Nokia's SMS beeps.

Hello, landlord. Method 1: Set the ringtone type in the situational mode to "Buzz" and the SMS ringtone to "None". After that, there will be no collapse.

Method 2: Enter Settings-General-Enhanced Accessories.

It should be no problem to set the single-listening headphones as the default. Anyway, the traffic headphones between us will crash by default, but not now. Because I found that when I played music outside, it wouldn't crash, so I wondered if it was a headset problem, and then it wouldn't crash after the above settings. You can try. By the way, if you set the single-listening headset as the default machine from the beginning, this problem will not appear.

Method 3: Information-Options-Settings-Others-Used storage-Memory card is changed to mobile phone storage.

I hope my answer can help you.
