Frequently Asked Questions

How many simultaneous touch points do modern smartphone digitizers support?

Most modern capacitive touchscreen digitizers support between 5 and 10 simultaneous touch contact points with independent coordinate tracking and pressure sensing.

What causes ghost touches on Android screens?

Ghost touches can be caused by damaged digitizer flex cables, electromagnetic interference from counterfeit fast chargers, cracked glass micro-fractures, or static electricity build-up.

How do I test for digitizer dead zones?

Switch the tester to 'Drawing Trace' mode and scribble continuous diagonal grid lines across the entire display. Broken capacitive traces will reveal blank gaps where lines refuse to register.
