Backlight won't stay on while on watch face

I set my backlight to "No timeout" on Watch Mode (also Keys off, Alerts off, Gesture off, and Brightness 5%, if that matters) because I like to control when to turn it on or off (hate timeouts).

Used to do exactly like this on my old Fenix3 and it worked flawlessly, but on 935 the backlight stays on only when navigating through the menus. If the watch is on watch face it will timeout in just about 8 seconds!

Is this a bug and should be reported to Garmin or is it a common behaviour in new Garmin watches (maybe to preserve battery life, but again, it should give me at least a couple of minutes, not just 8s)?

Hi guy,

I also face same problem. BTW, after update the firmware to 4.10. Problem solved!!!

Just wait the new update.

P.S. may you need to check FW update by your watch. Goto System -> Software Update. I do that and found the new update wait there.

Hi Tarosoft! Glad to know I'm not the only one that noticed this problem.

You said FW 4.10 solved that for you? Weird, I'm on 4.10 here too and the problem persists... I even chatted with a Garmin person and he could reproduce the wrong behaviour there. Guess they will request a bug fix (hope they will!).

Looks like there will be a fix in due course for the 935; you'll just have to wait for it to appear in a 935 software release. From the just published Fenix 5 4.21 beta release notes:

4.21 Change Log Notes:

Fixed an issue where the backlight would turn off (outside of an activity), even though the backlight setting was set to, ?No Timeout?.

Great news Crispin! Thank you for the heads up. ;)

Wow, surprise. Now I don't know how my problem solved!!! I test this issue immediately after finish FW update. I found it gone (FW v4.10). Also use my watch 2 times after. It's OK. The backlight stay with me until end of running.

You may like me, I always run at the twilight-night time, backlight very needed. :)
