The build quality of phone is great.The full metal design with front and back having gorilla glass 4 gives a premium feel.It might be difficult to hold easily, it is so slippery.
The performance of the phone is great with no lag in multi-tasking.
Front and rear camera is best with good image processing.
The big drawback is the lack of expandable storage and the battery.
Battery will not last more than 6-8hr on continuous usage and need continuous charging.On normal usage it will last for 13-14hr.
It is a great phone with good value for money.
Sound quality is great and and speaker is excellent.The in-ear phone provided is of very good build quality and produces nice sound.
