One of the great things about Android is the level of customization you can bring to your device, personalizing just about every single detail if you wish. One of the easiest ways to personalize your phone though if you want to keep things rather simple is with wallpapers. If you enjoy some of the style that comes along with Android Lollipop but may not yet have that version of software on your device, you can at least make your device somewhat look the part by applying wallpapers that were created based on the looks and style of material design, which is the design guidelines for Android Lollipop.
There are more than a few apps out there that can help you with this, and Walloid is one of those apps. Not only does it have a material design look to the UI of the app itself, but it features tons of material design inspired wallpapers. With over 3,000 different wallpapers, many of them styled with material design like elements, you'll always have a new fresh wallpaper for your device and could even switch things out every single day of the week if you like. The wallpapers are even updated daily so there will always be more coming in, ever expanding the library of wallpapers in your collection.
The Walloid app has a favorites section so you can browse through what's available and pick and choose the ones you like the most, separate them into favorites, and cycle through what you feel are the very best wallpapers that Walloid has to offer. There are also multiple categories so searching for the perfect wallpapers is as easy as can be, with categories like HD wallpapers, downloaded wallpapers, and even wallpapers featured in stock and custom ROMs. Like knowing when new things are added? Walloid has notification support so you are alerted to newly added wallpapers as they come in. If you like things random, there is even a random wallpaper widget which will select a random wallpaper and apply it for you, and if you want to get rid of the ads in the free version of the application there is a paid version available which comes completely ad-free.
