I've had the Thunderbolt for less than a month. The screen routinely goes very dark with distorted colors, flickering, and color bleed. It's not a brightness setting, looks sort of like when a lamp goes out on a rear projection TV. Right out of the box the phone had the common problem of backlight bleed from the soft keys. It hasn't been wet or abused in anyway.
I've tried removing apps, no luck. Tried a factory reset, no luck. Sometimes it will go a few days with no problems but it always comes back. Today it's been mostly unusable, screen freaks out as soon as it comes up. I had the Eris previously and had no issues with it.
Does this sound like a hardware failure or is there something else I can try to fix it? I've searched various forums and can't find anyone else reporting this issue.
