This all-in-one smartphone diagnostic page combines automatic browser readings, full-screen visual checks, performance measurements and guided physical confirmation.
Touchscreen and multi-touch test
Open a true full-viewport touch grid to trace edges, corners, rows and columns, identify touchscreen dead zones, detect ghost touch behavior, count simultaneous fingers and inspect pointer pressure.
Display, dead pixel and refresh-rate test
Use black, white, red, green, blue, grayscale, gradient, checkerboard and fine-line screens to inspect stuck pixels, screen burn-in, tint, banding, flicker and frame stability.
Accelerometer, gyroscope, orientation and compass
Measure phone movement, gravity, shake response, angular rotation, portrait and landscape tilt, compass heading and magnetometer-related orientation behavior where the browser exposes it.
Ambient light, proximity and environmental checks
Read direct lux or experimental sensor values when available, with clearly labeled camera-assisted light and near/far response fallbacks plus GPS altitude-based pressure reference.
Camera, flashlight, microphone and audio
Test front and rear cameras, available lenses, rear LED torch on/off constraints, microphone level and waveform, main phone speaker, stereo left/right channels, frequency sweep and earpiece response guidance.
GPS, NFC, Bluetooth, USB and network
Check location accuracy, altitude, speed and heading; scan NDEF NFC tags; open Bluetooth LE and WebUSB choosers; and inspect browser-visible Wi-Fi, cellular and connection information.
Battery, charging, vibration and hardware buttons
Monitor battery percentage and charging events where available, inspect any vendor-exposed advanced battery fields, trigger vibration patterns, and follow safe manual checks for volume, power and mute controls.
CPU, RAM, GPU and storage diagnostics
View browser-visible architecture and logical cores, run bounded processor and memory benchmarks, identify the WebGL renderer, inspect graphics limits, estimate website storage quota and test private storage read/write speed.
