I had my Moto X Pure a month and had continuing, strange problems. It would start texting, typing nonsensical phrases and when I touched it trying to stop it, green lines would start racing all over the screen. I persevered. Then the orange frame began and it would enlarge and reduce rapidly on its own. I just exchanged it for a new one. Migrate wouldn't work as my old one already had Marshmallow which renders migrate inoperable, purportedly. So when the store tech did the transfer of data from old to new using who knows what program it took well over an hour, I got email addresses from 7 years ago, 800 plus contacts! Also included responses to FB as a contact email. Hundreds of those. So now I am deleting those, but hopefully that will be the end of the problems.
