So, I own the Nexus 4 and I had installed Google Now launcher over the stock launcher and the transparency was just fine. Today, I decided to switch to Action Launcher and imported the Google Now Launcher settings. It asked me again, to which Google Launcher was not present. So, I selected stock. Now, the problem is, my status bar remains transparent, which is how I like it, but the navigation bar is black. On all launchers. I tried rebooting, uninstalling and reinstalling Google Now Launcher, uninstalling Action Launcher, but no success. However when I swipe to Google Now from the Google Now launcher, it shows me a transparent navigation bar, but not on the home screen or lockscreen when using Google now launcher. What can I do?
