I want to buy a 32 GB microSD card for my phone (Micromax A52). It was released in June 2012 and runs Gingerbread. Now I know that my phone supports 32 GB microSD card, but I am not sure if it will support a class 10 card. A certain website is offering class 10 32 GB microSD card for 16.231 USD. I am also planning to get a new phone in the future but for the time being I will use my A52, therefore I wanted to purchase class 10 instead of class 4 or 6 . So will my A52 run slow if I put a class 10 microSD card into it?
