I've been using Optimus one for the last 2 months and i've been facing SD unmount for a month now. And now out of no where, the device suddenly goes dead, gets stuck, and the "android" boot screen comes up.
Any one else experiencing this problem? And this occurs only when GPRS is on!!
Please share if someone knows the reason or a fix for this issue!
And the unmount is quite bugging.
Do you use the stock rom v2.2 ? I had this problem too, then upgraded to v2.2.1 and the problem disappeared.
This is mostly caused by low class SD Cards. Get a class 6 SD and it should work perfect. I had the same problem too. Cheap SD cards are always the problem .
The GPRS thing is just a coincidence in my opinion, but it can be an error due to the crappy SD Card (and the conflicts it causes in the os) too.
BTW, i dont recommend upgrading to 2.2.1, it's somehow slower and no major bug fixed. You may consider going on Void, or maybe stock but with mik_os kernel - it fixes the painful touchscreen bug.
If the phone still isn't rooted and running without a custom recovery, the best thing to do would be to get it to a service center.
I still haven't rooted my phone! I tried doing a factory reset today and i haven't had an unmount since. And i guess it is the SD card. I have a class 2 Transcend. I never realised the class made a differnce. And I dont find an SD beyond class 4 here in Chennai. Any place online where i can purchase?
And would this also solve my auto rebooting issue??
mine also reboots because of my cheap class 2 samsung sd card.
whenever the screen turns off w/ openvpn running on the background, the card unmounts itself.
Buy class 4 card. it will resolve your issues. It s hard to find class 6 cards in chennai.

Class 4 SD should do, but it's the minimum. If you have the chance of buying class6, it is worth it. Where i live it costs from $20, good price for an 8Gb class 6 SD. It is a lot faster than class 4 and that shows when running apps from sd.
That should solve your reboot problem too, not only the unmount. The reboot is tied to the SD unmount, as the system has files on that sd partition that fails (ext2/3/4). It will reboot when it needs to access data on the SD.
I guess you'll find pretty cheap class6's on craiglist or ebay.
Take note that ext4 filesystem runs crappy on sd's below class4, so if you cannot get that or above, at least try working with ext2 partitions. Never ext3, cause it is the less stable one. (ext2 - fastest, most stable, ext3 - slower, unstable but has advanced logging, and ext4 - an upgrade to ext3)
I bought 16 gb class 4 for 1500 bux
GPRS reboot
Guys, it looks like some phones tend to reboot while on laggy 2G network. My friend told about his Samsung smartphone getting stuck on UA-UMC network (255-01). I am experiencing problems with my Samsung Galaxy Tab on UA-life (255-07). It happens just after a few-minutes call or on resume from suspend - traffic indicator shows outgoing packets and no incoming traffic, sometimes i get an error about system process no responding or stuck wallpaper animation or other parts of the UI stuck. I suppose this happens because of some special configuration of 2G network when it just stops sending any traffic to the mobile and at the same time some process on the mobile waits for the reply from the internet "hanging", then Android OS detects this process not responding and decides to kill it. Sometimes it causes reboot.
It's just not good that laggy mobile network configuration/equipment causes smartphone hangs/reboots.

Hey all,
I thought I would share my findings to help others with the same issue.
Two days ago I kept catching glimpses of a card image in the notifications at the top of the screen, but it would only be for a second so I could not see what it was trying to tell me. But had a quick look and sd card seemed fine and all data was present on handset. A couple of hours later it popped up with "SD Card Unexpectedly Removed". I tried ejecting and reinserting,restarting device and turning off and removing battery all to no avail. So I did a quick search which showed this seemed to be quite a common issue, after reading many threads with people saying the sd card is corrupt or network providers saying it was software and to do a restore. I decided before all that hassle I would open the phone and check the circuitboard expecting it to be a dry solder joint. One thing I will point out that was different to some other users is the fact my sd card was not visible with the phone connected to the computer, so this may not solve all related issues.
THE FIX
Turn off phone, remove the battery, SIM card and sd card. Remove all screws except the one by the 3.5mm jack. Gently pull the white plastic trim that surrounds the card holders and battery but the top part with speaker and camera does not need removing. Once removed if you look to the left of the sd card holder you will see the ribbon that connects the sd card to the main circuit board and at the end of the ribbon is the connector. Mine was disconnected and was loose, even if yours is not loose it would be worth gently pulling it off and reconnecting it. Then reassemble in the reverse order.
This was a nice surprise in the sense it was a very simple fix. However when I mounted the sd card even directly in my pc it was not found, I assume that the loose connector floating about had probably shorted its connections and caused an issue with the sd card. After a handfuls of attempts at mounting it in my pc it was finally detected and I backed up all the data and reformatted the sd card, then copied the data back,mounted it in my phone and was happy to find it all working as expected.
I hope this information will help some of you out, as it was a simple fix to a simple issue and results from searching had no solutions, just lots of assumptions.
And what can I do
Hi
I read your articles and seem very good but u have a question.
I had the same issue and I saw that every time my phone said I hat message it creates in my sd card a folder named lost. I and then i saw that one part of my battery was going there, ti reconnect the phone with my sd card
I formatted my sd card and did all the things that I found in the Internetbut nnothing works and I just change my sd for another one I had and sincethere u ddon't have any other issue, but my computer detects very good my first sd card and I'm not sure how to fix it.
Any idea?
Regards
Recently ive just faced this issue, what I did is to insert my 32gb sd card in my PC and run CHKDISK, havent got any error while performing this, thereafter i inserted it in my phone & goodness till now this sd card error hasn't appear yet. (finger crossed).
Mine did something like this a few times and then the 32GB Sandisk class 10 card died. Couldn't get it to work in any device except Linux based Media player. Luckily managed to copy my nadroid backup and TB backup. Sent to Sandisk and they replaced it. There is already a thread about S3 damaging teh SD cards. May be the loose connection is what's causing the card to to end up dead.

Yeah,as mentioned I have seen a lot of issues about sd cards, this is the first issue I have had and thought it would be worth mentioning. There is little space when the case is together so it could easily still make contact and seem fine even if the connector has worked loose and cause all kinds of issues. As mentioned mine had the sd icon popping up every now and then before it actually failed. Some users seem to be going through a lot of sd cards with them failing on a regular bassis.
I've been using my 32gb card since my last phone which was the LG Optimus 3D it is a scandisk class 10 one. Anyway i took it out of the 3D and stuck it into my S3 i still have not had a problem. I did take it out a few times to put a rom in because i wiped my phone and didn't have a rom in the Sd card. Also i dropped my phone and replaced the whole front silver bumper bit the whole digitizer because i dropped my phone while playing basketball. It still works. It has been a year now it has been in two phones and still works great. I must be lucky..
I got mugged for the SD though i bought it last year for £60 from Argos a store in the UK. Now you can get them for half the price oh well.. I am waiting for the 128gb ones to come out so going to buy one lol..
today also my Sandisk Ultra HC I 32GB it's died, tomorrow I'll test with pc but no sign of life :crying: WTF samsung !!!
hey i have the same issue with an 32gb sd card, it was workking great and then i was getting the error about
"SD Card Unexpectedly Removed" and then i tried everything i could and my computer detect the sd card and it seems to be working normal but in my phone i have the error over and over again and it was draining my battery too, and the only thing i did was change to another 16gb sd card and this one is working.
maybe there is a problem with the 32gb sd cards
I have a 16GB Sandisk UHS-1 card and i have been getting this issue as well, and its becoming more and more frequent. Whenver it happens, the ringtones/notifications for certain apps like Gmail and Message get reset as the ringtones i set were stored in the sdcard. Also the photo frame app i have on my homescreen often resets to nothing as the pictures were also stored in the sdcard. Its really annoying because I can leave my phone sleeping, only to wake it up realizing my ringtones are all set to silent and my photo frame has been reset. At least i know its a common problem. damn you samsung!
Has anyone actually tried checking the connection on the ribbon as suggested? Mine has been fine since and works fine.

There is no way anyone would know you have opened it, the screws are all Philips instead of t6. As long as you use the correct screwdriver it won't damage the heads and will leave no sign of entery and it takes around 10 mins to complete. Or you could take it to Samsung to do but seems a lot of hassle for such a simple fix.
Also most people are rooted without concern of the warranty.
So there's no seals or stickers that are broken?

Nope, no sticker or seals and just so you know all screws to remove the back are identical, there are only two screws inside which are different but do not need removing for this. You only need a Philips screwdriver ( I used a ph00 x 40) as long as the screwdriver fits the screw well it will not damage the head. Once screws are out a flat head screwdriver or similar are helpfull to prise the back off.
Hi Guys,
A little feedback from my experience with this.
I too was experiencing the "Unexpectedly Removed" error on my 32GB Class10 Sandisk.
It was playing havok with my setup because I use a 8GB Ext4 Partition on the card, where I move 90% of my apps. (About 6GB of that is used by games + their "external" data), and it keeps my phone and FAT32 partition free for important stuff. (I use Link2SD and DirectoryBind)
The problem is, after the device wakes, Link2SD can't find any of the apps, so I can't start any of them, and I have to do a full reboot to get them back. :/
So, after searching and searching, I couldnt find a valid solution.
I tried with a 16GB class10 Samsung, and a 32GB Class10 Samsung card. Exact same setup. NO ISSUES.
Everything works perfectly.
Then I found this thread:
http://forum.xda-developers.com/showthread.php?t=1933743&page=2
Where most of them are experiencing this error with Sandisk cards.
Apparently, it's a known issue with Sandisk Cards (especially the 32GB models), and cards sold after December 2012 no longer experience this.
I have contacted Amazon.co.uk about replacing the card as it's only 2 months old, still waiting for their answer. Will update if anyones interested.
cheers

A curious question if I may.
Was this a SanDisk Ultra (UHS) card? Most (if not all) Android phones do not have a proper UHS-I driver today and, although the card is supposed to switch down automatically, that transition time can fool the OS sometimes.

I read something about UHS compatibility, so I got an SD-HC
http://www.amazon.co.uk/gp/aw/d/B007JTKLEK/ref=mp_s_a_1?qid=1357264092&sr=8-7&pi=SL75
Is it the same thing?
Hmmm. Ok, might be getting somewhere.
Any idea if these cards have an internal "power saving" system that maybe kicks in if voltage drops below a certain level?

Yes, the red and Grey SanDisk cards are UHS.
Yes, they definitely have controllers and the host device can command them (if it knows how). I know that they allow In System Programming (ISP) for updating firmware. They support auto-standby, power-off and sleep modes but am not certain if the card would switch without command. Check the SD link in my signature if you really need more info.

I tested my SanDisk 64GB Ultra card in a Note 2 and it had the same symptoms (Mine were worse, with the card locking up while playing music after a few minutes, causing mmc timeout errors in the kernel).
I switched to a Samsung 64GB Pro card and since then I haven't had any issue. It's also twice as fast.
The amount of headaches this SanDisk card gave me is insane, probably the last time I buy a card from them.
i have sandisk ultra class 10 32gb. try this setup. use minitool to reformat your card then set it the cluster size to 16kb.
for me so far so good. will test this in a couple of days.
Hi ,
My External SD card on galaxy s3 i9300 international version .... shows up on the notifation bar that Sd card removed unexpectedly.... this happens evry 10 mins or 15 mins....
Help appriciated
Have got the exact same issue and drains the battery quicker as it has to keep on rescanning the SD card...I have reformatted the card and it still doesn't help...did not have this issue until last week and don't know what happened for the SD card to keep on being removed every 10-15mins..I have realized that every time I wake the phone up I see the card icon in the status bar for a second.. Sadly I have read that this is a common issue and it eventually can fry the card and make it useless so I have decided to remove it and not use a SD card(main reason I got the phone was for this reason)...since then my battery has been amazing as the media scanner is not constantly running..so far no one seems to have a reason why this suddenly happens as I have not had an issue since I got the s3 which was over 6 months ago and out of nowhere this issue occured..I hope that this may be an software issue which can be fixed in the future or hopefully someone in xda can either find out whats the issue or find a fix till then I will keep my 32 GB sandisk card safe.

Do you use a Sandisk 32GB card by any chance?
I had these same issues, which went away once I changed to samsung cards.
If you can, return the card for replacement, as cards made after december 2012 dont have this issue anymore.
cheers
Interesting, i have exactly the same issue since january 1th. It worked for about a month without any problems (bought it late november).
Now this is killing me how it behaves every 5min. I have reset the phone, updated the phone, formatted the sd-card.. nothing helps.
So if i return my sandisk 32gb, should i ask for a new sandisk or go with the samsung?

Had the same issue with my S3.
Turned out that the SD card was dying, this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the media scanning process.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card, and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:

I've seen my 64Gb Sandisk card auto unmount and remount itself a couple of times today, have seen it once before. Again was caining the battery on the phone with the media process rescanning it.
Thanks for the app I've installed it to monitor this from now on, to see if its potentially a faulty card.

This app is really great, proves the issue. Like others, I have this problem with a Sandisk Ultra 32gb. I tried popping in an old 4gb card (forget the manufacturer) and had no issues.
Saw somebody else suggesting that the Franco kernel fixed this issue, and sure enough it seemed to have cured it for me for a few weeks, but it's just started again today - your app showed unmounts/ejects happening every couple of minutes, so I've now submitted a request to Sandisk to return the card.
Hey all. Over the past week or so, I've been experiencing a problem where randomly, a message will come up in a random task saying something like "SD Card unmounted unexpectedly, it may be damaged." Anybody else experiencing this? It is the stock SD card and I've made 100% sure it wasn't loose or anything. Think this could just be a bad SD card?

I'm running into the same problem. I've been ignoring it in hopes that it's a software issue that will get resolved whenever a JB ROM is released. Are you running a custom rom? I'm running The Base 0.7.3.
Fyi, I haven't had this problem at all in over two months of use. Ran stock for about a month and The Base rom for the past month.
Thank god other people have had it happen too. It's happened to me a lot BUT.. I had a 32gb class 4 SanDisk in my phone and that was constantly unmounting itself but I put the 16gb that came with my phone and it has yet to do it. Are you guys using a card other than what it came with?
Sent from my LG-E970
It happens to mine quite a bit, probably 7-10 times a day. I'm using a SanDisk 64GB class 10 SD card, formatted as ExFAT. Maybe I'll try switching back to the stock card to see if that has anything to do with it.
I had the same problem and switch out the card and the error stopped. I had the 32GB SanDisk Ultra and with that card it I was getting the random dismounts. I replaced it with the stock card and was working fine. I returned the SanDisk card and got a new one and it seems to be fine for about 5 days now.
What file formats are you using. My 64 GB is formatted as Fat32 and I've never had this issue. I also think that the included SD Card was pre-formatted to Fat32 which may be the reason it stopped when you switched back to it.
There you go... I've always used the stock sd card. Are you guys losing data when this happens?
This used to happen to me on my 64GB Sandisk Class 10 formatted with exFAT. I fixed it by running CHKDSK with both options checked in Windows 7. Hasn't happened since. It said it didn't detect any errors but it did something lol.
I don't believe I've lost any data. All of the songs I put on the SD card still play. I may try repairing it or using the SD card from my inspire, which may prove to be worse since I think it's only a class 4. I'll post once I figure something out.
One last thing was I tried doing a non-quick format of the card and after that my phone would not recognize that card at all until i exchanged it for a new one.
I generally don't recommend letting Windows GUI format a flash card. Google around for windows make clean, windows command line clean and format. That's your ticket right there.
Hi,
Over the last week, I've had two SD cards die on me:
The first card I've had since I got my i9300 S3 (13 months). Prior to last week, it worked flawlessly (KomputerBay 32GB class 6). Then suddenly after rebooting I see an SD card damaged error. After trying chkdsk and fsck it looks like the card is certainly damaged but was able to recover some of the files.
Thinking it was just bad luck and the card dying, I purchased a 32gb class 10 Lexar card brand new. In the meantime, I used a 4GB Samsung SD card that came with the S3 for approximately 5 days and it worked fine with no errors or corruption.
With the new card, I copied over all my files, music etc. After an overnight using the phone, some calling etc. I rebooted the phone only to get the same error. Windows didn't even recognise the card let alone recover it. fsck likewise. Did a full format again and restored some files from original backup, it's been less than 24 hours and so far so good but I am not ready to relax just yet.
I'm really baffled as to what could be causing it as the card seems only to fail after a reboot. Prior to then, the card displays as mounted in system settings and files are accessible. The only other strange thing I've noticed is that when playing music/podcasts and turning off the screen the playback jitters for a moment or two before returning to normal. This started quite recently. I'm using UltimaROM 13.0 at the moment with Boeffla kernel. Have disabled all SD related optimisations and have no CPU or GPU overclocking or undervolting. I've been using Ultima for months with no major config changes recently.
I'm at the point now where I am almost scared to reboot! Last time I rebooted I unmounted the SD just in case. The only other possible difference in behaviour is that as I was travelling I had my phone on charge all night and although I can't be 100% sure rebooted with the phone charging (though again, its not the first time I've rebooted while charging). I've googled this far and wide and most SD related issues seem to be caused by the card randomly unmounting. I've never seen this in my instance.
Any ideas on what this might be or what I could do to troubleshoot further? I don't want to restore to stock, unroot, reset counters etc. and return to Samsung unless I can be at least reasonably confident its a hardware issue.
Thanks,

Do you mean http://forum.xda-developers.com/showthread.php?t=1906058 ? If so, yes though the key difference for me is that my card doesn't seem to randomly unmount like most reports indicate. Also, it's very recent. Don't also see any possible solutions in there unless I'm missing something?
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: EVO Select 128GB MicroSDXC UHS-I U3 100MB/s Full HD & 4K UHD Memory Card with Adapter (MB-ME128HA)
The typical SD problems Samsung is known for. Asking Samsung for solutions is not very informative. Please any suggestions would be great.
If not I guess I just ditch Samsung A52 5G and go back to the other evil the iPhone. Heck at least every time you turn that on it always works.
This sure seems like a great phone but that SD card issue is really a big deal at least for me.
HAve you tried the same SD cards on other phones or a different SD card on the same phone?
Yes, I actually bought 2 exact same cards, no issues anywhere I use them except in the new Samsung A52 5G.
Reading a lot of other posts seems to be a pretty big issue with Samsung and Android 11.

What about if you borrow a card from a different brand? I swtiched the old SD card i was using onto my A52 5G and never had any issues. Could it be a problem with samsung cards? For reference I use a Kingston 32GB MicroSDHC with UHS 1
Try formatting card in phone if that doesn't get it try doing a low level format on the PC with a 3rd party app do not use the Windows formatting utility.
Then format again in phone.
Load card through phone.
Formatting the SD card was the first thing I did using a Linux PC. (Manjaro OS ) This was always my goto if I have formatting problems. The SD card was done in exFAT, however no luck.
The other option is buy a different brand SD card as mentioned above by "ImGonnaTryScience". (Thanks)
The card I'm looking at is the
SanDisk 128GB Extreme MicroSDXC U3, V30, 4K, A2, Micro SD.
I'm thinking maybe the Samsung SD cards are to slow, but who knows.
What doesn't make sense is the Samsung SD cards work everywhere with no issues.
I even have an old Galaxy Tab 7, Samsung SD cards works great in that. Speaking of my old Tab 7 I tried formatting the SD cards with that and then put them back into the A52 5G. This didn't work either. My thinking was Samsung should like Samsung but my thinking was wrong. (Maybe I should stop thinking.)
Speed in SD cards matter sometimes (for example the SD card I use in my dashcam needs to be a certain minimum speed otherwise it won't be able to record properly), but I find it very odd that it wouldn't work for a phone.

Not giving up just yet, I really like the A52 5G.
V30 should be fairly fast from internal memory to SD card less using the C port.
If you did a low level format then put it in the phone with not data on it, then formatted in the phone again... it should work.
I've had issues like this on my S4, now you see it, now you don't. I had to do a low level format to make it readable even on Windows. May have been a bad card but all sectors were intact.
May be card brand. Even afterward it would not see the requiring a reboot.
I'm using the Lexar .5tb V30 card in my Note 10+ and unlike what happened on the S4 the 10+ recognized immediately. Formatted it in the phone and zero issues since.
OP I feel you. This is a frustrating issue that really jams a monkey wrench in the cogs.
I be seeing red.
Pedal to metal, no brains diagnostic solution; get the Lexar card if the size and speed rating fit your needs.
$64 and known to work out of the box.

Well I may have solved my problem. I completely wiped the SD Card using MiniTool Partition Wizard. However I didn't add a partition or any kind of formatting. Once the card and partition was completely wiped I put it back into the A52 5G and let it do its own partitioning and formatting of the SD Card. Everything is working really well no more SD card errors, just hope it holds. ( 12hrs and still working, before that the error would pop every 30 minutes or so.) ( Still using my original SAMSUNG: EVO Select 128GB SD Card)
I'll update the progress in a few days.
Some reason the wipe of the partition seemed to do the trick. I don't really understand why since like I said the card worked well in everything except the A52. Maybe Samsung changed the format structure compared to there previous tablets and phones. Maybe its even an issue with Android 11 . All formatting in the past was always exFAT however something changed with this phone. I hope this will help out others who may be experiencing the same problem.

It's possible there was some app on it with a secure partition or something.
It may take or do what one card* did in my S4+, while never lost data it would go through spells of not being recognized by the phone requiring a reboot. No rhythm or reason to it.
Having to low level format a new card is not a good sign.
Next card get a Lexar, slam it in, format, good to go.
* it wasn't recognized by the phone or Windows. Only the Lexar formatting app could access it. After a low level format it was visible to the phone and Windows.
Really?
Well I said I would let everyone know the progress. Simple terms FAIL.
6:00AM this morning the error came back. ( SD Card was removed unsafely )
So I guess now I'll try the new SD card I mentioned above or the one mentioned above by Blackhawk ( Thanks for the info. )

Well .5 tb will be nice to have.
I hope this works...
Format in phone.
I would leave the card in the phone and up/download data via the phone rather than removing the card to do so.

Found another interesting read. Maybe Android 11 is the issue.
Reading through this post I see the Scandisk Extreme SD card has issues to.
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...

I have no love for 11 and running on Pie quit happily on my Note 10+.
Can't say that Lexar card is know good for your phone because it uses a faster and different memory controller as well as the imfamous A-11 OS.
However before blaming the hardware or firmware I would give the Lexar a shot. It's a nice card to have regardless.
Well I picked up the sd card member Blackhawk was talking about this morning. A Lexar High-Performance 633x 512GB MicroSDXC UHS-I Card. I put the card in fresh out of the package let the A52 format the card about 4 hours later same as before, the fault came back. After reading the post the Blackhawk wrote about his pie made me think I'll try that. Fired up my pie4 and let the pie4 do the format. Well no luck there either within 30 minutes the fault came back. Well now I know its either the A52 or its Android 11. The cards both work really well in all may other devices. However the A52 5G is the only thing running Android 11. Now the question is return the phone or wait for Android 12.

Sorry to hear that. I meant that Pie as in Android 9. Try the Lexar low level formatting utility if you can find it. Again, format in phone before you use it to be on the safe side.
It seems it's the phone.
Try clearing the system cache.
Doubt check setting and clear data in associated apks. It still may be something not so obviously obvious... Androids wuv being played with.
Well I finally got the respond for Samsung I was looking for. It's not the SD card but an issue with there firmware. They claim it will be addressed with the next update. I used the Samsung Members App to send them an error report from my device and the response was quite pleasing.
( See there response)
Congratulations, you're a remote Samsung beta tester!
Just sloppy and unprofessional on Samsung's part and no fix... yet.
Eventually they'll get it but it should have never made it out for retail sale like that
Personally I'd consider asking for a full refund as without a working SD card slot the phone becomes a liability for me... as if this little ride hasn't already. That used 10+ is looking more tempting to me.
Wow. Well done
Hi another issue with SD. When I have tried to make a backup on the an SD card via the setting app it stuck after 85% and the result of it I got an SD with "write protection" which I can't change not via DOS not with other 3rd party tools. by the way its working on Samsung tablet including format and copy files but when I put is back to my mobile or try to check it on PC to delete the portion or make any change it still same issue "write protection". Would appreciate any idea before I put it to garbage. Thanks
