This is my first post so please treat me gently! I have just retired from work and was given a Nexus 7 as a retirement gift. It is my first tablet and am gradually getting to grips with it but would appreciate some help with the following problem. I can't find a way to delete photographs currently backed up in the gallery. This is what I have been doing, rightly or wrongly. Click on gallery app in home screen. Select album, select location, highlight photos, click on trash can, delete photo, click ok. The photos are still there. I have switched off auto back up in Google Plus but still no joy. Thank you.
