I made a factory reset because the problems I reported in other post.
Now, my P6000 is back in V0.1-20171021 version and it seems that runs better. Some old problems of my phone persist (screen not good, proximity sensor not good, and other), at momment (1 week) no random restart (touching wood I am...), but the battery is clearly more durable. With the use I make, 200180104 runs only 2 days. 20171021 runs 3 days.
I would not install 200180104 version.
If your phone, for you, works without issues, there's no need to update it
