Test any phone in 2 minutes — before you buy or sell
Phone Checker is in closed testing on Google Play. Getting access is instant — just join our testers group with the same Google account you use on the Play Store.
If the group page looks like the screenshot below, you are simply not signed in yet. Tap Sign in first — the Join group option appears straight after.

Important: open both links with the same Google account you are signed into on the Play Store. Google grants closed-testing access only to that account — a different email will not be able to open the app. If the app shows “not found” right after joining, wait an hour and open the link again.

A clean report image you can save or send — perfect for used-phone listings
Phone Checker runs a quick, guided check of a phone's hardware and builds a clear health report you can save or share. In about two minutes you know exactly what works and what doesn't — which is exactly what you need before handing over money for a used phone, or when proving your own phone is in good shape to a buyer. It tests the touch screen and display, loudspeaker and microphone, vibration and flashlight, five sensors, both cameras, the fingerprint reader, volume buttons, GPS and battery. Built natively in Kotlin with a clean dark design. Private by design: every test runs on your device and no result is ever uploaded unless you share it yourself. Phone Checker is currently in closed testing and available to registered testers only.
