Sorry but I cannot understand your english. If you have a native tongue, you can ask your question in that language and our members will help out.
Firstly, can you take a screenshot of your 620 on the settings page after you tap "more information" and I can give you further help?
^^^ I just installed the nokia installer and it says update available(1308.0002) whereas my phone update says there is no latest updates available.
Firmware version on my 620 is 1030.6407.1308.0001 which I guess is the same with the OP as well. Do I need to update the phone or shall I check with Nokia Care without committing? thanks!
