Samsung mobile phone why others often can't get through when calling, suggesting that they will make a point-to-point call, and the mobile phone doesn't turn off when there is a signal? What happened?

According to your description, I suggest you try the following actions:

1. Turn off the phone and restart it.

2. Check whether there is any incompatibility problem caused by downloading third-party software for setting.

3. If the problem still exists, it is recommended that you back up your data (such as contacts, text messages and photos) and restore the factory settings.

4. If the problem still exists after the above operation, please send your mobile phone, purchase invoice and maintenance card to Samsung Service Center for engineers to test your mobile phone. Please click the following link to view the specific local service center:
