My Charge 3 is not working properly

[uniquelyc]

Starting 10/14/2020, my Active Minutes tracking has been inaccurately high. It seems like it's tracking around 10 active minutes every hour for most of my waking hours, even though I've been pretty sedentary working at a desk. Wednesday thru today my Active Minutes have been: 234, 122, 377 and 165.

I also only recently noticed that my Charge 3 stopped tracking my heart rate (or at least it has yet to sync with the app) on Wednesday thru Friday. Though today it had my heart rate around 100-160 for over 4 hours in the middle of the day which was not accurate at all.

I believe there's something wrong with the heart rate monitoring that's also causing the issue with the abnormally high and inaccurate Active Minutes.

Earlier in the week I was also experiencing the constant screen turning on and glitching between the normal wake screen and the DND/settings screen as well as vibrating each time it did this. I was able to successfully reset, but it continued a couple more days. I haven't been experiencing that issue coinciding with the heart rate and active minutes issues though.

Like a lot of other users, I'm also experiencing the dead pixels/horizontal lines on the screen. Mine are occurring in the top third of the screen. My Charge 3 also isn't vibrating/receiving notifications.

In general it seems like there's some kind of bug or glitch impacting Charge 3s in general. My firmware version is 28.20001.88.11 and my app is the most up to date version, release 10/13/2020 based on the Google app store. I've let the battery run out for now since I wasn't having luck with wearing it or attempting to reset.

Is there a planned update or something that will help with all of these issues?
