Okay stupid question probably but I just noticed this today. When I open browser to view Web pages the brightness is significantly lower than the screen would be outside of the browser. I always keep my brightness settings for phone and browser (hit menu button while in browser) on the auto setting. But when I open the browser its almost un readable because of how dim it is. Every other app and normal phone dimming works normal, just browser that I can hardly read
I can override the auto setting and adjust brightness all the way up but then auto dimming won't work...
Maybe you have the 'power saving' mode on. Check in the toggles and make sure it isn't selected
