Ive had my moment for about a month now and i absolutly loved it until last night. last night i had great signal as usual and i tried to send a text message but my entire phone was EXTREMLY laggy. to the point where i couldnt even lock the screen. i did not download any new apps//widgets. it was happening on and off last night and then my battery drained. it went from 100% to 5%. Then it had a little circle with 2 arrows on the notifications bar (syncing?) but i wasnt using gmail or syncing anything. After I got home i rebooted 2 times and the same thing kept happening. I then put it on the charger because my batter was dying. i attempted to use it again but i kept getting the 15 minute warning screen as if i didnt have the phone pluged in (this was happening ever 2 minutes). this morning everything was fine. i just want to know what caused this and how can i prevent this. it was really annoying because i couldnt use my phone at all. also if i do a reset, does that delete all my contacts? if so how can i back them up? please help!
