"Remember iOS 7 only gave panorama shots to the newest iPhones."
thats funny, my 4S takes panoramas just fine, and it wasn't new when they introduced panoramas. Heading for 3 years old now and still working just fine. I love it and love the size.
I would really be slow to have to go to anything bigger than the 5, screen wise, but the battery on them is so bad. No-one i know has good better life.
i really have to start investigating this on herself's phone,...
