Check whether your phone browser tracks three fingers at once with a free multi-touch test.
Place three fingers apart on the touch pad and hold them there. Watch the live count, then move the fingers gently without lifting them.
System gestures, touch settings and browser limits can interrupt tracking. A lower count is a reason to repeat the test, not proof of a broken digitizer.
No device permission is required.
Results are saved only in this browser for up to 24 hours. This single test does not replace a complete used-phone inspection.
