Just bought new Nuxus 7 II (2013) for use with P3P (from Groupon). Any advice? Should I upgrade ROM if there is software update available? Does the new update cause problems? Or will the tablet already come loaded with the newest operating system? if so, is there way to wipe it and revert back to original Operating system? (I heard about problems from newest ROM updates?) I tried signing up for HTC account on my HTC one M7 and it will NOT let me even sign up for an account? So I tried a ROM update (may have been mistake?) And still would not let me. Then I tried Nexus 7 (1st gen) and it says "not compatible" I heard there is a workaround, but sounds complicated and maybe not reliable, so that is why I purchased Nexus 7 II (2013) Also tried Samsung galaxy 3 and could not sign up for DJI Go app (Although I did not think this phone would work) Any advice on the Nexus 7 II 2013 would be appreciated.
