@abasket - I have way more photos and videos on my phone than you do. How much storage does your phone have? I have 128 GB and am almost at the limit - happens every vacation.
I use google photos - gave up on the deleting/trying to save space idea a few years ago and it’s been the best thing for me. I pay a 100$ for the year and all of us share the storage. And we have several hundred GB of data. The other cool thing is that I was able to upload all the old digital pictures (going back to circa 2000) to google photos - it took a while to do this, but now in a couple of clicks, I can pull up any old photo!
I plan to digitize my older albums and move them over too - when I have time! Might have to wait until retirement though…
