 I am using android torbrowser 9.0.5 on a samsung galaxy ring which is a
 small 4" phone. When i check the fpcentral site or panopticlick.eff.org, i
 am seen as unique with the panopticlick site showing ~1/45,000 because of
 the 3 resolution factors: screen width, screen height, and color
 resolution - 320, 508, 24 - and ~1/250,000 overall. I have read that
 torbrowser is supposed to give a certain resolution of a set of proscribed
 general resolutions, to anonymize the user, depending on the size of the
 actual screen. However, in my case, the screen resolution is specific, and
 the small screen is a giveaway too. The developers at the torproject have
 to take this into account and set the screen resolution of such a small
 screen ti spoof a larger one and larger, more ubiquitous phones.
