For the average user, diagnosing potential hardware issues on their device can be a somewhat complicated process. However, Google wants to make this easier by integrating on-device diagnostics into Android 15. This will allow you to know if your phone has a fault in a key part before taking it for technical service. This joins privacy options such as Repair Mode which Pixels and some other brands have.
The on-device diagnostics tool was spotted by Android Authority in the latest Android 15 Beta 3. The option is not available by default, but it can be enabled. Once you have it, you can access it by going to Settings > System > Device Diagnostics.
The on-device diagnostics tool has two main display items: “Component health” and “Evaluation mode.” The “Component health” section will allow you to run manual tests on your phone/tablet. On the other hand, “Evaluation mode” allows you to evaluate your current device using another device.
This is what the Android 15 on-device diagnostics tool would be like
Starting with “Component health,” it includes screen integrity and touch performance tests. It also allows you to check the current status of your battery and storage chip. Regarding the battery, it shows data such as the percentage of remaining capacity, manufacturing date, first date of use, and even the number of charging cycles.
There are also entries for “serial number” and “part status.” These ones do not seem to be functional currently. Then, in storage status, you can check the remaining useful life of the storage chip, as well as its total capacity.
Moving on to “Evaluation mode,” it is a test where you will have to use another supported device. The process begins with scanning a QR, and some tests require internet access.
Useful to detect issues before going to technical service
Overall, the Android 15 on-device diagnostics tool will give you a pretty good general idea of the status of your device’s hardware. For example, it can help you detect potential issues with dead pixels, light leaks, or discoloration on screens. Also, know how healthy your battery is. It’s noteworthy that there are some third-party apps that do similar tests. However, having a tool integrated directly into the OS is a welcome addition.
