Boy Genius Report has written up a possible browser privacy issue with the HTC Incredible and Sense UI.
The Incredible, with Sense UI, will periodically store screenshots of the contents of your web browser. The screen captures are a function of the HTC Sense UI bookmark widget and are not the main issue; temporary screen grabs are understandable. The problem is these JPEG files are extremely hard to get rid of. They remain when the current browser session is closed, they remain after you clear the browser history, and they remain after a full factory reset.
Are screenshots of your web browsing history being taken and kept within your HTC Incredible? Read the full story for details on where the images can be found.
