When I receive and email with an attachment, it could be an excel spreadsheet, word doc or PDF there is a small thumbnail picture that shows in the open/save box. Lately the picture has been a nakid woman. These pictures and not stored on my phone. I am not sure where they are coming from. I use this phone for business and I am concerned that these pics are showing up in emails that I send to my customers. What is going on? Anyone else having this happen? I don't want to get rid of the phone but I cannot risk this happening. Any help please????
