We've tested this method and it works just fine as of Thursday afternoon, although there's a good chance that these steps won't work for very long and you'll be stuck with the updated version. When reached for comment via email, a Snapchat spokesperson told Thrillist: "Updates as big as this one can take a little getting used to, but we hope the community will enjoy it once they settle in." In other words, this redesign is probably here to stay.
How to turn off automatic updates for Snapchat
1. Go to Settings > iTunes & App Stores > then make sure the switch next to Updates under the list of Automatic Downloads is set to off.
2. Never update your app ever. You'll miss out on any new features, but you'll also never age, stay in college forever, and your friends will never get married and stop hanging out with you.
