Hey, I'm using a Flip 5, and since the May security update, my RAM's been crazy high. I usually have like 3.4 to 4.3 GB free because I don't use many apps, and I've got no junk on my phone. I've got tons of storage space left, about 216 GB out of 256 GB. But now, after the update, I only have around 2 GB of RAM free.
