When I click on various links the screen on my AT&T S3 will darken. For example, from the home screen I tap on the weather and the weather screen opens. I then tap on the location and, again, the new screen opens with no problem. However, if I then tap on an individual day from the six days at the bottom of the screen, a new screen opens and is much darker than it should be. It's so dark that it's hard to read. Any idea as to why this is happening?
