As you all know, snapchat does not work on rooted phones anymore... Wrong! It doesn't work on phones with xposed framework, at least upon logging in.
steps (modified and simplified)
a. uninstall xposed framework (ROOT DOES NOT MATTER, HAVING THE XPOSED APP ALSO DOES NOT MATTER, MAKE SURE YOU DO NOT HAVE THE FRAMEWORK INSTALLED) before installing snapchat then do a fresh install of snapchat. Only disabling the xposed module=fail
b. log in into snapchat whithout having the xposed framework installed.
c. after logging in, install the framework back
voila, now you have all the xposed functions plus snapchat working just fine
