There is a backdoor to the trash bin for mobile android users. Took me 4 hours of playing on my phone to bypass the system and find it. Its actually very easily accomplished on the Android phones and this us why they dont put it out there for users to know about it. You do not have a delete option on your actual GMail account. Instead log onto
https://mail.google.com. next press the gmail icon. In the center of the screen is your account displayed and on left is a three line paper. click on that icon. It will then display a drop down screen. You can then delete every file to include the trash by the box next to the message and a drop down screen will appear click delete forever. Saves waiting 30 days fir the trash bin to refresh. Hope this helps for people like me who like their privacy within a relationship.
