Toch flashlight and face unlock recognition

Hi!

I enabled face unlock recognition and noticed that during front camera watching me before recognition is done, I can not use flashlight (torch) on rear panel.

I have flashlight enabled in smart buttons settings (double tap to power button - enable/disable flashlight) and I surprised that after enabling face unlock recognition option I can not use flashlight via double tap to power button. In the dark (where flashlight is needed and by the way face recognition is not working) face recognition try to recognize me for very long time and flashlight can not be used during this procedure. Even if I bind flashlight to countinously holding of power button - it doesn't matter - once I tap to power once twice or continously - face recognition option on front camera start immidiately and flashlight on rear camera can not be used.


Kindly ask you to fix it and enable using flashlight on rear panel while front camera is active.

  • Hi @dron39,

    Are you on the latest 51.103 update?

    I've tried on a couple of devices and I couldn't reproduce what you are describing.

    Are you having this only on low light conditions? Or does it happen always?

    "Even if I bind flashlight to countinously holding of power button"

    I don't seem to have that option on my Zenfone 8. Can you please share a screenshot of your smart key settings?

    I also can't replicate your scenario. Do you get any kind of message telling you that the flashlight is unavailable when you press the power button twice?

    The smart key flashlight + face recognition combination can actually act up in small ways because AFAIK you can't trigger the camera and flashlight at the same time outside of the camera app. So when you double-press the power button it will sometimes recognize your face before activating the flashlight and vice versa. If it's the latter, you'll need to swipe up on the lock screen to trigger the camera again. But that's not really what you're describing.

    This is an annoying limitation. Every cheap Xiaomi can do this.


    @Irene2_ASUS enable face unlock, enable smart button for double tap to turn on torch, turn off screen, cover the front camera and try to enable torch by double pressing power button.

    Alex's gave correct advice how to reproduce it. Please try both to reproduce it.

    >>Are you on the latest 51.103 update?

    Yes, correct.

    >>Are you having this only on low light conditions? Or does it happen always?

    Usually I use flashlight in low light condition. But for example if I wear mask or do something which will increase time of recognition of my face - I will not be able to use flashlight until it's done.

    When it's daylight and I have no sunglasses or mask - face recognition works very fast (1 second or less), but usually nobody use flashlight when it's daylight :) . And if i wear mask or glasses it will try to recognize my face and during this procedure I won't be able to use flashlight on rear panel.

    >>I don't seem to have that option on my Zenfone 8. Can you please share a screenshot of your smart key settings?

    Sure. Please check attachment.


    >>Do you get any kind of message telling you that the flashlight is unavailable when you press the power button twice?

    Yes. Message is "Фонарик в данный момент недоступен" or something like "Flashlight is not available at the moment." in EN translation.

    >>I also can't replicate your scenario.

    Just enable face unlock recognition option. Bind twice tap on power key to flashlight and try to use it when your face in mask or sunglasses or not in front of front camera. You will see that message on your screen instead of flashlight.

    It was never happen for me when recognition of face was finished before flashlight was switched on. Even in daylight - I always can't use flashlight binded on power key if face recognition is on.

    Of course I can switch phone on, wait when recognition is finished and only then turn flashlight with power button. But it's nonsense. And what if it's dark or i wear mask or sunglasses and can not take them off at the moment.


    It looks like device can not use flashlight on rear camera while front camera is active, which was mentioned by @Alex's and it's nonsense for me, as many other phones on the market can do that...

    Kindly ask you to talk with your developers. I hope this can be fixed...

    @Irene2_ASUS @Gustav_ASUS

    The exact instructions are in @Alex's message.

    I have no idea why flashlight on rear panel can not be used while front camera is in progress. It's nonsense as many devices on the market have such option.


    So, no matter if it's day or night when face recognition is in progress - you won't be able to use flashlight. It's good if it's day time and I do not wear sunglasses or mask. Face recognition works very good and prompt by the way when it's day time. But it doesn't work and don't shut off front camera recognition in low light time (evening/night) when flashlight is really needed.

    When you push power button once/twice/thrice/continously - it will always turn screen on (because of first pressing to power button) and that's why there is no way that flashlight binded to power button will be switched on before (earlier than) face recognition is started. Because it seems that face recognition is starting along (in the same time) when display switched on.

    Yes, i'm on latest firmware .103.

    Screen of Smart button settings attached.


    I guess face recognition shouldn't be started if light sensor detect that there is not enough light to recognize face (evening, night etc.). And it should be tecetcted before flashlight is switched on to skip face recognition. Or just enable possibility to use flashlight when rear camera is active.


    Kindly ask you to discuss it with your software developers. I thnk such behavior can be fixed, as I told above - many phones even in low and mid range of different brands have possibility to use front camera and flashlight on rear - out of the box.

    It's nice that ASUS not only hears us but also listen to. This behavior was fixed in .115 update.

    But please check behavior of front camera while turning display off.

    For example phone in standby. Then I double click on "power" smart button - it will run torch(flashlight) and also turn display on. Then I again double click on "power" smart button - it will switch off torch (flashlight) and dispaly remain switched on. Then I once click on "power" smart button - dispaly will be turned off, but during this I see that face recognition seems to start recognition process because I see green point and circle around front camera.


    I think behavior should be 1) To not turn on display if "power" smart button pressed 1+ times or continously for flashlight. 2) To not run face recognition when phone sent to standby from display on state.

  • Thank you Asus for fixing this issue 👍

  • Face recognition should also work in dark environment.

    On OnePlus 7 there was an option in face unlock options to use screen light in dark. And it worked.
