I recently used these phone , it was quite good in my hand, but with bigger screen.
When comimg to phone , the Ram performace is excellent having great 6 gb Ram with a powerful Snapdragon 821 processor .
The Design of the phone is good for feel which is made of aluminium .
The slow motion camera affect is good , I liked the their Oxygen OS .
Recently these has got Oxygen Os update 4.1.2 , that was quite awesome.
At very Rare times there will be some Fingerprint issues on these phone , but it was cleared with that update
switching of apps is super sexy in these phone
Lastly, I can say it was a good mobile for every user even for Gamer.
