My wife and I both have Samsung Galaxy S2 phones, and use the GMail app for reading and writing emails.
In that app, when I mark a read mail as "unread", it throws me back into the previous screen and correctly marks the mail as unread.
When my wife marks a mail as unread, however, it does the same, but also adds a "new email" notification which then appears in the top bar - which really annoys her.
What is the cause of this behavior, and how can I fix it?
