Standard issue response. GF is an attorney, i studied it and ended up in advertising; thats standard issue to acknowledge there are customer complaints and they have been passed on. Dont expect anything proactive from att or samsung.
problems are sporadic and random; based on sales volume samsung projected about average for issues with most tech products. most are about screen scratching (well its plastic; put a glass cover on it and problem solved). if yours works, dont worry about it. CR testing was massively flawed scientifically, and they also beat the thing up BEFORE water testing it. frankly after their methodology i wouldnt trust a CR review to be scientific in any manner whatsoever, even though its probably somewhat realistic. ive put mine thru hell already, cousin took hers swimming in the Aegean sea to take pics, gf dropped hers in the bath, zero issues. heck i even charged mine (wirelessly) in a walk in cooler and in a freezer after getting it nice and wet to see how it held up to high temp battery, cold temp outside to promote condensation etc. zero issues.
also, CR has had some issues with regards to wildly fluctuating reviews of (cars in this case) that had the EXACT SAME parts (engine/trans etc) only difference was model year tested, and all other reports including dealership/mfgr complaints were statistically the same as well. Consumer reports is IMO unreliable as they never retest nor do they test scientifically at all; totally subjective, same with a LOT of 'reviews' etc.
there are always bad examples of anything, and stellar ones too. many people believe rotaries are unreliable, blow apex seals in 40k miles or need rebuilds at 40-60k miles... based on my experience, with 5 RX-7's (one was a turbo II 2nd gen) and 1 RX-8, totally untrue; never had a motor blow up/die slowly/lose an apex seal, and all but one had over 200k on them zero issues besides maintenance (which is far more critical than on piston engines). oh, and the takata airbag recall. the last one i still own only has 140k miles on it and still pulls like hell; its my daily driver as well, and i regularly exploit its rediculously high 9k+ redline and awesome handling characteristics regularly, and its an '04; the 'worst' year and 'least reliable' as well. ive beaten that car savagely, and taken care of it, since about 2k miles (break in period) and i drove it off the delivery truck myself with 1.8 miles on the odo. when i hit 200k ill probably sell it, or rebuild the engine because its interesting and challenging, and while it eats oil and sucks gas and im always changing oil or plugs or filters or coil packs, thats preventative maintenance on my end, and it shows as its still in factory compression spec, 12 years and 140k abusive miles later. anyways.
CR is for AARP members; no one reads their crap anymore anyways in the digital age, although, that said, i would certainly reference their test results if my S7 Active suddenly had issues. and your chat will do nothing to help IF you have issues; you would have to have a chat or two detailing issues you ARE having for it to mean anything and keep a record, and also let samsung attempt to fix/repair/make it right and STILL have that same issue again to have any legal standing for recompense, legal action, or recourse, unless you are within the 14 day carrier return period, or bought it with a credit card that offers a 30/60 day policy and then thats a whole different story.
