Again, I'm not a developer, but I assume your missing memory is being used by used by the parts android running native code. What's not clear to me is how android handles how much native memory an app can use. I got over my gaming fixation, but I'm still curious about this. If anyone can shed some light on this, I'd love to hear it.
I've checked /proc/meminfo and it looks like even the kernel doesn't see the full 2GB (assuming it is really there). MemTotal is 1,686,380 kB. Even if they were using 2GB==2,000,000,000 B, it's still missing over 150MB. I'd really like to know what is going on, but even Google support is completely clueless.
I'll probably just return it for something that lets me use the amount of RAM advertised.
