Can I use a 256 GB micro sd card on a phone? Uncategorized July 9, 2021 Forums AndroidCentralLeave a Comment on Can I use a 256 GB micro sd card on a phone? I don’t have the latest phone nor do I have an old so I was just wondering if I could use an sd card with that much storage with my phone. Currently, the phone I own is a Samsung A50 with 128 GB.
