There have been a few times I click on a website, it loads, and then my phone automatically switches to the AppStore to one of the 17,000 candy crush derivative games. Initially I thought I was inadvertently touching a banner ad, but it has now happened to other people I know too. Besides not going to these sites, is there a way to avoid this? I've fished through my settings and pop up block is on, but otherwise I don't see a setting that would stop this. It has happened both in safari and in the twitter app's built in browser. Has this happened to anyone else?
