When i first got my phone I'm sure I was able to search for titles and subjects in the Play Store. But now whether I type it in or speak, the Search does nothing. There is a brief screen flash but I see no sign that the results are present. I think I saw something about a Samsung or Sprint update which affected search inside the phone, but isn't the Play Store outside the phone's system? The search in my contacts still works well. What happened to my phone? Has anyone else had this problem.
