Hi
dinkarks321,
Is your phone ZB601KL or ZB630KL?
Please provide your firmware version: Settings > About phone > Build number.
Could you describe in more details about the"fingerprint sensor sounds issue"?
For slow charge problem, are you using the original charger? Please try with new cables and check again.
The fast charging appears after a few minutes when you plug in your charger. Please check your lock screen after a few minutes.
If the problem still appears, please tell us at which battery levels does fast charging not work.
Thank you
🙂
