What 64GB do I need to use that's easy to format?

[AC Question]

Silicon Power 64GB up to 85MB/s MicroSDXC UHS-1 Class10, Elite Flash Memory Card with Adapter . . .
I recently bought this card for my Unimax U671C android smartphone from Amazon.
The phone's instructions say that it will support a card that size but even after trying to format it on the phone and on my PC, I still get the message that the phone will not recognize it.
The ad for the card says that it will work in smartphones.
Is there a card that size that will work with no problems?

Did the phone actually go through formatting the card? If you connect the card to the PC, can you place files on it, and are those files readable from the card? If you can't get any files to transfer to it on the PC, then the card might be bad. You could also have a bad SD card receptacle on the phone. Does any SD card work in the phone?

I normally use Sandisk SD cards... mostly because I buy them at Costco. I've had no problems with them over many years. I've heard Samsung SD are good also.
