iOS 7 has a number of new features and advantages. However several drawbacks and these are big ones. One of them is the phone and for some reason the buttons are twice as small as the phone in iOS 6, and the delete key is very very very small and hidden at the top. Also how can I add a second caller like a conference call or three way calling? Also I do not like the New Calendar app. In the iOS 6 app I could look at the entire month and the appointments I had for each day. IOS 7 forces me to look at the entire week only to see any appointments and they are spread out and not as user friendly or easy to access as iOS 6. And finally the tasks/reminders app seems like a big step down as I cant see the tasks I assigned each day of the week. Or are there ways around what I have mentioned? And finally what happened to the fully charged icon for my phone once it was 100% complete?
