Basically most of the time the fingerprint unlocking works nicely, but sometimes, it just refuses to read the finger, mostly without even vibrating to indicate it couldn't read the finger. and the solution is inconsistent either, sometimes I unlock it with pattern, then close and it reads the fingers correctly, sometimes it refuses to read a specific finger so I use another one (I have 3 fingerprints), and sometimes it just continues to not work for some minutes. It happenes pretty rarely but happened for the past half year even after several updates, but i must say it never happened in the first ~3 months after I started using Zenfone 9 in February 2023.
This is not the first post about this issue, and unfortunately there is no clear pattern on why this happenes.
Model Name: Zenfone 9 (I love this phone thank you so much Asus)
Firmware Verion: 33.0804.2060.165
Rooted or not: No
Frequency of Occurance: Twice a week on average. (happenes with screen on or off)
Type of screen off-unlock mode: Press or touch
If I go to the fingerprint settings after it happenes, it detects all fingerprints correctly.
Not using face recognition.
When the problem occurs it can sometimes say I did too many attempts and force me to draw pattern.
Thank you in advance
It seems like you're experiencing intermittent issues with the fingerprint unlocking feature on your Asus Zenfone 9. These problems can be frustrating, but there are several steps you can take to troubleshoot and potentially resolve the issue:
1. Clean Your Fingerprint Sensor:
2. Re-register Your Fingerprints:
3. Check for Software Updates:
4. Test Different Finger Placement:
5. Delete and Re-add Fingerprints in Different Lighting Conditions:
6. Remove Screen Protectors or Cases:
7. Reset Fingerprint Settings:
8. Safe Mode Testing:
9. Contact Manufacturer Support:
10. Monitor for Patterns: - Keep track of when and under what circumstances the issue occurs. Note if there's any correlation with specific apps or actions you take before the problem arises. This information can be valuable when seeking help from support.
Remember that intermittent issues with fingerprint recognition can be caused by various factors, including software glitches, sensor cleanliness, or even hardware-related issues. It's important to troubleshoot systematically and, if necessary, seek professional assistance if the problem persists.
did everything on this list before even posting, except the safe mode, but since the problem may be nonexistent for as long as two weeks so it would be hard for me to use the phone in safe mode only, besides, I dont suspect any app to cause such problem because I use a limited amount of simple apps like messeging and browser, no weird launchers or fingerprint locking apps or whatnot.
the most logical of all is dirty fingers or fingerprint sensor but I always clean it when that occurs and that seems to have no effect.
