I have the BLU Android 10 SmartPhone. I wanted to get a 256 GB Micro SD Card. I was going to get a Class 10 Card because it will Write at 10 MBps. I know a Card that says "U" with a 1. Inside it will Write at 10 MBps as well but you need a UHS Device to use it if I am Right? I found this on Amazon https://www.amazon.com/SanDisk-256G...x=256+gb+micro+sd+card+class+10,aps,79&sr=8-3 Can this Card be used with Both Class 10 Devices and UHS Devices?
