How do you usually switch between apps on your phone? For me, pressing the three lines(or square) icon then, swiping & choosing between apps is too much of a hassle because I am a multi tasking nerd.
By using a simple yet least known feature of Android, you can quickly switch back and forth between two recent apps.
Double tap your android phone’s three lines (or square) icon button to switch to a recent app. Doing it again will take you back to the previous app. This way, you can cycle between two recent apps easily. Try it!
