Phone Tests

Test your phone's vibration, compass, GPS, motion sensors, NFC, speaker and charging speed.

Tests

Sensors and motors

Open these tests on your phone. The vibration test runs the vibration motor in different patterns, the compass test shows your heading and warns about magnetic interference, and the gyroscope test shows rotation, tilt and a bubble level. The gps test reports your position, accuracy and speed without sending your location anywhere.

Charging, NFC and speaker

The charging speed test measures how fast the battery fills so you can compare chargers and cables. The nfc test reads NFC tags on Android, and the phone speaker test checks the top and bottom speakers. After a splash, water eject helps clear the speaker grille.
