I agree with you, if your phone has the same amount of ram as the galaxey 3 then it really does need more ram.
I had just gotten my galaxy 3, and when i got it i downloaded advanced task killer. It told me i had nearly 800-900 ram. Its been a few months now and i've only downloaded kik, fb, skype, a few games and whipser. my sd card is in with all my videos and pictures. Its now telling me i have less than 300 ram. it glitches and freezes. I can't even unlock the screen. I've cleaned it i've tried almost everything to get more ram but its not working. I have the task killer on every time the screen goes black and level aggressive. Tried everything and it litteraly has NO ram. So yes, many people must be getting this problem because ik it can't be just me. Its better than my nook but not as good as i hoped for it being my first phone along with only having it sense christmas. [B][/B]
