The general consensus is that you need to find the default app in application manager and click "clear defaults" (Dzwonki Samsung darmowe). However, the app I accidentally choose to use always is Verizon Cloud. I am not signed up for it (every time I click "choose sound from device" It opens up Verizon cloud'storage Get Started page), and I can't find it at all in application manager. How can I change this?
