Hi anowarmolla55,
Could you tell us your firmware version?
Please also make sure that you have updated to the latest firmware version.

When this problem appears, are you using earphones/ phone's speaker/ bluetooth?
For earphones and bluetooth, please tell us the brands and models of them.
Please also show us a screenshot of your volume level when you feel the volume is too low.
Thank you 🙂
