There were some reports suggesting the Samsung Galaxy S4 couldn’t format a microSD card. While the problem is not as common as connectivity and email issues, we did receive few emails from our readers related to it.
Again, the problem is rare so we weren’t able to replicate it. However, we were able to find some possible causes why a microSD card couldn’t be formatted with the Samsung Galaxy S4.
Temporary phone problem.
The microSD card is not supported.
The microSD card is damaged.
The card slot has been damaged.
The card itself is write-protected.
Based on these, the following are the things you should do to fix the problem.
Soft-Reset Phone. There were owners who claimed the problem was resolved all by itself. Thus, you cannot take away the possibility that it could be just a temporary problem. To soft-reset your Galaxy S4, turn it off and take the battery out for 30 – 60 seconds, put it back and turn the phone back on. Now check to see if the problem persists.
Unsupported microSD Card. You should remember not all microSD cards are supported by the Samsung Galaxy S4. Maybe you have bought one that isn’t on the list of the supported cards, so double-check on it. One way to know if the card is supported is when it is just an imitation of a branded product. If you bought it in an unreasonably cheap price, there is a possibility it is an imitation.
Damaged microSD Card. Damaged cards cannot be read by the phone, much less be formatted. If you’re trying to reformat the card and it takes so long for the phone to read it, there could be some problems. The best thing to do is to take it out and let your computer read it.
Damaged Card Slot. If the card is fine but the phone refuses to read or reformat it, the problem could may not be in the card but with the slot. You can take the card out and check to see if the connectors are well aligned. If they’re not, you should have an appointment with a technician to have it checked.
microSD Card Write-Protected. If the card was used in a previous device, it is possible that the card may be write protected. A write-protected card cannot be formatted. To remove the write protection, you will need to install the card in the original device and remove the write protection. If the original device is not available, you will need to use a different card in this device.
