I have a Kobo Glo HD with what I think is one or more IR sensors for the touchscreen. It is very sensitive, even a fly walking on the screen will activate it.

I bought an origami cover for the reader, so it can be put at an angle on the desk.

The combination of both mean that I need to turn it off, otherwise it would randomly switch pages when it is in my pocket.

I miss my first Kindle with its physical page turning buttons.
