Windows Phone screen zooms in unexpectedly...

I found that my Windows Phone device occasionally would zoom into a state like this:

For the longest time, I thought it was a bug on my device and the only way I thought I could get out of this state was to reboot my device.  But I was totally wrong. This is actually a feature!  If you head over to SETTINGS and then EASE OF ACCESS, you'll see a subheading called SCREEN MAGNIFIER and on my devices, it's ON by default.  But read the description of the feature --- the zooming, or magnifying feature, activates by one double-tapping with two fingers.  I guess I must have been triggering this on accident in the past.  Anyhow, it's a cool feature. Now that I know about it.  Double-tapping once again with two fingers will get you out of the magnifier instead of you forcefully rebooting the device.  Glad to have finally figured this out for myself...
