Multi-Touch Test
Press the pad with as many fingers as you can and watch each one appear. The counter shows how many touches your screen reports at once — and whether it keeps holding them. Nothing leaves this tab.
How the multi-touch test works
Every finger you place fires a touch event that carries a unique identifier and a position. This page reads all active touches each time the event fires, draws a dot at each position and counts them. The live counter is the number of fingers the screen is reporting right now; the peak counter remembers the highest number it has seen since you last reset, so a quick moment where all ten fingers land together is not missed.
How many touches should your screen handle?
Most current phones and tablets track ten simultaneous touches, one per finger. Budget and older devices often stop at five, and a few stop at two. The spec sheet number is the starting point, not the verdict: the real test is whether the count stays steady while your fingers rest on the glass.
Hold three fingers still and watch. A healthy digitizer keeps the number at three. One that flickers to two, or drops a finger and picks it up again, is losing contact — that is the early symptom a screen replacement or a warranty claim usually needs. Test the whole glass, not just the middle: the edges and corners are where digitizers fail first.
What this test cannot tell you
It counts and plots touches, so it proves the digitizer sees your fingers and keeps seeing them. It does not map the whole surface, so a single unresponsive strip can hide between the spots you happened to press. For that, paint the screen with your thumb in the touch dead-zone test. It also cannot measure pressure or precision, and on a laptop with no touch hardware it will simply report nothing, because a mouse click is not a touch.

Frequently asked questions
How many fingers should my phone recognize at once?
Most current phones and tablets track ten simultaneous touches, one per finger. Budget and older devices often stop at five, and a few stop at two. What matters is not the spec sheet figure but whether the count stays steady while your fingers rest on the glass.
Why does a finger sometimes disappear while I hold it still?
That is the touchscreen losing contact, not the page dropping it. A digitizer that lets go of a held touch is usually failing, though a dirty screen or a thick protector with an air gap causes the same symptom. Clean the glass and retest before you blame the panel.
Does a screen protector affect the touch count?
Rarely the count, sometimes the precision. Cheap protectors and trapped air can blur the reported position, and a badly seated protector can make the edges drop out. If the dropouts always happen in the same place, peel the protector off and retest.
My phone supports ten touches but a game only lets me press four. Why?
Because the game caps input itself; the hardware is not the bottleneck. The browser reads every contact the digitizer reports, so a game limited to a few fingers is a software decision, not a fault. This page measures the hardware underneath.
Is it normal for the count to jump when my palm touches the screen?
Usually, and it is not a fault. Palm rejection is applied by the operating system or the screen firmware, so the browser does not receive every contact raw — some devices filter a resting palm out before the page ever sees it, while others pass it through as extra touches. What matters for a used-phone check is whether the count jumps while your palm is nowhere near the screen; that is real trouble.
Can this test find a dead zone on my touchscreen?
Not on its own. It counts and plots where you touch, so a region that never registers shows up as points that refuse to appear there. For a full check, run the touch dead-zone test, which paints your swipes so a silent strip or corner becomes obvious.
Why does the page warn me on a laptop?
Because most laptops report no touch digitizer, and a mouse click is not a touch. The test needs real touch events. You can still check the page on a laptop by turning on touch simulation in your browser developer tools.
Is anything recorded or uploaded?
No. Touch coordinates are read in this tab and drawn on screen. There is no upload, no account and no analytics on your touches — closing the page erases everything.
