Seems, Cortana is able to find two “Settings” apps on some Windows Phone devices. This is how it works,
1. Open Cortana.
2. Ask Cortana to “Open Settings”.
3. She shows you this screen asking you, which settings to open, whether 1 Settings or 2 Settings.
If you ask to open 2 Settings, it opens the normal settings of your Windows Phone. But, if you ask for the 1 Settings, it just shows the Start Screen.
It has been has tried on Cortana Alpha in the India on a device running Windows Phone 8.1 Update 1. I tried on my two devices running GDR1, but no luck for me. Try and see whether you can find it yourself.
Since, this First settings app takes to “Start Screen”, may be it appears in Windows Phone 8.1 GDR2 with some ‘important settings for Start screen’. GDR2 may come out in October with many new features along with broader hardware support. What do you think?
Thanks Surya for the tip. Cheers!!
