lock screen widgets for your Android handset, unlike 4.2 Jelly Bean, which introduced them on by default. In KitKat these are buried under a settings option that is found in the Security menu, and that's not for all phones and overlays even.Android 4.4 KitKat made it somewhat more difficult to enable
Furthermore, even if your Android dons the ability to place widgets on your lockscreen, you can only place one at a time, even if you have a phone with a huge display that can fit much more comfortably, thus letting you interact with your most used apps without even entering the main interface. When there's a will, there's a way, though, so how's this for a surprise - there's a simple mod now that lets you place up to four active widgets on your Android lock screen, and it doesn't even require root, Xposed modules, and all the usual paraphernalia, working on most devices out there. Here's what you need to do to host them four widgets up there:
2. Fire it up and choose whether you want the app to run in the background, i.e. be active, and how big do you want its launch pad on the lock screen to be;
3. The next step is to actually add the one to four widgets in the four quadrants of the screen, which is easy and very interactive - you just tap on a quadrant, and pick a widget to your desire from the list;
4. Lock your phone, and when you unlock the screen, tap on the lower left corner where the Widget Pager launch pad is, and all four widgets will pop up for your viewing pleasure.
This initial version of the mod allows only up to four widgets, and on one page only, but for the future the developer promises a Pro version which will let you put more, and slide between pages full of them directly on the lock screen, good stuff.
