I am a vivo xplay model. After the system upgrade, functions such as how to open and display short messages have stopped running.

According to your description, I suggest you try the following actions to solve it:

1. Go to Settings-More Settings-Applications-All-Find the program and click to enter the information interface-try to clear the data.

2. I suggest you restart your mobile phone.

3. If the mobile phone system is not the latest, try to upgrade the mobile phone to the latest version. You can go to Settings-More Settings-System Upgrade-Check the update immediately, download the upgrade package according to the prompt, click Check Installation, and the phone will restart and automatically enter the upgrade mode.

4. It is suggested that you try to clear all the data, and click Settings-More Settings-Restore Factory Settings-Clear the mobile phone data. Clearing your phone data will format your phone, so you can back up your phone data, including contacts and photos, before this operation.
