After a week of use as daily driver:
1. Battery compared to the stock 5.01 is better (probably around 20-30%). I suspect it is due to the less bloatware running in the background.
2. Camera app seems slower (mainly startup).
3. Not a big Phone ...
Request for stk1160 easycap drivers (this kk kernel has them - http://forum.xda-developers.com/showthread.php?t=2558717) and OTG charging (for car installation).
Thanks for your time/effort.
