I've had some problems with my Verizon android Thunderbolt phone in the past, but now it's just beyond even turning on for some reason. It seemed to be a weird problem that sometimes the phone would freeze by itself and then reboot on its own. But a couple of days ago when it did this, it won't go any further than the LG logo because after the logo disappears it shows a solid black screen that's slightly lit up. It's not the charger because if I plug it into the charger, it can show that it's fully charged. If I take the battery out and wait a bit before putting it back in, it still does the same thing and won't go past the LG logo. Any ideas?
