SE 2020 randomly switches between audio options while on calls
When making a call with my SE 2020, my phone randomly cuts out and switches between phone, speaker, and Bluetooth, and I have to manually choose the desired mode. If I start the call in speaker, it will cut me off and switch to phone. Even when I press the speaker button, the button lights up but stays on phone mode. It’s very glitchy. This does not happen during WhatsApp calls or when I have my ear buds in and use Bluetooth for the calls.
I brought my phone to an iPhone store and they told me my phone had no issues. Please advise!
iPhone SE, iOS 16
