Basically when playing games (all games), does anyone get random slowdowns? Like the game becomes super laggy for maybe 3-6 seconds?
Using System Monitor, I don't see anything happening with the CPU such as hitting 100% or anything like that, so it's doesnt seem to be the CPU working on anything else. As said, it happens randomly but will always happen if playing. This doesn't seem to to happen in any non-gaming apps or the homescreen.
Secondly, another random issue seems to be toggling WiFi on. Basically when turning on WiFi from the Notification Bar, it will just sit there and then eventually the phone will freeze. I can still press lock button (on the right of the phone) which will put the srceen off and on as if it was locking and it even makes the locking noise. However the screen will be completely unresponsive, completely unable to interact with the phone.
Again, this is random and doesn't seem to be brought on by anything I can see.
Holding the lock button to restart the phone still works.
Running completely stock. (GT9190) on stock firmware for South Africa. No root, nothing.
So guys, does this happen to anyone else? Hopefully this is normal and will be fixed by Samsung with 4.3/4.4 or something.
