Some Android phones use (or used to use?) flash-friendly file system formats like F2FS, JFFS2, YAFFS2. I'm not sure if that's still a thing but it would be interesting to know the pros and cons of using one of those instead. Interesting I did find they are/were considering F2FS for the RPi: https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=2734...
