I have been looking for the best way to use a browser that supports flash on android for a long time. I've always used the stock browser and chrome. I tried Puffin as well which is the best browser in a range of benchmarks (look for a post comparing android browsers on my blog) but it is only the best for american users. Keeps telling me that I can't watch BBC iPlayer programmes, for example, because Puffin's servers are in America.
Then came the Dolphin browser. The bonus is that it's visibly fast. I thought I was connected to a 4g network. See how this browser can let you use Flash even if you are on jelly bean.
