Because I have an HTC One M7 with a dead light sensor, so all my dark images now have a lovely tinge of purple.
And more importantly, I have a two year old daughter who likes to steal Daddy's phone from his pocket and play with it. So far no phone calls or texts to China, however she has managed to set me reminders in Google Keep to remember to do kkkkjdfjjkdkkjfkfj at 9am, followed up by iouweoruioweruoiereruoiewru also at 9am.
So, if Daddy could get a nice, shiny new Nexus 6p, I could donate the old M7 to her, SIM-less, and thus protecting the world from random facebook posts of dinosaurs, Dora the Explorer, or one of our cats butts.
