over the last 3 nights my phone has been utterly useless. when i try to call or text someone it takes about 1 or 2 minutes before either the call goes out or it allows me to text, however; there are other times that the phone doesn't even allow me to do this. it has also been shutting itself off & back on again for no reason (battery was fine). when i try to open any apps its the same as w/ phone calls or texts, only it takes even longer to open & also at times doesn't open at all. also issues w/ screen freezing, alarm not working, time not staying up to date, etc. overall its been a massive headache. but the weirdest thing is that during the day, it works fine???? so as a timeline, wed night the prob started, thurs during day phone was fine, same on friday & phone working fine now for the moment. it starts to act up around 7 or 8:00 at night. i use apex launcher & first thought that was the problem. i uninstalled it & just used phone w/o a launcher , but prob continued. i re-installed it cos that doesn't seem to be the problem. i've only had the phone since May, so i just don't get it. can. anyone out there help me out. last night i actually uttered the phrase, "this is driving me crazy, i'm just gonna get an i-phone!" obviously that puts my frustration level in perspective.
