Thanks for contacting SanDisk Technical Support. It is our goal to make sure you have all the resources you need to get the most from your product.





Please allow us to inform you that

128GB microSD cards are built to conform to the microSDXC standard and since your phone is currently working with a 64GB microSDXC card we see no reason why the 128GB microSDXC will not work; however we have not tested it so can't guarantee one way or the other.
