The Samsung A3000 mobile phone is set with an alarm clock that doesn't sound or vibrate.

If the phone doesn't turn on after setting the alarm clock, it is suggested that:

1. Check whether there is an alarm clock icon at the top of the screen. If not, the set alarm clock may have been turned off by mistake.

2. Check whether the alarm clock is set to mute. Operation: Application-Clock-Click on the set alarm clock to enter the editing page and turn up the alarm clock.

3. Reset the alarm clock.

4. It is suggested to replace other self-contained alarm bells as much as possible.

5. If it is invalid, it is recommended to back up the information (contacts, text messages, photos, etc.). ) and try to restore the factory settings.

6. If the problem still exists, it is recommended to take the mobile phone, purchase invoice and maintenance card to the local Samsung after-sales service center for testing.
