I bought a Samsung U600 phone in December and everything was fine until recently. The signal is really bad! It doesn't matter where I am my signal is always about 2 bars 3 if i'm lucky. I can't send txs or ring people sometimes because of this. I always have to walk around trying to get a signal. Does anybody know a solution to this problem or is it just my phone.???

Also is anybody elses battery always low even when you have charged it for agesssssss.??
