Is this the one that very cleverly removed the full contact list from the Phone 'app', changed the Take/Deny call orientation, and made everything 200% bigger? Because I [expletive] hate it and don't see how in any way it's better.
Now I have to open up the contact list, a completely seperate 'app' to call someone if i can't quite remember who they are, so can't use the Phone's search functionality. So dumb. Well, it's trying to be smart, but I want it to stay dumb.
I wish we could preview these things and decide if we want them or not, rather than waking up to find the phone's decided to wear a new change of clothes and we have to tickle it differently to get it to do what we need (not want, NEED).
You can disable updates, it's the second thing I do on every new phone. (The first thing I do is disabling sounds.)
I was frustrated with some other change to Phone a while ago and was angry but then decided to just make the mental switch to Contacts as my main entry to phone long ago. I only ever go into phone directly if I need the dialer. But frankly I can't say I use phone itself much anymore, mostly I use some form of messaging. (But I have used Niagara launcher for a long time so finding Phone when needed is super easy/fast)
You can still get the full contacts list. Press the menu button and then press "Contacts".
