I have heard horror stories about upgrading to lollipop so I DO NOT want to upgrade but I keep getting constant notifications to upgrade. How can I shut them off?
Root the ROM that's in the phone, then freeze the updater app if you want to stop seeing the notices. (Rooting will keep the phone trying to update and failing [without harming the phone - the update just gives you a fail notice and quits when it finds itself in a rooted phone]. Freezing the updater will keep it from even trying to update.)
