Why did someone call me Samsung s5830 and I didn't answer it? Sometimes messages will automatically reply to others.

Because you set SMS rejection, that is, you refuse to answer the phone and send a text message immediately. The contents include I am driving, I am in the cinema, I am in class, I am in a meeting and so on. ~ ~ ~ You can also make your own words, and you can click Create.

This setting can be set in SMS Rejection in Settings and Call Settings.

I also use Samsung S5830.

If you want to give me a reward, you can ask me again, if you don't understand.
