I have an Android phone and I’ve never had this problem. I’ve only ever had android phones. I normally buy Samsung phones, but there were a few things I didn’t like about the new options. I’ve noticed on my new HTC phone I get ads when I turn it on. The ads aren’t intrusive otherwise. I downloaded an Adblocker app, but it seems to only be a browser. That’s not what I want. I’ll be reading this thread with interest.
