The combination of small font size, low contrast color schemes (gray on gray), and the erratic operation of the auto-intensity makes the screen difficult to read in many circumstances.

I like auto-dimming, but I think it follows the wrong curve and is often too dim for the ambient conditions. The only alternative is to disable the automatic function entirely, which still results in often having the wrong brightness.

Can anyone recommend the simplest approach to customizing the font sizes and colors for the JB user interface? I liked Gingerbread's UI, but would prefer stick with the JB OS if the UI could be made more like GB.

  • When dealing with an automatic feature that is IMHO very useful, and that "almost works", I'm the type of person who wants to find a way to fix it, rather than give it up entirely and use a manual method. I'm hoping somebody will say "oh, the auto brigheness curve is in file abc.xyz, just edit the table there"

  • Also worth a look: Spare Parts Plus. Amongst others, it lets you adjust the font size.
