none of the apps in the droid life link u posted are fully working. ive tested them the only things that do fully work in those links are the google play services and hangouts.
keyboard is buggy but works.
camera works but no photo sphere.
google home is buggie and yes i installed this with play services and google search i even removed the original play services and search and installed these to system still no go. google search force closes when u try to use the voice search it will recognize what your saying but as soon as it goes to search force close.
havnt tried gmail, gallery, email, clock, or calender.
useful if only they all worked if you figure anything out to get things working let us know. but u def just gave me something to play with tonight. will let you all know if gmail, gallery, email, clock, or calender work by tomorrow.
