We have reported earlier in the week that Xposed Framework is here for Lollipop Touchwiz. The current install method for Xposed had been pretty complicated, but there is now a flashable zip which can be flashed in the custom recovery of your choice. I have not tested flashing this with flashfire on the Galaxy S6 or Galaxy S6 Edge. It is tested and known to work with the Galaxy S4, Note 3, and Galaxy S5. Developer "Arter97" who put this together has mentioned that some users have had issue flashing this with TWRP. He suggest using CWM Recovery or PhilZ Touch Recovery. It is also highly recommended that you be sure to make a backup in case something goes wrong with the install and you need to restore your device. Head to the link below for the download.
