What does Blackberry SMS suggest?

I have never dropped my mobile phone, but yesterday it suddenly became like this, and there was no sound when I plugged in the charger. The only sound is music. I put music in my earphone, and it's still on, as if it's not plugged in. The strangest thing is that the normal state of the button next to it is that there is a ringtone icon on the ringtone screen, and the vibration is a ringtone icon with diagonal lines. But I didn't pull any icons. How to solve it. I'm from Hong Kong. Help me cry. .

Haha, does the landlord want to start with Q 10? How can I have a text message that doesn't ring? Unless my mobile phone is broken or I set the mute, my first mobile phone is BlackBerry, which started playing at 7 100g g. Now, don't worry, this will never happen. As long as it is a new machine and the volume is set, there must be sound.
