Free phone test

Touch Screen Test

Drag across every cell to find dead zones, plus a multi-touch finger check.

Drag to fill the grid0% covered

Press with two or three fingers to check multi-touch.

How did it look?

Any cell that won't fill in, or a finger the screen can't see, points to a digitiser fault.

This is a quick self-check, not a full diagnosis. Physical and board-level faults need a proper bench test — which we do free before any repair.

More free tests

Screen test

Fill the screen with solid colours to spot dead pixels, stuck pixels and patches.

Speaker test

Play clean tones through the left, right and both speakers to check for crackle or silence.

Mic test

Speak and watch a live level meter respond — confirms the mic is picking up sound.

Camera test

Preview the front and rear cameras live — check for blur, spots or a black frame.

Sensors test

Fire the vibration motor and tilt your phone to see the gyroscope respond live.

GPS test

Get a live location fix and see how accurate your GPS reading is.

Face/Touch ID

Confirm your device's biometric sensor — Face ID or Touch ID — is available and recognised.

Charging test

Plug in your charger and watch the live battery + charging status flip.

Flashlight test

Switch the rear LED torch on and off to confirm the flash fires.

Bluetooth test

Scan for nearby Bluetooth devices to confirm the radio is alive.
