I've physically put my finger on a labeled 256GB USB drive before (it ended up being less than 100GB, and it was *dramatic pause* a scam)
So who's finger has more magical truth revealing powers???
There seems to be a bit of denial going on in this thread. Apparently I'm like a conspiracy theorist for having an open mind, asking questions, and not accepting conjectures. And also I'm not allowed to do math because it leaves an unaccounted remainder of ram according to numbers that I didn't even provide! Funny stuff, though you guys give me laugh sometimes...
The command "free" was executed to the Linux kernel itself, and that's how we can know the OS doesn't have access to more than 727040 KB Ram. You can verify that yourself from within any terminal emulator.
As I've said, I would be willing to agree that it's highly probable the rest of the ram is going to the GPU. Giving a GPU ~300KB Ram is not unreasonable. Though, if we assume it's not a scam, we haven't even proven that the GPU is actually using the Ram. It may be that there is a mistake in the system which causes it to inaccurately recognize all Ram. (We all know this phone suffers from another popular mistake *1.5Ghz*). So truthfully I don't really think it is a scam, but at the same time, I just think it would be foolish to take any possibilities off the table without some real proof.
Now I'm sure some of you're not too happy with me, but I mean no hard feelings guys. I really just meant to have an honest inquiry on this topic, and I feel like I've been trying to stay as objective as possible. And Rxpert83, I do agree with you about this- To know for sure, someone may have to contact LG (or perhaps qualcomm).
