At certain times when swiping or tapping your fingers on the touchscreen of smartphones, anyone feels a slight pain, tingling, burning or uncomfortable sensation on your fingers? Assuming the fingers are clean and not wet.

Any thoughts appreciated.

Perhaps 1 hour per day. I used to play games on the phone quite often previously but don't do that anymore these days. Since most smartphones rely on capacitive touch screens to operate, this will involve the electrical properties of the body as the fingers are conductive. There may be some side effects with prolonged use I guess.
