Yes. I work on my laptop, check facebook on my phone while having lunch or playing with the kids, watch movies with the kids during the day. Almost my entire day is spent in front of a screen most days.
I don't have any doubt that I am getting too much screen time, but on the laptop not on the phone. I don't use the phone much at all. And here I am, fairly late in the evening still on my laptop. Bit of a bad habit I guess.
