Restore brightness


I`m using Android 4.4.4, tell you from the beginning because it may help to give me some good tips for my problem . A few days ago the Recent Apps display changed on my Z3C and now I get full brightness trash can icon, but the app thumbnails are all dimmed. This screenshot it`s really bad, can`t take it !
I want to know how to restore full brightness to the app thumbnails... Please, help me !!! Thanks in advance !


Are you sure you have the auto brightness off? If it's on it won't let you adjust it to your liking. If not I suggest you backup your data and reset your phone. Last step would be to contact Sony to find out about your warranty. Hope this helps!
