Do you mean the mobile network is low or disconnected?
Could you show me a screenshot of the problem? e.g. try to load a website on Chrome, and show me the error message.
Please tell me the SIM carriers you have tried that have this problem,
and also try putting your SIM into other phones and check if there are still issues.
Please show me a screenshot of the signal strength (Settings > System > About phone > Status > SIM status)
What kind of locations does this problem appear? (inside buildings, on any transportation,..)
Have you checked in different locations?
For bluetooth volume low, please try turning on disable bluetooth absolute volume.
(Settings > System > About phone > tap "Build number" 7 times to enable developer options.)
Developer options > turn on "disable absolute volume".
If the problem still exists, please tell me the brand and model of your bluetooth device. Have you checked with other Bluetooth devices?
Please tell me when listening on which app, which song, does the volume sound low.
