Hello, the ringtone of the mobile phone notification has been turned to the maximum, but the SMS prompt tone is still very small and almost inaudible. The incoming call sounds normal. What is the reason? Dear Samsung users, hello:

According to your description, I suggest you:

1, turn on the phone settings-sound-volume-media/ringtone/notification/system-resize for observation.

2. If the volume of the mobile phone automatically decreases after adjustment, please back up the data and try to restore the factory settings.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test.

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.

If you need help, please visit support.samsung.com.cn, and official website will provide you with multi-channel service support!
