Have you tried a different cable and/or wall charging plug?

If i plug in and plug out I've got different response...
Some times usb some times ac .
Is there any file on my kernel to control this?
I found a file in root directory by the name of charger . but i can't read this file!

Plug the cable into the phone first. I have the same problem with my Venue 8 7840 too.

Samsung differentiates by a pair of wires shorted in the AC charger, so if the phone sees those wired (the data wires, actually) shorted, it goes into AC charge mode. Nexus may do something similar, and the "indicator" in the charger (a short, one of the data leads grounded, something) may have become intermittent.
