> wow those people are lucky and high on consumerism, my phone had 2GB. How? Lollipop, the first Google hit for "Android OS size on phone" ( https://android.stackexchange.com/questions/118896/how-much-... ), seems to be about 5 GB. (Maybe you don't run Android, or maybe a very old version?)
What usually happens with these phones is they have something like 8GB or even 16GB, but they are poorly paritioned. It could be something like 5-6GB for /system (the OS) and they somehow only leave 2GB for the /data partition. I've seen a phone like this running Lollipop. The best part is when it decides to auto-update all the built-in (Google) apps, collectively consuming a total of 1-1.5GB of /data, at which point…

which is clearly referring to the pre-OS available space.
