    I understand that for the scanner to work you need to put it in full brightness. But since it's AMOLED I wondered if the clock part of the screen could stay dimmed. I think this would make the user experience of the scanner at night much better.
    Thanks for listening

    you shouldn't need to put the bright to full to use the fingerprint scanner an bright will do.

    Actually because the optical scanner requires light to capture an image of your fingerprint, full brightness is required. However, you don't have to manually do that. Once you place your finger over the sensor, the phone automatically lights up at full brightness to identify the fingerprint. I could've sworn it was only at the location of the fingerprint sensor, though, not the whole screen. Let me test it out really quick.

    EDIT: I guess it does light up the whole screen. Huh. Interesting.

    You should have a look at the (too) many threads on this subject.
    The optical FPR tech requires the extra brightness for reading accuracy. Some people are hoping that the process can be changed to only light the FPR touch area to full brightness rather than the entire screen.

    Mine goes full bright only at the location of the scanner. The rest of the display stays the same brightness.

    Might just be from locked then. I was just testing out from the ambient display mode to unlocked using the fingerprint sensor, and the clock lights up as well there.

    Try it with ambient display activated in Settings. I believe that you'll see the entire screen brighten. If you press the Power button first, then I don't think the whole screen brightens.

    Ambient display mode light-up is what's upsetting some folks. They want/use the ambient display feature, but complain about the light-up. Some of the threads are... amusing. ;)

    I kinda disabled it for that reason... mainly because with my device, I noticed that it took just a second longer for the fingerprint to scan my finger, whereas with the lockscreen, it's a tad faster at unlocking my device.

    Right, but that bit of 'tad faster' gets used up having to push the power button to bring up the lock screen, no? ;)

    I like the 'pick up to show' feature of ambient display. then the FPR is right there ready to read. And, I'm not a bit bothered by the whole screen lighting up for the instant it takes to unlock. If OP decides to modify it to only the FPR area, cool. But if not, fine by me, too. :D

    you must have the face unlock on.
    in low light areas the face unlock flashes the screen in order to pick bio up and subsequently open the phone.
    I find it too conflicting with fingerprint anyways so i turn it off.
    also it takes up additional battery as it runs Everytime you try to unlock regardless of fingerprint attempts or not .
