UPDATE on My Mini Kit-Kat-Mini problems. After having my Mini 'bricked' during the Kit-Kat install shortly before Christmas, I was reluctant to try the upgrade again on my replacement phone. However, this past week, the Kit-Kat update was pushed out to my phone again. I delayed the installation, until I talked to the VZW store where I had taken my old phone and was advised about update issues. The store personnel were of mixed opinion, but the consensus was I should try it. So, I did install the update yesterday. And, I can report this time it did complete normally. So now my Mini and Nexus7 are running the same version of Android. personally, I don't see any difference in performance between the previous version and this one.
