In essence, these changes make it hard for users to zoom out the Fire Stick TV when it zooms in accidentally. Previously, if your Firestick zoomed in, all you had to do was hit Settings on the home screen and navigate to Calibrate Display. While there, you just needed to press the Up and Down buttons on your remote to zoom in or out. However, with the recent OS update from Amazon, this option is no longer available. This makes the process of Firestick zoom out very problematic.
