I'm trying to remember what they had over the S7 Edge. They refined the edges of the edge, lol, and moved to Gorilla Glass 5, and refined TouchWiz. I think the culprit could have been making the move to USB-C combined with whatever went wrong with their battery supplier's batch of batteries. I've read so much speculation and a lot of it sounds like it could have happened to any manufacturers. No hard facts yet.
I've read talk over on an Android forum that there was an article about how the delays in getting significant shipments of IPhone 7's out was due to faulty components. Then someone else had a link to an article that quoted someone saying the same manufacturer of the exploding batteries, a Samsung company, also supplied Apple with batteries for the IPhone 7. Who knows...there's so much idle gossip and speculation going on, that's why I hate to see it taking place on an official article on this forum.
Especially that whole Jeep incident is very dodgy according to people who looked into the family and their social media posts.
I'm not trying to be an apologist for Samsung just because I had bought a Note 7. In fact just yesterday my Galaxy S7 burned me on the leg, as I posted on the non IOS portion of the forum. That danged thing runs hot a lot. This time it was likely my user error, overlooking the flashlight being on. But sometimes it runs hotter than I'm used to a phone running when it's not being set up or running an intensive game. Do. Not. Approve.
I just want unbiased and accurate discussion and reporting. Well, as much as we can get of that on a fan-based site.
