As someone who has worked in second-hand electronics and as an engineer for Samsung, I've often seen users get confused by diagnostic features on their phones. With Android 15 introducing a new diagnostic screen, it’s crucial to understand what these tests entail and how they can help you maintain your device.
In the past, we used the *#0*# code to access the test menu, a feature many users were unaware of. However, Android's new feature aims to simplify diagnostics for everyone. Let’s explore the potential tests available on this new screen, their purposes, and what actions you might need to take based on the results.
Display Test
The display test checks for screen bleeding, dead pixels, and screen burn-in. These tests usually involve cycling through red, blue, and green screens to spot discrepancies. A white screen test, often performed by zooming in on the Google home page, is also common.
Screen Bleeding:
Screen bleeding appears as spots or blotches that change brightness over time, often caused by physical damage or pressure, such as keys pressing against the screen in your pocket. If you notice screen bleeding, consider getting a protective case or screen protector.
Dead Pixels:
Dead pixels appear as small points that don't display the correct color, showing up as white or dark spots. They can result from electrical faults or physical damage. While a few dead pixels might be tolerable, an increasing number indicates the need for a screen replacement.
Screen Burn-In:
Screen burn-in manifests as pink or off-color areas on the screen, best seen on a white background. It's often overlooked because many users keep their phones in dark mode. Unfortunately, screen burn-in usually requires professional repair.
Touchscreen Test
The touchscreen test ensures that the entire surface of your screen responds correctly to touch. This test can identify unresponsive areas, which might indicate the need for recalibration or repair. Keeping your screen clean and free from debris can help maintain its responsiveness.
Battery Health Check
Monitoring battery health is crucial for your device’s longevity. The diagnostic screen in Android 15 will likely provide insights into your battery’s current health, charging habits, and overall performance. Regularly checking your battery status can help you decide when it's time for a replacement.
Storage Health Check
A storage health check will provide details on your device’s internal storage status, helping you identify any potential issues that could slow down your phone. Regularly clearing out unused apps and files can help maintain optimal performance.
