I have a lot of photos (over 1,000) in a Picasa file on my Samsung Galaxy s5. When I go to "settings", it is not on my App list, it is not being synched...anymore (it must have been at one time?) and I am unable to delete the photos in Picasa from my phone. When I select "delete" in the upper right hand corner of my drop down menu of my Picasa photos, I get the message "Unsupported File" and can not delete it. I do have a lot of photos in my Gallery that I do not want to delete. When I go to my "Gallery" app page on my phone, I have the following: "Camera", "Screenshots" , "Download", "Facebook", "Studio", "Videos", "Dropbox", and "Picasa". If I click on Picasa to open it, I can scroll through all 1,011 photos, I could email them, or I could share them on Facebook,...everything but delete them. How do I get them OFF my phone? I sure hope you can help.
