I posted this in another community where I'm a member off, as the same question was posed there. I have been waiting for this possible phone release myself since August
This "rumor" was released into the world in August very shortly after the Note 5 was released, with the only mentioned possible change it being a 4100mAh battery. Many sites picked this up and spread stories about this, but nothing new since August.
I have been checking with my local AT&T store, since the release was rumored for this week, but they have no news yet. I e-mailed the author of the article and his director, to see if they had updated information from their source, and no reply as of yet. Not that I was expecting one necessarily, but I figured why not try.
I have also tried a few chat sessions with AT&T and have been told and it was confirmed multiple times by two different people that this is indeed happening. I was also told that it would have a 4100mAh battery indeed and that the person was told it would be kinda huge. But that is all I know. No specs, no details on whether it would possibly be crippled like the S6 active with only a 32GB version; and no details on a possible date.
I'll copy the reply here to my question if the person I spoke earlier to this week did indeed have correct info and if this phone would be released:
"As I checked here about that phone, yes you are correct. But for now, here in AT&T we are not yet updated about the release date of this phone, but rest assured that we will release this phone and we will give you a feedback once this is release and when you can order one."
So that is all I know. Does anybody around here know anything more? With such a battery and with Samsung moving away from SD support, I just hope they don't release a 32Gb version only. Memory is so cheap where even 64 does not really make much more sense any longer. All these phone with huge specs should be 128GB, and nobody would whine about SD support. I'm not really worried about replaceable battery, since I have a large Jockery device that I can use if I get low, but at 4100mAh, getting low would require heavy use.
