Hi guys.

I have installed Cyan on the Lumia 1020 RM-875 and I noticed a strange bug. Even if I set 'Battery Saver brightness' to ON in 'display', the brightness doesn't dim and the navigation buttons stay lit when the battery saver comes on, regardless of the exact setting (When battery is low, Now until next charge, Always). All the apps are up to date, and I've tried both soft and hard resets.

The brightness doesn't dim either on my 630. I've already ended up performing a soft reset due to various other circumstances, though.

My workaround at the moment is to manually adjust the display brightness settings at settings>display, assuming you're on Cyan.
Feel free to hard reset, as I haven't tried that yet.

The 630 doesn't have an ambient light sensor, so is unable to alter the brightness automatically.

I'm not talking about automatic brightness adjustment, which works fine. I mean the 'Battery Saver brightness' option in the 'display' app, which dims the display regardless of the brightness setting selected and turns off the backlight of the touch buttons, even in the dark. Strangely, it seems to work after hard reset for a while. I updated Battery Saver first, all worked fine. Then I updated the display app, the feature still seemed to work. However, after I finished downloading all the other apps, it stopped working again. I even tried deleting the display app by setting the date forward and reinstalled it, that didn't help either. Has anyone else encountered this bug?

I've this problem too... So annoying. Does anybody have a solution?

Did you find where the problem is, brother?

[blkvzgo]

No solution yet. I'm guessing we need to wait for Microsoft to update 'display'.

That's what I was thinking about. Screen saver disrupts everytime after Display update. I wish we had a solution. There is no difference between battery saver on and off...

Same problem here, battery saver brightness just doesn't work. But it did when I was on dev preview & black, rolled back to 8.0 & now on cyan. And seems those keys are on all the time too. Before if watching a video they would dim after a while.

Did a hard reset & reinstalled backup, seems to be working fine now. ❔❓

I also tried doing a hard reset, but didn't restore from the backup, I just reinstalled all the apps manually. It seemed to work at first, but then stopped working again. What phone are you on?

[Darren Kent 79]

Lumia 920. Still working fine 24 hours later.

lumia 920 8.1+cyan : same issue

[blkvzgo]

Flashed to a different firmware version (GB, was France previously). Firmware is Cyan, so didn't need any updates. The problem still persists, the screen brightness and button illumination are unaffected by battery saver.

[Evangelos Simopoulos]

Lumia 920 8.1 Cyan here. Austrian version, just updated. Exact same issue. Both before and after, soft and hard reset.

[gizzzmo]

The same issue here with Lumia 925 RM-892, WP 8.1 with Cyan...

[volpenger]

Does the last update fixed the issue ?
Not for me...

The update released on Oct 2 hasn't fixed the issue for me, either. It probably contained some optimizations for the newer phones.

[Divjot Singh]

I have it too. Any fix?
L920 DP + Cyan

[RoboLoftie]

I also have this. Also of note is according to Battery Saver, if I set it to Always on, the expected battery life drops by 5 hours, to 1day 5 hours. Set it to come on when the battery is low, it goes back up to 1day 10 hours. Something tells me Battery Saver isn't working properly.

Edit: L920 on Cyan.

Same issue, also on my Lumia 930 the Sunlight readability doesn't go off when going back to a room with normal light, the screen remains with the colours used for sunlight readability. It is hard to notice, but just use it, go outside in the sun, use the phone, go back in a room, the manually turn it off and you will see the colour difference.
It appears that the Display app and battery saver are not working properly.

Guys, could you please report this directly through the Microsoft Community to make sure they get the message?

Also, are you all signed to the Preview for Developers Program?

[blkvzgo]

Already reported. Personally I'm on the regular Cyan, not the Preview.

[BiggishTuba558]

I have the same problem on my 830 (firmware: Lumia Denim). I activated Battery Saver and Battery Saver brightness in Display settings. The Sunlight readability and the automatic adjustment of brightness are also active. When the smartphone is under the direct sunlight, the brightness becomes very high, while on my old 820 with these three options active, the brightness was always low and it was so much better.
I have not the Developer Preview.

[volpenger]

Now i have the same issue in 1020, also....
