I've had my iPhone 4S for a few years now and I've decided it's time for a change. The battery has become terrible, the phone randomly turns off even though I have a lot of battery and sometimes the touchscreen doesn't work when trying to receive calls.
I'm thinking of switching to Android because I'm getting bored of iOS. Right now I'm looking at the Samsung Galaxy S5, the HTC One M8 and the Sony Xperia Z2. Not entirely sure which one I want. Anyone got any experiences they would like to share? I've also heard good things about the Nokia Lumia, so it doesn't necessarily have to be Android.
Basically what I'm wondering is if you're a smartphone user, which phone do you use and why should I buy that one?
