SD Card Randomly Appears Empty

Hey, I've had my Evo for a couple weeks now, and have recently started experiencing an issue that has been since happened quite frequently - the SD card will randomly appear empty, and I won't be able to add files to it. The only way to get around this, it seems, is to reboot the phone.
At first I thought my MicroSD card that came with the phone was defective, so I got Best Buy to exchange it today, but it just started happening again! My phone is rooted and running the latest RvU ROM, if that could have anything to do with it. Does anyone have any help, or is this just a hardware problem? (If it is, I'll just exchanged the phone at Best Buy, since I'm within my 30 days.)
Thanks!

Same thing for me. I tried Baked Snack and now Fresh 0.5.3, both have the same issue. Rebooting seems to work for a short time, but it always fails when I'm using programs that access the SD a lot such as the Gallery app or the Camera. As long as I stay clear of those it seems to hold up a bit longer, but I've had it fail while using Astro File Manager too.
When I was running The latest stock OTA I had no issues. I posted a similar question in the threads for both ROM's with no response yet. Because of that, I was beginning to think I had a bad card too.
I don't want to go back to stock. I just can't understand why this keeps happening.

Glad to know I'm not the only one.. I just wish there was some resolution to this.
I contacted HTC and they said it wasn't a known issue with the phone, so they said I should go to Best Buy and exchange it. So maybe our SD slots are just defective?

I have this problem too. It empties every day it seems and I need to reformat the SD card just to get it working again. It erases all my pictures and video and is very frustrating.
It seems to happen most often when I am taking a picture or going into Gallery, but has happened in other instances as well.
I hope HTC releases a solution that addresses this.
Also, it tells me in the notification bar that the SD card is damaged or unsupported file type or something along those lines.
And for the record, I am running a stock Evo.

i welcome u guys to my world.i been having the problem since day one tried everything and nothing worked.fully rooted,new radio,tried few roms,formated SD card,put in a new SD card and still that random SD failure.i reboot about 3-4 times a day and its really irritating.im afraid i might brake my evo one day or jus claim for a new one.

This is how I feel

I'm tempted now to go back to stock and verify, but I never had a single issue on my phone until it was rooted. However, it's possible that the problem was there and I didn't encounter it.
If I take that step and find that it is still an issue on the stock OTA, I will most likely try to get the card replaced or have the phone if it persists after a new card.
It's very inconvenient and makes the camera pretty unreliable. Plus I am a field tech, and I store .pdf's on the card for different devices. If the SD is frakked I can't be sure I can get to important paperwork in the field.

It's not the SD card.I have already reformated the SD and even put a new 16gb SD card but same issue everyday.

It's definitely not the SD card. I've formatted it, gone to Best Buy and had the SD card replaced, and used a different SD card.
It could be the ROMs we're using, but I've got a serious problem with this phone if using a rooted ROM does this.. And few other people are experiencing the problem. That leads me to believe it's a hardware defect.

My suggestion jus get your phone exchanged ASAP.

Yeah.. I've contacted Best Buy and they'll let me know when they get their next order in

Unfortunately I am am outside my 30 day exchange period so I cannot do that.

Well, I hate to break it to you guys, but custom ROMs is not the issue. I am stock and have had my phone since launch morning (June 4) and today, for the first time, my SD card contents disappeared. I was changing wallpaper when the default wallpaper kept coming up as the wallpaper. Note that the when selecting a wallpaper, the gallery showed all my images (cached?) but when I went to Gallery, nothing was there. I pulled the battery to reboot and now the SD card contents are back.

I had the same thing happen with me. I've also experienced other strange things related to the card. When hooking the phone up to my macbook, sometimes files copy and sometimes they don't (to the card). I was thinking it was an app corrupting the card. I've tried large files (100-200mb) and small files (like apks or old video game console roms). It seems that when data is going to the card very aggressively, it doesn't wasn't to copy. What I mean by aggressive is like 2+ dialog boxes of files being copied at the same time.
More often than not, it seems like lots of small files pisses the phone off and it parts me back by bowling the card. Lots of files means hundreds to thousands.
I saw this thread awhile ago but didn't look at it until today. At least I'm not going crazy or even maybe have a bad card. The cards never gave me any problems with the devices its been in for maybe the last 3 years until last week.
I gotta find another card to try. I am using sandisk 16gb. Maybe a different brand? Anyone try that yet?
Sent from my PC36100 using XDA App

I'm doing a test now. I removed the suspect 16gb card from the phone and put in a 8gb card that has never been in the evo ever. I put the 16 in a sd adapter which goes into a usb adapter. All are official sandisk. I formatted the 16 in my macbook as fat32. I am now copying 8557 files to the card which size total is about 6.97gb. After a few minutes, I'm down to 6291 files to go and almost half way finished copying. I have not received one error message or anything that might lead me to believe there is something wrong somewhere. I'm starting to think there's nothing wrong with the card(s). It's the gd phone! I am so pissed now!!!! I keep looking back at the progress window and it's chugging along no problem. I am thinking about something tho. When I was changing cards I noticed that even when the card's lock bar was down, the card could wiggle a little. HMM. I'm gonna get a piece of thick paper and put it on top of the card and see if that helps make the card not want to wiggle as much when the lock bar is in place.
I will report back if I find out if it works or not in like 24 hours or less.
I don't think it makes any difference what rom you are running but I went to the one stock rooted "EVO_1.47.651.1_Rooted_stockrom.zip" one calkulin posted.

That link is just in case someone stumbles across this post later and wonders what I'm talking about.

So far, so good. I will give progress reports when I'm at work when I'm able to. I hope I may have stumbled across a simple fix to a defect.

I had the issue you guys are talking abou this is what I did to resolve my issue.
---------------------------------------------------------------
Just got a new SDHC card and simpleroot worked. The SDHC that came with my phone died. I placed a spare in there that was a 2gd regular micro and Hboot would not read the IMG for nothing.
If simple root is not working then it's the Sh!tty card acting up.
Happy ending for me.

For those who post before reading the thread, I am STOCK and this also happened to me. Battery out/in fixed the issue (for now).

So far I'm going on around 16 hours without the card screwing up. If you wanna try this, get a business card. Pull the card out of the phone. Lay the card on the business card at a corner. Measure about twice as long and normal width. Cut the business card. Fold the piece in half length wise so its the same size as the sd card. If it's too big, snip the non folded end of the paper and measure it so that its the same size as the sd card. Put the card into the phone and make sure its ask the way in. don't force it to hard. Then hold the card down and slide the paper, folded end first, on top of the sd and into the card bay. Make sure the paper isn't sticking out of the card well where the battery would be on top of. Gently push and lock the lock bar down onto the card. If you have to push firmly then the paper is too thick. Place the battery in the phone and put the cover back on. That extra bit of thickness added to the card I think is keeping it from scooting around in the sd card well and judging by the size of the contacts on the card, it wouldn't take much movement to get off the contacts. The folded end under the lock bar and the other end being held down by the battery I think is doing the trick. Just power down before removing the battery next time.
So far, this is working for me and I'm keeping my fingers crossed...
Just another update and bump off the topic...

I agree the ROM probably isn't the problem, but definitely come back and let us know if the paper helped at all. It could just be that the SD card is loose.. It seems like sometimes if my SD card stops being read, but I leave the phone alone, it'll work again later, without rebooting, which is odd.

[Q] Stock micro SD problem - undetected!

Hi everyone, I'm new here as you can see, and this is my first post here. Excuse me if I'm rude but I would like to get straight to the point.
So ever since I had my paws on the DHD (meaning since November), I recall dropping it three times (I know, I know! I have buttery hands). The DHD wasn't affected at all in the first two drops, however the third drop caused the micro SD not to be detected, which I promptly removed and inserted, problem solved.
However, 6 days after the third drop, meaning today, when I was charging my DHD, the phone reported that the micro SD had been removed unexpectedly. I tried removing and inserting it but it still reported the SD as not inserted. I took it off, put it in my reader, and my Windows could not detect the card - it's like it doesn't even know a card is in there.
Tested the reader on my bro's Mac, still not recognized. The problem is definitely with the micro SD as other micro SDs I tested can be both recognized by my computer AND the DHD itself.
Also, I think it is interesting to note that when charging the DHD, the battery temperature would go up 5-6 degrees. A quick glance at Google says overheating of a phone could very well screw up a memory card.
What I want to ask is, do you guys have any idea what happened to my memory card and whether there is a way to recover what's inside? They're not really THAT important, but it'd be nice if I can see my photos again.
Thank you for any response! They're much appreciated!

Just tried putting it in the reader again - no such luck.

Try to see if this post can help, it worked for me:

It sounds like you managed to break the card, i would recommend buying the cheapest micro sd card you can find and trying that. If it breaks then it confirms its a problem with the phone. You could try sending it to HTC under warranty if its not too obvious that its your fault....

Constant "sd card was unexpectedly removed" errors

Ok so this started happening when I switched to unofficial CM9 from this forum. Constant "your sd card was unexpectedly removed" errors. Usually right when I open the camera app, or try to play music. Go figure. Once I reset the phone (doesn't always work) the problem goes away until I leave the phone long enough for it to go idle I guess. First thing I figured was the OS change. So I restored a backup. Same problem. Backed up the sd card and wiped the phone and sd card. Reinstalled CM7.2. Nope. Same problem. Forgot to mention, I had already tried both of my spare 16 gig cards, two of which were from a different manufacturer. One I formatted with my computer, then other I left alone and just deleted the files from it with the phone to rule out my computers card reader going bad. Both had the same exact issues. I even switched to a sense based rom called UKB. Same. Problem. Although this time it seems to be a little better. Worked all day yesterday at least, problem only coming back after the phone was on charge all night. I could live with that but I doubt it'll keep that up all night. I've read just about every forum post on every forum. Loads of people suggesting reformatting without using quick format, formatting with different settings, using various apps that change the cache size. Regardless, none of this was necessary before, and definitely shouldn't be necessary now. I'm a couple months past my warranty or I would get a replacement like I did before when I had headphone jack issues. Really sick of my phones all going bad before upgrade. Maybe if I called they would see that I have not been a happy customer, but a customer nonetheless since like 1998. Who knows. But anyway, does ANYONE have any suggestions? And please don't suggest going to settings and hitting mount. That suggestion is in just about every forum post about the problem and it oddly drives me crazy. Probably because of how obvious it is. That option is always greyed out of course. Thanks in advance to anyone who's willing to help. I always want to smash this phone every time I need to take a picture of something really cool and my phone decides to act up.

Come on guys, nothing?

I'm having the exact same problem, and I'm 100% stock, always have been. I have no idea what's going on, but it's really frustrating, especially because of all my apps I keep on the SD.

Well the best part? Now the phone doesn't recognize the card at all. This phone has been in a case since purchase. Never been dropped. Has been tested with multiple cards in multiple formats. But looks like HTC is yet another company that designs phones to intentionally break over the course of a year or two. Go figure. Phone is only a little over a year old. Then again the board is older since it was a refurb. First phone had issues with the headphone plug.

Haha that one made me smile. I can just see myself in the dark with one of those long armed desk/work lamps shoving an sd card into my phone and yelling "SURPRISE!" while laughing like an evil villain. This truly has driven me nuts though. I've been stuck on my sad old OG Droid. You know, the one that made android popular but is painfully slow when you're used to a phone overclocked to 1.5 ghz. Even with this one at 900 mhz (all it can handle with a standard voltage kernel without crashing) it often freezes up multitasking. Navigation takes a good couple minutes to fully load a small route, and it simply isn't gonna happen if music is playing.
HOWEVER, I decided to try again. Dinc2 recognized a card again. Not sure why. Whatever. So because the card works even temporarily, I flashed a new radio and am now downloading unofficial cm10 and all that good stuff. Gonna flash everything after triple wiping, then I'll wipe cache again after flashing everything. Just maybe that new radio and lots of murdering the wipe button, it shall survive. It just doesn't make any sense to be a hardware problem since it's only intermittent when the sd card is suddenly active after not being accessed for some time. I can sit there taking pictures and video for hours while playing music. But once the screen is off for 10 minutes and I go look at those pictures, the sd card is suddenly removed. I'll keep you updated. Downloads are complete. Muahahahahaha

So I did end up flashing CM9 instead, because CM10 was just too buggy for my liking. However I used the newest kernel available. It was in the unofficial CM10 forum post.
Radio seems to have fixed the problem though. SD card hasn't unmounted once. We'll see how it works out over the course of the day but it copied all my music over wifi last night, finished at about 2AM, then sat there until I woke up at 6 completely idle. Picked it up and went straight to gallery, and it loaded pictures. Took a snapshot with the camera, then played a song. Everything looks to be in order. I flashed the radio that was apparently in the leaked ICS developer update.

Disregard the suggested fix I posted prior. I mean if you have the problem you can try it... since it seemed to fix it for a day. But it's right back to it again. Downloaded and installed ukb evolution 2.1, and it did the same on that as well. So I guess I live with it for the time being, never buy an HTC device again, hope like crazy a moto device lasts longer, and fork over the scam of an extra year of warranty when I upgrade. Really, what kind of world do we live in where we have to spend money for a company to stand by their product for longer than a lousy year? When standard contracts are for two years, it leaves an entire year where the device can just stop functioning properly, like this one, and then you're stuck paying 600 bucks for a device that cost HTC maybe 100 bucks to make. And even at that ridiculous cost, it still takes two iterations of android before they even suggest that they might update the device to the older version, over three years after launch. Awesome little fact, if the one year warranty restarted when I got the phone replaced in the first place for an issue with the headphone jack, I would still be under warranty. But nope, it wasn't replaced with a new device, but someone elses phone that was then fixed and then sent to me. I still hate that I can buy a brand new phone, and get a used one in return because these companies refuse to build a phone without trying to design it to die at the end of it's "useful" life. People will pay to upgrade if they want to. If the phone barely lasts the full two years if that, someone in their right mind simply wouldn't buy from them again. My original droid was out of warranty by 8 months when I had it replaced TWICE. Why? Because I had it replaced 5 times before that for headphone jack problems. Only reason I didn't buy another moto phone was because they decided to lock down bootloaders for good, while HTC was announcing that they were becoming dev friendly and unlocking their devices. Customers always get screwed. Alright end rant. Sorry guys, extremely frustrated.

I had the same problem on the Samsung Galaxy Y Pro, FWIW. Probably unrelated.

Same here with a 2 year old dinc2. SD card works fine as far as the phone is awake. Works fine in other phones and computers either...

Every 6-12 months, I have this problem and it's blindingly frustrating. As it turned out, my MicroSD card was starting to get tired, and swapping it out with a brand new flash card from Staples resolved it completely. Just like the OP, I had two used 32GB MicroSD cards -- one of them an expensive high-speed Sandisk -- that reported no errors under Windows or CWM. Installing it in my DInc2 (CM10), it would run for a while, but then just decide to unmount.
It may sound illogical, but try purchasing a new, inexpensive MicroSD card (I bought another Sandisk) and see if the problem goes away permanently.

I tried two different sd cards on two different roms - cm7 and evervolv and the cards kept dismounting about twice a day. I then turned on "protect sd card" under developer options on evervolv rom. I don't know what it does but haven't had the problem for about a week. It might be a coicidence though. Will see...

I had the same problem for monthes. I had gone through all the efforts to fix it. finally I found a clue.
On the back cover, there are two pairs of pins which supposed to connected to the terminals on the phone, which are not connected well. so I bent the springs up a little bit and made connection well. (be very careful not break the springs). then SD card show up right away. It's being working for days and no more problem.
hope it helps everyone.

My dinc2 started with this problem about 3 months ago. I was running the psychochilly cm10.1. Then I decided to try the miui v5 ('alpha'?) rom which had a known bug that the SD card won't Mount. After about two minutes, it crashed, so I just decided to restore my psychichilly backup. Thenextday i noticed that the sd card was unmounted several times when I wanted to take or look at a pic. I found that if I took my otterbox off, along with the back plastic and tapped the back of the phone near the bottom on the edge of the table gently it would magically recognize my SD card. Not too long after it would pop up that 'SD card unexpectedly removed' message. So. Whether it's hardware or software related, I'm not sure. But I'm thinking hardware. On the other hand, I had to use the tacoroot method to s-off. Maybe an effect that took a whole year to happen. Either way I think the only way to fix this issue, besides reflowing the motherboard around the SD card slot, is to replace the motherboard, which I just might do. Kinda itching to flash the new PAC.

If the card is seated securely and you are getting those errors sounds like a defective card.
Have you tried a low level format?
Have you tried other phones, devices?
If so do you get errors on those also?
Have you run any test on the card itself. Are you sure you are not mistaking issues with the new SD card permissions (or lack there of) for errors?
Those are some of the steps I suggest to figure out if the card is bad right out of the box, yes this happens a lot more than you think it does, or that card don't play nice with device this still happens even though it should not, or the card is on its way out. If nothing seems to be working try and get a replacement that should fix your issues and if it don't, don't buy that kind of card anymore

I have never had a issue with SanDisk but is the luck or unlucky of the draw[emoji1]
Formatting many times is no good for SD cards should really only format when you HAVE TO. There is really no need to format reformat... Usually after some time of using the card you can get back some lost performance by performing a low level format. But again really should only do that when you NEED to.
I have the Pro version (the Grey and more expensive one) Samsung card you have listed, I love it as far as performance and what not but I use it quite often for various devices not only in the N4, but for many people an expensive high capacity high performance card will be pretty much a waste (at least until root comes our way). Many people can survive on the devices memory alone, if I had to I totalaly could without any issues. Most things are streamed/synced/cloud and whatnot so there is no need to have a large amount of things stored on a SD specially when you take into consideration the new android sdcard permissions. Only system apps can even write to the card, no normal apps can.
This may change down the road hopefully, Google will be persuaded into changing that policy, or at least once we have root we can make our own rules.
Unfortunately Android has the stigma of being the "Least Secure Mobile OS" and I think Google is going to move in the direction trying to rectify this. That is going to be unfortunate for us I believe, because technically the statement that Android is the least secure of the mobile os's at this time is true. If the user knows nothing about computers, software, Linux and whatnot then yes this is true. But for many of the same reasons Android is considered vulnerable are the reasons the advanced user loves Android. Unfortunately I think many of these things are going to change and the advanced users will be stuck with solutions to problems we never had in the first place because the vast majority of people need there hand held in everything they do. LOL sorry about the rant but above that is my 2 cents of your card question.

I had the same problem with my Note4. I suspect this to be the cause of my recent problems with IndexService.
The last days I noticed an extreme batterydrainage. (50% in 4 hrs only cheching mail and reeding some ebook and newspaper) 44% usage by IndexService and 17% by screen.
At first i thought it was my Next UI . Deleted it . No changes.
Then I found out about similar issues on S5 and note 3 to be caused by corrupt pdf files. I deleted all documents, pictures, ... everything! Nothing changed.
i took out the SDcard. The same or even worse. Keeps the phone checking for SDcard when none installed?
So I reconnected the SDcard and formatted it again. STILL NO CHANGES.
Suggestions anyone?

Formatting many times is no good for SD cards should really only format when you HAVE TO. There is really no need to format reformat... Usually after some time of using the card you can get back some lost performance by performing a low level format. But again really should only do that when you NEED to.
I have the Pro version (the Grey and more expensive one) Samsung card you have listed, I love it as far as performance and what not but I use it quite often for various devices not only in the N4, but for many people an expensive high capacity high performance card will be pretty much a waste (at least until root comes our way). Many people can survive on the devices memory alone, if I had to I totalaly could without any issues. Most things are streamed/synced/cloud and whatnot so there is no need to have a large amount of things stored on a SD specially when you take into consideration the new android sdcard permissions. Only system apps can even write to the card, no normal apps can.
This may change down the road hopefully, Google will be persuaded into changing that policy, or at least once we have root we can make our own rules.
Unfortunately Android has the stigma of being the "Least Secure Mobile OS" and I think Google is going to move in the direction trying to rectify this. That is going to be unfortunate for us I believe, because technically the statement that Android is the least secure of the mobile os's at this time is true. If the user knows nothing about computers, software, Linux and whatnot then yes this is true. But for many of the same reasons Android is considered vulnerable are the reasons the advanced user loves Android. Unfortunately I think many of these things are going to change and the advanced users will be stuck with solutions to problems we never had in the first place because the vast majority of people need there hand held in everything they do. LOL sorry about the rant but above that is my 2 cents of your card question.

no and i agree with you regarding your rant.. it's just sad there is no recognition for the hardcore base user group.
So i think i'm gonna bite the bullet and buy the pro... I've done some more research and it seems that specifically the Ultra 64gb sandisk card manufactured a year or later ago has a technical 'fault' according to sandisk. i don't care for another sandisk so i'm gonna just buy the pro...

although i feel exhaustd with sandisk.. there is a 64gb extreme sandisk microsd ...
how is the quality of the extreme cards compared to the samsung pro?

I had issues with my 64g SanDisk ultra when I got my note 4. Worked fine in my note 2 until I moved it to my note 4. Then I started to get the SD card unexpectedly removed, constantly remounting. Formatted it in the phone in the computer nothing worked. Couldn't even copy back the stuff that was on it. Purchased a PNY 4k compatible micro sd and it works great. I will never get another SanDisk.

Question problem with "sd card removed unsafely" notification

hello, can you guys help with this issue? looks like it is not just an A72 problem, but also on other models.
the notification is very frequent, and happens even while the phone is on standby.
what i tried so far
a 128gb sandisk extreme pro (old phone)
a 64gb sandisk extreme (gopro and camera)
a 64gb sandisk extreme (brand new)
a 32gb samsung evo plus
also
restarting the phone
unmounting the card and restarting the phone
physically removing and card from the phone and putting it back with phone shut off
removing the card and error checking it (in windows, using a card reader) then formatting it
formatting again on the phone
getting into the recovery mode and wiping the dalvik cache
full/factory reset

An SD card was removed unsafely. To prevent your phone from restarting... notification
Ever since the big update to Android 11 / One UI 3 I've been getting the "An SD card was removed unsafely. To prevent your phone from restarting unexpectedly, save unsaved data and restart your phone" notification, many times a day. After the update and prior to having this error, I have not...

Receiving the same notification with Samsung Evo 128 GB. The only solution I see as of now is to report the issue in Samsung Members and wait for a bug-fix.

Thanks, After doing 2 reports they told me to get my phone checked at a local samsung service. Seems like they are denying that it is a software issue. I really hope everyone reports it because it doesen't look an hardware issue to me, and I have difficulty on sending it to a local service...
edit. they are DEFINITELY asking me to look for hardware issue...

I have never gotten this notification on my A71 and A72, and I'm using an samsung evo.
Be 100% sure, that it's not hardware fault, before assuming it's the software. Is the SD card really locked in the tray? It shouldn't fall out when rotating the tray upside down. And there should be no dust in the tray also.
The golden connectors on the sd card needs to be clean too, make sure there is no fat/dirt on the golden connectors.

I assured all that. I even cleaned one of the cards with a rubber then gently rubbed with a clean pieceyof cloth. Today I'm getting a replacement and I will try that. It seems weird that other people around the world are having the same issue after Android 11 update.

The same error here, on a A72. I will wait for an update from Samsung and report it as well.

Same error here on the A72. I have a 512GB Samsung Evo Select (purchased directly from Amazon a couple of months ago) and it was working perfectly fine in my S20 FE but when I put it in the A72 it started giving me the error messages, even when I'm not accessing the SD card. So annoying. I'm convinced it's a software bug. There's a few with this phone. Updated it yesterday and on 30x zoom it actually saves the photo as if it were taken on 20x zoom, so the framing is way off.

for some reason the new unit didn't have the problem.. BUT it is under repair now since it had stuttering while recording. it also had a bad vibration motor (looks like they are not replacing that...) they are replacing the motherboard so who knows.. i think i'm gonna ask another replacement after the "repair"(they couldn't even reproduce the issue and they are changinh the mobo just because...) seems like quality control on samsung side is really poor. at least on middle range phones.

Do a low level format with a 3rd party app (not Windows) on the card.
Let the phone then format it.
Then load the data to the card while in the phone.
I would say if it still does it after that it's the phone ☠firmware☠
I don't update firmware if my OS is running fast and stable (hint)... and don't have any issues
Still happily running Pie...

i did that many times. one a72 had the problem, another not. but now i'm having the mobo replaced, so who knows... the same sd cards working perfectly fine on one and giving back the error on the other one... many other users are reporting the problem on the official forum for a72 and a52... never updated anything, came like this right out of the box

That's sounds very aggravating.
Hope the new mobo fixes the issue.

guys.. this is incredible... i went to samsung local service and they replaced the motherboard because i had an issue with the video stuttering while recording (NOT the sd removed issue)
guess what? after the motherboard was replaced i started getting the sd removed notification! i think there is a big flaw in the manufacturing process and it may be an hardware problem... i'm trying to get a THIRD unit and see what happens... i really don't know anymore...

update
for some reason i stopped getting the message. on the repaired phone and on the new one. may be the april update, or not (on the official forum other people with the same update keeps getting the error) but at least for me this is fixed (the phone has other issues tho...)

Having the same issues with an A52 5G.
See:
SD Card Issues
Well just picked up my new A52 5G really enjoyed it at first but now my SD card keeps getting unmounted every time I restart the phone. ( The best part about this is the SD cards are made by Samsung tried 2 different ones both are 128G) (SAMSUNG...
forum.xda-developers.com

After the last update i didnt get the notification again, im using sandisk ultra 64gb

I haven't seen this message for some time now, and for a reason I didn't want to bring it up
Hope they have solved it with an update, but it would be honest and brave if they had admitted there were issues.
Just ignoring the many complaint in Samsung Forum is not a good thing to do.

To ALL here...I too have been getting the same message with my new A72 & the unseated SD card - multiple times throughout the day, to the point I have to carry the opening pin with me. I've only had it 5 days now.
The problem is the flimsy cheap plastic tray - it's not a software problem folks.
I have found just pushing the tray in unseats the SD card.
I've also experimented with flexing the tray slightly verses just pushing it straight in...no difference - the top of the SD is unseated no matter how I push it in. Holding the SD doesn't help either
It must be constantly checked as I push it in slowly, checking & rechecking the SD. I have noticed it is constantly unseated all the way in. Once I get the tray carefully to that last point where it's mostly inside, I push it in quickly & restart the phone...it may take a while but invariably I get the dreaded message again...& for seemingly no reason - I havent dropped it but maybe it's just a vibration it doesn't like, like putting it down a bit roughly!
I'm taking it to my local samsung store today to see what they have to say.
Not good enough. We need a stable non flexible tray... full stop!!! I'll post again when I talk to them...

Try using a spacer like thin cut pieces of tape under or on the card. Holder or card may be out of specs...

As per my post last night the samsung store guys were surprised by the issue.
That did suggest sending the phone to samsung for analysis & then if the tech says it is a flaw I take it to the seller for "repair"
I doubt samsung will replace the tray with a better one though & frankly don't want to give my phone & all its data up...
I'm going to try taping the SD in place with a clear 'sticker' & see it that works!
