The only thing I've got on my cellphone are money saving apps. If someone sees me staring at my screen, they might as well hang it up b/c I'm reading a book, and I'm blocking the rest of the world out in that way. I'll read books at any time I can sit still. I DO have a hard time putting books down, but I've always been like that. I read at my computer. I read on my phone. I read on my tablet. I'm always reading, and I always have 3 books open. 1 tech/science; 1 nonfiction; 1 fiction. I skip around with time spent on each during every day.
I have a fake email account on my phone that I never use except to sign up for crap I never intend to pay attention to at any point in the future and signup for apps. I go into it about once a week and delete things without even reading them.
Wait, there IS one place I pay attention to once a month. Authors have signed up for several places to give away free books each month, and I always look at that email to get the free code. I've been planning to sit down and join some other groups like that too. There are different free-each-month groups by genre, and I'll read most of them. It's kind of like Dolly Parton's Imagination Library for adults. They've even been starting some of them for young adults. My oldest granddaughter has one on her phone.
But as far as social media anything on my phone? Nope. Not Happening. It's a good way to let hackers get into your phone. I do like my money saving apps though--Receipt Hog, Checkout 51, Walmart, Walgreens, Target Cartwheel, and Ulta --First 3 get opened at least once a week, and last 3 get opened when I need to go to one of those stores.
But yeah. Those kinds of sites in that story want you coming back as much as possible. Advertising $$ depend on it.
