Identify Ghost Touch Problems

Check Screen Response Delay
Touch latency refers to the delay between touch and response. A phone touch latency test online measures this delay accurately. Low delay gives a smooth experience, while high delay feels slow.
Check Display Colours and Dead Pixels
A dead pixel test shows solid colours across the screen so users can spot pixels that remain black, white or stuck on a single colour. A phone display test online free helps clearly identify display defects.
Check Brightness and Contrast Issues
