My Tab S2 is having problems recognising SD cards. At first it would read folders and files, but not write to them. Now it won't detect any SD card that I insert (I've tried 3 different cards). I've tried rebooting, removing and reinserting the card. Sometimes after a reboot it will detect a card for a couple of minutes, and I can read the folders on it, but then the card will disappear again.
Is this a known issue?
Edit: I just managed to view a file on the SD card, and I noticed a notification saying "still ejecting SD card" , followed by "Sd card unexpectedly removed", and the card was gone again.
???
Using good light and an optical aid examine the card contact of the Tab. Check for damage or contamination.
Clean with anhydrous isopropyl on both Tab contacts and cards using a microfiber cloth or cotton swab.
NEVER touch contact surfaces on cards.
Try again.
If no joy:
Clear Tab system cache.
Reformat card in the Tab before use.
If that doesn't work do a low level format using a 3rd party app then format again in the Tab.
Do not write to the card with other devices as this can cause corruption.

I've tried shining a light into the SD card slot but it's too narrow for me to see anything. The card almost never gets removed so I wouldn't expect much wear and tear.
I have no idea how to clear the system cache - only app caches. Do you mean booting into recovery mode and wiping the system partition (effectively wiping it?)
OK I've now tried the following:
1. Low-level formatted two different SD cards using a utility downloaded from www.sdcard.org
2. Rebooted the Tab into recovery mode and wiped the cache partition
3. Wet a small folded-over piece of paper with isopropyl alcohol and tried to wipe the SD card contacts in the Tab.
I sometimes get a notification saying the SD card has been mounted, but this is followed a few seconds later by another notification saying that it has been unexpectedly removed. This applies to both of the SD cards that I've tried.

You need to be creative. Try sunlight or other single point light source plus magnification.
Clear system cache.

That procedure is exactly the one that I followed to wipe the cache partition.
Using a magnifier plus light source the contacts look pretty clean - see photo below.
Is there any point in trying a factory reset, or does this look like a hardware failure?

I can't make heads or tails of that.
A hardware failure is unlikely.
The problem with a factory reset is you never find the root cause, so it can reoccur.
Resets are best used for rootkits and such, after a major firmware upgrade and to correct damage caused by poorly coded apps.
Do some Google searches and play with it a bit more before you pull the reset trigger. I always track down my gremlins... eventually

Hi, Ive searched all over the internet (and these forums) for an answer. I dont know if anyone has had a similar problem, or even better, a solution.
Ive had this problem since I was on an unmodded G1 using 1.5 Cupcake, then I rooted and have been using cyanogen roms since then, and the problem is still present. I am currently using CyanogenMod v4.1.11.1.
Whenever I recieve a notification as music is playing through headphones using the T-Mobile 3.5mm Adapter, The sound totally mutes, and doesnt come back whenever I get a phone call or a text message or if i continue playing music. (I use the default music player).
The only way to restore the sound is to reboot the phone, but if another notification arrives while headphones are plugged in (even when music isnt playing) the problem strikes again.
Any suggestions on how to solve this? Ive tried using programs like Volume Control and still havent been able to solve it... Any help would be appreciated, Thanks!
either try reflashing your radio, or i remember a long time ago, i think i heard about an app called ongoing music adapter that would help.
Thanks, but the app didnt work.
Im gonna try to flash the latest radio off the HTC website, (unless theres some modified radio someone can recommend?) but idk if thatll solve this problem because its been happening since before I rooted or modded my g1.
I tried reflashing the latest radio and still no help. Ive tried every possible app i could think of. I cant figure out why this is happening and its been driving me crazy! Anyone have anymore suggestions please?
maybe it is a ram issue and the phone.apk is causing it to kill your other apps which possibley are not reloading
i don't really know i am taking a random guess but who knows
well I have plenty of memory free on the internal phone storage: 44.78MB and 798MB free on my second partition on the SD card and 1.08GB on the primary.
Idk if im the only person whose has this issue before, because I cant find this scenario repeated anywhere online. Its been like this for as long as i can remember. Whenever headphones are plugged in and music or video is playing and I get a text, email, or notification of any sort (even in silent mode) all the sound disappears till i reboot the phone...i cant figure out the problem. Ive gone from the official Cupcake to all of CM Roms up to 4.1.11.1. Same issue
I flashed the latest radio today and I tried downloading an app called Loud Volume Hack and that didnt help either...any more suggestions? thanks for trying gridlock! i appreciate it!

your ram has nothing whatsoever to do with your memory card size or how much space you have
set yourself up a linux-swap partition
LOL omg that is hilarious
and @op
just disable sound notifications while listing to music
also, does this only happen with the 3.5mm adaptor or does it happen with the usb headphones as well
lol epic fail on my part. now that my n00bishness is exposed let me ask another n00bish question, is a linux swap different than apps2sd? because cyans roms already has apps2sd built in. My memory card has a FAT32 and ext2 partition but Ive read that swap is a 3rd partition? would i have to format my memory card to do this?
disabling sound notifications doesnt work it still happens regardless
and i never tried using usb headphones, im gonna try that, i only used the adapter.
btw sorry for the late reply, ive been busy and my desktop was messed up for a while.
Hello
i have been having in the last few months many issues with my Galaxy note - which was running the official GB and then official ICS
the phone would freeze for a short while (5 or more seconds )- does not responed when buttons are pressed in this freeze position
would suddendly from that position go into the lock screen and sometimes just restart over and over a good few times
Notification would pop up at random - saying the External SD card is safe to remove
it could last like this for a good long while (upto an hour or more sometimes )- doing it over and over again
Even when i rebooted and pulled the battery - still happens
it would do this randomally - could be couple times a day - or couple times per week -
in the end i had enough and yesterday i rooted my phone with the speedmod kernal
that was ok the root and i did a clean wipe of internal SD and re-intalled everything back onto the phone today
and again now its happening all over again
freezes / hangs / safe to unmount external SD card
RIght now - its stopped for a while - but overall phone seems pretty unstable
When i first got the phone -running official GB it seemed ok
and then more and more apps came along and i think it slowly started to happen
its happened with both GB touchwiz towards the later part before i updated to ICS stock with Apex
my phone is sadly not working as it should
would really appreciate advise

Remove sd card for a day and see if performance improves. If so, stick your sd card into pc and chkdsk it, sounds like it might be failing.

thanks for your reply
as i also wanted to check the external SD card - i did the chkdsk and no problems were found
thinking that it could be the card itself i found the link below and have now re-formatted it
http://www.simonjstuart.com/2012/07/06/format-a-64gb-microsdxc-card-for-android-using-your-pc/
says to make sure its formatted with 32kb clusters -
so i am now putting all the data back on and will see how it goes
if anyone else has any other suggestion please let me know
thanks
i have the same problem you have
i did every thing i could but no use
and iam still looking for an answer
what happend to you did you find any thing ?

so i have tried another external SD card in the note
and pretty similar things happened all over again
which makes me to now believe that its an issue with the note itself
its happened to me using official stock GB and ICS and also rooted version
2 different SD cards tested - 64gb and 32GB
i am now reverting back my devise to stock kernal and reset the binary
then off it goes to the repair :crying:
I had a similar problem, but without the SD card issues. It would freeze/hang for varying amounts of time. Sometime just a few seconds, sometime more. I got a app monitor widget and whenever it would hang up, I tried to check the monitor. Screenshots below...i hope.
AT & T replaced the phone last week, and no similar problems thus far.

initial report back from W-Support in germany is that
- Replacement of defective parts
- Adjustment
- Software update
thats all i have from the online status
i hope to get back my note mid next week and will see how it goes..
The water resistance warning message keep coming up when I turn the phone on, I thought wiping the smart connect cache had solved it as someone said it was related, but its just made it slightly less regular if it did do anything (it will now happen around every other time I turn the phone on ) Is this a known glitch, and how do I solve it? Im using latest stock rom.
I know I could try telling selecting the option to never do it again but I want the warning to stay and I know its possible because I had the same stock rom only a couple of weeks ago and it worked perfectly - I dont understand why its suddenly acting up. Ive reset the phone twice, and repaired the phone 3 times (and deleted the folder with the files in each time to make sure it downloaded a new rom).
There also seems to be some problem with the initial NFC update screen as its taken me several reboots to get rid of that everytime.
Thanks

That's not a GLITCH or BUG. And yes it's smart connect app related

Xperia™ Z (C6602) with Tapatalk.
After a charging throughout a night, I woke up in the morning and checked my phone (Note 8 Android 9 OneUI 1.0 unrooted).
All my apps in the Secure Folder popped up on the main screen in a folder called "Work".
(before the day, I had updated my samsung account email and it also screwed up my phone contacts cloud backup)
The workspace mode was turned on, meanwhile I couldn't get inside the Secure Folder. It showed "couldn't create secure folder".
And there is a new button called "Work Profile" on the notification panel, and I did the most regretful thing I had ever done. I clicked that button. The button went grey, all the secure folder apps went grey, then I long-pressed it and it showed another menu (pic2), I turned the "Work Profile" back on, but it only worked on the dual apps, the Secure folder apps still are grey-colored and cannot be accessed (pic3). If I click the app, it shows the Secure Folder Start menu, but it still ends up with "couldn't create secure folder".

(the Samsung Health is the Secure Folder)
Now the main question is how to turn on the internal WorkSpace, it looks like there are two Workspace, the internal one is bound with secure folder.
but the "Work profile" button on the notification panel (which I clicked) have turned these two Workspace off and I only can turn the external one back on.
(the internal one is grey-colored)
So is there any chance to get my secure folder data back? Can I use another samsung phone with well secure folder function to transfer the data?
If you have a SD card slot use the SD card as a data drive, all critical data and backups go here.
Do not encrypt it! Backup that drive redundantly with at least two hdds that are physically and electronically isolated from each other and the PC.
Try deleting the work profile. Not sure why you did that. I don't use secure folder; you are the most likely one to be locked out.
If worse comes worse factory reset I guess.
The Knox ecosystem is complicated, I avoid it... a steep learning curve; K-I-S-S.

I have already made a backup of the external data to a ssd drive with Samsung Smart Switch app.
but how to backup the secure folder data without getting into it?
and how to delete the work profile? I don't see a option of that.
I still have no idea why all these happened, like I woke up and my phone system suddenly changed.
I suspect the charging temperature was too high and it hurt the motherboard, after that day, when my phone runs lots of apps or some apps crash, it will restart automatically again and again, and the phone temperature rises gradually, I have to cool it down physically like take it in the fridge or put it on the floor where is cold, then the phone would stop restart automatically.
You are right, I will definitely avoid the knox when I get my next Samsung phone.

It's easier to learn the easy way then through the school of hard knocks (knox). Unfortunately this a complicated and complex reality. Hard to imagine what you never knew was possible...
I would use multiple hdds not a single SSD. If the SSD's interface fails you are completely boned; if a hdd's interface fails you can still retrieve the data from the platters. SDD's have inferior data retention. One backup copy is not enough!!!
Do Not rely on SmartSwitch for critical data backup!!! Copy/paste critical data files then verify the transfer is complete and readable!
SmartSwitch will likely restore the settings that caused the issue; don't use it!
Backup the data correctly, then factory reset. Make sure Samsung Cloud backup doesn't reset the work profile. Not sure if it can or can't.
You might want to do some research on the Samsung User's Forum before going further.
As far as the overheating it may be just an app. You may have suffered a firmware corruption or a hardware failure. If the reset doesn't solve the issues it will need to be reflashed to the stock rom. If that doesn't work, it's a mobo failure.
Regardless if it's a firmware or a hardware failure setting up encryption, secure folder, or other access locks makes a firmware/hardware failure more damaging and may even completely lock you out. On the other hand if never locked after the hardware or firmware failure it may have remained unlocked making data recovery doable.
Been there, done that... set a bios password on a laptop, it corrupted itself and lockout. Had I never set it likely would have remained accessible
Physical security is the best security...
Hy guys, i want to ask. But first I want to let you know that this is not my phone, I use this phone only temporarily, but I am here and asking because there is something that makes me (sometimes) feel very very upset and frustrated.
This is my brother's phone, and he also asked me to help him in fixing the problem I was about to ask...
The problem is: Automatic freezes and reboots
That simple isn't it? But the impact is big, during that phase I can only use this phone for only a few minutes because my phone keeps freezes and auto reboots, basically during that phase, I can't do anything, all I can do is wait until it returns to normal or turn off my phone for a few minutes which is obviously quite long, more than 10 minutes going like that (freezes and auto reboots). Version number 52.1.A xxxxx (I forgot, there are clearly 3 numbers at the end), I tried to downgrade to version number 52.1.A.3.92 but it didn't change anything.

oh yeah, the trigger is a change in everything related to connectivity (WiFi, bluetooth, gps, sim card, etc), even when activating auto-rotate. Hard reset, flashing, downgrade, reset connectivity, nothing helps. Can anyone provide a solution? can downgrading the android version or using a custom rom help? is this just a software bug or a hardware problem?
thank you

I'm also having the same problem. Is there any solution?
I have same problem
My xz3 is so01l
I guess ta broken
Who can help fix?
hey i have had this problem for months now. Recently I flashed to a custom version (originally on SOV39) and i rooted my device and the problem still persisted. However, I found a temporary fix without messing with the hardware.
By disabling the sensors and then rebooting. It stopped randomly restarting and I can even use the device with airplane mode turned off while having all the internet functions working.
You can find it on Developer Settings - Quick Settings Developer Tiles - Sensors Off. From there you can just toggle it off on the Quickbar menu and reboot the device. Hopefully it works for you too!
I have same reboot problem, only restarts after a min in normal mode. Works fine in flight and safe mode
I took a notice it can be the cell radio as it is off in plane mode.
I find side sense and one hand mode. Is it the things to turn off? I have the same problem, works fine in flight or safe mode. Some wrote it could be the cell radio.
I have checked for the updated version of Android System Webview as another wrote in another thread it could be that by going to Apps and Storage - Play Store. But it is not on my phone so that can't be the problem for me. I have turned off 2 sensors, side and one hand mode but it restarts after a halv min in normal mode.

I tried the same solution (update system webview) and didn´t work for me, I´m currently performing a software repair to see if it helps, the thing is that my phone doesn´t reboot as often but still it´s upseting me.
I was able to partially solve my problem with my phone, I took out the black antenna frame and very carefully placed transparent scotch tape (because it´s thinner than medical tape) in all the contacts that are marked in red in the atached picture but now I´m thinking that I shouls have placed tape also on the places marked with green.
So what change I experienced on my phone with this method?
well the phone now has Network and wifi signal all the time and very ocassionaly it does lose the network and wifi signal for a second but when this happen the phone does not say that there is no sim card and does not freeze and restart, it just recovers signal by itself and I can continue using the phone.
