I can verify that the Samsung Electronics 32GB Micro SDHC Class 6 (it's blue and white) Works with mine. It's honestly true guys, just grab a lower class speed or rather one that isn't UHS-1 some people are getting lucky with the Ultras but it's still something worth keeping in mind.
[Moto G Q&A, Help & Troubleshooting] starfire:
I've tried a Kingston 32GB Class 10 and that fails to work also, works fine in all my older phones and my PC.

Only card I can get to work is a very old 2GB card!

Can everyone please get onto Motorola Live Chat and tell them, they deny there is any problem but clearly there are serious compatibility problems with the phone.

The more people that tell them hopefully something might get done...

Hello,

I think XT1040 is 8 GB; and XT1045 is 16 GB.

Has anyone had luck with larger/faster cards after going throught RMA with Moto directly? Just purchased one through Amazon (sold by Moto) tried 3 cards, 2x 32GB Ultra Sandisk and 1x 64 GB PNY Class 10, with the eject issue but an old 8GB Samsung low class card works fine. I spoke to Moto's support and they are doing an Advance RMA for the device, great support btw geared toward customer service. I'll chime in when I get my RMA.....

I have a Moto G LTE also. I tested a 64 GB Sandisk Ultra I got in 2012 and one I ordered 4 days ago and both would not work. I just ordered a G.Skill 32GB Micro SDHC Flash Memory Card (FF-TSDG32GN-C6) off Amazon for $13, I will let everyone know how it goes when I get it.

This is the one I use..works flawlessly in my XT1045 internal slot or as a MicroSDcard in the USB/Charge port..runs MP4 video perfectly..even with another card mounted also..I have (4) of these "Team" cards (1) 64GB, (3) 32GB..just ordered another 64GB, 10 minutes ago..I formatted them with WinXP FAT32 and have had excellent performance for more than one year now..

Have the same problem here, I got a SanDisk 32GB SDHC Class 10 and it randomly says it's removed or damaged, it works in my laptop though and even tried formatting again.

So I just tried the SD card that was in my raspberry pi (Samsung 8GB class 4) and it's working perfectly on that.

Hello,

Just to note official specifications cites up to 32 GB (http://www.motorola.com/us/moto-g-pdp-1/Moto-G/moto-g-pdp.html). So you don't must rely besides this.

Got my replacement LTE from Motorola and my PNY 64gb class 10 ultra 1 seems to be working well. Been about 4 hours since setup but no card ejects with about 4gb written to the card.
[Moto G Q&A, Help & Troubleshooting] ram11:
So your old phone wouldn't accept the same card but the new one does? it seems strange as everyone was of the notion that their firmware has some problems to do with a few class 10 cards
[Moto G Q&A, Help & Troubleshooting] derekjd:
Correct, don't know exactly why but I do know support wasn't surprised by the issue. They were more than happy to advance RMA.
[Moto G Q&A, Help & Troubleshooting] huali:
Card arrived today. It came formatted in FAT32 but when I put it into my phone it reported it being damaged. After formatting the card through android it's working well and I've experienced no problems so far.

Ran the card through CrystalDiskMark and the card performs better than my previous Samsung UHS-1 card.
[Moto G Q&A, Help & Troubleshooting] spaedi:
I too just bought 2 moto g 4G's on sale for $240 AUD to replace our samsung galaxy S3s...

Went to swap out the sandisk ultra micro SD neither card works in either moto g.

As well as the vibration motor sounds clunky and cheap, thinking about returning the handsets, not impressed.

Rang motorola support, guy says they have tested on their end moto g 4G with same micro SD card with no problems and that I probably have a faulty micro SD card....

Funny as both micro SD cards don't work in 2 different moto g handsets, there is clearly a problem with class 10 cards working with this handset....

I'm still running a class 10 64gb card with no issues here. I'm really wondering if there was an issue with the SD reader on first run units.

That's what my initial investigation concurred
[Moto G Q&A, Help & Troubleshooting] jc0v:
Add me to the list of people suffering from this issue. I have tried two Sandisk Mobile Ultra cards(32gb and 64gb) and neither work. Both mount but when I try to write to them I get "SD card was removed unexpectedly". I believe these cards are both class 6 too so that conflicts with what has been said about class 6 working. I spoke to Motorola tech support yesterday and they say they are looking in to this urgently. Very frustrating.
[Moto G Q&A, Help & Troubleshooting] SbM_:
The class of the card is written on it, in an incomplete circle. As far as I can see from pictures on the net, Mobile Ultra cards are class 10 AND UHS-1, which seem to cause problems.
[Moto G Q&A, Help & Troubleshooting] jc0v:
I see that they do now but I have had these cards for a couple of years and they don't have the class written on them. An old order email I had said that they were class 6 which is why I said that. I should also have said that these two cards work fine on my tablet and S3.
[Moto G Q&A, Help & Troubleshooting] SteveJC1:
Same Problem

I got my Moto G 4G today and have exactly the same problem with my old SanDisk 32GB Mobile Ultra Micro SD Card - Class 10 UHS-1 . The card worked fine in my old Razr i and in my PC. No amount of reformatting or remounting would solve the problem in the new phone. Then I popped it back in my old Razr i and it worked fine in that.

I had an old 2GB class 4 card lying about and put that into the Moto G - and, what do you know, it works fine.

I ordered a replacement card from Amazon before reading this thread and perhaps made a mistake by going for a Samsung 32GB Pro CLASS 10 UHS-I.

Does anyone know if this will work, please?
[Moto G Q&A, Help & Troubleshooting] SbM_:
Might not. I would stay away from class 10 / UHS-1 cards.

Just purchased 2 Moto G 4G's from Phones 4u. My 2 year old SanDisk Ultra 32 GB is not recognised in either phone but it works perfectly in my old Nokia 520 and Huawei Ascend G300. My wife's 2 year old Kingston 8 GB card works in both new phones. I am returning both phones tomorrow - I wish that I had read this thread before purchasing the phones!!!
[Moto G Q&A, Help & Troubleshooting] Triggeh:
Return/swap the sdcard not the phone, my 32gb one works fine and as far as i can tell sd card speeds aren't much different with the more expensive models and on transfers your mainly limited to the interface.
[Moto G Q&A, Help & Troubleshooting] derekjd:
I would swap the phone, shouldn't need to buy a slower card for a new phone. May actually bottleneck data transfer down the road.
[Moto G Q&A, Help & Troubleshooting] Triggeh:
How is it going to bottleneck transfers when it will still be using usb 2.0?
[Moto G Q&A, Help & Troubleshooting] derekjd:
I would think data written directly to the card from the phone is faster than 2.0, but maybe I'm wrong.
[Moto G Q&A, Help & Troubleshooting] Triggeh:
You said transfer so I thought you meant pc > phone transfers, regardless I don't see much of a need for a high speed sdcards until we get faster interfaces on phones. Unless your trying to read/write lossless videos or something large that cant fit on your internal playback even on a 9gb 1080p file downscaled to 720 worked just fine for me.

Hello,

My card is: UHS-I SanDisk Ultra microSD HD 32 GB, product SDSDQUA-032G (http://www.sandisk.com.br/products/memory-cards/microsd/ultra-class10-for-android/?capacity=32GB)

It works on Samsung Galaxy SIII mini GT-I8190L, but doesn't it on Moto G 4G/LTE XT1040.
[Moto G Q&A, Help & Troubleshooting] SteveJC1:
It Is A Known Problem

I found a thread over on the Motorola Community about this. Unfortunately as a new member I'm not able to post a link to it here (stupid rule if you ask me). Just search the community for Moto G LTE SD Card Issues.

It is clear this is a known issue at least with 32GB class 10 cards. People are listing the specific cards with which they've had problems.

I've included mine.

The forum's moderator is saying there will be a software fix from Motorola.

Let's hope it's soon!
[Moto G Q&A, Help & Troubleshooting] zadro:
PS I thought that I would buy a slow 16 GB card to resolve the problem. Guess what Verbatim 16 GB class 4 cards dont work either - same error message - broken card. Phones 4u may let me pay another £100 for a couple of Sony Xperia M's if head office allow!!! I really like the Moto G but I can not see a software fix working, it must be a Hardware issue. My old Ascend g300 was promised all sorts of fixes but none worked well and the phone was quickly replaced by the G330. I see the same happening again. I just want my money back.

[Moto G Q&A, Help & Troubleshooting] bhavin192:
After Reading All 6 pages

I think the issue is with kernel (or ROM) of phone and not hardware

also moto e has problems with other fs like ext2,3,4 :( whereas android is linux based still mounted SD with ext2,3,4 doesn't work but some internal partitions are ext4 :-\

AFAIK The card must work with people who have unlocked kernel &/ Custom ROM

I purchased 2 phones and 2 of the samsung 32 gb class 10 cards from amazon.

one of the 2 phones had the problem, didn't matter which sd card it was, it would unmount it.

the other phone worked fine with either of the sd cards.

Given that many people have had this problem and it does not seem to be related to

the SD card itself,

the problem might be fixable in software, but I think there is a hardware issue.

By this i mean that the hardware might be marginal with a timing issue or

spurious interrupts that can

be overcome/masked with a software update/tweak to the driver.

Heh, I've been on xda for almost a decade. I know my way around SD tech. I formatted it in the PC before sticking it in the phone, in FAT32. The phone still wanted to format it. I let it do so. When I plugged the phone into a USB 2.0 port on my desktop PC it unmounted the card. The card works fine in LG E970, HTC M8, and several computers. There isn't anything wrong with Samsung SD cards. They make more NAND flash than any other company in the world. I had massive issues with Sandisk 64GB cards when they came out, and switched to a Samsung 64GB card. It still works fine. I'm running a 128GB SanDisk in my M8 with zero problems. If you go visit the Motorola forum thread about this problem you'll see that they are aware of it and a fix is contained in the Android 4.4.4 update. I appreciate your trying to help but trying to blame the card for a problem that a large percentage of Moto G LTE users have experienced isn't the best form.

You may be OK with no name flash but that doesn't work for me seeing as how this particular phone is already on a plane to where it needs to be. When I give tech items to people that are not nerds I tend not to give them dodgy stuff like 3rd rate nand. You're almost coming off like a cheap nand vendor. All I asked you was if you've been so knowledgeable about moto then perhaps you could provide just a shred of evidence beyond the fact that your particular cards work in support of your argument that only cheap/slow cards work. Perhaps some of the devices are just defective. This seems reasonable.

Hi,

My parents got two Moto G LTE (XT1039, distributed in Poland). They got free Kingstons 16GB class 10 with their phones, but those doesn't work. Phones are showing card is broken...

I was testing GoodRam 16GB class 10 card (sold in marmot colour package like that http://www.allegro.cartexim.pl/allegro/GOOD164.jpg) and that was not working as well.

On the other hand, I've checked with my GoodRam 32 GB class 10 card (bought few mounths before, looks different than this 16GB one - has got inscriptions in landscape) and it is working fine in both Moto Gs'.

Old 2GB Samsung cards are workingg fine as well.

I saw that this issues is present in the Moto E even, so i think that can be a software problem.

If this was a sofware issue so both phone should be with same problem, but it is not like that. I don't know if i have to return the phone back and ask a refund, because i don't understand if it's an hardware problem (in this case some device are really defected) or a software ones.

Do you think this is a software issue, not hardware?

same cards, same phone, different results...this seems an hardware issue to me!
[Moto G Q&A, Help & Troubleshooting] isri:
In my parents case both didn't work with the same cards (I don't mind the same models but the same piece of hardware). I've bought to test new GoodRam 32 GB class 10 card and didn't work in Moto, but it looks different than my old one - looks different, UHS 1 is additionally written on that and also didn't work, but my old one works fine.

My friend told me that his wife has some LG.. something phone and with some cards it makes hot and has battery drain. With old cards it works fine.

Maybe it's some hardware issue but I believe it would be more random like today it's working, tomorrow it will not or specific card is working on one phone on second doesn't. Now it looks more like new cars didn't work while older works fine.

I'm not expert in that case - but maybe some technology or the way cards are made was changed. I believe most of them came from one factory but at the end has different logos put on, and there are probably much more stuff connected with mounting/running cards than capacity and class, like voltage, etc.

On Polish Wikipedia I've found such info

It means that SDHC are usually compatibile with only with SD v 2.0 reader but not always. Some v 1.1 reader can read SDHC cards if operating system can work with v 2 SD cards (like in Acer n300 and some PDAs).

It could be simillar situtation so it could be fixed with some software modification :)
