This is not a common problem, but if your doppel buzzes continuously after charging, even after removing it from the charging base, please try the following:
- Remove doppel from the charging base.
- Make sure the charging base is plugged in and then place your doppel back in the charging base.
- Scan for your doppel using the app as normal - even if it's still spinning continuously whilst in the charging base and therefore does not buzz specifically to show that it's in pairing mode.
- Your app should find doppel so you'll then be able to turn it off via the app. Your doppel should then work as normal but we have found that trying to sync a new rhythm after connecting can help.
If these steps don't fix the problem, unfortunately, you should then wait for the battery to run out, this can take 3-4 days for the device to stop buzzing, and then start the charging process again. We have been working on a firmware fix which will solve this problem.
