Great work, and no need to apologize, your English is fine!
Unfortunately, I have been unable to conclusively reproduce your findings. I've concentrated on the notification panel memory consumption because it also happens in CM and it's something...
Alternatively you can have Tasker force manual sync, at the exact time and intervals you desire. If coincided with Google sync, it is much more efficient and energy saving.
I vote for temp removal of Pdroid for now
I build a RR ROM for 925 S-K-L devices, if someone wants to try it. I'm not sure if it'll flash in F devices... fell free to try.
RR 925 S-K-L
Does your rom work with 925i ?
Much thanks for sharing...
Not sure if I can post this question here, but what method did you use to root your Note 3?
