Nexus Freezes After Filling up SD card

Everytime I put large files onto my SD card, say a movie or what not, and unmount it from the computer my nexus one starts running extremely slow.
The phone then goes into standby normally and I am then unable to wake it up. I figured it must be updating the files or something as I installed that led cpu usage app, so I left it overnight to do what it had to do.
In the morning I noticed the phone had become very hot and pushing the power button only made the bottom capacitive buttons light up. I resorted to taking out the battery and booting the phone again, the phone is still slow and then it goes back into the dreaded SOD (standby of death).
I tried formatting the sd card but the problems persist, after a while it tells me the sd card is corrupt. The only way to fix it I've found is to wipe the phone and re flash the rom.
This happens on a frequent basis now with the froyo roms, find myself wiping every second day.
Is this problem to do with my SD card? Is anyone else having this problem?
I am running FRF83 and had this problem since the first froyo leak. I have a class 6 8gb card.

Same problem here on FRF91
Some problem here on FRF91.

[Q] External SD card not getting registered from time to time?

When I first got my 2x I had no problems with a dismounting SD card. But recently it has started to happen and generally when the phone reboots on its own and such. When it then comes back online it has dumped the External SD card and I am either forced to peel off the cover and then disconnect and reconnect the card.
Or simply reboot manually and go from there. Either of the 2 methods remounts the card, but I am simply at a loss as to what causes the phone to dump it the first time around.
Anyone got any ideas or tips on this?

Tried with different cards?
I have not experienced this whatsoever. I'm using Transcend 8 GB class 6.

I don't really have a huge choice of cards considering the one I am using is a 16 gig one . And it worked juts fine in the HTC Desire I had before the LG.
And it worked fine in the beginning, with the LG. The phone only started being a bit retarded about it a week or 2 ago >_<

I've had the exact same problem. No idea when/why it happens :<

Same here...

And same here, started a couple of days ago.

I would try to format the card with SD Formatter from Panasonic. Do a Google search. I works real good.

I notice this problem only happens to me if I restart the phone using an app (or via clockwork). I have resigned myself to no longer restarting but to instead, shutdown the phone and manually powering it on again..

Please add your support to the thread over at MoDaCo about Paul's reboot app then...

Same happened to me last night. I've had my Optimus 2X for 5 weeks now, never had any spontaneous reboots, it was quite stable actually. Last night I mounted an 8 GB Kensington external SD for the first time on this phone, with some music and videos on it. After booting up, everything worked perfectly. Then, I went listening to songs via YouTube. All of a sudden, nothing but a very loud humming, which continued after I removed and put back the earphone plug. And then, the phone rebooted by itself, for the first time. After it had rebooted, the external SD was still visible using AndroZip, but it was empty! I was pissed off and went to sleep. Just now, I shut off the phone and started it again, and the external SD is back, with all the stuff I put on it last night. So this incident kind of freaked me out. I mean, the 2X isn't what you call a low-end, cheap phone, is it?

same problem here

Did this happen to anyone on stock rom or could the issue be related to a custom rom?
I have been using a class 6 16GB sdcard (unbranded from a reliable seller @ ebay) for about 2 weeks and did not encounter such error, but I am still on stock rom.

Didnt have it on stock, so it could be a custom rom problem, though i had it on fr17 and cm7 and everything based on that. Seeing as fr 17, if im correct, uses stock as a base it should be possible to happen on stock aswell. Someone correct me if im wrong though

sometimes i also have the mount problem, also in recovery ...
a reboot helps in most cases, sometime it needs 2 ...
i also notified that software reboot to recovery (with an app, o2x reboot) causes mounting problems of sd card more often than rebooting with magic keys ...
but it´s not happening regularly, so i can live with that ...

i had it twice on stock, but in a month's time, so it isn't so frequent fortunately

I have the problem on stock rom and if I do a restart... The phone gets hot where the sd card is once loaded back up. Its shows as Unavailable in SD & Phone Storage and have to then just switch the phone off/on and it shows up again. Strange!.
It must be something to do with a soft reset!....

has anyone figured out a solution to this problem yet?

I was about to start a new thread on this prob,luckily i saw this 1st. I also face this prob. My class4 16gb sd card sometimes become unavailable without any notice. Any solutions?

SD card causing major lag

I'd been experiencing significant lag on my Note 4 since I bought it back in October. It seemed to have been getting worse over the months, until - as a big fan of the Note series - I was embarrassed for other people to see how poor the performance was.
The problem pervaded most functions, including launching apps, scrolling across my home screens, launching the running apps selector, etc. And by lag I mean a pause of up to 5 seconds.
In addition, occasionally the phone would unmount then remount my SanDisk Ultra SD card. I thought this problem was unconnected.
Yesterday after getting to the point where I'd reluctantly decided never to buy another Samsung phone, I tried removing my SD card. Immediately and ever since, my phone has been performing beautifully. Almost no lag at all, for the first time since I bought it.
I can't find this topic on the Note 4 forum, which surprised me. Am I the only one to have encountered this problem? Or maybe I'm the only idiot who would take seven months to realise the SD card might be causing a general performance problem...

I get lags. I didn't realise it could be the sd card. Let give that a try

If the phone was mounting and remounting the sd-card your sd-card might be broken, causing the mediascanner to constantly scan your items in the background causing slowdowns. Have you tried formatting the sd-card on a PC/Mac to exfat? If you still face issues then it could be that either the card itself or microSD slot is broken.

My laziness dictates that I ditch the SD card
To be honest, the lag was the big problem and I can do without the extra SD storage.

Try changing your sd card. I'm using 32gb external sd card and never have experienced any slow down due to its use.

SD Card formatted as internal storage randomly unusable on cm13

I love marshmallow's adoptable storage feature, allowing me to install more apps. This feature worked beautifully for about a month and a half. However, I shut down the device, plugged it in to charge, went to sleep, and the next morning, the apps that were moved to the sd card were not available anymore. They were all greyed out on my launcher(Nova). I moved about 4 gigs worth of mostly games. Fortunately, most of them had cloud storage, but some favorite games didnt. This isn't that big of a problem, but I'd like to try to fix it. So, I went here for help.
At first, I thought the class 10 SanDisk 16gb sd had just gotten bumped out of the slot where the connections happen, so I opened the back cover and removed and inserted the sd card. The notification that prompted me to put the sd back in went away for a few seconds, but then came back. I repeated the process of removing and inserting the sd a few times, but still no moved apps were available. I put the sd into an adapter, then into my laptop, and it showed on file explorer. So the sd card could still be recognized, but maybe unusable.
I dont know what happened, one day it was working, the next day it wasn't. I know i formatted it as internal and portable storage a few times, so maybe that wore it out. I'm running cm13

Hello,
On my phone I used the micro SD card normally as external storage. On day I plugged in my headphones and there was no music. I though that the micro SD card must have come out. However, reinserted it it didn't work. I wouldn't open on computer either. While I don't have a solution, I am pretty sure I also had the same problem.

Once I was taking pictures with my phone when it crashed and rebooted. Some hours before the crash I uninstalled some apps and installed some others (but never rebooted the phone). After the phone started again after the crash, all the pictures and files were gone, the uninstalled apps were there as if I've never uninstalled them and the new installed ones dissapeared.

how long have you used your sd card? i'm sure that the more you use a micro sd card, the more it will wear out and become unuseable/corrupted. That has happened to me before, where the sd card just stopped working.

I have used it for about 1 year. So it may be that but, it has never occurred before.

Same problem here, you can read it here. While I am writing hopefully my files from Titanium Backup are transfered to my laptop. It got worse and worse, in my opinion the sd-card has reached it's end of life because of it's heavy usage. Error occured the first time after the phone got really hot recording gpx tracks. Bye bye sd-card
Another opinion is that warranty is over after two years, so the phone can quit it's duty now - obsolescense plans

yeah, i'm starting to think my micro sd just bailed from wear like that too, but i got to use mine for just over 3 months. i ejected the sd and put it into my computer, and interestingly enough, on my computer it reads 16 megabytes. i was like WAAT that cant be, i formatted it, put it back in my phone as portable, and it read as the normal 14gb. i'm starting to think my sd as internal is the cause of my random reboots. im even running the lastest cm13 update too...
i guess ill try and use my sd as just portable storage from now on, and see if i get any random reboots..

I switched to TurboROM which is using the sd-card as a portable media device, so no more encryption, heavy usage and complete data loss if you do not get your encryption key with root permission.
System space left after complete recovery of my apps with TB is quite nice - but you do not have the possibility to use App2SD (correct me if I am wrong).
So the only way to save internal system space is to move pictures, movies and heavy openstreetmap cards to external.

Corrupted SD Card backhanded Android Firmware

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.
