let me prefix .... I'm a middle aged woman .... I love my Droid Ultra .... I love Active Display .... I LOVE the speakers. music sounds great .... I love the SIZE (don't want anything larger) BUT my screen is cracked .... at the bottom of screen, only my back button works ... home button and multi page button hasn't worked on over a year. should I just have it fixed? or upgrade? I considered Galaxy S5/ S6 .... or HTC 8/9 Any suggestions?
