I have a Galaxy S3, only a few months old. In the last week or so, it has started to exhibit a few strange behaviors: 1. Unread email count: on the stock android email client, I have 3 IMAP email accounts registered. The Email icon on the home screen has a red circle that is supposed to show the number of unread email addresses across all accounts. Up until the last week or so, it worked fine. Now, the email count is stuck at "4" regardless of how many unread email messages there are. 2. Lock screen. I have the system set to return to lock screen after 30 secs of inactivity. However, over the last few days, I've noticed that the lock screen does not activate. I know these are relatively minor issues, but am concerned that is something wrong causing them that could develop into larger problems. Any thoughts on what might be wrong and/or how to fix? Thanks.
