ERROR: Removing the SD every moment with Lollipop

Update my S5 SM-G900H with lollipop Kanzakhstan version 5.0 which has worked well for me but not quite as each time you unlock the phone I get a message that assures me that the top of the battery is well placed, this Following a failure of the SD and that at times it is removed and remounted the SD.

I wonder if someone feels the pampering and how I can solve it ???

Removing a strange IP address, how..

Nexus 5 android 5.1.1. I noticed it a while back and thought flashing the newest factory image would take care of it but it didn't. I'm assuming there is a block on it of some sort, I have no idea how it got on here. Haven't gotten into writing code but I think I should. This is troublesome and any help will be much appreciated. I'll include a screen shot also. Thanks
