I find that my battery depletes rapidly when it hits the 70% mark. I've also come across alot of bluetooth issues. i.e streaming to my Bose SoundLink Mini. It becomes increasingly hot when using applications such as: Clash of Clans & Facebook. This isnt as regular amount of heat, it gets to the point where i have to stop and pull apart the phone to manually cool the battery and body of the phone. It also has an issue where by if i have WiFi turned on, it blocks all communication with my cellular data. I was able to counter this by simply turning it off. Though with the already known issue of GPS, this isn't really a viable option. I absolutley love the overall feel of the ROM and i would love to have these issues fixed so i can use this phone and software as my daily driver. All the issues highlighted above are issues i did not run into when using my previous ROM which was a nightly cm11 build. Please Update and fix so i can recommend!

Download the Latest SuperSU file from the below link and flash it through recovery:

I think you might not have done the Data wipe or factory reset while upgrading the ROM.
If you have done so and still you face this kin of problem then I would like to request you to do that again and then re-flash the ROM.

Before flashing it again make sure that you have a backup of your precious data.

Hi,

Having the same issue as Daniel i.e no keyboard. Running CWM 6.0.4.7 wipe data/factory reset, wipe dalvik cache and wipe cache partition. Have updated to latest version of SU and installed Gapps 5xx
