I often get a short message. When I open the text message and look down, my mobile phone will vibrate inexplicably. I can only buckle the battery. Who knows what the problem is?

Enhance SMS, some mobile phones have this function and some don't. Ordinary SMS can only send text, and enhanced SMS can send some simple sounds and pictures, not MMS. What you said is called "flash shock", which is a ringtone in imy format. Some of them can't send enhanced short messages, so they can't see pictures and ringtones when they receive them.
