The customer is experiencing issues with message notifications and volume control after a software update.

Okay, with the messages thing, I can help you right now. So you can go to settings. Once in settings, go to apps and notifications. Once in apps and notifications, go to see all apps. Okay, once you're in see all apps, look up for the messaging app, of course. Okay, once you're in the messaging app, scroll on to the third option and the option that's going to be called storage and cache. Clear storage. Okay, it won't delete your messages. Don't worry. Okay, cleared. Okay, now the messages should come with no problem. Please test it thoroughly and on the other issues, I will have to report them because it's not something really normal.
