SD Card keeps becoming unavailable

Has anyone else come across the problem where the micro SD card seems to just stop being available to the phone? I'd say maybe once or so a day, anything that reads data from the SD card, such as the music app, stop working. If I try and play a song, it just hangs and does nothing.
I tried a search and somebody in the G1 forum had a similar problem but it didn't really contain any conclusions on what it is likely to be.
Anyone else had this issue? What is it most likely to be, the phone or card?
Thanks.

yeah I've had this occasionally with the camerea and seperately the 3d gallery software I installed.. have no idea why

Yea I've had that a couple of times actually. Just have to turn it off and on again and its ok, but its annoying.

Yeah, rebooting does sort it out, but it's starting to happen every day now, sometimes a couple times a day. If it's just a dodgy card or whatever I'd rather get T-Mobile to sort it sooner rather than later.

hmm a dodgy card.. included with the phone, that sucks

Backup your SD Card data and then try formatting it to see if that helps.

Cheers, will give that a go tomorrow. I might ring up T-Mob tomorrow anyway just to make them aware of the issue I'm having.
If I format it, will I be able to copy all the contents back on to it?

Yes, back it up to hard drive on your PC, then after you have formatted your SD card, copy back the contents from the hard drive to your Removable disk (SD card).

I've had this a few times Took the card out, reinserted and restarted the phone. Seemed to fix it, but it is annoying.

Sorry I can't remember when and how I know this.
But backup the card on your PC
Then format it in/with the phone and this should solve the problem I believe

I had killed one of my 16 GB card in Nexus one.
I found a problem that if i use Win 7 or Vista i must remove the device by using safely remove the USB device. Since now am doing this way i never had any problem.
Word of warning you could simply kill a card if you just remove a device.

My first thought was it has something to do with the USB connection. If you safely remove device in Windows - the phone 'prepares' the SD card.

I was having the same issue. I connected to the PC and mounted the SD card. I performed a disk check on the card and it found some errors which it then repaired. I then unmounted the card
I haven't had any issues since.

I formatted my card yesterday and haven't had any problems so far. thanks for the advice.

I ended up replacing the card. All of the previous advice didn't work for me or if it did it didn't last. I reckon there was a bit of a dodgy batch supplied by SanDisk.
~Since replacing I've had absolutely no problems whatsoever, it used to happen at least every 48hours. Very annoying when you try to take a photo and it tells you there's nowhere to save it.

I've been having problems too when taking pictures, which is really annoying!
And i'm not sure whether this is a related problem or not, but it could be...when trying to receive a file over bluetooth it sometimes says it doesn't have permission to receive the file or something along those lines, could this be the SD card playing up?
I'm on T Mobile, would they replace the SD card?

Not sure if it is the same reason, but I had all kinds of problems including the one you've described.
I'm on Orange, they told me that my SD card wasn't covered by Orange Care (the orange phone insurance). I said I didn't have Orange Care anyway and that surely it comes under the 12 months manufacturers warranty. They said pop it into the shop which is a bit of a drive and would cost me more than the value of a new card to get there.
At the time I wasn't certain it was the card as I didn't have a 2nd to try it with. Given my problem was very intermittent I decided the bother of going into the shop - it wasn't worth it for a £5 card. Now that I've bought a new one that works perfectly, I'm going to head into the shop with the old one next time I'm passing. The problem is I don't really need it replacing now! You could always lie and tell them you've tried your friends card at home for a couple of days and it worked perfectly?! No harm in trying.

Mhh - maybe I've had luck, but I use my over 1 year old 8gb cl6 card from magic/mt3g and never use that win function while unpluging anything (not while data transfer). So maybe depends on quality or manufacturer?

2-3 weeks since I've formatted my card and now I'm carefully unpluging my phone only when it's charging it hasn't happened ever since

I hate to say it, but it will happen again. Have card reader or other phone prepared, just in case your sd card stops working totally

SD Card seems to be unmounting automatically...

Well, basically as the title says. This's happened several times to me already. Say I'll turn my phone on (from standby) I'll get a popup error saying that the backup was unable to complete because no SD card was found. Next, the music application won't load the songs because those're all stored on the card. Same for Photos/Gallery. When I go to ES File Explorer, the 'sdcard' folder reports that it is empty.
There hasn't been a pattern that I discovered. This just happened now when I woke up (phone left charging overnight; Wi-Fi & Sync enabled) and I decided to come post here. Happened again yesterday afternoon when I got my phone out to play some music on the way home.
Every once in a while, I'd get lucky and the files would show up by themselves, but the only fool-proof way I've found to get the phone working properly again is a restart, which takes several minutes to do.
I am NOT running any task manager (well, I was but when this problem started up I checked another thread which recommended to remove the task manager, so I did).
Is anyone else experiencing this problem? Do you know of a fix, or is it just me?

Mine's done this a couple of times, but I've put it down to the SD card not being quite pushed home properly. Worth taking it out and cleaning the contacts.

Nope, that doesn't work. I re-inserted it yesterday (contacts were clean) and this morning woke up with the same problem.
Please tell me this isn't just happening to me, cause it'll be a right pain in the ass to have this repaired (sending abroad/etc).

Is the SD Card the one you got with the phone (4Gb) or another make/model size? Please include details so others can help more.
I have left the given Samsung Class 2 4Gb SD card in mine and I have never had any issues with the SD Card unmounting. This is not saying it won't happen, but for me it has been fine. I was going to upgrade to my other Sandisk 16Gb Class 2 that used to be in my Touch Pro, but will do that hopefully this evening.
So all I can guess is either a faulty card or some issue with Class/Size/Manufacturer of Card (if you changed from the Samsung one) ?

It's the stock 4GB card that came pre-installed in the phone. Phone's unlocked too, bought from Clove. If it helps/is relevant: when I loaded up the camera it gave an error saying something like 'no sufficient read permissions for SD card'*, maybe that'd be a clue to the problem.
*I can't quote exactly cause I've since restarted the phone and can't remember it word for word. If/when this happens again I'll post the exact error.
EDIT: There, it just happened again. Restarted the phone not even an hour ago, it's getting ridiculous. Anyway, the error from the camera reads "Unable to save file to SD card due to insufficient file permissions".
FWIW, when I go to SD & Phone Storage settings i CAN see the total and available space on the card. It's just completely inaccessible by the programs. Have also tried the 'SDMount' widget, did absolutely nothing.

Happens to me too but only when I've been letting go of my phone to put it down rather than placing it down, or if I have to drop it on my bed or chair quick.

Happened to me a lot too when I was using one of the lock screen info apps, to get my calendar info on the lock screen. Uninstalled and the SD card problem went away.

Never used that :/
I've uninstalled all apps that seemingly access the SD card and will start reinstalling one by one to see if the problem does come back. Only way I could think of.

It is happening to me also. The last 3 days is doing it at least twice a day , i have the desire almost one month and neved had this problem earlier.
And i though it was something i did.

i had the same camera permissions problem. restarted and havnt seen it again since. 4gb card that came with the unbranded device. no idea what caused it, could be any number off new apps etc :S

I've got the same problem.
I've already tried to reformat my SDcard, but the problem still exists. Another problem when the SD card unmounts, is the CPU usage. This rises to ~10% constantly. Probably cause of this are apps which are trying to write to my SDcard.
Still no solution found, maybe I'll try another SD card in a couple of days.

FWIW, I gave up on the stock card and copied all my stuff over to another 4GB card I had running around (straight copy) and it seems to be working fine now. Haven't had a problem yet, although it hasn't even been 24 hours.
Will report back if/when something comes up, and when I start re-installing the apps that I previously removed.

I wrote to HTC earlier yesterday describing the same problem, and I just received this reply:
Dear Mr.Matthew Thank you for contacting HTC. Maybe you mount it on the pc to copy nd paste something and you forgot to unmount it from the pc.. Are you using the inbox SD card? Did you install any third party applications to the phone? Please use the phone in Safe Mode. Safe mode terminates all installed running applications, in case if they caused this issue. Please backup what you have on the SD Card and Format it. If you have any other inquiries, don’t hesitate to contact us again. Please note that you can contact us via support line. For further details, please go to http://www.htc.com/europe/CA_Hotline.aspx , Thank you so much for using HTC products. Respect & Regards, HTC Team http://www.htc.com

Only thing I have not yet tried is the Safe Mode. Will see if it needs to get to that.

i had this issue when I installed 'ebuddy'... uninstalled it and the problem is no more

It's started to occur on mine at least twice daily now, it wasn't so before about 4 days back. I've just actually restarted the device on getting such an error and apps complaining that they can't read/write to the SD card. Really after some sort of fix here.

You're right it seems that was my problem too.
I got rid off ebuddy and all is fine now

I've had this problem once so far, and reading the reply from HTC reminds me that I have unplugged my phone from my mac without unmounting it a few times...

I am also having this issue and have ebuddy installed! I shall uninstall it and see if it fixes it! I really hope it does because its starting to get annoying

I too have ebuddy installed and shall also try removing it and see if that fixes it!

I don't have ebuddy installed but just experienced the SD card error with the camera today.

SD card stopped writing

So this started Friday morning but I didn't know what the issue was. I use my SD card for caching music from my All Access Google Play music subscription, and I was actually streaming non-downloaded music at the time, and everything stopped working, and I kept getting errors about not being able to download. Didn't think much of it. Did the standard Routine, reboot, didn't work, so I cleared cache and uninstalled updates on play music and the service was working again and I didn't think about it again until I tried to take a picture later in the evening and got this in the gallery instead of the picture
http://forum.xda-developers.com/attachment.php?attachmentid=3418912&d=1437899706
Again I just did the standard stuff, rebooted, cleared cache and data to the gallery and camera app, but this time nothing was working. I finally decided to change my save location from my SD to my internal storage, and my pictures started saving again. So I connected the dots to what happened with Google Play Music earlier in the day, and checked my downloads, and nothing was downloaded anymore, option to save to SD was grayed out. Naturally I tried to format with the card in the phone, and it acted like it worked ok, but still showed I only had 11gb left of space, and still wouldn't work with anything. So I stuck it in my PC, and windows errors every time I try to format it. I tried with the default windows 8 formatting tool, I've tried with third party tools, same thing, won't format. Card appears to be read only now. How does this happen? It's the free 32GB card I got from LG with the extra battery and charging case I got for buying a G4 before June 30th. In fact I've only had this SD card for maybe a month. Is this some lolipop permissions keeping me from formatting it or is it hosed? I remember reading something about Google changing permissions on the SD with kitkat, but I also read they changed back with lolipop. I also read that LG didn't seem to notice they changed back and kept things the way they were with kitkat. If that's the case how do I take ownership of the whole card so I can format it?

I've had the same problem!

I have no idea of the answer yet but if I find one I'll let you know. But this has happened to 3 different micro sd cards in my LG G4! I don't think it's an android issue I think it's an LG g4 issue. But I'm going to investigate further. Brand new sd cards working fine for a few days then rendered read only and unable to format even on a laptop!

This literally just happened to my 32gb card received with the bundle. Any update?

I had the same issue with a A-Data 128GB UHS-U1. After a month of usage it wouldn't mount on my phone. After trying to format via various means (Disk Management, Partition Magic, SD Formatter) I found my card was set to read-only and nothing would change that. I've had very good experiences with A-Data before so I chalked it up to a manufacturing defectand filed a RMA on the lifetime warranty. Ive got a spare 16GB popped in to see if it's the phone doing it (Also A-Data)., I hope its not the G4 because I love the phone. But if it is I'm not wasting another SD Card and buying another phone.

Sounds like a corrupt sd card somehow.

I have the same issue with a SanDisk 200GB Card as discussed here:
http://forum.xda-developers.com/g4/help/phone-upside-screen-off-t3227335
So it's the G4 that is killing the cards?

It's one of 2 things: Either manufacturing defects (which seems more likely) Or a G4 issue (In this case I would expect the issue to be more widespread then the low number of posts). The solution for some seems to be repartitioning the SD card, in my case though it reverts back even after the partitioning, SD Formatter indicates its stuck in read only.

It can also be some of the cards don't work well with the heat the G4 generates. On mines, it doesn't indicate read only but it seems I can't format or write to the card but I can delete from the card fine... I just tried SD Formatter and it basically shows what's attached, I thought only full size SD cards had the write protect switch, is there any software that can make the card write protected or not?

That's the exact same error message I got with SD Formatter, You could try with using partitioning software to see if that works, it was a no go for me. Regarding the heat, that could be an issue too, compared to my previous phone, the G4 runs really hot.

Any Partition software you recommend at it seems MiniTool Partition Wizard doesn't recognize etxfs as a filesystem. The G4 does run pretty hot, so much for the claims of the cards claiming to be resistant to everything...

I did try the Windows Disk Management Tool, but even that can't fix it. Well to be fair, no phone runs as hot as the G4 from my experience, guess LG still makes crap...

Has anyone tried the sd card fix floating around the g4 forum...it's posted at least once in the threads by micromod777 in tmo g4 forum...also to those with unlocked bl have you tried formatting in twrp?

Happened to me too. (SD from promo) I had to replace it. Nothing can be done about it. SD is trashed.

LG aka Lucky Goldstar had always been a low-end brand. The only reason I've switched from Motorola is because of the microSD slot and the removeable battery. Samsung's are more for looks too..

Got a link to the sd card fix?

Some good news, A-Data notified me that they be replacing my micro-sd no strings attached. Sad news is that I'm tried of hardware issues on Android devices. I considered the Moto X Pure and the Nexus 6P, but being a Canadian, I'm getting royally shafted by exchange rates, ended up getting an iPhone 6s.

Same exact issue here with the 32gb card I received free from the promo.

I got ahold of LG and they replaced it. I bought a much nicer sandisk uhs 64gb card while I waited and when the replacement came I put it in the wife's gs5, that was 3 months ago and it's still working so hopefully it'll continue to work

I really think there was something wrong with the previous firmwares. My play music would wipe at least once a month and reading off the card was always sluggish. Ever since the 81010o update everything is fine, and I can take my card out and reinsert it and play music won't delete my music. Unfortunately I believe the previous firmwares were killing cards too

SD Card not being recognised

Hi all,
Euro LG H815 running V10b.
I have two good SD cards here - one is FAT32 and has a ton of media on it and one is FAT with just a text file on it to test with. Both show on a PC and both mount fine on a Galaxy S3 and operate well, however neither are showing on my G4. I literally have the SD details greyed out within the storage settings on the phone's menu. No amount of inserting/removing/reinserting and rebooting appears to have any effect.
I'm away on holiday at the moment so not much I can do, but before I try a hard reset and consider sending it back to LG when I return home, is there anything glaringly obvious I'm missing or anything I can try?
I have no apps disabled, not rooted and running all stock.
Thanks.

Has the phone ever recognized an SD card, or is this something that has changed? The cards are facing in the correct direction, are fully inserted, etc?

Hi mate - thanks for the reply.
Yeah, when I first got the phone a few weeks ago I gave the SD card a whirl and was pleased to see it presented well in the settings and all the media played with no issues. I tried it just that once and until today, haven't tried since.
I'm placing it in pins down with the branding/lettering facing up. I have just had the port under a light and magnifying ring and as expected, all pins are fine.

Completed a hard reset, still no SD card.

I have not seen that, sorry. I don't have any suggestions except to contact LG. Hopefully someone else will have some insight. Good luck.

Thanks. I think it's going to be a return.

Lg G4 in bootloop, how do i get files off of the phone?

This is my father's phone, he has already called verizon and they are going to send him a new phone, but he has to send this one back. I would like to get all of his photos off of this phone before we have to send it back, but it is in a boot loop and there is no TWRP installed to my knowledge, only the stock "hold volume down and power" restore options.
Is there anything i can install or something that will allow me to get anything off of the phone?
(btw it is not rooted either, my father is almost 50 now and he doesnt play with technology like i do)

I used this method and it worked perfectly

My G4 had a bootloop issue once.. turned out the problem was related to a corrupted sdcard. Once i had removed that then everything was OK and it booted up just fine. This might be worth trying if you haven't found a solution yet.

Mr. Crusty Genius: You solved my bootloop problem! By removing my SD card, the phone now works flawlessly where is was bootlopping with the SD card in.
My question, however, is what do I do now? I tried reformatting the SD card (after copying files to my desktop), and as soon as I put the allegedly formatted card back in the LG, back to bootlooping I went.
What would be my next step? Say "f" it and get a new card? Leave the card out? Or fruitlessly try to contact VZW and/or LG. This irritatingly enough happened THREE DAYS beyond one year since purchase.
90% of what is said here is Greek to me, so if you could use small words, it would be appreciated The phone isn't anything except off-contract. Using the way it came in the mail one year and THREE DAYS ago.
Cheers!

Hi
Yeah so in my case all I had to do was format the card and then stick it back in and problem solved. If you've already tried that then I'd try a new sdcard!

I was told by multiple people that the G4's defect of bootlooping issues is hardware related. Phone gets to hot and it causes a tiny solder point to break. Requires a new mainboard.
This is why I want an SD card....every possible piece of my data I store on the SD card and not the internal memory incase phone itself is not usable. It has saved me a fe5w times. Really want a Nexus phone, but no sd...so....yea...and they don't make a 200gb+ model.

The one thing that worked for me was putting my phone in the freezer for 15 minutes and then booting it up while still in the freezer. I also read to turn it on airplane mode after finally getting it to boot up so it would not slip back into the loop defect. After getting it to boot I immediately plugged it into the computer and switched the USB charging setting (in the notifications when connected to a computer or laptop) to Meida sync and then using the file explorer to go into the internal files of the phone and moved all of the pictures off of the phone onto my computer thus saving them. (your camera pictures will be under DCIM)
