The mobile phone is Samsung's, but it always rings automatically every few minutes recently. The system sound is a whistle. What to do?

From your description, in this case, I suggest you:

1. Restart the machine and try.

2. Check whether the mobile phone is set with a timer alarm clock or a schedule reminder.

3. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-General-Reset-Restore factory settings).

If the problem still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
