How to switch between apps in Windows Phone
Even after enough prolonged use of their first device with Windows Phone, it took me some time to find a quick way to switch between running applications. Initially, I just pushed the button for return back, and so, until then, until I get to my desired application. It works but was way much better, and fortunately, one day I discovered it, albeit by chance. It works on the same principle as Alt + Tab in Windows.
In the Windows Phone «Back» button is the key to switching between apps. This button functions by analogy with the Alt + Tab keyboard shortcut in the desktop versions of Windows. You have to press and hold the «Back» button. After that, scale interface, the currently open application will be reduced and on the screen you will see a list of all open apps.
Slide your finger left or right until you find the desired app, and then click on the preview of this application. Below is embedded a video that demonstrates how it works:
I’m curious, how many in your case it took time before you find this function?
