Google One gives you an itemized look at what is using your storage space. All of the Google Apps are represented, device backups, and individual apps that are using Drive for storage too. I’d presume it would point you in the right direction, without needing to manually download everything and sift through.

TL;DR: Samsung is better, according to the author.

Some questions remain though, as Google’s Magic Eraser gives multiple options for object removal. Some are quite bad or blotchy, others are nearly seamless. Don’t like any of the options it’s provided, then ask it to try again. The author doesn’t touch on this at all. Did they select the first option everytime? Was this the best of the options they were provided?
