Samsung Galaxy S3 accepts Micro SD memory cards with maximum capacities of 64GB. This extended capacity will come in handy if you’re planning to store lots of picture, music and video files on your phone.
However, your Galaxy S3 may not have shipped with a SD card, so you may have to buy one.
And, once you’ve got it, follow the steps below to get it installed to your Galaxy S3.
- Turn off the phone.
- Remove the back cover. (Be cautious, the thin plastic cover is a bit flimsy)
- Slide in the SD card with the gold-coloured contacts facing downwards into the card slot until it’s secured.
- Replace the back cover.
- Turn on the phone.
- On home screen, press the Option key > Settings > Storage and scroll down to the SD card section, you should see the memory card information in Total space and Available space fields
- Since it’s a brand new memory card, you should (but not compulsory) do a format using the phone’s format function to make sure the card file systems is fully compatible. Tap Format SD card and follow the on screen instructions to complete the formatting.
- Done. The memory card is ready to be used.
- On My files app, the external SD card memory appears as the extSdCard folder.
- When the phone is connected to PC, you’ll see an additional card storage in Windows explorer.
