Samsung Galaxy S7 Edge - Micro SD Card not recognized

I received my Samsung Galaxy S7 Edge today. Before  first power-on, I installed the new SIM, and a fresh PNY 128GB Micro SD card with 128GB. The phone went through normal setup, and transferred my information from my old S5 to the new phone just fine.  I _WAS_ able to see and access the SD card. After about 3 hours, I noticed a warning message that the micro sd card had been removed. Rebooting did not help, reinserting the Micro SD card did not help. Checked the Micro SD card on a computer, and the card is fine.

 

A check of the XDA message board shows a significant number of people reporting this same issue.

 

Has either AT&T or Samsung issued a statement about this?  If the phone cannot use the Micro SD as promised, I'll need to return it. I also bought one for my second line, don't know if that phone is having the same issue yet.  Either way, this has to be fixed or the phone has to go back.

Just because you were able to view files from the SD card on your computer does not mean that there may not be a corrupt file on the card. I would recommend to copy everything to your computer then put the SD card back in your S7, go to Storage and then format the SD card so that way you know the file system on the card is compatible with the S7.

Hello @ByronJones,

 

Thanks for posting! I am happy to discuss this with you.

 
I’ve also noticed the microSD card posts across multiple forums (for all carriers.) It appears that certain brands of microSD cards are having a higher success rate than others, however Samsung has not yet released a statement regarding this. Others have posted no issues whatsoever with their S7/S7 Edge with a microSD card. We’re currently collecting examples and appreciate you taking the time to let us know about your experience.
 
If you haven’t loaded too much data on the card yet, please re-format it before inserting it back into your Edge. Or, if the Edge does recognize it, please re-format it within the Edge settings.
Please let us know the outcome, and also if your 2nd S7 Edge is experiencing the same issue.
 
Cheers,
-JP, AT&T Social Media Manager

I have a Samsung Edge 7 with a 200GB micro sd card from Scandisk.  The micosd card has been working great up until recentely.  Now, whenever I go into my setting > stroage, I no longer the info for my card.  It also looks like all of my pics and videos are now being saved on my internal storage.

 

1) is there a way for me to troubleshoot this problem?

2) how do I possible reformat my sd card?

 

Thanks,

Mike

I have an S7 and I put a 128GB sd card in and it was working fine and then one day I saw that the apps I had on it were not installed. I also can't see the card to reformat it. I put in a 2gb card which it has no problem with so I'm thinking the larger GB cards may be the issue?

We definitely apologize for the troubles you are having with the memory card that you have in the device! Are you still having issues with it being read on the device?

 

We can recommend connecting it with an adapter and seeing if your PC can read the information on the card. If so, great! That means that the memory card is working as it should. You will want to save that information and format the card to the PC.

 

When you place the memory card back into the mobile device, it should automatically read the card.

 

If you are still having issues with the mobile device reading the card, you will need to refer back to the manufacturer.

 

Hope this helps!

We do apologize for the inconvenience! I know myself personally, I require a good amount of memory on my phone as well so I definitely want us to come to a great resolution!

 

It is seeming as though it might be an issue with the larger GB memory card, especially if the mobile device responded with the 2GB card when you placed it into the device.

 

We can recommend connecting the 128GB card to an adapter and seeing if your PC can read the information on the card. If it does, perfect! That means that the memory card is indeed working. You will just want to save all the content to avoid losing anything, and format the card to the PC.

 

When you place the memory card back into the mobile device, it should automatically read the card.

 

If you are still having issues with the mobile device reading the card, you suggest referring back to the manufacturer.

 

Hope this helps!

I have a Galaxy s7 Edge and my phone is not reconizing my SD card. My card is a 16GB and the phone is not showing that I have a SD card in it. One day it was working and then it wasn't. With the last update it stopped working. My husband has the same problem and he has 2GB SD.

I am going to raise this as a top level issue. First off I am a tech guy. I work as a systems administrator and deal with smart phones, computers etc. I cover the whole spectrum.

I have done all the testing needed to determine that this is a result of a software update that is breaking the sd card reader from reading sd cards on a large number of phones. I have an ATT galaxy s7. When I bought it read my 32 SD card without issues. I had a cosmetic issue with my phone so I had to restore it back to factory and sent it to Samsung to have checked out.  When I put my SD card back into he unit it no longer recognized it and said it was unsupported. I then proceeded  to put my other 2 working SDcards  into the S7 and it was the same issue.

All 3 of these SDcards  work fine on my 2 Samsung tab 3's, my note3 and inside 2 S7's that I have in my office.  I even took the working sdcards that are inside the other 2 S7's I was testing on and moved them to my s7 and both were NOT recognized.

 

if you try to format the SDcard inside the phone it will always throw an error like this but with different partions #'s. That means the SD slot is working but the code that would call the format /write  commnd it corrupted or the OS is not able to go into write mode.

 

command '12 volume partition disk:179,64 public' failed with '400 12 command failed"

 

With that said either Samsung or ATT are liable for this problem. It is outrageous that the amounts of people that are posting on the xda forums have the same issue. There is clearly a bug in the firmware or due to an update that is affecting a large audience. When customers shell out $600 + for a smart phone and they can't leverage the expandable storage which is one of the main selling points of a Samsung device is 100% unacceptable. Samsung and ATT and all of the cell phone companies know darn well that this is a major problem. A recall needs to be initiated. 

 

It is up to us as the customers to band together to escalate this to the masses. I will be posting this across the entire website and hopefully they will call come here to stamp their exact same situation of a defective firmware. 

There are probably internal memos being passed around regarding this issue. It has nothing to do with SD cards over 128gg. That is hogwash. I am using a 32 GB SD card and the 2 other S7's I have tested with are 64 GB and 128 GB respectively.

 

ATT and SAMSUNG it is time to open up the forum and tell us what is really happening here.

 

I am that close to changing to T-Mobile and getting a free trade in of my ATT branded S7 for a T-Mobile branded S7. At least I have a fighting chance to get a working SDcard slot.

 

We want answers now!!!!!!!!

 

Here is the XDA forum threads that are 7 pages long of people with the same issue.

@Shiney69rr I read that you are a tech guy and that you work as a systems administrator and deal with smart phones, computers etc.  As posted in earlier post on this thread it is happening on all carriers, so why do you think that if you leave to T-Mobile and go with Samsung that you won't have the same issue?  Shouldn't you be reaching out to Samsung as they are the ones that make this phone?  The software it first designed by Google, then Samsung tweaks it a little and same with AT&T, but since this issue is across the board with all carriers that would mean that it is either an issue with Google or with Samsung.  Oh yeah, this is a customer to customer forum, so you may or may not get the people that you need to get to fix this issue.
