                       first let me start with the design. though it has 5.5 inch display the built quality has changed considerably now its enclosed in something called magnesium metal alloy its gives us a very good premium feel in hands. but the con is that weight distribution is not great.though it has only 175 grams in weght but it feels heavy but not too heavy its little a bit uncomfortable to hold. in addition we have a great 13 Megapixel rear camera with laser autofocus,Awesome fingerprint scanner and the alert slider is very handy to use.
                 This device is powered by the 1.8 Ghz snapdragon 810(64 bit)  octocore processor divided into two quadcores first high perfomance quadcore is based on ARM cortex a57 architecture and the another quadvore is based on ARM Cortex A53 architecture.
