Brand new 770 from woot. First time I turned it on, it took a few minutes to give me anything besides what now looks like WSOD screenshots I've seen... It finally got past that stage and functions fine, EXCEPT...

The screen tears and shifts. It's hard to explain so I have taken screenshots and attached them to this post.

Picture these anomalies as living, moving creatures. They're not static. They'll move left and right and sometimes disappear altogether. Sometimes they're minor...sometimes they make the entire display unreadable. I'm thinking perhaps this is a precursor to WSOD? I've sent an email to Nokia TS, but I thought I'd ask here as well. I'm sure it's a hardware issue of some sort.

Return the device and get a new one or money back. Don't accept a warranty repair.
