Is there a list of what is missing when compared to using a PC?

I have been trying to use it but so far is missing:

1. Photos uploaded by users (small points of interest)
2. Map/Satelite overlay
3. Being able to use street view by moving the 'little man' in map mode
4. Zooming out to maps when in street view

It seems quite limited for some reason. Is there anything else missing from the full version when using on a phone or tablet?

Not really interested in 1, but all the others work for me.

Are you using Google Maps with the Street View addon?

Yes, but still not working right. I will take it up with my provider (3).

your provider of what ?
it's nothing to do with your data provider if that's what you are thinking.

Well it may not be their fault but they are the only place I can go in person and show the problem too. I tried to download the application from the Google Play site but it says I already have it. Something is amiss somewhere.

i doubt they will offer Android technical support

The versions of Streetview on mobiles and similar (I use an iPhone) are completely different from the PC version.

If you want to take it up with anyone, you would have to go to Google, but I shouldn't think you would get anywhere as the App is probably doing exactly what it is designed to do.
