My galaxy y. 1 wk old. After 3 days since i bought it. It lags. So i factory reset it. Then i installed angry birds and fruit ninja. It lags and lags and lags! Im so disappointed to this phone. For me it sucks . A very simple game like angry birds and fruit ninja lags?! Wtf?! I have 8 applications and installed it to my sd card Any suggestion how to speed up my phone?
