One of the best launchers out there. Works great on both new and old hardware. If you have four years old cellphone or a new pricey tablet, Nova Launcher is going to work fast and flawless for you.
Nova Launcher is highly customized. You can change the interface with themes and icon packs. The good news is that there are a lot of themes for Nova Launcher in the play store. You can install and then activate them just by going to Nova Settings.
I usually try to point out problems based on my own experiences but honestly, I can’t think of any bug or problem in Nova Launcher.Enjoy!
