The fix is identical to the OG Pebble. Contact them first and they might replace it -- but you'll still have the same issue.
1. Turn off your OG Pebble
2. Remove the rear panel, either with the proper screwdriver or a small precision flathead
3. Gently lift up the panel and move it to the side. The vibration is glued to this panel, so go slowly. You do not have to remove the vibration piece.
4. Cut two small pieces of paper to fit the side of the pebble with the board exposed. Cut a space for the wiring, then slip it in.
I did that, and it worked for a while, but then the issues were back something like a month later. Adding more padding causes the back panel not to close properly so that's not an option. I'm stuck with the display getting weird every once in a while now(replacement is not an option, the watch is almost 4 years old at this point).
It took significant fighting (my original Pebble was 6 days out of warranty), but they replaced mine too, since it was doing some terrible screen tearing. I've purchase the Kickstarter Time 2, so hopefully it won't have the same issues (screen tearing is so prevalent for users of Pebble Classic, it's kind of amazing that it hasn't turned into a bigger issue).
agreed, nephew got his pebble steel replaced no questions for serious screen issues. I have minor screen issues occasionally though have had mine for a couple of years. Might try for a replacement. Might they send me a fitbit now instead..?
