Had the phone since release now and its just unbelievable. 2 minor problems one is getting used to the increase in size from S5, the other was having to buy a cover from Samsung as found it far too slippy when using the device. The camera under low light is amazing. The phone did heat up considerably when first setting up but no issues since.
The battery lasts all day with considerable use. I listen to music all day, facebook, news, youtube etc and still have enough power in the evening for an hour on the Gear VR. Without doubt the best mobile device Ive had(including nexus devices). Still not got used to the size yet so in hindsight maybe the normal S7 would have been better for me. Highly reccommend,
