Micro SD Card Handling - LG V20 Questions & Answers

Anyone know what the phone's behavior will be when I insert an SD Card? Usually I would want to format the card with the phone if I'm going to keep it in there 100% of the time. But right now, I'll be removing it now and then.
Can I just plug it in, and the phone will recognize the directories that I already have on the card if the card was originally formatted in Windows? Obviously I can back up my SD Card first, format it on the phone, and move my stuff back to the card after.. Just wondering what the best way to go about this is. I haven't had a phone with an SD Card slot since my GSIII.

As long as the card is exFAT format it shouldn't be an issue. It will detect any media in it and display it accordingly (well should).
If the card is NTFS formatted, it won't work

if it a fat32 memory card you can cross-swap as much you want. You do not need to format on the phone... I never really did ...

I pulled my SD card out of the Note 7 and dropped it into the V20. No problems.

Cool. Thanks!

Will the card once inserted be encrypted or can it remain unencrypted in the v20 ?

[Q] Installed MicroSD Card Not Detected

Hi Everyone
Any ideas why my Moto X Play would not even see my brand new MicroSD Card?
It's 128GB and so far I've tried it formatted as both EXFAT and FAT32 and no dice! It just doesn't even see the card.
Anyone have a guess at what gives?
**Edit**
So I've tried multiple sizes and brands of SD cards and none of them seem to be detected by android. Also tried resetting the device and no dice. Looks like my card reader may be borked.
** Edit 2**
I ended up having to return my device, as the card reader was pooched. The store simply did an over the counter exchange.
Can't see any reason why it wouldn't work. Maybe the card isn't mounted properly (in the wrong position) or as you said, you may have a faulty card reader on your phone.
I may be suffering the same issue. Have you been able to achieve anything regarding this?
I ended up having to return mine. The SD card reader was dead as I had suspected.
if you can format the sd card that means your phone see's the card and you can choose weather if you want to format as internal or external i like it internal but you have to get a faster card for sure and if you switching card from 16g to 32g....ect you have to forget the latter card then you can restore all your files. it worked for me.

Question on SD Card usage

I remember reading a while back that the SD card might have to be formatted in some weird way to do something.
Is it possible to just use a fat32/exfat formatted card in the phone as pure storage such that it's still 100% readable on a computer?

SD card not working

Hello, I'm new here.
I'm using Moto X Style Indian version with Android Marshmallow from last 5 months. I'm using "SANDISK ULTRA microSD UHS-I CARD" with format as internal storage without any problem, but now suddenly a notification show up that "Insert your SD card", I even didn't remove my card since I put it once. I tried to insert my SD card to HTC phone, saying "Damaged SD card" with only option for format it. (I'm not able to take screenshots or click any pic)(SD card is still in my moto x style but in setting it shows "Not Inserted".)

Welcome to the world of adopted storage...
Try to power off the device, remove the card and reinsert it, then power back up. If that fails, either the card has failed or the encryption key has gotten corrupted or "lost". There isn't a lot you can do to save or resurrect it if your device doesn't see the card and unencrypt the data.
When a card is adopted as internal storage, it is encrypted and uses the ext4 filesystem, it will only work in the same device with the same key and cannot be read in any other device without formatting it back to FAT32 and wiping out all the data. There is some information here about reading the data with a Linux computer, if you have the appropriate card reader and can access the encryption key on the device.
Thanks for your reply @acejavelin,
I tried everything turn my phone off, eject card then reinsert it, still same error. Now what to do? Will I format my card with FAT32 by attach my card with PC? I know my data will not save... but I have no option.

Yes... Reformat it in a PC or in another device. Personally, I would not reuse the card, especially as adopted storage, since it can no longer be trusted.

Ok, I will also not use this card again with adopted storage. Thanks for your suggestion @acejavelin .
Seems my problem will be solved , but all my data will loss :crying:
Sounds like the problem is with your phone's SD card reader, not with the card itself. Other computers / phones will tell you the SD card is damaged/corrupted because they cannot read it (the card is encrypted), but that doesn't mean the card is actually damaged or corrupted.
You won't be able to extract your data from it unless you can get it to read the card again. I would try popping out the sim /sd card tray and shoving it back in many times, to see if eventually it will read (mine takes 2-3 tries before it will read)
If you can't get it to work you may need to contact Moto support to get a replacement under warranty (assuming you haven't unlocked the bootloader / voided the warranty)
Definitely try another card though if you have access to one, just to check and see if it will read a different card.

SD Card problems

I have recently purchased a SanDisk Extreme Micro SD 64gb SD card for my S7 Edge.
On Android 6.0 I had various issues writing to it. Since the Nougat upgrade it has worked faultlessly until this morning. The phone will not detect it at all.
Is there a compatibility issue with this card or is it simply faulty ?
Sounds like the issue could be the card. It's happened to me with the same SD card.
Connect the sd card to a computer using a SD card reader.
Backup all your data.
Put the SD card in the phone and choose to format it.
Connect SD card to computer and put all files back on the SD card.
Put SD card back in the phone and should work as normal.
That worked for me.

SD Card Format issue

I have a samsung 256GB Evo card, and i just installed a new rom this rom: https://forum.xda-developers.com/v20/development/rom-natf-1-00-test-5-debloated-stock-t3509750
So i seen the little sd icon and i tap on it and it said my sd card is corrupted and needs to be formated. so i put into my computer and copied all the data before i wiped. I formated the SD on windows for extfat and put the card into my v20 and boot it up and i got the same error message. so i went ahead and formatted it using the phone. Plugged the card back into my computer and it shows it was formatted in fat32 format. which is strange. anyway i reformatted it again in windows and put the card back in the phone and got the same thing.
Anyone using this card or phone can verify if your v20 formats the card in fat32 format and let me know. if not anyway to fix it?
