Lumia 1320 :: Phone Won't Auto-rotate When Browsing

Recently bought my wife a 1320, as my son loves his 920 and she was getting sick of her Galaxy S3 having issues following an update, which has messed her phone up !All was going well, but she's now finding that the phone won't auto-rotate when browsing - it works fine when viewing photos or texting etc., so assume the accelerometers are working ok..

Also, have changed settings on outlook, to remove US holidays and have added UK holidays, but the UK dates haven't pulled through to the phone......am I missing something `?Lastly - blootooth keeps dropping out.
