- 🛡️ Boot your device into Safe Mode to check system functions.
- 📉 Uninstall recently installed VPN or antivirus programs.
- 🔍 Check apps with location and network access permissions.
How do I uninstall an app that won't uninstall?
If the app doesn't uninstall through Settings, try deleting it through the Google Play Store. Find the app in the "Manage" list, tap it, and select "Uninstall." If that doesn't help, the app may have superuser privileges or be a system app.
Factory reset (Hard Reset)
A radical, but often effective, method for resolving software errors is a full factory reset. This procedure completely clears the device's internal memory of user data and returns the software to its original state. Before beginning, be sure to back up any important data, as it will be impossible to restore after the reset.
You can perform a reset through the settings menu if the phone responds to touch. Follow the path Settings → General settings → Reset → Factory data resetThe system will warn you about data loss. Confirm the action and wait for the process to complete, which may take several minutes.
