Water Eject vs Dead Pixel Test

Dropped your phone in water? Don't wait for the damage — eject it now. Water Eject: Phone Tester clears water out of your speaker with sound waves and gives you a complete hardware checkup: screen, touch, microphone, sensors, Face ID — all in one app. WATER EJECT IN SECONDS A specially tuned sound wave pushes liquid out of the speaker grill — the same principle as the water lock on Apple Watch. No rice, no disassembly, no service center. Run it right after your phone gets wet and repeat until the sound is crisp again. CHECK EVERY PART OF YOUR PHONE • Water Eject — remove liquid from the speaker with one tap • Speaker & Audio — test sound output and microphone response • Screen — full-screen color tests to spot dead pixels and backlight issues • Touch & Gestures — visualize every touch and multi-touch point • Motion & Orientation — live accelerometer and gyroscope readings • Environment — compass and proximity sensor • Navigation — GPS and location accuracy • Biometrics — Face ID and local authentication check PERFECT FOR • Buying a used iPhone — verify the hardware in minutes, right in front of the seller • A phone that just got wet — eject water before it causes real damage • Strange behavior of the screen, sound, or touch — diagnose it before paying for repairs • Developers and tech enthusiasts who want real sensor data REAL DATA, NOT SCORES No abstract "health ratings." You see live readings straight from your iPhone's hardware — and judge for yourself. PRIVATE BY DESIGN All tests run on your device. No account, no signup required.
