In terms of aesthetics, UI, UX and functionality, it is hard to imagine what more one can expect from a phone.
In addition, the form factor is ideal for convenience of carrying and usage, with a large enough screen for comfortable e-mails, surfing and reading or writing. The primary purpose of reliable communications is also fully met by the two 4G SIM Slots. Signal reception is as good as it gets. Built-in MS Office is a truly welcome addition for all of us who need to work on the run, and of course, there are Maps and Navigation and a collection of other useful apps.
The cameras are more than good enough and offer good levels of control via the app interface(tryMode > Pro for those who are used to DSLRs. InAuto Mode, a tap on the screen tells the camera which part of the frame to expose correctly for - very useful. If one takes the basic precaution of turning off unnecessary background processes and keeping screen brightness low when indoors(as well as optimizing battery usage via the comprehensive battery settings), the phone will keep running for at least two days of heavy talk-time without recharge. It also recharges rapidly. Never tried Gaming on any of my phones, so cant comment on that, but operation in everything else is silky smooth and fast. Sound quality is good and in-call volume excellent. All in all, a virtually perfect phone.
