Xiaomi created and excellent gadget.My prime requirement of mobile phone was internal storage and battery life. both these purposes are well served by Mi A1.The big screen is awesome for gaming, video, social media and reading. The resolution is also great. SD625 processor along with 4GB RAM and 64GB storage is an excellent combination which provides great performance for gaming as well as productivity purposes. I usually play casual games, but it can handle most of the high end games without hassle.
