Slow screen unlock with fingerprint

edited September 2020 in ZenFone 5 Series
Model: ZE620KL
Firmware/APP Version: Android 10
Frequency of Occurrence: All the time
Rooted: No
APP Name:

Started after I upgraded to the latest Android 10.
The fingerprint scanner used to work blazingly fast, but after the upgrade it's significantly slower.
Another thing I've noticed is that while unlocking the phone the lock screen wallpaper glitches but then switches to the homesl screen wallpaper. Super annoying.
Anyone's experiencing similar issues?


  • Hi sorantis,

    Could you help us confirm whether your phone is ZS620KL or ZE620KL?
    Thank you :)
  • Yes, it's Zenfone 5z, ZS620KL
  • I just realized that I posted in Zenfone 5. Could you please move the topic to Zenfone 5z?

    Hi sorantis,

    Please try removing your previous fingerprint data and set them up again.
    If the problem still appears, please tell us does it become slow when trying to unlock when the screen is on or off?
    How long does it take for it to unlock?
    Could you show us a short video of the lock screen wallpaper glitch?
    To share videos, please upload it to ASUS WebStorage ( and share the link with us.

    Thank you :)
