A few days ago my friend complained that her phone had randomly started popping up ads on its screen as she was just using it. She had to dig through the play store and find the 'recently used apps' to identify the culprit, which was a random app she'd downloaded that after a few days updated itself to start pumping out ads.
That is a distinctly android problem, and is an example of one I'm glad to avoid by sticking to iOS.
Perhaps she should be more selective with apps she installs? Also, how would this be exclusive to Android? iOS apps can have ads on them. Even if the feature is added with an update.
The ads weren't only displaying in the app, they were appearing over other apps. This is something that simply can't happen in iOS.
How does a standard user know whether a small app to e.g. manipulate photos (as in this instance) is going to be updated a few days later to show ads when it's not running? Shouldn't an end user be able to trust Google's app marketplace to not feed them junk like this?
