Poor graphics quality. I wonder where the 3Gb RAM was used. Tekken 6(PPSSPP) game is lagging. Even simple animations from "Criminal case" game is lagging. I’m so disappointed since this is the first time I tried Samsung phones and the performance of graphics doesnt meet its specification. Battery drains fast too. I charged phone everyday even if I doesnt play a lot of games(since I dislike the lagging effects). I hope Samsung will release an update/ upgrade that will solve this issues.
