Reviews Word on the street

Galaxy S III mini  vs Lumia 620 

Outdoor visibility isn't very good, just like on most other AMOLED screens.
Galaxy S III mini

It's got a fairly reasonable pixel density of 246 ppi too, which while not as sharp as most high-end handsets is still good enough to produce fairly crisp images.
