Hold down your home button, press RAM, and see how much RAM you have(number to the right, highest). Mine says 373mb and I called Samsung since the Charge is advertised to have 512mb and they said that all Charges have 373mb since their model they claim to have checked on said the same, but they insured me the RAM is still 512mb on all Charges. I'm thinking they don't know what they're talking about, but I just want to see if they're right. Anybody else have this possible issue?
