I brought a galaxy phone for my mum from one of those cybermarts in Guangzhou. The original 8G ram was replaced with a 4G one. When my mum complains that the phone run slow, I was like "you installed too much crap-apps". Then one day I finally found out the phone was modified.

That doesn't make sense. It was probably the flash that was replaced.

NEVER trust those people at the cybermarts...buy from the Apple store, a certified Taobao store, or at a real storefront (though you still have to be careful). They will cheat you if they have any opportunity to do so.
