Touch screen won't easily tap on

In recent weeks, my Vivioactive 4 won't easily activate the backlight when I tap on the screen.

Sometimes I have to tap it 2 or three times or hit it harder than was normal in the past.

This seems to have started after a recent update.

Any ideas how to fix this?
