GoKawiilSamsung Galaxy phones include a built-in hardware diagnostics test
Samsung devices running Android 12 or later include a Phone Diagnostics tool under Settings > Device care > Diagnostics, letting users test individual hardware components or run all checks at once. The same diagnostics suite is also accessible through the Samsung Members app. A test run on a Galaxy S26 Ultra produced 22 separate checks covering the phone's hardware.
GoKawiil's interpretation of the reporting above, not reported fact.
For users experiencing battery drain, dropped calls, or general slowdowns after an update, this built-in tool offers a way to rule out hardware faults before installing third-party apps or visiting a repair shop. It functions as a health check rather than a performance benchmark, so it won't tell users how fast their phone is, only whether components are working correctly.
- Phone Diagnostics is found in Settings > Device care > Diagnostics on Galaxy phones with Android 12+
- Users can test individual components or run a full 'Test all' checklist
- The same tool is also available through the Samsung Members app
