Is there any regulation regarding advertising of tech gear (USB, smartphone)? The usable memory is always lower than the advertised memory so how many percent of the advertised memory must they fulfill? Right now I am looking @ my smartphone: Advertised RAM: 256 MB, Real usable RAM: 112 MB Plus the already low 112 MB is always at least 80% used I know they must use part of the RAM to run the android system but less than half of the advertised RAM, seriously! And this is from a reputed brand name. What is your thought on this.
