this is very odd and i dont know what i should do, right now all the physical buttons will not work except the menu and end call (red headset) buttons and who knows what else, since i originally had a combination lock with the 9 dots that you make a pattern with, it wont even come up anymore, i hit the menu button and the home screen just pops up. and i also notice that when i turn on my phone a satellite signal icon appears at the top bar where it shows the network and the internet connections. i dont know what is wrong with it. and im not even sure if its because when the battery died and i charged it with my car and instantly turned it back on and then i turned off my car while it is still urning on and hasnt finished, could it be the fact the phone shut off when it is checking the SD card? i really have no clue what to do now, someone please help me out on this.
