I'm looking to sideload the sms app that i've had with two previous android phones. After getting my new N5 yesterday, it seems the stock 'messaging' app has been replaced in favor of hangouts. New to hangouts, but after about a day, i can say f-that. I know other sms apps are out there, but i really just want the one I've had for years. I promise I've used the search feature, please don't fault me if this info is out there.
