I have been the owner of this Samsung Galaxy S9 for about 13 months now, and earlier today my battery died. When I turned the phone back on after partial charging, it acted extremely strangely. It rebooted to the secure boot pin screen a few times, and even to recovery mode a couple of times, rebooting about every 3 minutes. But that isn't it; wifi and cellular refused to connect, the screen would not go off if I pressed the power button, the settings app would not open, many other apps barely works, and the device was very slow for the time it was on.
I did the usual troubleshooting steps, clearing the cache in recovery mode, booting into safe mode, uninstalling recently installed apps, scanning with Knox and Malwarebytes, nothing. But, I remembered the day before, inside Samsung Gallery, there was a little text box before my images that said "SD Card has corrupted information, please back up your SD card and consider replacing it." I didn't think too much about it, or screenshot it. Well, to try something, I removed the SD card and booted normally. The only thing I changed that time was the lack of the SD card and voila, it worked fine. Haven't had an issue since, and I honestly think it might be running better.
For my amateur speculation/hypothesis: I believe when Android starts up, it tries to index installed SD cards. The card I am using is an old Samsung Evo 32 GB card, to the tune of 5+ years. Possibly, with the age of the card, there was light corruption in one folder or cell, and Android didn't know what to do with it. I can't find any corrupted files, but I guess Android hung on parsing the microSD card. I just wanted to share my experience and see if anyone had heard of something similar; I sure cannot find anything on it.
TL;DR: A corrupted microSD card in my Galaxy S9 caused Android to lose most function, and bootloop. Usual troubleshooting did nothing, however, removing the card returned the OS back to normal.

I am using Cyanogen 5.0.6 on my N1. I flashed it about 5 days ago.
Backstory: So I was connected to my car stereo via bluetooth on my way to work this morning when the songs stops playing. I then pressed the skip button on my receiver but nothing happened. I then looked at my phone and realized that it was off. I tried pressing the power button to turn it back on but that did not work. Then I removed the battery and then replaced it and pressed the power button. It turned on. The main problem became evident when I got to the home screen and it said "Blank SD card - SD card blank of has unsupported filesystem."
Is there a way to recover the data that was on this sd card? It is asking me to format the card, but I would rather recover the files if possible before formating. Also, is this a glitch with Cyanogen, the 5.0.6 ROM, Android 2.1 or something else?
If anyone could help me, I would greatly appreciate it.
No idea what could have caused it but as for recovering files just try one of the many programs out there.
Ive persoanlly had success wity a program called recova for windows
Thanks Phantom.
I had a spare memory card at home. It was full of videos so I had to format the card. Once it was formatted, I stuck it in the phone and rebooted. Everything was fine for about a half hour. I then loaded up some of my files that I wanted on the card, mainly just photos and documents. Then I thought I would go back to Cyanogen 5.0.5.3 so I loaded up the zip file on the root of the card and turned the phone off. When I went into bootloader it wouldn't recognize the card. So I was forced to restart the phone. Once it got to the home screen, a notification popped up saying that the SD card is damaged. [naturally there were expletives]. So now I have two SD cards that I cannot use on my phone. When I put the cards into a USB adapter, the computer only sees a few MB of the SD card and does not allow me to format.
I have now just about reached the limit of my computer knowledge.
The two main questions are:
1. What caused this?
2. How can I fix it?
Please keep in mind that I am a noob when it comes to most of this stuff so I would appreciate the help to be kept in layman's terms as much as possible.
Thank you!
my stock nexus one becomes highly unstable after booting up. im running strock 2.2.1, and this issue started apearing recently (after 2.2.1 update). the phone has never had any problems in the past.
whenever i turn the phone on, if i touch it it becomes really laggy and freezes, requiring me to pull the battery. however, if i let it sit for 15-20 minutes and then play with it it works fine, until the next time i shut id down (which can be days). i have performed a factory reset without reinstalling all of my old applications, i have formatted my sd card, and i have checked all the applications that start on boot up, but none of them seam to be the issue (when there was nothing on the phone it still reacted this way)
any suggestions? should i contact htc? this is really annoying.
Before you do, you could try to root and check the logs for anything suspicious (logcat and kmesg). Also you could try to install custom ROM and see if the problem still exists.
If it doesn't help - you should contact HTC.

Factory reset with formatted card? Has to be something wrong with the phone.
Go to recovery, wipe cache and dalvik cache, and try to boot phone again, often that helps.
tried wiping everything i can through recovery, yet my phone still freezes soon after start up. any chance htc will fix this? i dont want a refurb
Because when system has just booted up, it needs to check SD card and mounts all App2SD applications.
Try to boot your phone without SD and SIM card, see if it solves the issue.
tried removing sim and microsd and all th possible combinations.
it runs great without the microsd, so im guessing that was the issue. ill try another microsd to make sure its not a hardware/software bug related to sds in general but rather an issue with my specific microsd (which isnt the stock one).
thanks for the suggestion. i was very close to sending my phone in to htc (already had a ticket open and a fedex label)
that sounds good perhaps your SD card was corrupted. Connect it to your computer using a card reader, and do a disk check in Windows, see if it can fix any problem. Also try to degragment your SD card.
First off: Motorola Droid running CM 6.1
So I've searched around, and everything I've found seems to be missing an aspect of what's happening with me, so I figured I'd just go ahead and start a thread and ask.
Basically, my SD card has been working on and off. It started one day when I turned off my phone and then turned it on later. The SD card was in and I could access it via Root Explorer, where I could see everything, but none of the apps were working at all. Restarting phone did nothing. I turned it off, pulled out the battery and pulled the SD card out, blew it out a little, put it back in, turned it back on, and it seemed to work as normal. I wondered if my problem was gone, so I restarted again, and same problem, no apps. I finally got it back on with the apps on the SD card working, but now, I can't mount it on my computer via USB. When I plug it in, it says drivers were installed and device is ready to use, and it starts charging, but there is no notification on the phone to mount the SD card. On top of that, I can't seem to install anything or update anything through the market, and I'm not entirely sure all of my apps that are on my SD card are there, but I can't be positive, because all of the ones I most use are. I'm sure that if I restart my phone, the same thing will happen again, so at the moment, I'm fine that my apps are working, but there are times when I need to mount my SD card to transfer files and such. Like I mentioned, I did search, and the closest thing I found was USB Brick which seems to be solely focused on the HTC Desire, but still seems to miss some aspects of this, mainly, no one mentioning that they could access their SD card while the apps weren't working. This makes me think it may be some sort of problem with the system or perhaps something wrong with android_secure or Android on my SD card. (Maybe an app on there messing something up?)
Any help would be appreciated. If this is a dupe thread, I'm sorry. If you could point me where I need to go, I'll go there and this thread can be deleted or closed.
So where do I start?
I rebooted my droid bionic, UNROOTED, pretty much stock.
When it booted back up, I noticed that some shortcuts on my home screen weren't working.
When I went to run them from the app draw, they weren't there either.
I seen this same problem on my D2G when I was running a class 10 SD card with apps saved to the SD card. The diffidence here though was that apps were saved to the internal storage vice the SD card.
When I went to manage apps, my hunch was correct. It was only affecting programs which were moved to the internal storage.
When rebooted again. It would affect other programs and sometimes even recognize the programs it failed to on the last boot.
I did a factory (hard) reset and that still didn't fix the issue.
I then brought the phone to Verizon and gave them a demonstration.
They then tried it on their phones in the store and came to the decision that this is something affection all droid bionics.
If anyone else is having this issue please feel free to come forward. There weren't any bug reports on this yet, so make sure you let your local store know to put it in their forums so this can be addressed quickly.

So I took the windows phone plunge and purchased the Lumia 1520 Friday when they became available. Finally had a phone available I wanted with a memory card slot, which was a must have, and top end hardware, which was also pretty important.
I'm running into the same problems that most everyone else who changes from Android has with things being different, and not being available...but nothing major.
I have, however run into 2 pretty big things that may have me turning this phone in before the 30 days I have to do so are up, but I wanted to ask if anyone else is having these problems to determine whether it's just my phone, or a known issue.
I've added a Sandisk 64G SD card to the phone to store data, music, videos and pictures. Turns out it's kinda useless for data because of the lack of a file explorer ap, and the purposeful design to prevent such a thing. Ok...I can cope with that...that's what a USB key is for.
However...what I'm finding is that the pictures/videos/music I am putting on the SD card are being randomly deleted after I put them on the card. I've tried formatting the card using the phone, even going so far as to do a hard reset of the phone and bringing it up with the SD in it, and then formatting it immediately. It still randomly deletes files, mostly photos. I store a few thousand photos of family etc, and some of them are not things I am comfortable storing in skydrive...so that's not really an option. I've tried putting them directly into the folders using Windows Explorer on windows 8, and using Windows Phone Ap for Deskto and syncing through that interface. In both instances, everyting I put on the phone makes it there, and is viewable on the phone...until it randomly disappears. And it's not all of the files, but just most of them...particularly when the phone reboots.
In addition, I've had 3 or 4 times where the phone has randomly shut itself off.
So the question then, is this something that's a known thing with windows phone 8, or is this likely just a bug with the 1520, or perhaps just my phone in particular?

Sounds like an incompatible SD Card issue to me, despite the phone being advertised as being capable to be upgradable to 64GB, some SD Cards may not work and cause major issues like phone rebooting, files being deleted and other annoying issues. You can see if this is the case by simply removing the SD card and barrow a 32GB SD Card and see if you still experience these issues. You can also try leaving the SD Card out completely and see if the phone reboots itself during a test period without the SD Card.
I know this might put you off of continuing to use Windows Phone products (Android had never these SD Card issues on high end phones so long I can remember), but once you go Nokia Black (= firmware update of Nokia for WP8 phones), you'll never turn back, meaning there is more to WP then the eye can see (much smoother and more stable than lagdroid , although I myself find android 4.4 is improving, WP has the same smoothness on midbudget phones than Android high end phones even with cyanogenmod installed).

The only real issue I've had is the storage disappearing. The shutdown thing, and it's a shutdown, not a reboot, is annoying but wont' be a deal breaker.
I have a 32G SD I'll try and see if I have the same data retention issues. If I do, this phone is either going to be replaced with a new one, or I'm getting a note 3, depending on whatever anyone else has to say about this issue.
Thanks for the reply
*edit* - Changed the phone out yesterday. Seems to be holding photos and songs on the SD card, even through reboots. My journey to the dark side may be complete /nod
