I bought this phone off of craigslist and two days after I had it, before I could even buy a card to activate it, the touchscreen went all wiggy. Sometimes it works, sometimes it doesn't, and there's no rhyme or reason to it. It could work for hours and hours, but then suddenly stop working. Sometimes it works for about 5 minutes then stops. Sometimes it doesn't work at all. I've tried resetting it. I've tried power-down. I've tried pulling the battery. I've tried with the microsd card in and out. The results are always the same, it may or may not work.
