I know this will go against the majority, but I swapped my iphone 5C for a Samsung S6 a few weeks ago, cos Vodafone offered me a boss deal.......and its the biggest mistake I've made so far, I hate the bloody thing.
Battery life is awful, I have the screen turned right down, a black wallpaper, close all my apps, yet still charge it twice a day.
Constantly freezes when moving between apps, too senstive when playing something Deezer, I only have to brush the side of the phone and it skips a song.
Had murder with Vodafone and Apple as well because the S6 wouldnt accept imessages or change them into a traditional text - the advice from Vodafone? Text everyone I know who has an iphone and tell them I dont have one no more!
I'm stuck with it now for 24 months, the only good thing I can say is the camera is decent.
