Can't install paid apps, and system ui crashes
Alright, so I'm having a few problems. I am using ARHD 30.0, and went to install Nova Launcher and Nova Launcher Prime. Nova Launcher installed fine, but Prime did not. I then tried to install XDA Premium, but it failed also. Both of the paid apps fail with the error "Couldn't install to SD Card, or internal storage." Or something like that.
For the System UI Crash, I used Sense 5 Toolbox to change the app switcher to AOSP Style, and now, after closing all apps, it says System UI has crashed. Oh, and it also says the gapps process has stopped whenever I boot. What is wrong with my phone?
