How can I lock the screen from within the Windows 10 Mobile app?

Question

I was searching through UWP API Reference and I didn't find any way how to Lock the device from within app or with Secondary Tile.

And I am frustrated, because there is a proof that it can be done. I don't want to make any advertisements here but for example this app: https://www.microsoft.com/en-us/store/apps/quicktiles/9wzdncrfhzts Can create secondary tile that just locks the screen.

How can I do it myself?

Thanks.

I don’t think it is possible with the UWP libraries. I tried to do an app able to lock the screen and had to give up few week-end ago.

Reading the review of the application you mentioned it seems it use a “hack” to achieve the lock screen but it seems to have side effects:

• “After locking phone, the device is very hot and battery down very fast. Please fix it.”
• “However after lock screen, it cause phone very hot and extreme battery drain”
• “ sometimes after i lock the screen, the battery is getting hot until i unlock the phone”

I’m also very surprise that UWP do not offer such functionality…
