[devanshsejwal]

SInce it is a android screen it has 5 pages so can u tell me the exact resolution so that i do not have to crop to make it the wallpaper ?
GTA 3 on google play store shows tht it is compatible with xperia u , nd i heard tht it doesnt work .. WHY ?

And plz tell me why this phone lags so much even with such a good hardware ..

Mali 400MP in S2 never lags and it has a dual core but still it is jerky while playing temple run.
Maybe because of RAM... so when we go to Manage App > Running Apps , please tell which one are not to be closed ( system files ) which are necessary fr normal thngs lik dislpay etc .... PLZ help it Lags.

And its a humble request to make the ICS update less RAM hungry
