best buy wants almost a hundred dollars for this chip.it works perfectly in my samsung galaxy S111.  this is a outstanding phone.it was updated to jellybean 4.3.  it works flawlessly.i now have all the memory that i need in my phone.the sandisk warranty is outstanding.i doubt that i will ever have to use it.if you need to buy any chips,get them from amazon,they are much cheaper.best buy is getting greedy.
