Hello, why is my 7 102 message very quiet, the vibration is very weak, and the bell is not too loud?

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

1. It is recommended that you go to Settings-Sound-Volume-and turn the notification volume to the maximum.

2. I suggest you go to Settings-Sound-Vibration Intensity-Notification to make the maximum adjustment.

3. Do you have mobile phone security guard software or some third-party software programs installed in your mobile phone? If so, try uninstalling it.

4. It is recommended that you restore the factory settings of the machine, as follows: Setup-Reset-Restore the factory settings (however, since restoring the factory settings of this machine will lose all the data in your mobile phone, it is recommended that you back up important data such as phone book, videos and pictures in advance).

5. It is recommended that you try to upgrade the firmware. (Settings-About Equipment-System Update)

If there are still problems through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung service center, and the engineer will check and deal with the machine.
