Well after all the issues I have had with three phones from Samsung and now on my 4th, I call this Karma. That being said, even though I was an iPhone guy prior, even they are having issues right now sourcing memory. So I would assume that Fruit is going be having problems if they don't get their QA process resolved.
The reason this happened with Samsung is they were trying to push the sales prior to Apple. Nothing more than greed.. and now they are paying the price for it. There are more than battery issues on the Note 7 (all be it) varied by carrier and user. ie. my case... bad reception, a notification sound that loops it self like a DJ is scratching a remix of it (only shut off by waiting 5/10 seconds or hitting power), and now where the contacts won't all come over and the I have the LAG. (Which I did not have on the prior three devices). I am tired of being the beta tester for TMO and Samsung. They should have tested this phone more throughly IMO before releasing this device to the masses.
