The only time I spend on my phone (outside of using it for its designed purposes) as in messing wit trackball color or housings and what not is late at night when my fiance is in bed. (I don't sleep much) or boredom time when I have free time. I spend a lot of time on it but usually texting emailing or using one of the apps but not more than necessary it certainly doesn't interfere with anything just helps me be more productive
