IPhone users, I’m back with more hidden tips and tricks! In the notes app, if you type the greater than sign twice, you can link any other of your notes, which allows for quick access between two separate notes. We all know that you can shake your phone to undo, did you know that you can use three fingers to tap the screen to undo as well? This works in imessage too. This next tip works in both Google Maps and Apple Maps. You can double tap with your thumb to zoom in and out. So to zoom in, double tap and immediately slide your thumb downwards, and to zoom out, double tap and slide upwards instead.
