Well I've been using it for about a week now and I've not really had any significant signal issues. The signal does drop a bar or two when the bottom left corner is completely covered, but I realistically never hold my phone in that way and it's a trivial thing to avoid.
I think the phone is otherwise superb in every way. It's my first iPhone and the first one I've ever felt truly ticks every box you could want from a smartphone. If nothing else bus journeys are so much better being able to check emails, read MapCore, etc. ![]()
The touch-to-focus feature on the camera is particularly nifty. Would be nice to see that appear on more cameras/phones.
