Wasn't the problem that was found with the burning ("exploding") Samsung S7 Note the fact that they made it too thin without enough space for the battery? Did they not learn their lesson?
Also, I want a headphone jack. I love my headphone jack on my Samsung S7 active. I can plug many things into it, many things I already own. It's flexible, compatible, a great thing. I don't want a super thin phone. I just want a fast, reliable, convenient, water-proof phone that has flexible and standard connectivity with a battery that can get me through 24 hours of heavy use without needing to charge all the time. I'll pay money for that, not for some fragile, super-thin device that needs to be charged all the time.
