So i decided to use snap chat again and installed on my rooted 6p, knowing that i couldn't login with the safety net shiz, i unrooted, re installs snap chat, logged in the re rooted and its works as you'd have expected it. Apart from its super laggy, slow and delayed. when taking a snap vid its literally 10 fps.
wondering if anyone knows of a fix part or long term ??
Note: Stock rom, system runs fine with loads of free overhead so it not like its getting bogged down.
