First of all the built quality is awesome which features an incredible design.Even though the body is made of metal, the sides of the phone is made of plastic.The sound system( dolby) is simply phenomenal compared to other phones mid range segment of the smartphone.Even though the company has not specified it does not feature quick charge, it charges very quickly like 0-100 in 1 and a half hours.The performance is very good as it features 3gb ram where 1 gb ram is always left vacant.Overall the phone is very good and worth every penny.
