[HELP] unrooted phone without uninstalling xPosed

Hi, I have a Wiko Highway that I want to send to warranty.

So i had my phone rooted, and unrooted it and then factory reseted it, but i forgot to uninstall xPosed and its modules.
Now i started to install some apps so i dont send the phone empty, and when installing snapchat it wont let me login (as it block's rooted phones)
So, by some way snapchat "thinks" i'm still rooted, i'm afraid the provider can tell that :/

Is there anyway to prevent this?

Thanks

Unrooted After Factory Reset - Samsung Galaxy S5 Mini

I rooted my G800F using the Chainfire Odin Pack.
Then I factory reseted my phone and then the root was gone.
I still got the SuperSU app installed but root wasnt working.
I used root checker to test it.
I know that i can flash the stock firmware but i really want to do that only if nothing else works.
Thanks for answers.
