s9 sd card issue

What to do if your SD card is not detected on your Samsung Galaxy S9 (easy steps)

A prompt solution to insufficient storage issue in mobile devices is the use of SD card. It provides extra storage space to allocate more files and media contents. However, not all SD cards work smoothly on every device given the diversified SD card support system. SD card mounting issues in mobile devices are usually attributed to different factors. Among common culprits are not supported SD card type, corrupted SD card, and damaged SD card , SD card slot, or device itself. In other cases, a device may not be able to detect or recognize the SD card simply because the card is dislodged or not installed correctly. Here in this post, we will tackle a pertinent issue on the new Samsung Galaxy S9. Find out what to do if your SD card is not detected on your new Galaxy handset.

The new Samsung Galaxy S9 and S9 Plus support microSD or TransFlash memory card types, preferably class 10, UHS class 1, 3 or newer memory card types. To rule incompatibility issue out from the underlying cause, verify and ensure that you are using a compatible microSD card. Otherwise, consider replacing it with the right card.

If your phone still cannot detect your SD card even if it’s the correct card type, then move on and troubleshoot software issues on your Galaxy S9 that might have caused you this trouble. And here are your options.

Before going further, if you found this post because you were trying to find a solution to your problem, then try to visit our Galaxy S9 troubleshooting page as we’ve already addressed most of the commonly reported issues with the phone. We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

First solution: Remove and reinstall SD card.

Sometimes, a device won’t be able to detect or read an SD card simply because the card is dislodged or covered in dirt. To make sure this isn’t causing you this trouble, try to remove the SD card from your phone. For safe removal, be sure to unmount before removing the SD card. Here’s the proper way to remove and reinstall SD card on your Samsung S9:

  1. Unmount the SD card by going to Settings-> Device maintenance-> Storage-> More option-> Storage settings-> SD card-> then select the option to Unmount.
  2. Turn your phone completely off.
  3. With the display facing up, head over to the top corner of your phone and then remove the card tray by inserting the removal tool or a paperclip into the provided slot. Doing so will unlock the tray.
  4. Gently pull out the tray and then remove the SD card.
  5. Check the card for any visible signs of damage or dirt. If there’s none, insert the SD card back into the tray with the gold contacts facing down.
  6. Push the card tray back into its slot then press in to secure it.

Turn your phone on again and test to see if the SD card is already recognized. Most devices will automatically mount an SD card after it’s inserted into the SD card slot. But if this isn’t the case, then you can mount it manually through the Settings-> SD card and Phone Storage menu. Finally, tap the option to Mount SD card.

MicroSD card cleaning tip:

  • If there’s a need to clean the SD card, you can use a white colored rubber eraser to gently rub the copper piece or gold contacts on your microSD card to remove any dirt. You can also use some nail polish cleaner, dab it in with a Q-tip then gently rub it over the gold contacts of the SD card. Doing so can help detach any erosion. After cleaning, allow the SD card to dry out and then plug it back into the SD card slot on your phone. After securing the SD card tray, turn your phone on. See if you find any luck from the prior workaround.

Second solution: Test SD card on your other device.

To determine if your SD card is working or not, try to insert it into your other devices that support the same SD card type. If the SD card is recognized by your other device, it means that something is preventing your S9 from reading the card but the card is working. In this case, you will need to find out which from your phone’s system components is the culprit. Again you can start by booting your Samsung S9 into safe mode and diagnose third-party apps. Refer to the next procedure.

Third solution: Boot your phone into safe mode.

All third-party apps are bypassed or temporarily disabled in this mode so it would be easier for you to determine whether or not the issue is triggered by a third-party app or not. Here’s how to boot your Samsung S9 into safe mode:

  1. Press and hold the Power button until the Power menu shows up on the screen.
  2. Touch and hold (long press) on the Power off option until it switches into a Safe Mode option.
  3. Then tap on Safe Mode.

Your phone will then automatically reboot to safe mode. You should see a Safe Mode badge on the bottom left corner of the screen. If your phone is able to recognize the SD card while in Safe Mode, then it means that a third-party app is to blame. In this case, you may need to uninstall the most recent app you’ve added and then test your phone.

To uninstall an erratic app, go to Settings-> Apps menu, then select the app you want to remove.

If the problem persists while running your device in Safe Mode, press and hold the Power button then tap on Restart to switch back to normal mode. Proceed to the next applicable solution.

Fourth solution: Format your SD card.

If your SD card is new and still empty, you can format it directly. However, if you already have stored some files in it, you will need to do a file transfer first as they will all be wiped out in the formatting process. You can move your SD card contents to your computer through a card reader. Once everything is set, follow these steps to format your SD card:

To format SD card on your Samsung Galaxy S9, follow these steps:

  1. Swipe up on an empty spot from the Home screen to open the Apps tray.
  2. Tap Settings.
  3. Tap Device maintenance.
  4. Tap Storage.
  5. Tap Menu.
  6. Select Storage settings.
  7. Tap SD card.
  8. Select Format.
  9. Tap Format again to confirm action.
  10. Wait until the SD card is completely formatted then tap Done.

Restart your phone and see if it’s now able to detect your SD card.

Fifth solution: Hard reset your Galaxy S9 (factory reset).

This should be considered as the last resort if all else failed to fix the problem and your Samsung S9 still cannot detect your SD card. A full system reset will likely fix the problem especially if it’s triggered by a complex system error on the phone. But it’s also worth to note that this reset will wipe all your data including personal settings and information stored on the internal memory. That said, back up your phone before you proceed with these steps:

  1. Tap Settings from the Home screen.
  2. Scroll to and tap on General management.
  3. Scroll to and tap Reset.
  4. Select Factory Data Reset from the given options. This will wipe out all your data and personal information from your device. Bugs and software glitches are also obliterated in the process thus gives your device a clean fresh start.

Wait until the reset is finished and your phone reboots. Proceed with the initial device setup and try to mount your SD card again to see if it’s now recognized by your phone.

Seek further assistance

Contact Apple Support and seek further assistance and other options if your Samsung Galaxy S9 still cannot detect any SD card you tried to insert. There might be a more serious problem on the device that needs to be fixed by a technician or intricate system error that needs to be dealt with on your phone.

Steps on how to insert a microSD Card to a Galaxy S9:

Inserting an SD card to your Galaxy S9 is easy. Below are the 5 easy steps to do it. Be sure that you have a microSD card for this task. If your card is too big, try to use a microSD card instead.

  1. Prepare the ejector or ejection pin. This is the metal pin that comes with the phone when you first unboxed it. If you lost or misplaced it, you can use a paper clip instead.
  2. Using the ejection pin, carefully insert it into the hole on the SIM card or SD card tray.  This is located on top of the phone. Be sure not to pick the microphone hole which is also located on top.
  3. Once the SIM card or SD card tray pops out, gently pull it out.
  4. Place your microSD card to the SD card slot in the tray.
  5. Insert the SIM card or SD card tray into the phone.

Once you’ve added the microSD card properly, be sure to format it to minimize bugs from developing. This is important especially if the said card has been recycled or used in another phone.

Steps on how to remove a microSD Card from a Galaxy S9:

Removing an SD card from your Galaxy S9 is very similar to inserting one. Here’s how it’s done:

  1. Before you remove the microSD card tray, be sure unmount the microSD card first. This  will prevent the microSD card or your files from getting corrupted. To unmount the microSD card, just go under Settings > Storage > More Options > Storage settings > SD Card > Unmount.
  2. Prepare the ejector or ejection pin. This is the metal pin that comes with the phone when you first unboxed it. If you lost or misplaced it, you can use a paper clip instead.
  3. Using the ejection pin, carefully insert it into the hole on the SIM card or SD card tray.  This is located on top of the phone. Be sure not to pick the microphone hole which is also located on top.
  4. Once the SIM card or SD card tray pops out, gently pull it out.
  5. Remove your microSD card from the tray.
  6. Insert the SIM card or SD card tray into the phone.

What to do if Galaxy S9 Plus wireless charging option disappeared

Hello Android fans! Welcome to the latest troubleshooting episode for the Galaxy S9 (#GalaxyS9). As usual, we bring you some of the common issues for this device. We hope you’ll find this helpful.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: Galaxy S9 Plus freezes when SIM card is inserted

Hi. Recently picked up a nice shiny S9 Plus, charged it all up all files & apps transferred from my old tired S5 Duos and everything works great. but then I add the SIM, I restart the phone and on every single occasion it hangs on a black screen. Nothing displays at all, no logo or message. All I see is the blue indicator light pulsating away. To resolve it I have to do a soft boot then everything works. Any idea what is going on as this phone isn’t the cheapest and it feels like I am back in the days of Windows 95 constantly hanging? Be great if you have a solution, apart from take the SIM card out that is. Thanks.

Solution: When it comes to electronics troubleshooting, there’s no clear cut solution for everything. If you’ve isolated the cause of the problem to the SIM card, then you should focus your efforts confirming that first. So, the first question that you want to ask yourself is this: Does your new Galaxy S9 Plus work normally without a SIM card? If the answer to that is yes, then the SIM card is probably interfering with Android. If your S9 Plus is part of your carrier contract, then you need to ask them for further assistance. There may be a unique bug in their firmware that only them is aware of. Alternatively, you want to see if the bug can be fixed by installing the latest update (that is if you can reboot the phone normally and check for updates under Settings > Software update.

We assume you have a brandnew S9 Plus so if it was purchased separately (and not provided by your carrier), you can try to factory reset it first. This will allow the system to get rid of temporary issues that may have developed after setting the device up. Once you’ve factory reset the device, re-insert the SIM and see what happens. If the problem returns after that, you should contact Samsung so they can take a look and advise you on what to do. They may either repair or replace the unit.

For reference, here are the steps on how to factory reset your S9 Plus:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Problem #2: Galaxy S9 apps not getting notifications

Hi. i’ve been receiving the notification to update my phone software for quite some time but kept delaying. Yesterday suddenly my twitter and telegram notifications are not working so i decided to install the software thinking that it may help. However after installing even my instagram is not receiving notification. i’ve tried to restart, on and off, checked all the notification settings both in the app itself as well as in the general notification setting. its not working for some but working for others. I read online to uninstall Security Master App/ sweep, but i cant find any app by that name in my phone nor in the settings. please let me know if you have a solution to my problem. thank you!  Best regards.

Solution: If you’re positive that notification settings for the apps in question have already been set properly, then one of the troubleshooting steps below should help you resolve the issue.

Reset app preferences

Apps need other default and third party apps or services in order to work. Sometimes, a default app may become disabled by accident or even by other apps. To ensure that the system’s default apps are working as intended, follow the steps below:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap More settings (three-dot) icon at the upper right.
  4. Tap Reset app preferences.

Delete BadgeProvider app data

Another way to fix notification issues in Android is to ensure that a particular app called BadgeProvider is working normally. BadgeProvider manages notifications in Android and it’s usually the culprit for many notification bugs that are being sent our way. Since there’s no way to know if your phone’s BadgeProvider app is working or not, it’s best if you simply turn it back to its default state. Here’s how it’s done:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your S9 and check for the problem.

Reset all settings

This procedure is separate from the previous one as it covers all settings of your Android device and not just the apps. To do this, follow the steps below:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Factory reset

You should consider doing a Factory reset if not one of the suggestions above won’t work. Refer to the steps above on how to perform it. Don’t forget to create a copy of your personal data before hand.

Problem #3: What to do if Galaxy S9 Plus wireless charging option disappeared

This past weekend, we bought an S9 Plus. I currently have an S9 I got in May. We also have an S7 & S8 in the house. I bought a Qi wireless charger from Costco, which has been working on all our devices. Except we can’t get the new S9 Plus to charge on it. Nor can we enable wireless charging on it, as that feature has disappeared from the menu. Literally. Any clue how to get the darn thing to wirelessly charge?

Solution: Both the Galaxy S9 and S9 Plus are wireless charging capable devices so it doesn’t make any sense why there’s no such option under Settings. If this has always been the case after you first unboxed this particular S9 Plus, you should consider having it replaced.

If you were able to charge it wirelessly before but then such capability disappeared after some time, try to restart it to Safe Mode. This will allow you to see if a third party app is behind this issue. Here are the steps to do that:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Check for wireless charging option under Settings > Device maintenance > Battery.

If wireless charging returns under Settings when your S9 Plus is on safe mode, you can bet one of the apps is involved. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S9 is still problematic, repeat steps 1-4.

Remember, wireless charging is an integral part of the Galaxy S9 Plus design. It just won’t go away on its own. Since there’s no official statement from Samsung about this feature being removed from any S9 Plus around the world, your issue must be unique to your device. To return your device’s default settings, you must do a factory reset if nothing works, or if nothing changes when your phone is on safe mode.

Problem #4: How to fix Galaxy S9 SD card issue: photos become corrupted and showing grey bar

Hi. I have a galaxy S9. i had bought a micro sd card to store pics and videos because i don’t have enough storage on the phone. I had no trouble transferring my pics over. Then i set my phone so that all pictures and videos taken will be saved on the micro sd card automatically instead of internal storage. After a while i noticed my pics started to get corrupted. When i would open an image there would be a large grey bar going through it. But when i looked at the thumbnail of the same pic it was fine. Eventually it got worse and even the thumbnails would have the grey bar on it. So i transferred my pics back onto the internal storage. I formatted the micro sd card and i tried again. I put a few ‘test ‘ pictures on it and waited a couple of months, checking on them periodically. Everything was fine so i transferred more pics to test it out and within a couple of weeks i noticed a picture got corrupted. So what should i do? Get another micro sd card? Format it on my phone? Is it my phone and not the card? Please help.

Solution: We don’t think this is an SD card issue because if it is, either your photos become corrupted right away or not at all. If photos transferred to the SD card works fine initially, the cause of the problem must be coming from the phone. We suggest that you factory reset your phone instead to remove any possible bug causing this problem.

It’s also possible that one of your apps may be behind this issue. If the problem occured after installing a particular app, or after wiping the phone thru factory reset, you should focus your troubleshooting finding which of your apps is the root cause. Start by uninstalling any app that can modify camera behaviors or access and edit photos. Since only you knows your apps, resolving this issue lies solely on you.

It won’t hurt if you can replace the SIM card too. Remember, we can only speculate on this matter. We haven’t encountered this issue anywhere before so there may be a unique bug in your system causing it.

How to fix a Galaxy S9 that randomly reboots after installing an update

There has been a surge in #GalaxyS9 troubles recently so here’s another troubleshooting article. Like in previous posts, cases mentioned below are taken from users who contacted us directly. We hope you’ll find this post helpful for you.

Problem #1: How to network unlock a Galaxy S9 Plus

Hi. I ordered my Unlocked Samsung Galaxy S9 Plus from Samsung.com on April this year. Everything is fine, but I’m not able to make or receive a call since I bought until now. I switched 3 Carriers, brought my phone to Samsung care store to check it out, spending time with all my Carriers to get help with my issue. But my phone still gets the same issue. I just learned from Samsung technical support my phone was locked by US Cellular. I called Samsung, US Cellular and my current carrier T-mobile to unlock it, none of them want to do it. I saw on You tube showed how to unlock phone by paying UnlockRiver.com, so they can give the unlock numbers to unlock my phone. My question is, if I unlock my phone by the way on YouTube, can my phone able to call or receive a phone call? Thanks.

Solution: Carrier-branded devices like the one you have is originally built to work for a particular carrier.  Unlocking your phone does not right away means your phone will be able to use messaging and other network services of the current network you’re in. There are other factors to consider in order to make your device work with another network.

A network unlock code works by modifying some settings on your phone so its default network configuration are changed. This may or may not work. In general, a carrier will only unlock their device once all your obligations to them have been fulfilled. If you have outstanding balance with a carrier, they will demand that you settle it first before they can unlock your phone.

Even if you’ve already fulfilled all obligations and the phone has been network unlocked already, there are other reasons why your phone may not work when used in another network. There’s the factor of hardware incompatibility at play. Not all carriers operate in the same band frequency so phones built for them by Samsung also has specific radios. If the radio in your phone is not compatible with the current frequency of your carrier, your phone won’t be able to work even if it’s been network unlocked successfully. Try to do some research by knowing your device’s radio frequencies and comparing them to the frequency bands of your carrier in your area.

Normally, only carriers are allowed to unlock their devices but there are many third party shops both online and offline that can do the job. Be sure to dig deeper into the company that you want to get help from to see if they offer reputable service. Some of them can’t do anything if you have a CDMA device so don’t waste your money asking for unlock codes from these firms.

If you have a GSM device, unlocking is relatively easy and will most likely allow you to use your current carrier’s network services. Before you pay for an unlock code, be sure to contact your network operator to ask if your phone is compatible. Remember, getting an unlock code will not magically remove restrictions on your phone or make it compatible. Working closely with your carrier is necessary so you get accurate, first hand information.

Problem #2: How to fix a Galaxy S9 that randomly reboots after installing an update

I just got a Samsung s9 and when I connected to wifi it updated the software. Now it’s turning off and on and when i try to do a hard reset it gives me this message “security error: this phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/ return for this issue may have additional cost. ” the phone was bnib this afternoon, is there anything I can do?

Solution: Is this a brandnew Galaxy S9? If it is, don’t waste your time by fixing the issue on your own. We suggest that you demand for a replacement to save you from hassles.

If the device is pre-owned or previously used, we can’t think of a reason why an OTA (over-the-air) update will lead to this situation. We assume of course that you update the device normally and not via Odin. If the error occured after an OTA update from your carrier, make sure to contact them so they can create a ticket about the issue.

In some rare cases, normal updates may lead to boot loop or random shut downs. If you did not tamper with the software in any way and the only different thing done was to install an OTA update, factory reset may help. Try booting the device to Recovery Mode and factory reset it. Here’s how:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If factory reset will help, work with your mobile operator to figure out what went wrong with their new firmware update.

Problem #3: Galaxy S9 can’t make a call or call keeps dropping

I have recently purchased a dual sim from Kogan Australia and moved from Virgin mobile (which no longer operates in Australia) to optus (Virgin used the optus network so I thought there would be no issues). I previously had a samsung s7, great phone. I am in a capital city however now when I am in my car either through bluetooth or when the car is stopped I cannot make a call or it drops out, hangs like its trying to connect and over 5  km, will ring and then nothing or doesn’t connect at all. It’ the same when I receive a call I go to answer and it just hangs and doesn’t connect. Also I use the Waze app (Navigation) which also worked great on the Samsung S7, it keeps dropping out in the location etc. I have called Samsung 3 times and Optus twice, they say see the supplier Kogan?

Solution: The reason why Samsung or your carrier refers you to the retailer is to get a replacement, which is a more efficient option to resolve the issue than do some basic, unguaranteed troubleshooting. There’s no direct way to know why your S9 works this way so Samsung or your carrier wants to save your time and effort by getting the device replaced right away. Before you do that though, we suggest that you try two simple troubleshooting — reset network settings and factory reset.

How to reset your S9 network settings:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset network settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

How to factory reset your Galaxy S9

Refer to the steps above.

If both troubleshooting steps won’t make any difference, go ahead and get the phone replaced.

Problem #4: Galaxy S9 won’t detect SD card

My Galaxy S9 suddenly will not recognize my SD card at all. It did this once a few months ago when it got too hot and all I did was turn off the phone to cool it down for about an hour then turned it back on and my card was again recognized. This time out of the blue it happened when my phone had not been used in a few hours and was recently charged. It is in a case so I am pretty sure no dirt got in where the card is located. Please help! Not sure of Android version.

Solution: There are two general reasons for this problem — either it’s an issue with your SD card, or there’s a bug in your phone. To know which one is easy. Here’s what you need to do:

  1. Reformat your SD card using your S9,
  2. Restart your S9 and check for the problem.
  3. If everything works normally, then you’re probably good to go.
  4. If your S9 can’t read the SD card after it’s been reformatted, get another SD card. This will help you tell if the issue is phone-related or not.
  5. If your S9 detects the second SD card and can use it normally, then the first SD card must be defective. Otherwise, you should have a phone issue.
  6. If you think it’s a phone issue, do a factory reset and see what happens. Factory reset should clear the software of bugs.

Problem #1: What to do if your Galaxy S9 won’t detect your SD card anymore

Hi, I purchased a Samsung Galaxy S9 three months ago. About a 4 days ago, I tapped on Bixby to register it. Well, 2 days ago, I was at home listening to music from my phone (my songs are saved on an sd card). I had my phone plugged into a external speaker too. Now, I cannot access my songs, pictures, nothing.  Phone keeps giving me different error messages such as sd card error rewrite, card not supported, card not found. I tried inserting my card into two computers and nothing comes up, not even the card itself. It’s like my card is now a ghost. I did not rewrite it because I have photos and songs on it. The card will not show up.  I’ve tried the steps you have listed on your site. — Erica

Solution: Hi Erica. There’s no perfect electronic storage medium. That’s one sad fact when it comes to digital storage. If multiple devices no longer recognizes your SD card or read the contents in it, it must have become corrupted or damaged. That two computers are not able to access your music and photos is a clear indicator that this storage medium is no longer working properly or at all. Unfortunately, there’s no way reverse whatever occured that caused your card to become unreadable. At most, you can let a professional try to recover your files but even that is not a guarantee because a computer won’t even recognize your SD card at all. In regular data recovery scenarios, there are some minimum requirements that must be met before the actual recovery of files is attempted. One such requirements is that a computer must still be able to read or recognize (detect) the card. Data recovery is hard and not guaranteed. If you think those files are worth spending a few hundred dollars, you can use Google to find services of companies that specializes in data recovery.

Try data recovery services

Data recovery needs technical expertise and right tools to work so it can be expensive. If money is not an issue and you really need to those files, do some research using Google. While there can be many reputable companies that you can try, there are also tons of scammers that may offer similar services, so use judgement when picking one. We don’t specialize in this field and we haven’t tried using any such services so there’s no particular company that we can recommend. Based on how you describe your situation though, it looks like there’s a very slim chance that you can recover your files. We won’t discourage you any further but keep in mind that once an SD card becomes corrupted, that’s for good.

While looking for a way to recover those files, try to avoid using your SD card. Remove or disconnect it from your phone or computer to avoid overwriting possible working sectors at this time.

Format your SD card

If you think you can just forget your files, try to reformat your SD card using your S9 to see if it will continue to work at this time. Here’s how:

  1. Open Settings app.
  2. Tap Device maintenance.
  3. Tap Storage.
  4. Tap SD card.
  5. Tap More settings at the upper right (three-dot icon).
  6. Select Storage settings.
  7. Tap SD card.
  8. Tap Format.

Prevent data loss

In the future, always make it a habit of backing up irreplaceable files or photos to at least two devices. For example, if you have memories in photos that you can’t afford to lose, try to back them up in a cloud service like Dropbox (or any other cloud services) and/or to your computer. You can also use a flash drive, a portable hard drive, or another SD card. Remember, any electronic storage device can fail at any time and there’s often no way to fix them effectively, just like what we’re saying in your case above. While there’s little to nothing that you can do for your current problem, you can prevent losing important data by doing a common sense action — creating a backup.

Why do SD cards fail?

SD cards can fail due to a number of possible reasons. Below are the common causes why an SD card may stop working unexpectedly:

File corruption

A corrupted file means that said file has lost the necessary coding markers and characteristics for it to become readable by a device like your phone. Such situation may be due to physical defect of the SD card, an operating system glitch, or a firmware bug. Some corrupted files can be “repaired” by special tools. Such software tools are usually proprietary and needs a trained technician to operate. Low level recovery tools may also allow file repair as long as the SD card itself is working. If your SD card was not physically damaged or broken and the files can still be fixed, there’s a chance you’ll be able to recover them. Knowing what the real reason for your SD card failure though is very difficult.

Physical damage

Due to its size, SD cards are vulnerable to physical damage if not taken care of properly. Aside from the fact that it can break pretty easily, an SD card can also physically fail if subjected to electrostatic discharge or water exposure. To minimize the chance of causing physical damage to your SD card, you should treat it like your phone.

Loss of good sectors

The more you use the SD card, the higher the chance of it accumulating bad sectors. This means that the aging SD cards can potentially develop problematic areas to hold bits and bytes.

This is a natural phase for storage devices though and today’s SD cards can continue working for several years under normal circumstances.

Improper removal of SD card

Not many smartphone users realize that they can damage their SD card or cause file corruption by not unmounting properly. In fact, this is one of the most common reasons why SD cards or files stored in them may become inaccessible. Before you remove an SD card from a running Galaxy S9, you want to make sure that you unmount it. Unmounting means that you’re telling the operating system to stop whatever activity it is doing with the card, whether reading or writing (saving) on it. Disconnecting the SD card from your S9 while it’s trying to save something to it can lead to errors which oftentimes causes file corruption. To prevent this from happening, you must unmount the SD card before physically removing it.

To unmount an SD card from your Galaxy S9:

  1. Open Settings app.
  2. Tap Device maintenance.
  3. Tap Storage.
  4. Tap SD card.
  5. Tap More settings at the upper right (three-dot icon).
  6. Select Storage settings.
  7. Tap SD card.
  8. Tap UNMOUNT at the bottom.

If you find unmounting via Settings too cumbersome, you can simply turn the phone off, then remove the SD card.

Virus or malware

Sometimes, virus or malware designed to target a device’s storage device may also cause an SD card malfunction or file corruption. Make sure that you observe the standard malware prevention tips like making sure your device regularly update its apps and operating system, avoiding suspicious websites, not clicking on booby-trapped links, or installing bad apps from suspicious developers.

Manufacturing defects

Like other electronic devices, some SD cards may come with manufacturing defect/s. Some defects may show sooner than others. There’s no telling what specific defect may occur in an SD card but to minimize an unexpected data loss from this factor, we suggest that you buy brands with good reputations. There are many excellent SD card brands out there so it’s up to you which one to get. Samsung also manufactures its own line of SD cards so we suggest that you use them to greatly decrease the chances of incompatibility and manufacturing defects.

Problem #2: How to recover files from a stolen Galaxy S9

My Galaxy S9 was stolen and I’m trying to recover my media files as well as lock my phone so the thief cannot use my phone. It was stolen yesterday so it might be too late but I thought I had my anti theft already set up as well as a backup for my files and I can’t access either of those things…what can I do?! This man stole so much more from me when he took my phone! All of my babies pictures and videos were on my phone from the time she was born and she is 3. I just want my files in all honesty! — Aminah Hines

Solution: Hi Aminah. The Anti-theft feature on your Galaxy S9 Plus should be activated if you’ve successfully added a Google account or ID before and if you enabled one of the following screen lock protections:

  • Pattern
  • PIN,
  • Password
  • Fingerprint
  • Iris lock

If you’ve used any Google services on your phone like Play Store before it was stolen, you can rest assured that the thief won’t be able to access your data. However, all the videos and photos that were saved locally, which means they were not saved elsewhere outside your phone, are gone for good. Apps like Dropbox, Google Photos, or even the standard Samsung app can be configured to upload photos automatically. Unless you enabled an app to automatically upload your photos to the cloud before your phone was stolen, there’s no way for you to recover your files remotely.
