Still waiting for my S5 to get Marshmallow via AT&T. I know, fat chance at this point. lol. I have a verizon phone for work too. No comparison how other networks push out their updates compared to AT&T. Ironically, I just received another software update from AT&T about 20 mins ago. Hopes were raised thinking it was Marshmallow. Nope, just another 206 mb security update, I guess for June. Long story short, I have 2 months left and I am no longer remaining an AT&T customer. 15+ years, never missed one bill and I will be gladly walking away. Like anyone else, I want the newest software. Its a big kick in the balls when literally every other carrier offers the update except the one I am on. Oh well.....
