IOS 12.0 update fail: (tele)phone screen frozen: keypad / voicemail inaccessible
Just updated to IOS 12.0 today on my iPhone 6. SERIOUS PROBLEM that I haven't seen described elsewhere:
The (tele)phone screen is frozen; currently stuck on RECENTS (calls) / ALL, and will not scroll up or down or respond to clicks from (tele)phone screen to VOICEMAIL, CONTACTS, or KEYPAD. Similarly, there is no access to FAVORITES, or MISSED, or INFO (about specific calls), or EDIT. All these normal usages have been rendered useless thanks to the 12.0 update.
As for actual telephone calls, I cannot use the KEYPAD to dial a number, but I can make calls to my contacts (only) by going through CONTACTS on the main screen. I can receive incoming calls. Incoming calls are logged in the RECENTS but I cannot access any info about these calls. Outgoing calls (only going through my CONTACTS of course) are logged. VOICEMAIL is not logged in the RECENTS; presumably all post-12.0 update VOICEMAIL is being lost.
No other loss of functionality about this previously perfectly functional iPhone 6 has been noticed. PLEASE HELP!
IOS version 12.0 (16A366)
