Sony xperia z5
My phone's screen got slightly smashed. I can see fine on the screen, but the screen doesn't respond when I touch it. I am not sure how it works. Can only the outer screen be replaced, or should the digitizer also be replaced? It's quite expensive. So i would rathed buy a cheaper second hand samsung for R1500 than replacing the screen for almost R2000. Please help.... i love my sony, and don't want to lose it..
