This mobile is pretty same like asus zenfone 2. It has intel atom Z3580 3.3 GHz cpu whis is good and has a 4GB ram, so its actually pushes in terms of ram.
It is one of the devices which can play 4K videos flawlessly. Maximum volume is decent and it has heating issue when you are doing heavy tasks like benchmarks or something but not as much as any others but it would. It is very good for gaming. It has rear 13MP and back 5MP camera which is above average in terms of its quality. So, I recommended you to buy this phone.
