LG G7 ThinQ Unsupported SD Card Error

Problem: My device has been showing a “Unsupported SD Card” message in my notifications for about a month.  My device was running flawless up until this occurred. quickly, I am not sure about the android version I am running.  The device is an Android LG G7 and I had it pre ordered. Maybe that information will keep us both on the right track if you guys send the troubleshooting information back to me.  Basically, device running fine, I started receiving these messages in the notifications drop down. When I tap on the message I was hoping it would take me to a setting that could possibly be set incorrectly, or maybe an advanced setting that I could just troubleshoot myself.  Unfortunately, tapping on the message does nothing.

I have tried the following…


Power off/back on after 10 sec.

Removing the SD card with the device powered down, reinserting and powered up.

Plugging into a pc to see if SD card is visible (which since this message started showing, it is not)

The last couple of weeks,  the message does not appear any longer, yet I still do not have a mounted SD card.   

Before I use useless apps to check my SD card,  I was hoping to get some feedback from you guys.  If you could please respond, possibly send me some type of sequence of troubleshooting I could try before having to take it to the T Mobile store (which from my experience is a waste of time).  Please let me know.

Solution: The first thing you will need to do in this case is to eliminate the possibility of a faulty microSD card that’s causing the problem. To do this just replace the card with a new one. If the new card can be detected then the old one is already defective.

In case the new card can’t be detected by the phone and you still get the same error message then it’s time to backup your phone data and do a factory reset. This way you can check if a software glitch is causing the problem. In case the issue still occurs after the reset then the problem might be caused by a faulty hardware component. You will need to bring the phone to a service center and have it checked if this is the case.

LG G7 ThinQ Not Recognizing microSD Card

Problem: Hi.  I believe my new G7 phone has either a bad memory card reader or a software issue that is preventing 64 gig Micro SD cards from being recognized. I have tried 3 different cards. However, these same cards do work in my Daughter’s  phone. Additionally, her own card that works in her phone will not work in my G7. Lastly, I even took my new phone to a local store to see if they could figure out the problem. They also could not get any of the cards to work in my new phone.

I am on a Pre-paid Service which uses Verizon’s towers so I had to get a Verizon Compatible  phone.

Here’s are the steps I took:

  1. I tried my current 64 gig Micro SD Memory Card that I use in my former phone (Galaxy S8). It is not recognized by the new phone I received from you.
  2. I tried a brand new 64 gig Micro SD Memory Card in the new phone I received form you. It does not recognize the card.
  3. My daughter has a Galaxy S8 phone, so I tried my daughter’s 32 gig Micro SD Memory SD Card that she uses in her  phone and that will not show up in my new phone either.
  4. I took the cards in steps  #1 and #2 above and placed them in my daughter’s  phone and the both ARE Recognized by her phone. They work fine.
  5. I drove to a Verizon Dealer, located at BJs Warehouse in Derby, CT.  I spoke with a tech. He tried both my Micro SD card that I was using in my old  phone and the new Micro SD card I just bought. He verified that neither card will show up (recognize) in my New  phone.
  6. He took both cards mentioned in #5, #2 and #1 above, and he WAS ABLE to get them to work in his Galaxy S7 phone.

Do you have any suggestions that might be helpful to me? Thank you!

Solution: It appears that the problem is on the phone side. Try doing a factory reset to eliminate any software related issues that could be causing the problem. Make sure to backup your phone data before doing the reset. If the issue still persists after the reset then you should have your phone fixed at a service center as it looks like the SD card reader of the phone is defective.

LG G7 ThinQ Pictures In MicroSD CArd Have Exclamation Mark

Problem: Hey, i need your help to solve an issue that started to happen yesterday. I have a G7, running Android Oreo I have a Samsung SD Card Evo 64GB. Since yesterday all the photos I had on my SD Card are not viewable. In other words, the files exist but the preview appears a black icon composed by an image symbol and an exclamation point. I used the file viewer and the files are stored where they should be in the SD Card. I executed the media Re.Scan app to try to fix the index, but nothing changed. I copied one of them to my laptop and I cannot see it also (windows 10 tells me that “cannot open this file”). Can you help?

Solution: If your computer can’t read the files in the microSD card then they are most likely corrupted already. The best thing you can do right now is to recover any data that can still be recovered from the microSD card then get a new card for your phone.
