Well I had decided to let go of my Onyx Black S7 Edge today. Phone already couriered out to the buyer
I t was a very good phone and main reason why I decided to sell it off as I feel uncomfortable using it due to  its overly compact size . I always prefer a slight larger size eg LG V10 and Mate 8
Anyway I had several phones with me now ( LG V10, Mate 8, Nexus 6P, iphone 6s+, Lumia 950 XL)  and to let go now at a reasonable good price is better than to keep it unused generally. I would just like to keep 2 Androids with me. I basically use it 2-3 hours every 2-3 days only.
I must say this is the best Samsung phone I had ever used amongst all the Galaxy and Note series. It is speedy, doesn't lag, excellent camera and decent good battery life ( I could hit 7-8 hours SOT).
My daily preference is still the LG V10 and Mate 8
