ITest: Phone Diagnostics

Check your phone before buying used, after a repair, or when something stops working. ITest helps you test phone hardware and system functions, view device information, and check RAM usage in one place.

Run a guided sequence or choose individual tests. Follow the instructions, check how your phone responds, and confirm each result with Pass or Fail.

▶️ AUTOMATIC OR MANUAL TESTS

Auto Test opens supported checks in sequence, helping you work through the phone without searching for each item. Some tests need your input, a permission, or a system setting change. You confirm the results yourself.

Resume an unfinished automatic test or open a specific item in Manual Test to investigate further. After completing the test sequence, you can share a device report.

Useful for:

• Checking a second-hand phone

• Reviewing functions after a repair

• Investigating problems after an Android update

• Checking a camera, sensor, connection, or button that seems unreliable

📱 DEVICE INFORMATION AND TOOLS

View chipset, display, storage, battery, camera, temperature sensor, and system build information made available by Android.

Check RAM usage, find installed apps with the uninstall helper, and use home screen widgets to keep battery or device status visible.

🔐 PERMISSIONS YOU CONTROL

Camera and microphone tests need their respective permissions. GPS and Wi-Fi scans may require location access and, depending on your Android version, nearby Wi-Fi device permission. Bluetooth and SIM checks may also require relevant permissions.

Grant permissions only for the checks you want to run. You can manage denied permissions in Android settings. Notifications for widgets are optional.

UNDERSTANDING YOUR RESULTS

ITest is a diagnostic aid and does not replace professional inspection or certified testing.

Results depend on your phone’s hardware, Android version, manufacturer software, permissions, and how you perform each test. Pass records expected behavior at the time of testing. Fail records a problem you identified or a check that could not be completed. For warranty repairs, contact an authorized service provider.

PRIVACY AND ADS

Diagnostics run primarily on your device. No account is required. For details about data collection and use, see our Privacy Policy.
