This morning, my mobile phone got a call from my mother for no reason, and then I answered the phone, but no one answered, so I hung up.

Don't worry, it's nothing. There is only one reason for this:

Aunt accidentally touched the dial pad, and your phone record was in the phone call record, so it called your name and dialed out. Of course, my aunt doesn't know that the phone has been dialed out. If you don't believe me, you can check when you received your aunt's phone call, and then you can ask your aunt when her phone record was dialed to your mobile phone, and everything will be clear after checking.

In fact, I have received many such things before, and it is not good to think and worry blindly. Make a phone call and do what you have to do as long as nothing happens.

Hope to adopt!
