help which microsd is best to buy?

good day! i just want to ask if which in these 2 microsd is best for my smartphone? because i was confused with the details in the packaging…  the first picture shows the A1 printed in the pack which means fast mobile app performance…

while the second picture has no A1 in the package but has A1 printed at the microsd itself… that’s why im really confused if which one i will buy? and which of thede two microsd are the latest? 

btw im using samsung galaxy j7 core(philippines)



If the marking on the card has the A1 logo the card has the A1 capabilities. The packages are marketed for different things camera vs smartphone but the cards both have A1. 

I would suggest you buy the second one.

It supports 4K video and has faster read/write speeds than the other one.

I hope this helps!
