Thanks Rayan for sending these in and guess what, even I didn’t know about these two interesting Windows 10 for Phones features.
1) That expandable action center is great and also the fact that you can access so many quick-access buttons by expanding it. But if you long press on any of these quick-access button it will take you to the settings of that button. For example in above screenshot I long pressed on “Brightness” quick action button to go to “Brightness” settings.
2) If you copy text and then lock your phone on Windows 10 for Phones you don’t loose it. What that means you can unlock your phone and can still find the text copied and retained to clipboard to paste it anywhere you want. That looks quite useful.
