Some of this has probably already been posted by other users. But here is some issues Ive experienced. iOS 8 has been the most Glitchy update Ive ever used. Ive been using iOS since the iPhone 3G. This iPhone 6 feels like its not fully baked. Its reminding me of the windows Vista launch. Here is a list of my issues and my solutions: iPad Air with iOS 8.0.2 on it: While browsing using safari the whole Springboard crashed. Usually safari would crash. But the whole OS crashed. Just from browsing basic websites. This happens multiple times a day. This happened on 8.0 and 8.0.2 I also have an iPhone 6 64GB: Weak signal strength compared to iPhone 5 and 5S. iOS 8.0.2 made it worse. So I had to downgrade to 8.0 . Youd think with the thick antenna bands this phone would have awesome reception. Not the case. Toggling airplane mode on and the off helps with the weak signal problem. one of the issues with 8.0 is the wifi isn't reliable. Sometimes it doesn't find ANY routers to connect to. It will just keep searching. The only thing that will fix this is to turn the phone off and then back on. Phone sometimes doesn't respond to being in landscape orientation. This happens sometimes. Oh and I just tried to open the Phone app and the whole OS froze. I had to hard reset it to get it to turn off. This is seriously the buggyest phone Ive ever purchased from apple. I cant believe I waited in line for this. I really hope they make these bug fixes a priority over apple pay. That is just something I personally wont use.
