Samsung mobile phone pops up to send text messages or something.

According to the description, it is recommended that you:

1. Uninstall the latest third-party software you tried to install.

2. Check whether the mobile phone has a system update push, and upgrade the mobile phone to the latest system version.

3. Back up data (contacts, text messages, photos, etc. ) and try to restore the factory settings.

If the problem still exists, it is recommended that you take the machine, purchase invoice and warranty card to the local Samsung after-sales service center for testing.
