Not a dumb phone but if you want a decent cheap smartphone that isn't a complete piece of junk buy a $59 (no contract) Nokia Lumia 520.
Now, turn it off by double tap. They can't because the Knock Knock off is not done the same way. So, Only half of the feature can be replicated.
Spoiler as seen here at the bottom of my screenshot, it's been done and i have it set this way. this however is for knock knock off on status bar though... and it's the way i prefer. otherwise i'd go the kernel route listed here in the faq. i choose not to because of (though very little) battery drain and i have my launcher using the same gesture for something else.
samsung's first tizen os device due before end of year. waiting for pizza_da_hut and svpernaut to comment on "dynamic boxes". :grin:
Like others have said, there are some custom ROMs that offer this functionality. Cyanogen is one. Kernels with sweep2wake usually have sweep2sleep as well - you just slide your finger across the bottom of the screen in the opposite direction to turn the screen off. TouchControl has this too. But I just came across this new Xposed module that does the statusbar knock off. You can add it to any rom if you're rooted and have the Xposed framework installed.
Yes....i'm know about sweep2wake, etc. Used it on an HTC One. Double Tap on the task bar is ok...i guess. I just like how on the stock LG G2 you can do it anywhere. Rooted Stock with Xposed Framework is what I run at the moment.

I believe it will come to both Windows 8 and Xbox One. No reason not to seeing as they all share the same kernel. Porting to the other platforms would be trivial.
Here is a full list of all known Windows Phone 8.1 features and updates. This list can and probably will change... some really exciting things though. http://www.wpcentral.com/windows-phone-81-features
Really thinking of buying a windows phone. Can you run separate apps on two separate windows like the android phones? At the stores they always push that as a big advantage.
Like split screen apps? Not at this time, but that is coming as Windows Phone merges with Windows 8 RT over the coming months/year. I'd bet in the next major update split screening like with Windows 8 will be part of it (example). You can have multiple apps open at the same time, and they run in the background (and get "toast" notifications if you allow them) or "tombstone" which is basically puts them in a saved state for quick relaunching where you left off. Just hold the back button and you can swap from open apps. iOS actually copied how Windows Phone handles multi-tasking/app switching, so if you've used an iPhone recently it works pretty much the same.
8.1 will give the developers the ability to update live tiles every 60 seconds, and a large live tile. So that will be like a poor man's multitasking,
