same as above, I performed factory reset (coming from MIUI 7 China dev), flashed CM> SuperSu, wipe dalvik/cache, reboot, then Gapps, wipe dalvik/cache, voila!
tho SuperSu doesn't seem required as CM comes with root.
Google Fit doesn't come with Pico right? in terms of Google apps, I installed Drive, Hangouts, Keep, Waze*, and YouTube from Play store and none had FC or required clear data or cache. *Waze was bought by Google, tho technically not a 'Gapp' per se
Camera has significantly improved since MIUI, it's finally snappy like N5, so I presume it's a software issue.
however, Bluetooth keeps dropping. noticed this from using SmartLock with bluetooth device
