The customer is experiencing issues with the messaging app and has already performed a factory reset.

Once in settings, go to apps and notifications. Now go to app info. Once in app info, scroll down to the third option, which will be storage and cache. Now go to the messages app in that list. Yes. Now scroll down to the third option. That will be storage and cache. Once in storage and cache, press return to your storage. Don't worry. It won't delete your information, okay? Delete updates, yes? Once that's done, go back to settings, the regular settings app before you went into apps and notifications. Yes. And scroll down to the option that will be called system. Now go to system. Look up for reset options. Once in reset options, you will find an option that says reset network. Yes, Wi-Fi and Bluetooth. Mobile and Bluetooth, yes? Exactly, yes. That is what we need to do. Okay. Once that's done, turn off the phone, take out the battery, put everything back on and try to see if it works.

If you tell me that this is not working after you turn off the phone and turn it back on, I will have to take a look with the developers to see what may be the issue here.
