Use a class10 SD card and from a good manufacturer but beware of sites like Amazon that have been known to sell fake cards, so purchase one from a store and to be doubly sure use a program like H2testw to perform tests to make sure it's not fake before using it
Hi,
Note that Xperia ZR has only been tested with memory cards up to 32GB. A 64GB should not be a problem, but we cannot guarantee anything.
If it is a problem then use a program called guiformat which will allow you to force format the card to Fat32 or you could create 2x 32GB partitions
