My Fitbit display is not working . It charges well and collecting data that I can see via app. How can I fix the touch screen display. I have Fitbit versa

Have you tried a hard reset? Google how to do it. If that doesn’t work then it’s possibly a screen connector loose on the board. Repaired one before that had that issue. If connection is ok a new screen can be bought from eBay. There simple enough to work on. Removing the screen can be fiddly but take your time using a sharp blade. Watch your fingers, I use a razor blade and isopropyl alcohol. Start at the side working round leaving the bottom until last as that’s where the ribbons are.
