I've already done that. I actually installed an older snapchat online (2.1), this is the one I used to have and was working fine, I installed it on my phone. But now its glitchy and only records 1 video after I restart my phone. I have to restart my phone everytime i want to take 1 snapchat video then snapchat force closes.
I'm starting to think I just have to wait till Snapchat fixes the bugs on Android. Everything seems to work fine for iPhones. Come on snapchat!
