So, received my silver 7 this morning. No great excitement just nice to be able to double up again to the 256GB... ...and then I notice it. Surely not... Auto-brightness definitely off? *check* Nightmode definitely off? *check* Any other new weird display settings in iOS 10? * nope* Put iPhone 6 next to 7 to compare? *WTF?!* The 7 display looks significantly warmer and darker, with both on full brightness. We're talking iPhone 5 levels here. So I call my carrier to complain and ask for exchange. Put on hold for a while whilst waiting for technical support. And then I'm told "Apple have contacted us and said there's been an error with the first batches, they were left on factory settings in the diagnostic OS and this accounts for the display issue" I'm then told I can either return it to an Apple Store (umm no thanks, imagine the throng) or my local Vodafone store (who can also do the firmware fix as they've been sent the update from Apple). An exchange is fine but they couldn't guarantee a batch unit that was unaffected. I understand there's QC issues occasionally but this sounds like they rushed them out the factory to meet shipping deadlines without a fairly major final step in the process. Completely avoidable and pretty shoddy.
