I have just solved a problem with the Maps app on my Samsung Galaxy I which was not answered in any of the advice I could find online.
The problem was that I couldn’t find Google Streetview, even though it was apparently correctly installed.
There is no option to delete the Maps app in Android, so I couldn’t do that and then reinstall it as I intended. So I just tried simply clearing the Data, without much hope it would do anything. However, when I re-started Maps it installed the latest updates and, bingo, Streetview was back again, working perfectly, as one of the options when you touch the down arrow on any ‘location’ box.
I don’t know anyone will see this, but if they do and they have the same problem I hope it helps.
