I have had my iPhone 6 64 for 1 week tomorrow. Very happy with the phone. Had ipone 5 before. I cannot search my text messages on iphone6? I type in the search area, select search nothing happens! Any one have this issue?
I was having the exact same issue on my iPhone 5s after upgrading to iOS 8. I recommend switching the language on the phone and then switching it back. While this seems extreme, it worked and now I can search my messages again. I suspect this has something to do with a database cache that is forced to reset in the language switch, but whatever it is it worked for me. Best of luck!
