I’ve been using s7 edge since last month, so far have not come across any issue. It’s a dual Sim with a very good battery performance.
I’ve recently shifted from iPhon brand to Samsung. However, there can be no denying the fact that IOS is more user friendly thand android.I used iPhone 6s, the only thing that attracted me the dual sim feature in such a high end cell phone which is a huge advantage.
If same is offered by iPhone in the upcoming launch of 7 series it will sweep the market. But it looks to me a remote possibility as it wud entail to make a bit thicker body of iphone to accommodate the bigger battery. All in all Galaxy s7 edge is a competitive cell phone to deserve ur handpick.
