People, For anyone who hasn't the time to review the whole thread: Good news! It seems that iOS 10.1 public beta 3 solves the signal problems with affect the Verizon (and Sprint? + other CDMA?) iPhone 7.
Thank you to everyone who’s related experience with the 10.1 PB3. It sounds promising.
There’s so much frustration in this forum! If you have an Apple Watch, try using the Breath app. If not, just set a timer for 2 or 3 min, and breath.
Like many here, I'm upset by the signal problem with the iPhone 7. But ranting here won't solve anything, especially as some of the comments come from very poor or incorrect information. Additionally, Apple doesn't typically respond here; thinking that shouting will improve the chances is silly. The situation is very complicated. So much so that Apple and Verizon (and others) weren't yet able to correct this -- even now. If you think they aren't trying to fix this, then you should count yourself among the mis-informed.
Mr Toningon3, your assessment that fault lies with iPhone 7 hardware is not likely correct. The iOS 10 running on your 6s is different from the build on the iPhone 7. Each type of device has different components from RAM to CPU to radios. The radios chipsets in the iPhone 7 are not the same as the 6s or 6 or SE. The code they run is different. Maybe a little different, maybe a lot. Hard to say.
Regarding signal strength, I don't know what reviews you're talking about. My iPhone 7, sitting next to my iPhone 6, "sees" more radio signal as measured by the field test display. Advantage iPhone 7. So hooray!
It’s possible there’s an issue with some component in the iPhone 7, but not likely a defect. New software will either fix the bug, or work around a hardware “issue” so that things work as they should. If I were to guess, I’d be looking at the new radio chipsets in the iPhone 7 (Qualcom modems perhaps?), and the code that runs them.
PS: For anyone still feeling annoyed, I contacted Verizon and complained about the signal problems on my new iPhone and got a credit to my bill; this makes up for the ludicrous “activation fee” they now charge.
