custom ROM, may solve your lagging problems.

i think your s3 got problem. genuine s3 or not?

i came from a s2, its noticeably faster than s1, and the s3 is noticeably faster than s2.
if your s3 is slower than s1, then something is very very wrong.

burned ?? so far don't have anybody facing it
only facing sdcard is corrupted

Anyone using/tried both wanamlite and slim bean? Currently on wanmalite v7.1 but doesn't really feel any faster compare to stock, wondering should I switch to slim bean...
It's a big hassle to switch different rom as you can't backup everything

If not mistaken, Slimbean is aosp, which dont have samsung apps/features like smart stay, sbeam etc. Wanamlite based on leak 4.2.2, so it still got.

And are you sure Wanamlite didnt faster than stock? anyway in sense of?

you may backup important things with titanium, no?

hope this could help. smile.gif

For some reason your phone must be doing media scan and forgot to stop.

Did you plug in USB otg to copy files?
How u unplug? Need go settings, storage then unmount
If u unmount using the unmount button in the notification tray, the media scanning bug will occur.

This is known bug for Samsung touch wiz rom. I read about it in s2 xda, but users says it affect note and s3 also.

anyone has this FB issue?
u chat in pc. and then once u go on9 on yr S3, Facebook message keep popping out non-stop. popping out messages you chat on pc when ur S3 is offline
