Why does Samsung automatically send text messages to the other party as soon as it hangs up?

First find someone else's mobile phone card and put it in your mobile phone to see if there is such a situation. If there is something wrong with your mobile phone settings, just modify the settings. If not, it means that it is a problem with your mobile phone card, and looking for customer service should be able to solve it; It is also possible that the other party has set the anti-disturb mode.

Send a text message after canceling hanging up. The specific method is not clear about the model of your mobile phone (whether the operating system slides, etc.). ). It may be in the settings or in the call settings, and it is designed for business people. If it's a phone call from a customer and it's inconvenient for you to listen, just send a message politely. If you just like hanging up the phone instead of explaining that it's off, that's good.
