Loving the phone. There are frequent updates for the OS which are making it better. Snapdragon 810 is a chip-set which runs warm not HOT as others claim.
The camera quality is also superb. The audio output via speakers is a bit on the low side but the output via the headphone jack is superb. The phone feels light and ergonomic, plus the sandstone back is awesome.I would recommend this phone to anyone who has the budget and an invite(of course) to buy one. This is one phone which gets close to Samsung galaxy s6 and iphone 6 in true sense and almost at the half of their price.
