I just traded my iPhone 6+ 128G for an iPhone 7+ 128G yesterday. I was aware of the JetSamEvents and my phone would frequently list them but usually just a couple dozen and I never had any issues with it. I have read where others have had major problems that seem to be linked to JetSamEvents in the log.
I had updated the 6+ to iOS 10 with no problems and I would have kept the phone except my carrier made it actually cheaper to trade it in. And it lowered my monthly bill.
My apple watch was paired to it and they worked well together. I wish I had some insight to offer but my 6+ performed flawlessly. I never had to fully restore it or even reset all settings. I kept it in a minimally protective case and it was never dropped or sat on.
I did have the camera replaced when there was a recall on it. I had noticed a bit of blurring on some photos so I took it to an apple store and they replaced the camera in about an hour. I shot pictures and videos on it that looked good.
In my opinion - for what it is worth - I would have it replaced or upgrade. So far my iPhone 7+ is working great. I have shot some video and have been pleasantly impressed. If it performs as well as my 6+ I will be very pleased.
