This guide will show you how to put your Android in service, maintenance, or repair mode. Service mode is a secret diagnostic menu for troubleshooting, while maintenance and repair modes are designed to protect your data when your device is being serviced. We will cover the methods for various devices, including using special codes for service mode and the built-in features on Samsung and Google Pixel phones.
How to access special modes on your Android phone
Follow the steps below for your specific device and the mode you wish to enter, whether it’s for diagnostics or for secure repairs.
Method 1: Using a service mode code
- Search online for your device’s service menu code. For example, search for “T-Mobile Galaxy S22 Service Menu Code,” replacing the carrier and model with your own.
- Take note of the numeric code you find, as you will need to enter it precisely.
- Return to the Home screen on your device by tapping the Home button.
- Launch the default Phone app from your home screen or app drawer.
- Enter the service code you found using the on-screen number pad. Note: If you have a Verizon Android device, this method may not work. You might need to sideload a diagnostic app, but be extremely cautious as they can contain malware.
- Tap the call button. The app may appear to crash, which is normal. Your phone will then display diagnostic information like GSM status, Cell ID, or IMEI certification. Some devices may show buttons for specific tests you can run.
Method 2: Using maintenance mode on a Samsung device
- Navigate to Settings and then select Device care. Samsung recommends backing up your data before proceeding.
- Tap on Maintenance mode. You will be prompted to create a backup if you wish.
- Tap the Turn on button and follow the on-screen instructions. If you do not have a lock screen enabled, you will be required to set one up to continue.
- To exit this mode, return to Settings > Device care > Maintenance mode.
- TapExit, followed by Restart. You will need to enter your lock screen password or pattern when prompted. If you need to restore your data, navigate back to the Maintenance mode menu and select Temporary cloud backup, then tap Restore.
Method 3: Using repair mode on a Google Pixel device
- Open the Settings app and scroll down to tap on System.
- Tap on Repair mode and follow the on-screen instructions. You will be prompted to enter your security PIN, pattern, or password.
- Allow the phone to restart. Once it reboots, it will automatically be in repair mode.
- To disable repair mode after servicing, go to Settings > System > Repair mode.
- Enter your security credentials again and let the phone restart. When it boots back up, it will be out of repair mode.
Understanding and using your phone’s service mode can empower you to become your own first line of tech support. By accessing diagnostic tools, you can check cellular signal strength, test hardware components, and review system information. This can help you identify minor issues yourself, potentially saving you the time and expense of a trip to a repair shop for a problem you can easily fix.
Furthermore, using maintenance or repair mode is a critical step for protecting your privacy. When you hand your phone over for service, these modes create a safe, separate environment that shields your personal data, including photos, messages, and financial apps, from being accessed by technicians. This provides essential peace of mind, ensuring that your sensitive information remains secure while your device gets the repairs it needs.
