I don't know about other Fitbit devices but I bought 4 Charge 3 devices in April 2019, and three have different problems with the screen. The screen of the first one went completely dark although it was still syncing with the app on my phone. I called support and was offered to give me a replacement or 50% to buy another device (except Charge 4).
The second one first started with a small white line going across the screen, then three or four more lines, and then a bunch of them showed up to the point that it was impossible to read the text on the screen. I called support and got the same offer.
The third one has the brightness issue as described by others in this post. Today, I called support and was disappointed when I was offered a 40% off to buy a Versa Lite Mulberry and nothing else. Is Fitbit just shoving its least wanted/unwanted device to me as a compensation for my troubles? Not only it is exactly one model, a Versa Lite, but also in Mulberry color. I can't speak for other men but I certainly do not want to wear a vibrantly cute mulberry watch even if it was Rolex.
