My mobile phone doesn't have this

This is a problem. You really don't have this on your mobile phone. This is a problem. Most mobile phones now have this function. Why doesn't your mobile phone have this function? A mobile phone at this price is very reasonable. Besides, have you been cheated? Where did you buy the mobile phone? You must have been cheated directly. Trust me, you are right. Look at the question you asked. You can't lie. Haha, listen to me. That's right.
