Tips:

Flash memory vendors are using decimal arithmetic: 1MB = 1000KB， 1G = 1000MB calculated， and the operating system using binary arithmetic: 1MB = 1024KB， 1GB = 1024MB so there are some differences between display capacity and nominal capacity of flash memory products. 2G is about 1.82G， 4G is about 3.6G， 8G is about 7.2G ，16G is about 14.4G ，32G is about 28.8G.

 

What\'s Upgrade Micro SD?
Upgrade Fake shows real capacity on your PC， you will see the cards is the same as they looks 
You can only test fake card by using software like H2testw software 
Fake cards troubles everyone anytime ， for example， fake 32GB is usually upgraded from 2GB/4GB， seller get it at 2GB/4GB price and sell it at 32GB price， that sounds nice but please don\'t be cheat ， That is cheater.
In that fake card， but if your photo or video exceed real capacity， all rest files will be damaged， You will lost all file ! Lose all your photos and videos，what a nightmare!!!!
