If you have read that your iPhone takes a snap shot of your iPhone’s current screen every time you press your home button, and now sweating buckets in-case your parents or partner is going to end up reading something that’s cleverly stored in your iPhone – don’t panic.
Unless the iPhone is in the hands of a Mac expert who has the time and energy to look for you screenshots then I really wouldn’t worry, it’s really not that simple.
We know that the home button will be pushed a few times throughout your day, as of course it is one of the most important buttons on the iPhone, but don’t be paranoid and relax your iPhone is your friend not your enemy and is not spying on you.
