Rooted or not: not

========================================
My zenfone is working, but the Fingerprint button and the right button (Touch keys) are not working anymore.
When I touch both buttons I can see that the phone senses it, but it doesn't do any work. For example to exit some third party apps you need to press the Fingerprint button, as the phone is with this problem I cannot exit these type of apps.
Another strange behavior is that notifications are not working anymore. Nothing appearing on top screen (System notifications) and Quick settings are not working anymore too.
Bellow are some screenshots:

Hi adrianoceano
Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.
