Are there any currently-available apps that can be used to lock your screen? My wife's 521 has been having power button issues, so she's trying double-tap to wake. But she needs something to lock the phone with as well (just using time out is not practical in her case). Thanks!

there's a few apps available that can do this, perhaps the best is called 'Lock Screen' with it you can lock your phone simply by pressing a tile you can pin to your start screen. Try searching for 'Lock Screen' in the store. Hope this helps :-)

System Tiles has a tile to lock the screen. I use it all the time.
