Wyze Watch 44mm Firmware 0.3.90 Released - 6/2/21

Good morning, Forum Friends!

Wyze Watch 44mm firmware version 0.3.90 is releasing shortly! This has some experience improvements such as the screen lighting up when receiving a notification and improved connection stability as well as a bunch of bug fixes! :bug:

Read our Release Notes:


Hey, I’m in the beta program, and I got this update yesterday. It would be great if I could see what the updates are instead of waiting for the public release.

With this, it was only a 1-day difference, but with some updates, it’s a bit longer and I’m left wondering “well, what changed?”

If you want to know what is going on with beta you need to keep up with what’s going on in the beta section

did alarm get fixed ?

Hi there,
after 3.9 firmware update, [from 3.65] steps, heart rate, blood ox, text notifications, sleep recording do NOT show up on watch face only on phone. My wife sent the log files. Please let me know if there’s a way to fix this or revert to the prior firmware . Yes, we rebooted the watch several times after the update.

How about feature release updates to align better with the 47? If you released higher quality software from the start rather than using your install base for testing, perhaps your development team could refocus on features
