I bought my first iPhone a year ago, before that I had Android phones. I'm still not that familiar with Apple /iPhone and still tend to use Google etc. I've always saved photos to Google photos and on the iPhone they're also saved on the Photos app. I've just had a message saying my iPhone storage is almost full and I can either pay for more or delete photos. I've tried deleting a couple to test if they disappear from Google photos which they don't so do you think I'm safe to delete all from the iPhone photo app? Just seems a scary thing to do. Anyone else done this?
