Great SD Card... just not good for phones,
Amazon Verified Purchase(What is this?)
This review is from: SanDisk SDSDQU-016G-U46A 16GB microSDHC Ultra Class 10 Card with microSDHC to SD Adapter (Accessory)
The SD Card gets a 5 because the space is more than enough and the class 10 is fine, however on my phone after a few months I kept on receiving error messages regarding the card. Upon further investigation it turns out that my Android phone, and many other formats like Windows, do not require a class 10 speed but a 2 or 4. I did think that there was an actual problem with the card but there isn't and is working fine on my PC. It is the phone because phones only require and go up to a certain speed before the limit is reached and the card is not longer recognised. This card though is good for a camera with the photos and video, like HD videos, with the adapter that it comes with shall be good for those who need that higher speed.
