[10 Oct. 2016] UPDATE!
Okay! Finally some happy news for all you guys. A tool called SnapRestore is able to recover messages upto 3 months older without providing our login details! So ignore following older unreliable methods and try SnapRestore from Here. Hope it helps 🙂
Due to the nature of their website, normally a deleted Snapchat message or a photo is unrecoverable in most cases. But if you viewed it at least once on your mobile device, there is a chance of recovering them. What you have to do is just go to appstore or play store if you’re using an android device and download a snapchat restore app. Some advanced apps allow you to recover expired non-viewed photos too. Let’s take a look at some of these apps…
