Good try but...
Your people have your logo in a square box and android makes them all round so it adds a generic white circle.
You can see my MapleDots and DN favicons are uploaded roud so they will not get the generic white circle.
PS the dn favicon is now an app so it does not get a chrome icon when added to the home screen. That is the ultimate, it looks the best and there are certain things in the code you need to do to have that work but in most cases a round favicon like my mapledots one will do the job.
