This can be a software issue or an app acting up. Can you restart your phone in safe mode and check if the same issue appears again?

thanks for the quick reply but will running the phone on a safe mode will affect the phone anyhow? and also i want to ask anout the SoundAbout App is it helpful in this case or should i unistall it?

Safe mode will allow only system apps to boot and run with the phone, and will disable any third party apps. Thus limiting any software interferences with basic phone functionality. For that app, I'm sorry I didn't use it before and don't know any information about it.
