I am having the same problem. I have tried every potential "fix" for it. It seems that some devices have this issue. You will need to replace the device. Its a hardware issue. The SD gets disconnected for a few seconds and all the content freeze the phone. Its a bad connector inside the tray. Get a new one.

---------- Post added at 01:57 PM ---------- Previous post was at 01:52 PM ----------

Please also note that many people got 3 replacement before having the right device. Which makes be believes that even the "good" phone will eventually have it (eat, cold, sun, etc.). This is only my 2 cents. Samsung is aware of the issue but will not acknowledge it (for sure). I could imagine that they are working on a permanent fix in their chain of productions for the new shipments to arrive. I am sure they do. So for us, we had the "test" device lol. Same thing when you buy a car with a totally new model. Lots of recalls.

Good Lock from Galaxy App store has resolved my SD card notification issues. SD Card Monitor app confirms this.
[Samsung Galaxy S7 Questions and Answers] Christian99:
What is the name of the app.? And what do you mean by galaxy store?
[Samsung Galaxy S7 Questions and Answers] pkaczor:
The name of the app is "Good Lock" and is available via Samsung's app store. On my phone, it is "Galaxy Apps" in the drawer. Notably, in the "What's new" for version 24.0.6 it states "Fixed issue that SD card is not working."

I am running it since last night. The notifications have miraculously stopped!

When I search in the Samsung app store for "good lock", it gives me only good lock cm themes.
[Samsung Galaxy S7 Questions and Answers] pkaczor:
Perhaps this is a consequence of you being in Canada? I'm in the US. If you search for "Good Lock," much has been written recently in the Android press (just not as a resolution to the SD issue). See youtube as well. Good luck.

Indeed it says not available in my country even with a vpn from USA ON

---------- Post added at 04:04 PM ---------- Previous post was at 03:56 PM ----------

I doubt this will make any difference. I can have no notifications for 2-3 days and they will be back. I was able to get the apk here http://www.sammobile.com/2016/03/29...screen-for-your-galaxy-s7-and-galaxy-s7-edge/ Its available for everybody. Only the US gets it in the Sam app store. But you can get it from that link at the end.

Good LUCK !!! I will report back.

For those who don't live in the US and wants to try the app, you will need to enable "unknown sources" . Once the apk is downloaded, it will tell you if you want to do so. Just say yes and then enable "unknown sourccss

I can now confirm: This app has noting to do with the issue. It even reset my lock screen settings, my background, etc. I have uninstall it. Not even worth (for me). Does not resolve the SD issue and really has noting to do with it. Thanks for trying :)
[Samsung Galaxy S7 Questions and Answers] pkaczor:
I think you're jumping the gun a bit. Again, I have this installed since last night and my persistent SD card notification have completely stopped (as verified by the SD Card Monitor app). Notably, the release notes for the current version of Good Lock (which you can't see since you are sideloading) reference an SD card fix. The merits of the app are debatable, but at least for me, it has fixed the SD card notification issue.

This solution was not my finding, but something I found in the link I provided earlier.

Just so I'm clear- are you saying that you received an SD card notification while Good Lock was installed on your device (other than at startup)?
[Samsung Galaxy S7 Questions and Answers] konoplya:
some good info, thanks guys. I'll look into the good lock app. is it like a launcher app or what?
[Samsung Galaxy S7 Questions and Answers] pkaczor:
Something like that- a replacement UI, which makes me believe that this was a software issue all along.

NOTE that it looks rather "rainbow brite" with the default settings. You can tame this by opening the app --> routines --> default and then choose a more muted color scheme. There is also a good bit of text in the tutorial items that was obviously Google translated from Korean.

Either way, these are minor quibbles given the SD card correction side effect. I remain perfect since installing it- zeroes across the board for SD card mounted/ unmounted/bad removal/removed/ejected in the SD Card Monitor app. Before installing Good Lock, it was notifications galore.

Good luck/lock!

I don't want to replace my ui though..

It's a motherboard issue

I had the same problem. Had to send it to a Samsung service repair. They changed the motherboard officially. It did happen to quite a few devices. Although not a lot if you compare it to the millions sold... But yes it's a known issue by Samsung. Those who don't have the issue will never have it. It's just normal that a few thousands devices out of millions have some defects.
[Samsung Galaxy S7 Questions and Answers] GaMeFaNaTi3:
I don't know if this is the same issue but sometimes when I restart my phone the sd card can't be read properly. If I try to unmount and then mount in setting it will complain that it is corrupt.

To fix it I have to open my sim tray and close it then the sd card will be fine again.

Anyone have issues like this? Hope it's not a hardware defect if it happens only when I reboot the phone.
[Samsung Galaxy S7 Questions and Answers] Christian99:
I would remove the SD. Copy all your file to pc, asides from "android and LOST. Dir), reformat the SD from pc, re-insert SLOWLY AND CAREFULLY the SD in the phone, reformate the SD within the phone option, copy /past the content in the SD using cable to pc. If all this, if the problem persist, it IS a faulty motherboard. No matter what people say on here. So replace phone.
[Samsung Galaxy S7 Questions and Answers] Christian99:
Its a major issue

I got my new S7. I have no more SD card notifications at all. Not even when I reboot the phone. Yesterday (again) I was listening to music (a set of 2 hours long) from my SD card. I started to look at pictures (again) at the same time. After 40 mins or so, my phone stopped the music and stopped being able to read my SD. Everything froze and I had to reboot. Then, again, a few mins later (listening to music and looking at pictures), it did it again. On the second time, I was not able to reboot the phone using the power button (keeping pressure for 10 seconds). I had to do it using the volume down/home/power. The phone screen was totally black and there was no way to unfreeze it. My notification light was flashing blue (as I had new emails and text), but the phone was not responsive at all.

It seems like Samsung just removed the SD notification as a whole in the new phone but did not fix the issue.

For those who don't have the issue, before commenting, I would appreciate if you could listen to music and look at your pictures at the same time (all from the micro SD card) for at least 30-40 minutes.

I strongly believe that ALL phones have this issue, but that those who don't just have not access pictures while listening to music (demanding on the SD card reading). Do it if you can... and see if it creates problems. And let me know once you did the above. Thanks.

After every restart (or after exiting ultra power saving mode) I get a notification about the SD card, with Explore and Eject as options. Once I clear it, it's gone until the next reboot. Is this normal or not? I'm confused.
[Samsung Galaxy S7 Questions and Answers] konoplya:
the issue i have with mine is usually when i'm taking pictures and have it set to write to the SD card. then all of a sudden it will tell me that its "unable to save to SD card" and that its defaulting to device instead. then, when i go to gallery or another app that i use to browse pics, the SD card is not visible at all. if i use a file explorer app for example, the SD card will be visible with the files, but you can't open the files (as if they're not there). sometimes restarting the phone won't work either, i have to literally remove the SD card and put it back in.

i believe that's normal. i have the same thing happen every time i reboot.
[Samsung Galaxy S7 Questions and Answers] Christian99:
I had this on reboot with my first phone (+ randomly coming back when using it). With this one, no notification at all = samsung did got it off totally so users will not notice when it gets ejected. It is supposed and fully normal to get this notification on reboot as the SD card gets disconnected and reconnect with a reboot, same with the sim. Same thing if you remove the tray and re insert it. I don't get them in any events anymore (which is totally not normal).

wow dude thats really shady. i'd call them up and go off on them. its unacceptable.

to update you guys, I changed out my sd card from crappy Kingston to a Sony one and it's been over a week and haven't had any issues. hoping it was the card and not the hardware. will update later if anything changes.
[Samsung Galaxy S7 Questions and Answers] daffie:
I'm having an issue where sd card is not recognized any longer *only* after using a 3rd party File explorer (Solid, ES). Somehow the ID of the sd card has changed and for example Tidal music (offline storage on sd card) can not be found any longer. Very frustrating and weird behaviour.

The only solution is to re-format sd card and restore all offline music.

I'm using a Lexar 1000x 128gb card, similar issues I've been dealing with after the May 2016 update. The Card doesn't say its not recognized, it just randomly drops photos from the gallery and after 30-40min of music playing over Bluetooth the songs start randomly skipping etc. I'm over Samsung. this **** is killing their name, and I'm getting out!

[MENTION=3057673]konoplya[/MENTION], it has been 5 months since your post, I was wondering if by now you can assess that changing the SD card indeed resolved the matter for you?
[Samsung Galaxy S7 Questions and Answers] RiTCHiE007:
yes i had lots of problems with the phone and its sd card reader i think. Like when i charge my phone the whole sd card is gone and after a reboot it comes back in most cases. I also did own a kingston card and it would make my phone freeze a couple times a day it seems and now that i have this samsung evo card it seems good but not perfect.
[Samsung Galaxy S7 Questions and Answers] konoplya:
yes, absolutely. never had a problem since then. i would get a nice higher end card. like sandisk extreme or similar. its worth it.
[Samsung Galaxy S7 Questions and Answers] David Baxter:
Yes I'm also experience these issues. Tried 4 different SD cards. Video especially, to many weird issues. I do not even trust it to properly hold any files for me even to transfer the data stored on them to another device!

This renders the SD card slot useless. I have 7 different android phones and tablets, this is only happening on the S7 Edge that I.m currently using as my primary device!

My S7 930F just ate my Samsung 128 microsd... Something crazy happened preventing the card from formating or event changing the partition table.
[Samsung Galaxy S7 Questions and Answers] JMD04TSX:
I have just had my S7 eat my third SD card and I'm not happy...... I've been in the IT service industry for 20 years so I do extensive troubleshooting before conclusion. I got my phone in the beginning of April and I started with a 32G Patriot card that I had been using in my previous phone (Blackberry). When space on the 32Gb started to become an issue I upgraded to a 128Gb Lexar 633x. That card stopped working within 30 days of use - Phone nor windows PC would recognize the card.. Thinking it was a faulty , cheap, low reliability card, I returned it to amazon and read reviews on many other 128GB cards. I settled on the Patriot Memory 128GB LX series card. That card worked for about 45 days before it stopped being recognized by the phone and having read errors in a PC. I contacted Patriot, asked for an RMA and returned the card. (That was last week). I returned to using the original 32GB card, and that completely died on me sometime over the last 2 days.

I have dropped my phone on occasion, but i have a Gear4 case on it, the phone is still perfect but maybe somehow it's ruining the SD?
[Samsung Galaxy S7 Questions and Answers] Doelpher:
I just got back from vacation and prior to the vacation i upgraded my SD card from Sandisk Extreme 64 GB to Samsung Pro+ 128 GB. On the vacation i have experienced many problems with the Samsung card. The problems doesn't start right after I insert the card, but shows up after a while (hours/days). Pictures/video suddenly disappearing, gallery app force closing and SD card reporting as corrupt. If I insert the same card in my PC i can not see the files taken while there was a problem, but i can see older files. When i insert the card in the phone again the problem comes back again after a while.

Same thing happens after i format the card.

I have no problem with the my old Sandisk Extreme 64GB card (besides the size of storage), which is now back in the phone.

Until i saw this post i thought the problem was the Samsung SD card.

Kind regards

Hi,

Just to let you know that I had an issue with 2 cards :

- Transcend 32GB Class 10 : format > corrupted some hours later, every time.

- Sandisk Ultra 64GB UHS-1 : format > randomly unmounted every 2 days or so, then corrupted. Reboot fixed it for 2 days and it went all over again.

- I tried the tape fix, the slow insert fix, the firmware change (official) but no luck.

I had a 2GB Integral card and a Sandisk Ultra 16GB that worked flawlessly for more than 2 days.

So, an option was sending the S7 to SAMSUNG, which means no phone for weeks and the risk of water resistance loose etc. I didn't feel confident.

I bought a Sony SDXC 64GB last weekend and it's still sitting in my phone without a single glitch. No random unmount, no corruption for now 7 days. I sincirely hope it will last that way...

So maybe the issue was with my Micro SD cards.

I'll keep you informed...

Still no issue as of now.
[Samsung Galaxy S7 Questions and Answers] sagie:
Much like the previous poster, I also had random unmounting of the memory card on a Galaxy S7 loaded with a Sandisk Ultra 64GB UHS-1.

These problems were gone (for several months now) after I replaced the card with a Samsung 128GB EVO+ UHS-I .

[Asus Transformer TF700] kenhanley:
Some time ago I successfully unlocked my TF700 and installed one of the Cromi-X roms. The machine wasn't improved that much and was still very slow with frequent messages asking if I wanted to wait for apps to respond or to close the app. I thought I would try the "Revisited CROMi-X-ET_v3.0-RC2" rom as that allowed the f2fs file system and I wondered if that would be faster. I installed TWRP version twrp-3.0.0-0-tf700t and did the install of the above rom using TWRP and choosing all the default options which reformatted some of the partitions to f2fs.

On reboot I got the start screen and then after a while a reboot again repeatedly. I tried booting to recovery and just got the Teamwin screen.

I then reinstalled TWRP using fastboot and a USB connection. I have tried twrp-2.8.7.0-tf700t, twrp_tf700t_kang_2.8.7.4, and twrp-3.0.0-0-tf700t and all give error messages when I do a wipe, try to restore a previous backup or try to install a new ROM.

On 2.8.7.0 the log I get from a wipe is:-

E:Unable to find partition size for '/misc'

E:Unable to find partition size for '/staging'

E:Primary block device '/dev/block/mmcbblk0p8' for mount point '/data' is not present!

E:Unable to mount '/data'

Updating partition details...

E:Unable to mount '/system'

E:Unable to mount '/cache'

E:Unable to mount '/data'

E:Unable to mount storage.

The twrp_tf700t_kang_2.8.7.4 version gives similar messages except it says failed to unmount system cache and data. The log from twrp-3.0.0-0-tf700t is the same as the kang version except this one says failed to mount the three partitions.

After reading another thread with similar symptom, I tried to format a partition using adb with the shell command:

make_ext4fs /dev/block/mmcblk0p8

this returns Need size of filesystem.

I would be grateful if anyone could help (or is my tablet irretrevably bricked).

What's the version of your bootloader?

Boot to TWRP and run "adb shell dmesg > dmesg.txt" and post the resulting file.
[Asus Transformer TF700] kenhanley:
I did this some time last week but got no text file for some reason. Repeated it without the redirect to file and copied from the cmd window. It's a very long file however. Do I paste it in here or is there some way of attaching it so you can see it (I'm new to posting in forums)

How do I get the boot loader version?

Thanks for trying to help.
[Asus Transformer TF700] _that:
This forum has a feature to attach files (use the paper clip icon). I'm not sure if new users are allowed to attach files - if not, put your log on pastebin and add the relevant part of the URL to your answer.

Boot to the bootloader (Power+Volume down), read the small text in the upper left corner.
[Asus Transformer TF700] kenhanley:
As far as I can tell with two pairs of reading glasses on (its an age thing), the second line reads

Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14.10-20130801" R03

Insidentally I just descovered that TWRP only runs once after installing with fastboot. If I power down I have to use fastboot again each time and re-install twrp.

I don't see the paperclip and - sorry to be so ignorant but - how do I logon to pastebin

Regards

Ken
[Asus Transformer TF700] _that:
OK, that's the correct version.

You need to fully reboot after installing TWRP via fastboot (however you can go directly to the bootloader menu and select RCK, no need to start Android), otherwise it can't access your partitions.
[Asus Transformer TF700] kenhanley:
I think I manage to paste into pastebin under title KenHanley demsg. Not sure how you get to see it.

[Asus Transformer TF700] kenhanley:
Not sure I understand about the reboot after TWRP install. When I install TWR the tablet is sitting with the three icons RCK Android and Wipe Data. After install completes if I press Vol up with the RCK flashing TWRP works. If I reboot straight away TWRP hangs on the start screen or tries to reboot after a time depending on which version I installed. Same thing happens after powering down from running TWRP without the reboot.

Ken
[Asus Transformer TF700] berndblb:
There's your problem, as _that said: You need to reboot after flashing TWRP before you can use it:

Flash TWRP

Reboot into bootloader

Enter TWRP by selecting the RCK icon.

I know you said TWRP hung if you reboot straight away, but that is strange. Describe step by step how you flash TWRP.
[Asus Transformer TF700] kenhanley:
OK.

I boot TF700 with vol down pressed. Connect USB to computer running windows 10. Open cmd window. (copy from cmd window below):

C:\adb>fastboot flash recovery twrp-2.8.7.0-tf700t.img

sending 'recovery' (7372 KB)...

OKAY [ 3.418s]

writing 'recovery'...

OKAY [ 6.528s]

finished. total time: 9.951s

C:\adb>fastboot reboot

rebooting...

finished. total time: 0.020s

C:\adb>

Holding vol down when typing fastboot reboot. Press Vol up when RCK is flashing. Teamwin screen comes on then briefly flashes off and comes on again and that is as far as it gets.

Same thing happens if instead of typing fastboot reboot I press and hold the TF700 power button to reboot.

If I skip the reboot and press Vol up after the flash has finished TWRP starts up and after a delay I get all the various buttons to Install, Backup, Restore etc.. Then I get the storage not mounted problems
[Asus Transformer TF700] berndblb:
Do not touch any button on the tablet after the recovery flash. Just type fastboot reboot, then hit enter.

After you've seen the Asus logo with a blue bar underneath filling up you can reboot into the bootloader and enter recovery.
[Asus Transformer TF700] kenhanley:
Just done that. I get a blue bar when I flash.

After fastboot reboot the screen blanks then the Asus Logo comes up but no bluebar. Eventually after displaying the Asus screen for about 35 seconds the tablet reboots itself in the bootloop I originally mentioned. Booting to recovery gives me the teamwin screen hangup I described above.

I repeated and this time instead of waiting on the Asus screen I rebooted from the Asus screen by pressing and holding power and vol down. Same happens TWRP hangs on Teamwin screen

Sorry I'm causing all this trouble.

[Asus Transformer TF700] berndblb:
Never seen that before and I don't have an explanation for it either....

What kind of wipes did you do before flashing the new rom?

Don't know.. maybe [MENTION=4878287]_that[/MENTION] has a better idea, but at this point I would flash the Asus firmware in fastboot and start from scratch.....

Hang in there for word from [MENTION=4878287]_that[/MENTION], otherwise I can hook you up with instructions for the fastboot firmware flash
[Asus Transformer TF700] _that:
I think it's crashing due to a corrupted filesystem. Reboot to TWRP, and with the splash screen flashing, run this:

adb pull /tmp/recovery.log

Post the resulting file.

To reformat /data as f2fs (be careful with this command and press Enter only after double-checking that you got the "p8" right):

adb shell mkfs.f2fs /dev/block/mmcblk0p8
