I am having 3 different very recent problems with my Nokia Icon.
Contacts : My photos I have linked with my contacts have disappeared except for those with Facebook photos. Also, contacts I had pinned to Start who had been there for over a year and a half disappeared 3 days ago and I had to pin them again.
Calendar: On Oct. 30th my upcoming events were set back a day. (i.e. a meeting on Monday Nov. 7 was now on Sunday, Nov. 6)
Message/Text app: Some messages won't open and instead say "Get media contact now" even if it is only text. When I try to do this, the message changes to "Getting media content...." but it doesn't change. I have a thread that was all text change to this and now nothing will open in that thread.
My phone checks for updates regularly and automatically, running Lumia Denim. I have not made any changes to my phone and I have received no error messages. I have powered the phone off and back on but that doesn't change anything.
