A touchscreen is a touchscreen, right? Hardly! As MOTO pointed out in our recent Do-It-Yourself Touchscreen Analysis post, “All touchscreens are not created equal.”

With our simple test technique — which basically consists of using a basic drawing application and a finger to slowly trace straight lines on the screen of each device — it’s easy to see the difference in touchscreen resolution from one phone to the next. Results with straight lines indicate a high degree of sensor accuracy; less-precise sensors show the lines with wavy patterns, stair-steps, or both.
