Every time you swipe, tap, or pinch the screen of your phone, you are using a piece of technology called a Digitizer. This is a thin, invisible layer on top of your screen that can feel the electricity in your fingertips. At Hardware Tester, our Digitizer Lab is designed to help you see if your screen is feeling every touch correctly.
Our mission is to help you find "dead spots" or "ghost touches" before they become a big problem. Whether you have a brand new tablet or an old phone with a cracked screen, our Multi-Touch Lab provides a clinical way to audit your hardware's accuracy. It's like a playground for your fingers, but with professional data at every step.
In the old days, phone screens could only feel one finger at a time. Today, modern screens can feel 5, 10, or even 20 fingers at once! This is called Multi-Touch. It is what allows you to pinch the screen to zoom in on a photo or play games with complex controls. Our tool tracks your "Max Simultaneous" touches to show you exactly how many fingers your screen can handle.
Have you ever seen your phone start opening apps or typing letters all by itself? This is called Ghosting. It usually happens when the screen is dirty, wet, or if the hardware is starting to fail. Our Digitizer Lab monitors your screen for any touch signals that aren't actually coming from your fingers. A "CLEAN" score means your hardware is perfectly healthy!
Update: Feb 2026 (v4.0.12)
Added support for ultra-high 240Hz touch sampling rates. Improved the "ghosting" algorithm to filter out accidental palm touches. New "Full-Screen Audit" mode for checking the very edges of your display.
Update: Dec 2025 (v3.5.0)
Introduced "Pressure Sensitivity" detection for devices with force-sensing screens. Added a live Hz counter to see how fast your screen is talking to your fingers.
Find Dead Zones
Sometimes a small part of a screen stops working. Use our "Full-Screen Audit" and draw lines over the whole screen. If the lines break, you've found a dead zone!
Check Screen Protectors
A thick glass screen protector can sometimes make your screen less sensitive. Use our "Sampling Rate" test to see if your phone is missing your touches.
Gaming Precision
If you play competitive mobile games, you need a high sampling rate. Run our test to make sure your device is ready for fast action.

Expert Tip: If your screen feels "sticky" or slow, try turning on "Touch Sensitivity" in your phone's display settings. Then run our test again!

Why does it only feel 5 fingers at once?
Many budget phones and older tablets are limited to 5-point multi-touch. This is perfectly normal! Some high-end gaming phones can handle up to 10 or even 20 points.
What is a "Dead Zone"?
A dead zone is a part of the screen that doesn't react when you touch it. This is usually caused by a physical crack or a hardware problem inside the screen.
Does water affect the test?
Yes! Even a single drop of water can make the screen think you are touching it. Make sure your hands and the screen are dry for the most accurate audit.
