What's the matter with galaxy A7' s always no prompt tone when sending text messages?

According to your description, if there is no SMS prompt tone when you receive the SMS, I suggest you:

1. Try to reset SMS: Info-Menu-Settings-Notification Check, and select ringtone.

2. Check whether the phone is turned on in silent mode, and pull down the top curtain to turn the sound green.

3. SMS-Menu-Settings-Notification-Check.

4. Set the notification volume of the mobile phone (Settings-Device-Sound-Volume-Notification, and increase the notification volume).

5. Try to replace other built-in system ringtones.

6. Please back up the data (contacts, text messages, pictures, etc.). ), and then restore the factory settings (Settings-Reset-Restore Factory Settings).

If the problem still exists, please bring the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you carry out the inspection.

For specific inquiries about the service center, please visit.

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.
