You asked You have it. Apparently Samsung knew already what will be the customers reactions about the recent presented in March 1st Galaxy S6 and Galaxy S6 Edge that don`t have a removable battery, additional storage with a micro SD card and a waterproof protection. Well all those features are going to be available on the Galaxy S6 Active.
Additionally the Galaxy S6 Active ( SM-G890A ) will sport a much larger 3500mAh battery instead the 2550mAh battery in the Galaxy S6.
The Galaxy S6 Active (SM-G890A) will have the same 5.1 inch QHD Super AMOLED+ display that the ‘regular’ version of the Galaxy S6 features. Besides that, the device will feature pretty much the same set of specifications as the Galaxy S6 itself, including the Exynos 7420 SoC, 3GB of RAM, 32GB of on-board storage and a 16-megapixel / 5-megapixel camera combo. What will change though, are the dimensions (but obvious), which will now read 73.6 x 146.9 x 8.8 mm (as opposed to 70.5 x 143.4 x 6.8 mm of the Galaxy S6), and the battery size, which will be upgraded to 3500mAh.
As the model number (SM-G890A) states, the phone will show up first on AT&T networks.
