i have noticed that when i am playing with apps in the phone or sometimes in the morning after i havent used it all night, that is seems really slow to receive calls, and sometimes the systems slows down so much that i end up missing the call before i can select to answer. for example, ill be in the middle of a text, the text will become unresponsive then the screen turns to the ringing screen. i have it on ring and vib, but the vibe gets quite a few rings in before the ringer activates and then when i try to answer it it just wont answer until its too late and i missed my call. this has happend also when i wasnt doing anything today, it rang and then wouldnt let me answer the phone. i guess my questions are whether anyone else has had this problem, and if so is it a problem with the acclaim or with androids in general. this is my first android so i just wanted other feed back, and maybe a way to fix this if possible.
