Your compatibility chooser does not list this phone. Can it be updated?
I have an Ultra SDXC 64gig micro in my phone now. It didn’t require formatting in the phone.
Should I have done that, or am I good to go?
As a note, I pulled the battery before inserting the card. Some people have reported microSD cards being made useless in the Samsung GS3. I also experienced the problem. Any insight from SanDisk would be much appreciated. I can help spread the suggestions to several Android forums.
