I work for a phone network, up to now ive heard only good things apart from one person who come in with a battery problem, sonething to do with the fast charge function just shorted out the battery and fucked it up. But thats one person in about 300 sold so its not a bad problem

s6 edge and the s6 are exactly the same phones, the only difference is the curve.
If you want to get technical on the specs here they are.
Android OS, v5.0.2 (Lollipop)
Chipset. Exynos 7420
CPU . Quad-core 1.5 GHz Cortex-A53 & Quad-core 2.1 GHz Cortex-A57 - so its stupid fast. Its called an octicore (two quad core working together)
GPU . Mali-T760MP8
Camera 16MP on back 5MP front facing. opens from lock in 0.7 seconds - takes a picture in 0.3 seconds.
Fast charge function - 10 mins charge will last 4 hours. 2 if youre watching hd videos.
Super amoled display 16million colours for amazing display quality.
Another good point is that the wireless charging is compatable with most of the wireless charging pads on the market. Not just samsung versions of charging pads.
