Screen brightness on my charge 3

[SunsetRunner]

Had a charge 3 last year and it was replaced as it had lines on the screen. Great response and happy to get a replacement. But now that replaced watch is experiencing problems with the screen brightness. Sometimes I can c it and sometimes not. I have read the posts on here and looks like it’s not just me. I did the hard reset and was ok for about 12 hours ish. Now back to dim. It’s connecting fine to my phone and vibrating to say notifications etc. But I can’t c it xx

Done a hard re boot but still can’t c screen. It can’t even c what’s on the screen x

@SunsetRunner It's great to see that you've visited the Fitbit Community!

Let me help you with your Charge 3 screen not working as it should and thank you for restarting it. Since it is syncing try changing the clock face by following these instructions.

Let me know how it goes.

Don’t the clock change thing and seem to only last a short while then can’t c anything again??

I can not see anything on my screen outside ( in daylight) at all.

Same here.

My first charge 3 lasted just 10 months then went faulty and thus one is just over 12 months old and now playing up. What happens now? 
clearly a fault with something x
