The alarm on my phone doesn't go off everytime. My "Ok" button sensor doesn't respond sometimes so I have to give it a few seconds before I try it again. And my screen goes black every once in awhile. If I slide it up and down 1x/2x, it usually comes back on. But all my issues are at random times so I can't even reproduce them. I've read that others have had problems with it freezing. Luckily I haven't had that problem yet. And my battery power is fine as well so I'm good there. Has anyone had the same issues I have? I upgraded to this phone in Sept. and have already switched it out once. I don't want to play the "switching phone" game. I did that with my previous Samsung phone and never remedied the problems. I've called customer service and they transferred me to tech support. They told me to upgrade my software so I tried that but I already have the latest software. And because my upgrade isn't up until May 2012, they can't give me a new phone with a new 2-yr contract. All I want is to get a different phone with another 2-yr contract. It's not like I'm asking for a free phone or something... Ugh! I'm really frustrated to say the least!!! The worst part is that my husband has the same phone so we're both stuck with issues!!! Ack~! Any suggestions/recommendatons?! Thanks.
