A52: After update One UI 6.1, mic doesn't work and mobile data not working

[TheLuma5]

After the ONE UI 6.1 update, the microphone stopped working. I can’t record audio messages, and I’m not heard during calls. However, when I record videos, there is sound (the upper mic works), and when I connect an external microphone, it works fine. Additionally, since the update, I no longer have mobile signal, and mobile data is not working.

Factory Reset your phone.

Hello, welcome to the Community, and thanks for reaching out regarding these behaviors. Before doing what @3Fees suggested, try the troubleshooting in the following guides first:
Microphone not working: https://www.samsung.com/us/support/troubleshoot/TSG10001652/
Mobile data not working/intermittent: https://www.samsung.com/us/support/troubleshooting/TSG01212956/

If the troubleshooting doesn't help, first try reaching out to your carrier regarding mobile data signal loss. If they are unable to help, and the microphone is not working, service and evaluation may be necessary.
