S21 / 21 plus call issues

[jssblr]

Hi, i am unable to hear incoming calls on my s21 and s21 plus after android 12 update now and then.

Are you guys facing this issue and any solution 

[saltaf]

No I am not facing any issues such on my S21+, try clearing cache or do cache partition wipe. Might resolve your issue

Dear Samsung member,

Greetings from Samsung customer support.

Thank you for sharing your concern. We acknowledge your query and apologize for the same And please follow the easy troubleshooting steps which might help to solve the issue.

Make sure there's nothing covering the receiver at the top of the front of your device. A poorly placed screen protector is one of the most common causes of low volume or no volume during calls.
Make sure the receiver grill is not blocked with dust particles. Request customer to please clean it and check.

Ensure that the volume on your device has been set to the highest level during a voice call. You can also try tapping on the speaker to see if this improves the call volume.

During a voice call, press the volume button of your device, to open volume settings.
Tap and drag the call volume bar to left or right to increase the call volume.

Call quality & sound problems

Step1: Navigate to apps screen and tap on Settings.
Step2: Tap on Accessibility.
Step3: Tap on Hearing enhancements.
Step4: Disable Mute all sounds, If enabled.

In case the issue still occurs. Please register your concern in Samsung Members Application (Open Samsung Members Application > Get help > Send Feedback >Error report).

Thank you for writing to Samsung.

Warm Regards,
Samsung Customer Support
