You go to Settings-Apps-Manage Apps to check the built-in software of the mobile phone-Click to enter-If you see the word uninstall and you can click it, you can delete it; If you can't click it or it doesn't display, you can't delete it. If you want to delete this kind of file, you need to brush the phone or ROOT the phone, which may cause damage to the phone, and it is easy to cause system vulnerabilities, failures or virus infections, so this operation is not recommended.
