Most important thing about a card is it's class. There is no class mentioned, it is usually on the card itself. What is the class?

The large C with a number inside is the class. THIS IS class 4

is it compatible with samsung galaxy s3

Yes, it is compatible with any cell phone with a MicroSD card slot.

does this micro sd card work for a LG optimus dynamic 11 cellphone?

Not 100% sure, but works with a Nextbook 8" tablet, Samsung "slider" cell phone, PC USB port, etc. Only thing, make sure the LG Optimus dynamic 11 (see manual) can use a microSD as large as 16GB.

What is the actual size of the SD card? We are looking for an SD card that is 0.5"x 0.125".

didn't realize that there were different size micro sd cards but this one is marked as the smallest memory card that can be bought; at 15 mm × 11 mm × 1 mm
