Hi All,
I got my Xperia ZL some 3 weeks ago, and since I'm still within my return period, I wanted to see if anyone else is having problems with frequent µSD card disconnects - to get a feeling for whether this is a firmware issue (correctable via upgrade) or I have a dud.
I have been fairly unsuccessful in getting my music synchronized with iTunes on my Mac. Although part of the problem is the horrors of the Sony Media Bridge application, the real issue is that my memory card keeps disconnecting while files are written to it! It reconnects a second later, but then Android keeps "Checking for errors" for some time before it becomes available again. Meanwhile, the synchronization stops.
I've also tried TuneSync from the Android store, with similar results. This application lets you synchronize in two ways: via Wi-Fi or by mounting the memory card to your computer (either using Mass Storage mode on the phone, or by physically removing it and using a memory card reader). WiFi sync always fails for the reason above, as does syncing in Mass Storage mode. If syncing via a memory card reader, the sync completes, but then there are all kinds of issues when reinserting the card into my phone, while TuneSync is processing the wired sync data.
My card is a SANDisk 64GB class 10, but I've also tried a SANDisk 32GB class 6 card with similar results.
Let me know if you have seen anything smilar - and better yet - if you have managed to get around it somehow.
Failing that, I'll probably return this phone in favor of a HTC One... (I prefer the ZL, but not if it's not working!)
Have the same problem. Read somewhere that there are problem with SanDisk ultra cards.

I've used the same card in my Nokia 808 PureView (Symbian) for nearly a year without any such issues... So there is obviously something specific to the Xperia and/or Android that does not jive with these cards.
Also, my other card (the 32GB class 6 one), although SANDisk, is not "SANDisk Ultra".
Good pointer though! I'll try to dig up some cards from other brands to have a go!
Thank you! :good:

This is interesting. I've now seen 2 dead Patriot memory cards in my husband's ZL ... switched to a Kingston card in that phone now & will see if the problem continues. I'm currently using a Samsung 32gb card in my own ZL and haven't had any problems (I've had the phone for a few weeks).
No issues here
I've been using my sandisk 64 gb microSD (Class 10) on my ZL without any issues for over a month. Before, I had used it on my note2 for 5 months with no issues. Its strange many people are having issues with sandisk cards. But, I can tell u that its not an issue specific to Z/ZL, it's rampant across the recent Samsung phones too (note2/GS3)! I guess it must be a bad batch of cards by sandisk or something. Btw, I'm on rooted stock rom with locked BL & only formatted my sdcard once using phone (ZL) before using it. I also have a 32gb sandisk (class10) & 16gb sandisk (class 4) microSD cards working just fine on my other devices.

This is not problem with the phone, The SD card itself have got a problem with major smart phones. better keep your ZL
So as a new android user (switching from apple) i realize how much i've been missing out on the beauty of Android devices. So that being said i am so happy to be here and posting about this new friggin device!
SO heres the problem that i realize: Most micro SD card does not work with this new device!! I've tried installing it in the note 10.1 and realize that in the end it cant read. However, if i put it in my s4, it does read and store data. So i emailed samsung personally and they basically said, "as of right now, there arent any micro sd card that is compatible with the note 10.1 2014. Can anyone confirm this? Has anyone used a micro sd card with their device yet? If so what brand? I have a kingston.
I am using 32gb Kingston with no issues. If it is recognized by your phone, try formatting it inside the phone then put it in the tablet. Most likely the card is not formatted properly.

Yeah it's most likely this.
I'm using a 64GB SanDisk Class 10 card formatted to exfat.
Plenty of help on the web if you are unsure of what your doing.
Good luck!
i tried a brand new PNY 64GB formatted to exFAT. it worked fine until it die- two friggin days!
now i'm using my back up 64GB sandisk. it's working fine so far, exFat too. had one incident that made me think that this may be a dud too, or that the 2014 may be killing my disks. i'll have to keep an eye out.
There are way too many reports of this for there not to be a problem! I myself had a card that worked great in my old Note 10.1 and my cell phone but had to be formatted for the 2014 edition. Why? No reason other than something just ain't right somewhere!

That's what I'm using too, though Kingston makes good memory, and I've had good luck with other companies as well, like Patriot and Trend Micro.

Have not seen way too many reports of this problem with this particular device. The problems lie in the the memory cards not the device. Flash memory is notorious for just flat out dying or not working in certain devices. Sandisk or Samsung are the top choices for broad compatibility, hence the fact that their prices are usually higher. Probably due to more R&D and testing. I just swapped my 64gb Sandisk for the Kingston 32gb with no issues. I had the 64gb in an Acer W3-810 Windows Tablet.

My bad. There is only this thread and another thread on the next page. It is kinda suspicious that my 64GB card as well as others here works fine in my other tablet and phone but just won't work in my new 2014. Call it what you want but to me that's a lack of plug and play!
For everyone without any issues of course we are just making a mountain out of a molehill but for us FEW sitting here with a 64gb micro card that won't work consistently this is a fail!
So yes I surrendered and picked up a 32gb card and it works flawlessly.
i have a 16GB patriot Class 4 that i pulled out of my Nook Color (and formatted on my computer) i have had no issues using this.
one thing i did notice, is that the sd slot in the galaxy note 10.1 is pretty deep, i cant get the card in without assistance, usually from a pen or key that happens to be nearby.

Do not make this in to something personal. Please read what I typed. I was not trying to deny there is a problem but let people know where the problem comes from. One android device works with a card but it will not work with another. It is more than likely the card. You made it sound like it is Samsung's fault. They cannot test every card with every device ever made. People should be asking for help from their card manufacturer. My original 64gb died right out of the box and Sandisk replaced it.
I'm sorry if this came across as personal. I apologize for that. We just disagree and that's fine. You think it is the card even though it works great in 3 other devices, my laptop with the insert, my phone, and my old Note 10.1 and I think it's the 2014 edition because it doesn't work in it. To me if it was the card it would give me some sort of trouble in the other devices.
But to each his/her own.
Maybe its how the card is formatted?

I may be mistaken but I believe I have mentioned that I formatted the card while using the Note 2014. I also formatted it on my PC. It's no biggie anymore since I have a 32 gb installed that works great. I'm just going to wait till another update and try it again. I believe it's going to work at some point.

32gb class 10 Samsung micro sd card works perfectly in my Note 10.1 2014, TAB3 8.0, GS4 & GS3
I'm having intermittent failures with my card also. I took my 32 gb Lexar out of my Transformer Prime and it wasn't recognized by the Note. I formatted it, it was fine for a few days, now it's telling me that the card is blank and/or unreadable. I formatted it again using the SD Formatter. I'm adding music to the card now and I'll be keeping an eye on it. I'll buy a Sandisk if this continues. I'm not at a risk of losing data, so I can experiment a little.
Don't cheap out on crappy low end cards, and you *should be fine. I have a combination of 6 Samsung phones & tablets all using one of the two cards listed below. Have never had a single issue, and a few of the devices have been using the same card for well over a year.
SanDisk SDSDQUA-064G-U46A Ultra 64 GB microSDXC (UHS-1) Class 10
Samsung Electronics 32GB microSDHC Extreme Speed (UHS-1) Class 10
The 64GB Sandisk Ultra is currently formatted ExFAT, and has been working just fine for almost 2 weeks now in my Note 10.1 (2014 ed).
* There is always a chance with failure, as with any electronic component, but good storage cards are worth their price.

Kingston, Transcend, Lexar, AData, G.Skill and Patriot are all good brands as well.
Same issue as above posters, I have a SanDisk ultra 64gb. After mucking around trying to get the same card that worked perfectly in my original. 10.1.
Solution : I backed the card contents up on my pc and then formatted the card in the original 10.1 before checking that I could write a new directory on the card using the 2014 edition.
Seems to work so far, hope this helps you guys (who still have the original 10.1 as well).
I have a 64GB Patriot class 10, No issues. Thought I would chime in.

Anyone try the Samsung 64GB micro SDXC? I can only guess all Samsung Micro SD's will work fine.
I thought I would start a thread on which Micro SD cards were recommended vs. those that fail early or are simply not compatible. I saw a thread earlier that appeared to show that some cards (and sizes) were better than others.
I can report that the Samsung 64GB card (says Class 10, HC, 24MB Read, 7MB Write) does NOT work in this tablet. I was able to use it just fine in my Note 2, and a laptop. However, the card doesn't work properly in my 2014 Note 10.1. An older Pansonic 16GB MicroSD card worked just fine however. I've tried formatting it in other machines, and it's still a bust. Currently, these cards are selling like wildfire on Ebay for $30.
So, what DOES work for a 64GB card? Any help is appreciated by myself and I'm sure a lot of others reading this forum.
Thanks in advance.
I have got a SanDisk 64GB card in mine. Also got the same type in My Note 3.
The SD card issue seems a bit odd, both of my cards were also fine in my older Note 10.1 and the Note 2. I've never had a problem with either of them
Samsung 64GB works just fine.
I have a 64GB Samsung MicroSD and it works just fine, haven't had to do anything to it, worked right out of the box.
Its a Samsung 64GB Class 10, UHS-1, Grade 1, 70MB/s MicroSDXC Pro Memory Card
I always buy memory cards directly from Amazon because there are a lot of fakes out there, so I know for sure this is a genuine product.
This is the exact one I purchased
http://www.amazon.co.uk/Samsung-Mic...5658961&sr=8-1&keywords=64gb+samsung+micro+sd
i've tested my 64GB sandisk on my gn8 for a week now with no issues at all. one day after being put back in the gn10.1 2014 and it's acting up again. files, fail to delete, wrong size reported, inaccessable, etc. the 32GB sandisk works fine. both are uhs-1 formated exfat. take it out without reformatting and it works fine on my gn8 and pc. put it back on the gn10.1 and it won't mount without a reboot.

Hey guys, thanks for the info. After some research I discovered that this was indeed a fake card I ordered from Ebay. Looks like this is a common problem as the packaging is *almost* perfect and you really can't tell the difference without some serious research. Luckily, the seller refunded the full amount back to me. Based on your feedback here I've ordered a SanDisk Ultra from Amazon.
Thanks for the help and & Happy Thanksgiving!

A really good way to check them is to simply try to fill it up. Only 4G of data will be saved and readable, whereas the other 60GB is corrupt.

It's sad that a lot of people get duped into buying fakes. But sites like ebay don't/can't do anything about it.
Memory cards/Usbs should only be bought from reputable sellers only (Amazon, Currys, Play.com etc) as there are wayyyy too many fakes out there.
I'm currently using a Transcend 64GB SDXC UH-1 Class 10 card which was formatted using the tablet.
It works fine except for one annoying problem. When transferring large, singe or multiple files, say 1.5GB+ HD movie or a huge amount of photos, from internal to external storage, the device would freeze. After it starts up again i notice that i can no longer access my SD card even though the device says it's still mounted. The only way i can fix this is by removing and reinserting the card or rebooting the device. Although there's no problem transferring files from a computer straight to the SD card.
Anybody encountered a problem like this? Is there anyway to fix it?

Yes, I'm having the same issue. Except the SD card will randomly lose the files even though it still shows the card is still mounted. Just recently I was watching a movie from the sd card and this happened.
I am using a SanDisk that was being used in my note 2 for the past year (never had problems with it before).
This is especially frustrating when trying to sync files with Plex.

I know I'll sound like a noob, but my 32gb Samsung micro sd card just doesn't seem to work on galaxy note 10.1 2014, yet it worked perfectly fine on my previous note. Would i have to format the card on my computer? A little bit annoying since I don't have a reader for it.
My Sandisk does not work
I have a SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s SDSDQUA-064G-U46A that has a lot of problems working in my GN 10.1-14. It has worked fine for a year in the old Note 10.1. The New Note would not even format it. Formatted it in my Galaxy S4, and it kind of works. Often it simply reports no files, although it will report in Settings the correct size and space available. Sometimes I have to reboot several times for the card to work. then sometimes I will try to open a file and get an I/O error. Then sometimes random reboots, especially if I try to unmount it.
I use a Samsung Pro 64GB microSDXC (UHS-1) Class 10 card (MB-MGCGB/AM) reformatted to FAT32. Works great. I've been using the same type card on my LG Optimus G for almost 8 months 100% problem free (also formatted to FAT32). I did have issues with a SanDisk Ultra 32GB in that same phone that used to dismount itself all the time and I know others that have had issues with SanDisk cards in GoPros as well.
ok, so which one of these sandisk ultra microsd cards will work in the 10.1 2014 edition, and what is the difference between them?

Anyone else getting this error? I have a 64M SanDisk that was working just fine in my note 2. I put it in my notes and I continually get this error. I unmounted, removed and power cycled my phone but it comes back any time I try to access the card. Any ideas?
I would backup the contents of it onto your computer and reformat the card. Then try it.
I've been getting this error when my phone wakes after being idle for a long time. I've tried reformatting the card but I'm skeptical that will fix the problem. According to many online threads, this issue has been widespread across a number of devices, and my card (Sandisk 64GB Ultra CL10) works fine in other devices. Will report back.
This is a common problem with the Samsungs...There is a proper process, as follows.
First, go ahead and do a fresh format of the card and get the contents onto the card.
Second, turn the phone completely off AND REMOVE THE BATTERY.
Put the card into the card slot, replace the battery and power the phone back on.
This has been my process since the sII, and haven't had any issues, save a few completely corrupted cards which were unsalvageable. There is an issue where the card receives current from the battery, and in some cases can corrupt the card and in even fewer (but still entirely plausible cases) completely fry the SD.
I'm not sure why Samsung hasn't caught the issue, or even acknowledged it, but this process avoids it entirely.
Hope this helps
Thanks, I tried that but it made no difference.
The uSD card continues to work fine in my other devices, and diagnostic tests reveal no problems with it, so I'm confident the card itself is ok.
I'm trying another card now (this one 32GB), but I'm guessing the problem will occur with that one too.

Sounds a lot like what happened to my last card in my Note 2. I was able to get a replacement under warranty and haven't had a problem with it happening since.
Well, my guess was wrong. The 32GB card I switched to is actually working fine--no recurrences of the unexpected-removal error.
So I guess there's a problem with the 64GB card, even though it was fine until I switched it from the Note 3 to the Note 4 (and I handled the card carefully).
Good thing, though. It's easier to RMA the uSD card than to exchange the Note 4.

Yup, SanDisk Ultra 64GB. I had no problems with it in my Note 3, though.
I have a scan disk 64GB card that I took out of my Note 2 (rooted) and put in my Note 4. I started getting random unmounted errors.
Finally last night I pulled out the SD card and threw it in my computer. Sure enough it came up and said I had some corrupted files. I fixed the files. Dumped the SD card to my HD and then formatted the card in my phone. Then I put my music, pics, videos, and a couple of files for apps aback on the disk. So far no more SD card issues.

Flickr gives you a free terabyte of storage that you can auto-sync your phone's photos to. That way you don't have to buy a large SD card, and you don't have to worry as much about losing photos due to disk corruption.
Yeah, I tried formatting my SanDisk several times and kept getting the same issue any time the phone tried to access data or write to it. I put in an old 32M cheapo brand and have had no issue at all
3 days and no errors. Maybe the Note 4 doesn't like SanDisk brand SD cards?

I'm happy to report that the RMA replacement for my Sandisk Ultra 64GB uSD card arrived today (the replacement is a Pixtor rather than an Ultra), and so far it's working flawlessly.
I have been dealing with this error with my Sandisk 64gig also. Didn't have a problem with it on my Note3. I have reformatted to numerous formats. Anyone know of a specific one that works. Always have had trouble out of Sandisks on Samsung galaxy products. Some I don't , but I have had this problem on at least 5 different devices. I have always read that the thing to do is go with Samsung brand SDs. The new 64gig Samsung is apparently faster than any other micro SD. However, since I have paid for this one, I'd like to use it.
I just installed a new 128gb microsd (sandisk ultra), and for some reason it keeps unmounting then remounting a few seconds later. I tried formatting it but theres no option in the settings. Is there any way to fix this? Is it only an issue with cards > 64 gb?
I face the same problem with 64gb SDxc sundisk card!!!!!
Any help....... please
I had 64gb microsd fitted last few months, a Sandisk card. No problems at all. Recently fitted a Sandisk 128gb card from Amazon.
Had constant unmounting problem, reformatted to fat32, and still unmounting virtually every hour. Draining battery fast as well.
So, fitted 64gb Sandisk again, problem solved, it doesnt like 128gb card. 128card now in a Win10 tablet and working fine !
Although ASUS only qualifies 64GB MicroSD as max, you should be able to use up to 128GB as long as it is formatted as FAT32. Some users had their's work fine with this size.
Zenfone 2 supports microSD, microSDHC, and microSDXC, with speed class up to Class 10

Thanks for reply Asus_USA. It could be a compatibility issue, the card I tried was a Sandisk Ultra SDXC class10 (newest version) supplied by Amazon.
Has anyone else had any success with this microsd in the Zenfone 2, I have the 32gb, 4gb ram version.
I have a similar issue. Read the forums and it is obvious many asus ZenFone owners are experiencing this problem. Can't asus just admit the problem and fix it and announce the fix? Or is it a bigger issue that asus will not publicly admit to?
I thought I would chime in as I too am having the same issue with my phone. I put an sandisk 128gb sdxc card in my phone when I purchased the phone it worked fine until New Years Day when I got an OTA. Since that OTA, the 128gb card will keep mounting and un mounting itself. I put an 64gb card in and for a whole day, did not unmount once. Called amazon to replace the card thinking it was the card, amazon gladly replaced the card, inserted the card and it is still unmounting-remounting. Like I said before it worked for 1 month straight with no issues in Dec. before the OTA, but after the OTA, its intermittently unmounting-mounting. Thought Id chime in since ASUS was responding and noticing others having the same issue. Obviously its a software issue with ASUS.
There are already so many issues regarding to sandisk sd card on Zenfone, I used to have the same problem, then I replaced my sandisk with samsung, problem solved.

Thanks for your help! I kind of figured it was the sandisk card because I put a little 64GB sandisk card in and the phone wont even recognize that card at all. I put a sony 64GB in and it held perfectly for 1 day, no unmounts. Off to Amazon to purchase a Sony 128GB!
After updating the latest version 2.20.40.160, my micro SD Card Adata 64G is assembling and disassembling every hour.
In previous firmware version that did not happen.
Something bad that ulima update.
My Adata 64gb card did that on the previous update, and more often at times. With the latest, the problem ceased.

i have 16 gb and facing the same problem. Maybe the cause of this problem is the firmware it self. try to update to the latest firmware
Have you tried formatting it to fat32 and remounting it?
From what I've tested, exfat has given me issues. But I'm on a custom ROM (CM 12.1 based), so YMMV.
If you're rooted you can try Aparted on the Play Store and not bother with the PC route. Just make sure you know what you're doing!

That latest update definetly caused issues with SD cards not over 64Gb but with specific manufacturers. Of course ASUS will not assist in this nor claim responsibility as this was in improvement update. Even though it was quite large for improvements. I would like to see what they say as even some 64GBs cards are not working either and they approve all cards upto 64GBs. Unfortunatley, your going to have to switch card manufacturers to get your card to work. I put a Sony card in and it works fine now. I could'nt get a 64GB sandisk to even recognize let alone the 128GB mounting/unmounting. Good Luck!
Having the same problem with 128 SanDisk (also class 10).
Looks like I'll have to buy a new card - am I better off with 64 GB or changing companies?
Yes.. it's a know problem, without a concrete solution... also me I purchased first.. read after... so I sold and I bought a kingston 128gb and since then, it works flawlessly (except it's 3gb less, but I seriously actually don't mind )

Luckily I had a 64GB and a 128GB card and they both had issues. So I just left sandisk all together and went Sony 128GB and it works flawlessly. It just seems like sandisk and this phone does not get along.
Both of you that have 128 GB but other companies, no issues experienced at all? Are you also on the 32 GB version and which firmware?

I have all sizes of sd card , 16,32,64,128 and 200gb...
I have both the 32gb phone and the 64gb phone. I have used exfat formatted sd cards, both 64 and 128gb, in both with no problems. I haven't tried the 200gb as I use that in my tablet but it is the ONLY Sandisk I have... All other cards are Samsung or the 128gb Lexmark. I have these as Sandisk had problems in other phones too... Never had a problem, ever, after changing away from Sandisk...
Sorry, should've added I'm on 178 firmware - the latest...
