I've just updated my Galaxy S3 to the OTA 4.3 update and whilst its fine, there are a couple of really annoying niggles.
The main one is the notification bar at the top - where the little icons are shown. This used to be black with white icons and they were easily visible.
Now its transparent.
I use a nice landscape image as my wallpaper, so I have pale blue sky and white clouds, and you can imagine the white icons on white cloud background isn't exactly what I'd call usable. short of editing my wallpapers to have a black bar at the top, is there a way to revert this?
It seems the update is fine but for the lock screen that has so many pointless changes that result in usability problems I'm tempted to downgrade.
