Android is full of wonderful little touches here and there that we either forget or have never come across in the first place. One of these is the very neat time-saving ability to double tap the Recents button to switch to your previous app. The functionality was added way back in 2016 with Android N, and has been saving us time for two years now. If you didn’t know about it though, and many of you did not, this will be your new favorite thing.
