1, system privilege restriction: Some apps may get system privileges when installing, and these privileges may restrict users from uninstalling apps.
2. Pre-installed apps: Some cell phone manufacturers pre-install some apps at the factory, and these pre-installed apps may not be able to be uninstalled in the usual way. If Blueberry Video is one of the pre-installed apps, then it may not be possible to uninstall it directly.
3. App conflicts: In some cases, other apps or system components may conflict with the Blueberry Video app, making it impossible to uninstall it properly.
