Which smartphone

[Exploration]

I've had Windows and Android.

One and only Windows Phone i ever had was a HTC 8S, i didn't like it to be frank. There was nothing wrong with OS per say, but it did crash from time to time and the Manufacturer i didn't prefer at all. Infact it overheated while charging (Charging it from totally drained), caused the battery to expand and shatter the glass on the screen. Not too impressed. The OS though was fine despite the responsiveness and customization.

Android, i've had these things for ages. My latest which you'll probably not have heard of this manufacturer in a while is a Motorola Moto G(as a replacement for the HTC), this thing to me is magic. Fast, smooth and it's screen is brilliant for HD. It's quite good in terms of quality. Dropped it once or twice and there's not been a scratch. Cost me around £110 brand new and it's done the trick running Android 4.4.4 Kitkat effortlessly. I'd highly reccomend Android (Samsung, Motorola and LG Phones).
