Questions about this item

Does my phone need a microSDXC slot to use this 256GB card?

Yes, the card is a microSDXC type so the device must support microSDXC; microSDHC-only slots cannot address 256GB.

Will the Class 10 and U1 ratings still record Full HD video in an older action camera?

Class 10 and U1 guarantee a minimum 10MB/s write speed, which meets the requirement for Full HD recording on legacy cameras.

How can I confirm the A1 rating is actually speeding up app launches after I move apps to the card?

Open the SanDisk Memory Zone app from Google Play; it shows read/write benchmarks and lets you verify app performance on the card.
