Okay, I thought there were other problems over time.
I noticed that my battery life increased significantly when I turned off the automatic brightness setting. It's winter, I spend a lot of time indoors, so I can set the minimum screen brightness all day long. In the summer, it won't work. By the way, it's very irritating that with automatic brightness in the middle of the night, the watch brightens to about 1/4 of the scale. I thought it had to learn or something. However, every time I manually moved it to the minimum, the watch would have 1/4 of the brightness setting again after unlocking it again.
It's a bit sad that despite all the settings on yours, it only lasts 7 days. Samsung said 13 days, and you have everything on low anyway. Samsung meant 13 days when it just displays the time on the simplest dial.
As for the measurements, sometimes the hair on your wrist prevents the measurement of blood oxygen. Other values may also be less accurate, but I have no way to check that.
As for sleep, I also have the whole night in tiny red bars informing me about waking up. It's annoying, because I didn't sleep with the Fit 3 for 44 minutes tonight, and I didn't wake up once.
I was afraid at first that the PPI would bother me. After unpacking the watch, it was pixelated, but after a week I think I got used to it.
As for the software, I have the latest available installed. That is, R390XXU0AXHD, with a size of 19.28 MB.
