When my sister asked me to buy a smart phone, then immediately I suggest her to buy this model because previously a friend of mine also bought this model of product and was running excellent. it has various features that you are looking for. My sister is happy to using this since one year
# Android 6 marshmallow os with Octa core processor, having 3GB RAM, 32GB ROM and you need not buy any extra sd card because you have already too much storage, though if you want to buy extra sd card then you can expand it upto 128GB, supporting USB OTG. There is 5.5 inch full HD display where you can watch videos, movies and play games bigger screen in 1920×1080 pixels resolution and sound quality is wao. You will be surprised to see its 13MP rear and 5MP front camera, with this you can capture all those beautiful moment in your mobile. It has also power ful battery of 4100mAh battery li-polymer where you will find that the best battery backup. Because I think if you buy any smart phone which have no long lasting battery than its valueless.
Apart from these It is very light weight and thin. Due to its thin and slimit looks stylish and attractive.
