Hi, I'm new to this website and just had a few questions about my Samsung Galaxy S3. I've had my S3 for about 3 and a half months now, and it feels as if my s3 has gotten a lot slower or laggier. For example, when I try raising the volume in the home screen, it takes a good 2 seconds before it raises. The same thing goes for when I press the menu button. However, this only occurs on my home screen with a flat picture, if it's a live wallpaper then the problem does not occur. Second, all of my games I play that are in constant motion have lag spikes. Such as in Jetpack Joyride, a simple game that did not even lag on my ipod touch 2nd gen, I would have a lag spike in the middle of playing causing me to die. Other than that, I have been really enjoying my phone! Model Number is SGH-T999 on 4.1.1(Jelly Bean). I've just been wondering if I should send it in to get checked, because my phone never lagged like this before the winter break started, and I've never dropped my phone yet. Oh yeah, and yes I have tried factory resetting my phone from settings, did not make a difference.
