I have Wiko U Pulse Lite running on Android 7.0 Nougat. I would like to use Google Keep or Google Drive in split-window mode with the Phone application. This is because every time I perform a banking operation, I need to copy numbers and passwords from one window to the other, otherwise I need to recur to open and paper to use as my buffer for storing these data.

Is there a reason why the Phone application with its dialer keypad won't work in split-window mode? Is this fixed in later version of Google's Android OS?

    It works in Oreo in OnePlus 6, but the implementation of stock phone app can vary. i.sstatic.net/IR6fw.jpg // In which Android phone did you have that issue with split screen mode with phone app?

    A possible workaround is to try 3rd-party dialer (try Google's own app?) and check if this also happens on all Phone apps (which I somehow doubt), or only on Wiko's stock Phone app.

  • Thanks but I get an error message saying my device is not compatible with this app when I open the page in the play store. Thanks. Commented Feb 28, 2019 at 14:29

For an app to be allowed to work in split-window mode, there is a certain parameter android:resizeableActivity=["true" | "false"] that has to be set to true.

Since Android 7.0, this is true by default, but it's still possible to be set to false if the developer thinks the app will not behave correctly in split-window.

As @Andrew T. suggested in a comment, all you can do as a user is to find another phone app that allows split-window.


If Developer options is enable, you can set "Force activities to be resizable" to On.

Settings -> Developers options -> Force activities to be resizable

Then, restarts the phone. It has worked for me when there were apps not developed to use split screen by default.
