I just got my Nokia 770 about a week or two ago. Recently it has been closing applications when I didn't do anything to make it close. Also, it doesn't turn on sometimes, unless I plug it into my charger for less than a second, and then it turns on (even though it was on full power). I don't know if it is supposed to, but, it doesn't search for wifi signal when it is at 2 out of 4 bars of power.

I really can't figure out what's going wrong.


Thanks for any help
