I have an LG Ally, and I would call myself a new-ish smart-phone user. The phone kept nagging me to install an update, and when I finally did, it broke 3 apps, deleted a shortcut, and gave me a new app that I don't want & that requires a subscription. I've never tampered with the phone, never downloaded a non-Marketplace app. Is this the way Android usually works? If so, can I avoid upgrading altogether? Thanks!
