My Android gallery was a 20,000-photo disaster — this is how I got it under control

I use my phone to capture product images and private moments, and in the last two months alone, I’ve taken around 1,045 photos. My Samsung Gallery app shows nearly 20,000 photos in total. Together, they occupy about 37GB of precious storage, with some photos dating back to when I was still in school, nearly 15 years ago.
