Under Marshmallow, can the entire external SD card be made writable? - Galaxy Tab 4 Q&A, Help & Troubleshooting

Under Marshmallow, can the entire external SD card be made writable? I have a SM-T530NU, installed CM13, and made the external SD into internal storage. I would like to copy stuff onto the device, but it seems I can't do it via USB connection to me PC or via ftp.
I tried setting the external SD up as being used for sharing media, but 6.0.1 assigns a wonky drive ID, and the thing is readable but not writable.
Are there work-arounds for these problems?

Make the external portable, not internal, and everything works like normal. That's been my experience (SM-T530NU on CM13)
Also, completely unrelated, New Englander here, I was absolutely floored the first time I visited the beautiful city of Albuquerque. Such natural beauty is completely absent from my area of the country, I enjoy every second of New Mexico I get to experience (dad's got a lot of business trips there). Not saying there aren't beautiful parts here in the northeast but it's utterly different there. Although your squirrels are kind of funny looking lol

You have to check the forum for your specific device. This forum is for the Samsung Galaxy Tab 4. If there's someone who can answer your question, it's a good bet they're not hanging out on this forum

Ok thankzz

[Q] Storage preference on Stock Rom

I recently obtained my first real Android phone S III after years with Android on HD2 and my biggest question right now is how to make the phone to recognize and use the External SD to store data (for example Music Google Play off-line files)? My internal memory is almost full, but there is almost nothing on the SD card.
Thank you very much for your help and I'm sorry if I make some mistake in posting, this is my first post - although I try to search for the answer before posting.

This is the biggest problem!!! I took out the card and put it in my laptop with adapter and put videos, music and photos!!!
Then reinserted the card. Now I can see and hear thru it! But Samsung must issue an update to correct this flaw!!!!

I don't know if I explained myself good. I would like for the app to store data (mainly multimedia like music, podcasts, etc) on external SD card so there is more space left in the internal memory. Is this possible?

Galaxy S3 exFAT support removed Build BVALF4

Hi Guys and Girls
Just a bit of info for any of those having problems with 32 or 64GB cards in their S3 post upgrade to
Baseband I9300BVLF2
Build IMM76D.I9300BVALF4
Basically after a week of speaking to Orange and then Samsung (Orange even sent me a new handset as they couldn't explain it) I've found out that Samsung in their Wisdom have removed ExFAT support from the new Firmware.
They are apparently looking into it but for now recomend formatting your card to FAT32 as this is still supported.
At work right now so haven't tried it myself but will as soon as I get in and post results (if anyone else can let us know)
What the hell are they thinking?!
This would be a dealbreaker for me. Its the only reason im not using cm10 yet.
We need to get away for this fat32 nonsense with its useless 4gb file size limit.

That'the one they have just released on Kies.
To be fair i though this issue was down to me rooting so will prob now root again now i know it's not that.
The guy at Samsung support said he couldn't understand why either but they have it as an action point to sort out as they were getting a lot of calls about it.

There are later updates so i would check if the problem is still on later firmware .
You can always join XDA Developers and flash latest firmware .

I'm using LG8 and it's fine on there.
Another accidental removal :silly: exFAT is accepted by pretty much everyone to be validly patented by Microsoft, so to ship it in the first place Samsung obviously had a licence.
Would ext4 work? I know it'd be a pain to format to with Windows or Mac, but gets around 4GB file limit.
When connected in MTP mode the phone should do the "translation" so the desktop OS wouldn't need to handle the filesystem (I think, but I could be wrong). Doubt there's much danger of ext* support disappearing.
I just registered to say this but I'm also in the same boat. I noticed that orange had modified the ICS firmware to remove the update so while I was in London I went into the Samsung store in the Olympic park. I told them the situation and they said they could update the firmware there and then, 2 hours later after I left with a phone that no longer supported my 64GB microSD card and my widgets still popped in on the phone.
I was wondering if I could get an opinion on whether I should roll back the firmware by flashing the phone or try and complain to orange and get a new handset (although it's past their grace period and are unlikely to do so). Just to reiterate stay away from the Samsung store in Olympic park, all but one of the staff where extremely un-organised, dim witted and more interested in looting freebies from the store than actually helping me.
I would also consider using a custom ROM but as this is a relatively new device I'm unsure if this would be best suited to getting the best out of my phone.
Any suggestions would be greatly appreciated.
Ok, I'm now on the VLG1 official Orange firmware and I re-formatted my 64GB SanDisk SDXC card as exFAT, put all my stuff back on (including a new .mkv over 4GB just to test) and it now works perfectly in my S3 (the 5.5GB mkv files plays fine, but with no audio although since it's a DTS audio codec used in the movie, I suspect this is a different issue).
So it seems they re-enabled exFAT support in VLG1...
Could someone tell me if exfat works in a S3 with I9300UBLG2?
Well, it does "work", but it's nowhere near reliable.
So far, my experience with exfat has been awful with Sandisk's 64GB SDXC card. There were some serious issues with a lot of music files that weren't visible to the phone. The files were copied ok in there when I used my SD card adapter and the total filesize matched perfectly to the original folder that I copied them from. So, when I inserted that card into my phone, I was suddenly unable see more than 70% of the files. I repeated the copying proccess few times and the result was exactly same every time: same files ended up missing in my phone.
I was also quite surprised when I replugged the card into my sdcard adapter: those same files were now missing from the card in my pc too. The card however did report exactly same amount of available space that it did when I first copied the files. When I tried to copy those missing files again on my card, it asked me whether I would like to overwrite those files? But those files can't be there since none of my devices see them!
After doing some research, I found out that this is actually a known problem, at least with Samsung's phones, and that those files weren't actually missing. They are still there, but something on Sammy's firmware is breaking something with a certain filenames/folder structures and makes them seem like they don't exists at all. At this point I just gave up and reformated my sdcard into fat32 with fat32format (the default Windows format program doesn't format cards with that size as fat32), copied my files again and now my phone was also able to see all my files.
So no, I wouldn't recommend using exfat with Samsung's phones since their implementation seems to be somewhat broken and due to the fact that CM10 wouldn't work with it anyway if I would eventually decide to move on it.

I purchased my S3 because of Exfat support and have used an genuine Sandisk 64GB SDXC card in it for a long time now; I've have had zero problems with missing files, are you sure your adapter isn't faulty?
I know that after upgrading the firmware, Samsung removes/messed with the exfat support. So I'd like to know which firmwares have support to exfat.
The S3 I have is UBLG2 and I'm intended to buy a micro SD 64gb class 10 (or class 6).
No fat32 'cause I have files bigger than 4gb

SD card storage will be going away, get used to it

I was listening to Koush Dutta (developer of ClockworkMod, All Cast, etc.) on All About Android podcast and he talked about why external SD cards are bad and why they're going away. Some of the things he brought out are:
- There's no standard API to access the external SD card in Android. He says that each device does it a little differently and it's a nightmare for developers to work with external SD cards.
- The device is certified by Google before being sold. When an SD card is inserted the user is basically taking a certified device and introducing an uncontrolled storage media. People often buy cheap SD cards that aren't capable of performing up to the level of certification for that device.
- When users buy a slow SD card and it doesn't perform well they complain to the app developer and put a bunch of 1-star reviews on their app. The developer is frustrated because it's a situation outside of their control and they're getting slammed for it.
Basically, he said, both the device manufacturers, Google, and app developers dislike the external SD card. Koush predicted that external SD cards will eventually go away completely.
Well why don't we just start a SDCard certification for google and throw a G stamp on the packages to let us know they can be used on devices?
There are solutions to this problem.

Koush compared the SD card to the DVD/CD drive. People hesitated to buy ultrabook PCs at first because they had optical drive. Many laptops no longer have a optical drive. He said it would just be a matter of time before external SD cards will also go away.
Of course a developer is going to go for the simplest and best solution for them. They aren't being charged $50-100 per move between 16<>32<>64GB the way we are. Nor do they get a monthly bill from their wireless carrier for data when stuff's stored in the cloud. If Google wasn't so hell bent on pushing people toward the(ir) cloud I'd imagine they'd be able to come up with a process and standard to accommodate removable storage. Then, if manufacturers and third party devs followed that standard they wouldn't be getting complaints from users. Those that didn't follow the standard would deserve the complaints they got. Technology is a tough and complex business. Somehow on the PC side Apple and MS have figured out how to manage third party peripherals so if Google had the will I'd assume they'd find the way. Taking something of value away from the consumer in the name of "it's better for them;" especially when the cost and loss of convenience is so great is frankly BS.
P.S. - Removable Android storage has been around since 2010 when the SGS1/i9000 was released. Why is it suddenly a problem? Especially one that can't be addressed by a company with Google's resources?
Barry,
You bring up good points. Here's how'd I'd answer this...
On a PC it's different. Removable storage is generally used for transfer of data. People don't put apps on an external SD card and run them from there. They use an internal disk drive for apps. Why? Because they have a lot of internal disk. Yes, external storage is used for storing movies.
On a phone or tablet people are trying to use an external SD card as an extension of the internal storage. It's not meant to be used as such. It's a transfer medium or video storage medium. And, that's exactly the direction it's going.
I don't think that cloud services are driving this decision. After all, cloud connections are considerably slower than an SD card. And, if one wants to connect external data for file transfers there will still be OTG connections. I think that this will force manufacturers to increase internal memory. Look for 128Gig and 256Gig internal memory in the future. Once that happens people will forget about external SD cards.

CD and DVD drives are a pain to write to. Our laptops still have USB ports and everyone I know use Flash drives and External HDD to move files around.
Until
1. Internet is extremely fast almost anywhere you go.
2. Internet is unlimited again.
3. Internet is like how it is in Japan
I don't see how we can rely on just our phones and cloud storage. It is something we are moving forward to but not something that should happen anytime soon.
I love the SD card slot as well as many others. If it really is a problem, Google should start making certified SD specs and placing a seal of approval on them to ease for developers and consumers.
If they need to invent some kind of new type of security or partitioning on these SD cards, then feel free to do so also.
I don't think taking away the SD card is a solution for both parties, it's just a solution for a developer and headache for the consumer. If a tiny bit of research is done, it can be a win win for both parties and Android will have something Apple doesn't.
But what do I know? I'm just a ME, not a CE or CS.
We can complain all we want but external card support is going away. Suggestions as to what Google should do are not the reality of the future. Embracing what will be is a better strategy than wishing it would be different.
Well if they wish them to go then start offering higher storage amounts. Tablets and phones shouldn't even have 16gb as an option. Make it 32 and higher... I wish this tablet had 128gb! At least Apple is offering a solution not just SD cards are bad... And the cloud isn't viable for most.

We as the consumer have the power to push for what we want.
HTC didn't support SD cards, but guess what, the SGS3 and 4 sold well and a lot of people said that the SD card was the selling factor to them, so now both Samsung and HTC both have SD cards.
If Samsung and HTC recognize it as a selling point, they will implement them one way or the other. I don't actually believe the "We can complain all we want but external card support is going away."
I don't really need to move apps to it anyways, I just need to keep my books, documents and music on there. That does not' affect the system.

Not as long as Samsung, the largest purveyor of Android devices, keep including them. HTC caved and added an SD card to the M8 as did LG with their refresh of G Pro. Every Android tablet and the majority of Android phones (by market share) have it. The majority of those that don't are Google influenced (EG: Nexus and Motorola). They'll "go away" when Samsung stops supporting them. And ironically while one faction is trying to kill them another is making them bigger (128GB) and faster.
And it looks like the LG G3 will include an SD option for those outside Korea this time around so the trend continues.

Here's who the death of external storage would benefit:
Developers - their lives become simpler
Wireless carriers - they'll sell more data
Device Manufacturers - they'll sell more $50/100 storage step-ups
NAND Manufacturers (of which Samsung's one) - they'll sell bigger more profitable NAND modules
Google - they'll have more data to monetize as it passes to/from the cloud and can analyze and map what's in a user's Google cloud to do even more profiling to generate even more ad revenue
Here's who loses:
Us
SD Memory Card Manufacturers
If Samsung wanted to sell more memory step-ups they could have followed Google's lead with Nexus/Motorola and joined HTC and others that didn't provide external storage. For whatever reason they chose to stick with the(ir) status quo and more of their competitors seem to be adding external storage support than going the other way. The new Tab4 starts at 8GB of storage to keep the price down. With the OS you could probably store five pictures and a 30 minute TV show before storage was maxed out. Skimpy storage with expansion options actually helps lower the average selling price. So unless Samsung has a change of heart about external storage I don't see anything changing in the near future. Even If all other manufacturers abandoned it with Samsung's market share the majority of devices sold would still include it. So, at least to me, it appears the future of external storage depends more on Samsung than Google or a bunch of lazy developers.
The restrictions on the SD card have been in Android for a while. Samsung had made the one line change to get around the restrictions. However, in KitKat, probably with pressure from Google, they've removed that one line change that permits all apps to read/write to anywhere on the SD card. While 90% of consumers won't notice -- they only use external SD cards for movies and music -- this is a step in the direction of eliminating external SD cards by Samsung. Or, at least limiting them to what 90% of consumers use it for. Eventually, I believe, they'll eliminate them just as most others have.

Nope. It was Google who made the one line change in Android specifically starting with API 19 in 4.4. From Google...
External Storage Technical Information
Android supports devices with external storage, which is defined to be a case-insensitive filesystem with immutable POSIX permission classes and modes. External storage can be provided by physical media (such as an SD card), or by exposing a portion of internal storage through an emulation layer. Devices may contain multiple instances of external storage.
Access to external storage is protected by various Android permissions. Starting in Android 1.0, write access is protected with the WRITE_EXTERNAL_STORAGE permission. Starting in Android 4.1, read access is protected with the READ_EXTERNAL_STORAGE permission.
Starting in Android 4.4, the owner, group and modes of files on external storage devices are now synthesized based on directory structure. This enables apps to manage their package-specific directories on external storage without requiring they hold the broad WRITE_EXTERNAL_STORAGE permission. For example, the app with package name com.example.foo can now freely access Android/data/com.example.foo/ on external storage devices with no permissions. These synthesized permissions are accomplished by wrapping raw storage devices in a FUSE daemon.
Since external storage offers minimal protection for stored data, system code should not store sensitive data on external storage. Specifically, configuration and log files should only be stored on internal storage where they can be effectively protected.
http://source.android.com/devices/tech/storage/index.html​
Here's some other things to ponder...
If external storage was killed tomorrow it'll be years before Android and developers can stop supporting it. What's supposed to happen to existing device owners with low amounts of internal storage and tons stored on their external SD cards? FYI, there were 900M Android devices in service in 2013.
Now that we're all being marketed in to the "must have" status of 4K video, where's it going to be stored? Uploading, downloading, and streaming 1GB+ 4K videos via a cloud will certainly make the wireless companies and DropBox happy.
The bottom line is that no matter where any of us stand if there's a progression away from external storage it will take years.
I'm not sure of the reasoning behind this move to remove external storage - yet I doubt it is security. They are still utilizing EXFat or Fat32 for the file system on these cards it would be simple enough to use ext3, ext4 or a slew of other options.
They really are not considering the user when doing this options. The rural consumers where internet has caps and current cell phone plans where you need to mortgage the house to pay your cell phone bill because you only have one option. It would be nice if there was cable internet access available - would even settle for DSL.
With the use of external storage moving/recovering from a failed device to new device is so much quicker and easier to accomplish. There is no worries if you will hit your caps while trying to recover. Spending more time in locations that do not have service is a bit easier as I can have more movies/music/documents with external storage.
The loss is becoming annoying and will end with the device being rooted to gain back the features that were purchased in the device to begin with.
quite a few of us with windows tablets utilize the option of installing applications on external drives all the time. windows tablets generally come with the same amount of storage as an android tablet and since window full apps are far bigger than mobile apps an external option is almost required. its a pain trying to launch rust from my t100's sdcard, but at least I have the option to do it. and with my 700t I can crack it open a install a larger msata if needed. i think most of the higher end windows tablets have upgradeable drives... at the cost of loosing warranty however.

You are forgetting that the voice of the customer is a powerful business tool. If we avoid the devices that do not have expandable storage (external cards), then the device manufacturers will continue to make devices with expandable storage. I for one will not even consider a device that does not have expandable storage. I will just keep my old devices, and when they die I will be done.
The more people that are not willing to submit, the louder our collective voices. Those telling us to "bend over and enjoy it" are part of the problem.
Here's an idea -- if developers are having such problems supporting external storage with their apps then..uh..don't. Just clearly state that in the description of your app, don't support it, and there isn't a problem. But taking away external storage options from people who want to put large movie files on their devices, or record videos or still pics to an external SD card rather than internal memory is just stupid and going to make a lot of people unhappy. All these new phones are being advertised as camera replacements...how many cameras have you seen that only have internal memory? Oops.
If there's ever a day that all Android phones don't support external storage, then that will be the day that I no longer buy a $400 phone under contract every two years. Instead, I'll be buying the $0.99 special that will do voice/SMS, and then I'll abuse the crap out of the data plan by tethering it to a real device. And if there's ever a day that Android tablets don't have external storage, that will be the day that I go back to a ultrabook or (gasp) a Windows tablet. If the industry wants to shoot themselves in the foot, well, there have been larger companies/industries who have failed because of equally stupid decisions (cough cough...Blackberry...cough...Palm...cough cough).

Samsung Galaxy Tab A SM-T550 and OTG

First of all, I'm from Spain so sorry in advance for my English.
A few weeks ago I received a couple of Samsung Galaxy Tab A SM-T550 brand new from Amazon.es to give them to my sons.
I already have a Galaxy Tab Pro 10.1" and used to watch, while traveling, a collection of MKV files from 1 to 10 gb size stored in a bunch of Samsung Evo's 64 Gb Micro SD's , to do so I have a OTG adapter to read the Micro SD's trough OTG micro USB.
Those cards are formatted in ExFAT due to the limitations of FAT32 for large files.
They work flawlessly in the Tab Pro (Stock 4.4.2) with MXPlayer and the proper codecs (also the AC3-DTS custom codec from XDA).
So I tried to configure my two Tab A to do the same, something that caught my attention was their behavior just out the box, one of them worked as expected with no problem but the other one refuses to read the Micro SD's and tells me to format the device because it's unreadable, I tried to use ES File Explorer Pro and when I try to access the USB it tells me that the program is only compatible with FAT32 and ExFAT, that means that it can see or access the Micro SD formatted in ExFAT.
After resetting to factory defaults a couple of times I keep looking for a reason for the different behavior of both identical tablets, except for the color.
Checked with the internal Micro SD slot and it worked with no problem.
At that time I realize what was the difference between both devices, while unpacking, one of my sons that already has an old tablet, put his Micro SD card with some content inside the tablet so we started doing some tests and realized that if you left the internal bay empty the OTG was used as expected, place the card inside the bay and the problems appear.
One of the S7's was replaced at the shop tree times because, when we show them the problem, the vendor tried to use the aforementioned cards with their showroom test units and, because those units are there to show the device to customers, usually they don't have SD cars in the internal bay, as a result their S7 works fine and mine doesn't so they gave me an other and so... tree times
I tried with a bunch of OTG adapters Micro SD cards and Pen Drives with same result...
We try to reproduce the issue with every Samsung device in the house:
Two S5 (Stock Kit Kat) updated to a Lollipop and then to Android 6.
Two tablets Galaxy Tab A with stock Marshmallow.
One A5 2016 (Stock Lollipop) updated to Android 6.
One Galaxy Tab Pro with stock 4.4.2
Two S7 (SM-G930F) with stock Marshmallow.
One S7 (SM-G935F) with stock Marshmallow.
My conclusion is that every device that came with Android 6 from the factory experienced the same behavior.
I want to show this problem to the community to find if other people can reproduce the same issue.
PS: I also tried to contact Samsung Support Chat, and you can't believe the copy & paste point less answers they post is amazing...
Nobody can reproduce this?

In the thread, you said the Galaxy Tab A's were Marshmallow right?
If you said it was Marshmallow on the two tablets, it's because of Google's new SD Card adoption. One of the two devices has adopted that SD Card as their internal storage probably.
If I helped, hit the Thanks button!

No, just out the box, the only difference was the micro SD in the slot, as I've said, a couple of brand new S7's and one S7 Edge shows exactly the same behavior, moreover, as far as I know, after several errors and testing problems, Samsung have removed the "Google's new SD Card adoption" from their devices (is what I heard), I don't know if may be this situation is related to this policy.

SD card issues

My Yoga Book always says that my SD card is missing and I need to reinstall it. I install it as part of the internal storage, this might be the issue. I have gone through three different brands, Samsung microsd card does not work at all for me. Simply will not read, says it is incompatible. The other two work for about a couple hours but then I will reboot and sudenly it will not read and say it is not inserted, when it is. So frustrating. Also when the microsd card is unreadable, I have the second issue of the Book not coming back on after it sleeps or when the screen times out. To get the screen to come back on I have to take out the microsd card and the screen will come right on, but than says " the is no sd card, please insert." Any one else having this issue? I really want to like this little machine but it seems REALLY underbaked.
I have an idea of what is happening with my cards. I have a very good Samsung microsd but the machine first said "This card is too slow" !!! I set up the microsd card as "internal" storage not media storage. Well, the Book formats the card, uses it but on reboot it looses the card and says the card is either "not in" or, the card is "not compatible". So I try to reformat but the Book will not format it and neither will my PC or any other device. I keep getting that the micro sd card is now "write protected" or "cannot format raw data", so now I have two expensive micro sd cards that are completely useless and I am very very upset. I have one other card I can try to use in the Book and format it as "media" instead of "internal" but Im afraid it might raw format it too and Im stuck. AAARRGGHH. Any ideas on how to re-format these micro sd cards?
Hi! Any update regarding the issue? Would be really glad to know if you have resolved it as I am currently experiencing something similar with my Yoga Book (Windows). I have a 128GB microsd and sometimes it suddenly stops recognising it. I've never had the too slow error though. My card was formatted using NTFS.
Wondering whether the card tray design is bad, and if the card gets displaced when moving around. I'll try another card, and will update this post later.
Android must be formatted to fat32, although the best way is to format it in a Android device like your phone if needed. Not sure about your other issues. Is there an update from Lenovo maybe. My card reader is just fine. #knockonwood

Sadly I ended up buying a new microsd card. My two cards that I started with are still un accessible and useless. I format it to Fat32 and inserted into the YogaBook and designated the card as media. It's been working great ever since. Still annoyed that I am out $100 worth of micro SD cards
Good luck to you. I have the Android version.

Hi! (In my case) I think it was due to the "thickness" or dimensions of the microSD. I had one that was slightly thicker than the original card I was using for the Yoga Book. I swapped them, and haven't had any problem since then. Sorry to hear that you had to shell out another $100. That really sucks. Mine was sheer luck. (Thanks to the added "chunk.")
Hope this bit of info will be useful for other YB owners.
Unfortunately I can confirm that ;/
In my case I observed the same...
I have a model with windows. It's EXTREMELY slow! Generally, no just the SD card. Almost impossible to work on it. Lenovo sucks!
According to the SC slot I've tried many different SD cards and always the same... Time of copying 2GB file, calculated by windows, about 672 hours... Only...
This is my second computer from Lenovo, and the last one.
If you're migrating files, try doing small amounts and copy not cut and paste. Otherwise just take the card out and do it on a more robust pc.

I'm using an SD card and it seems to be running fine. Are you using it for something that needs regular access to your SD card? Like, installing Windows or a program on it? Because that will make transferring to and from the SD card very slow, or at least a lot slower than what it would usually be. The technology in the Yoga Book's SD card slot is old, so it can't handle stressful situations.
Hi, Thanks for your answers,
My main HD has 64GB, its not a lot of, so I thought about changing location of My Documents and all my files on the SD card. But after setting of paths to SD the computer froze due to it couldn't read SD fast enough.
So, I decided to move my personal folders back and tried to move files manually.
But the situation is the same :/
Don't you think that transferring of files on the another computer to SD card has no sens??
It is needed for me to move files from YB to another computer, so while I can't do it than the SD slot and whole Yoga Book is totally useless for me.
Do you think, guys, that it is possible to install Android on it?? There is a possibility to boot from the external USB-CD or just USB, but I couldn't find the Android version for YB.
Maybe with Android it will work??
Did someone of you tried to do it??
Thanks

I did delete Windows 10 and try install Android, however, I was not successful in getting it usable. So right now, Android is a no-go for those who have the Windows 10 version (although, you can install emulators that allow you to run Android apps). I usually try to minimise how many things I have on my Yoga Book - keeping apps to a minimum, and I've got my Downloads and Documents on my SD card and it's fine. Maybe your SD card is an old one?
Believe me, I've tried all possibilities, which came to my head
I bought three different SD cards (actually I have SanDisk Extreme microSDXC UHS-II, 128GB, formated in exFat) and nothing.
I tried also to run linux, and I noticed a small difference in relation to Win10, that in linux the copying process is pending all the time, while Win10 is breaking the process every time and ordering me remove the write protection.
Hi guys,
I found a solution!!!
I don't know why, but I created two 64GB partitions (almost, just 50% and 50%) on the card and formatted as a fat32 and.... Suddenly it works!
Thanks for your attention!
Has anyone tried the 200GB or 265GB micro SD cards yet? google search seems indicate that it might work but not able to get any concrete proof.

Yes, I use a Samsung 256GB micro SD card fine in my YB. Insert it and format it using the YB and it'll format it as FAT32. Only problem with that is I need to convert/compress my larger than 4GB movie files to something smaller.
thanks to PPC_Ed's confirmation, I ordered a 200GB drive and was able to get it working on my Yoga Book Android.
512GB SD card

I bought a cheap 512GB sd card on eBay for less than $12 from China. I have stored tons of stuff on it. Downloaded a 1080p movie onto it using the adapter on my laptop and the lap top wanted to fix issues. It did, and everything still is fine. It actually might not be 512gb, but I have more than 200gb on it and it works fine - no speed issues at all. Android still reports 512gb total capacity (499 gb). I couldn't be happier with the $12 spent.
