Phone Checker — Test Any Phone in 2 Minutes

Buying a used phone? Selling yours? Phone Checker runs a quick, guided check of the whole device — screen, speakers, microphone, sensors, cameras, buttons, GPS and battery — and builds a clear health report you can save or share. In about two minutes you know exactly what works and what doesn't, before any money changes hands.

Built natively in Kotlin with a clean, modern dark design — fast, lightweight and fully private. Every test runs on your device, and nothing from a test is ever uploaded.

ONE-TAP FULL CHECK
• A guided wizard runs every test, one at a time
• Mark each part Working, Not working, or Skip
• Finishes with a complete Phone Health Report
• Perfect right before buying or selling a used phone

SCREEN TESTS
• Touch test — find dead zones on the digitizer
• Dead-pixel test — full-screen colours reveal bad dots or patches
• Multi-touch and refresh-rate check

SOUND & VIBRATION
• Loudspeaker and earpiece test
• Microphone test with a live loudness bar
• Vibration motor test

SENSORS
• Proximity, ambient light, accelerometer, gyroscope and compass
• Live readings so you can see each sensor respond

CAMERAS & MORE
• Front and rear camera live preview
• Flashlight, fingerprint sensor and volume buttons
• GPS test with live satellite count and location fix

BATTERY
• Live level, temperature, voltage and charging current
• See real-time values while plugged in and unplugged

FULL DEVICE INFO
• Model, chipset, RAM, storage, Android version and security patch
• Screen size, resolution and refresh rate
• Everything the phone reports about itself, in one place

SHAREABLE HEALTH REPORT
• A clean report image with a pass/skip result for every part
• Save it to your gallery or share it on WhatsApp in one tap
• Great for used-phone listings — show buyers the phone really works

100% PRIVATE — ON YOUR DEVICE
• No account, no sign-in
• Test results and reports never leave your phone unless you share them
• Camera is preview-only; the mic reads a level and never records
• No location, no photos, no audio are ever uploaded

HONEST BY DESIGN
Phone Checker reports only what the phone tells software. It cannot detect water damage, motherboard faults, or the true age of a battery — so it never claims a phone is "perfect." Use it as a fast, reliable check, not a guarantee.

PERFECT FOR:
✓ Checking a second-hand phone before you buy
✓ Proving your phone works when you sell it
✓ Testing a new phone the day it arrives
✓ Diagnosing a screen, speaker, mic or sensor problem
✓ Anyone who values a quick, private hardware check

Download now and know exactly what a phone can — and can't — do.
