Okay, here's my 10 cents. I would like the google camera to work on this phone. Google's added it to the playstore but it is kitkat only. Second, there seems to be a problem. Third party keyboards do not work. It is a pain to enable them and they mess up the settings. Lastly, I can't enable the nav bar. I have tried but no cigar, doesn't work. Instead it toggles the overflow menu when you change the build prop line.
These are things I have noticed and I'm not sure what is causing the problem, at least for the last two :/
