About this app

Phone Tester: Device Info checks whether the parts of your phone still work, one simple test at a time, and shows what is inside the device.

Use it after a repair, before you buy a used phone, or whenever something feels wrong. Each hardware test asks one question and records if it passed or failed.

What you can test and see
• Run hardware tests: display and dead pixels, flashlight, loudspeaker, ear speaker, proximity and light sensors, vibration, Bluetooth, Wi-Fi, volume buttons and fingerprint
• Mark each test as passed or failed, read the test report and reset all tests
• Device and OS info: model, manufacturer, Android version, API level, security patch and kernel
• Processor, RAM and storage details
• Battery health, voltage, temperature and charging status
• Display resolution, refresh rate, density and screen size
• Front and rear camera info: megapixels, sensor size, flash and auto-focus modes
• All device sensors with their details, plus network and SIM info
• Installed user and system apps with version, package name and target SDK
• Use the app in 10 languages, including Arabic, German, French, Spanish and Japanese

Good to know
Some tests need the camera and flashlight, Bluetooth or Wi-Fi, and the app lists installed apps for the Device Apps screen. The app shows ads, and an optional purchase is available.

Test your phone in a few minutes and know what works.
