How do smartphones recognize touch input?

Smartphones (iPhone, Android)

It’s intriguing to think about how our smartphones detect touch. Most devices today use capacitive screens, but many might wonder how they function. After experimenting with various models, I’ve found some noticeable differences in their responsiveness.

The main principle seems to be the detection of changes in capacitance when you touch the screen. However, the technology varies across different brands and models. Some smartphones manage to track touches more accurately, particularly in different lighting environments.

Has anyone explored this topic? What are your experiences with touch sensitivity on different devices? Are there specific brands or models that you think excel in performance?
