CM12 app install/reboot issue
I'm writing this here because I am unable to comment.


You could try a clean install i.e. wipe system, data, cache
partitions and flash ROM &amp; GApps packages.
OpenGApps recommends that you flash OpenGApps package right after you
flash the ROM without any reboots in between

know this is for 6.0 but it might be applicable to previous versions
as well)
You could try posting your logs in the OpenGApps XDA Forum link given on
their FAQ page
