The only real benefit i have with the upgrade from iPhone 5 was the better battery.....i was temped by the touch id and now i have regret it.... 1) I ve added my thumb with all touch id available registries and while it works PERFECTLY in the beginning after a while i get the annoying TRY AGAIN TRY AGAIN .... my fingers are always clean and i ve register my thumb by moving around it a little bit while scanning.... as the constructions say... whats going on?... is it cause of cold weather?.... Touch id is f.... gimmick till now. Cant manage to make it work more than 50% the time..... and why some people say that it learns from your errors and you shouldn't delete it..... 2) While on my iphone 5 the gps locked almost instantly (around 10-30 secs) on my iphone 5S it needs around 2-3 minutes to lock.... same happens at apple maps not only while using navigon... i also got poor reception while using navigon....i am wondering if that is mostly ios 7 problem and not my iphone 5s.... ps - i also hope sometime Apple will finally fix iphones main disadvantage over other smartphones... which is low speaker volume! Help me or i am going back to 5... or probably to 5C!
