Re: KitKat
I got it this morning about 5:30am.
Installed easily, no obvious problems.
Then I noticed that my home pages icons were missing.
Looking further, I found that many of my apps were no longer insalled, and a few were not in the "my apps" list in Play Store.
I have been able to re-install everything I can remember, and have only had one app fail to run properly. (A camping app - FMCA)
I'll be a while getting the pages restored and the apps tested, but no real big deal.
Was a little disappointed with the version "egg" - just a big black screen with a white "K".
