[Q] External SD Card Encryption and Overheating - Verizon Samsung Galaxy S 4

Hello
Wondering if anyone else has had this experience.
I'm on the Stock Verizon 5.0.1 rom. I encrypted my SD card. I chose to not encrypt media files.
Afterwards, the phone began overheating frequently, I couldn't figure out what App was causing it. Then I remembered that I just encrypted the SD card. So I deactivated the encryption and now the phone is fine.
Anyone else have the same experience?
I use a Sandisk Ultra 128gb card.
Thanks

Sch-I545 model support until 64GB of memory card as far as I know, if you have 128 GB, that could be the reason...

I'm not encrypted running same ver. 5.0 with 32g sd and getting the overheating from SD . If I remove it, no overheating. Any ideas what could be causing this?

The 128gb card works fine. But maybe a different card will work better. I assume that the overheating is associated with the encryption overhead, but I don't know.
I'm not having the issue without the encryption. deaves7, maybe you have a bad SD card? Have you tried another?

Update.
I backed up all my SD Card data, reformatted the card from within the Galaxy S4, and then enabled encryption.
So far no overheating, but the amount of data on the card is a lot less because I haven't copied all my files back.

Reboot issue with Apps installed on SD Card?

I posted this issue on Android Central as well, but not as much chatter over there. Here is my issue:
I had this problem with my Samsung GSII as well and thought it may just be a fluke, but now I am having the same issue with my new Note.
Due to lack of free application storage, I move (VIA the App manager) most of my larger games on to the Micro SD card. Which looks like it works fine, however, after a while, not so much.
The Note (and all Samsungs) go through the scans when you boot up the phone on the internal storage and the memory card... Upon completion of this scan, the phone just keeps resetting. Once I pull the memory card out, I am good to go, but all my games were on the memory card.
I am using a PNY Class 10 card and am thinking maybe it is corrupt? Or maybe I am really not supposed to load everything on to the card like that?
Thoughts? Anyone else run in to this?
Thanks!
you do realize that most apps including large games take less than 50mb of space. and we have a 2GB storage partition you can store hundreds of apps with no problem. TBH i wouldnt bother with moving them until you do actually run out of app space.
As much as I hate to admit my app problem... I have long ago surpassed the 2G app storage..
After years of purchasing apps and many very good free apps of the day from Amazon, 2GB no longer cuts it for me.
Thanks.
wow really well the issue is that the phone itself uses the internal memory as the default storage location. There are some hacks but i wouldn't recommend using them on this phone as they are untested. Do you honestly use all those applications? I have tons of apps that I really dont use anymore that were from the donut days of android.
Your response sounds like some of the responses I get from our developers... "Well, tell them not to use it and it wont break!".
I say that in good fun. No, I dont use them all, but whenever I get a new device, I like to load it up with my stuff to test it out.
I could definitely remove or just not install about half of them, but again, that doesnt fix the problem. It simply avoids the problem.
Thanks again for your response.

I have the same problem & no solution. I ended up restoring the Note on day 3 of ownership due to the constant resetting. Is there a way to make the internal 16GB the default install location?

Honestly, I have about 8 gigs of apps installed, all moved to external SD card - a 64GB Sandisk Class 6. No reboots and no issues at all. Always move everything I can to external SD. Not sure why, just some mental preference in me likes to keep the phone itself as free as possible. Never had a restart or a crash because of it. Always used App2SD Pro app or Force to SD if rooted andnits been flawless - same experience on the SGS2 as well. Sounds like a corrupt card to me, honestly. Were you using he same card when you had issues in your previous Samsung devices?

External SD card help

I have a Sandisk Ultra class 10 64gb external SD card which has worked well since I purchased the phone (several months ago). Recently however, I've been running into issues where the ROMs I've tried won't recognize it (Beans, Carbon, Liquid). The strange part is that TWRP recognizes it without a problem (I've flashed from it several times). I've tried both nandroid and clean flashes. I've done a a battery pull and booted the phone without the card mounted. When I insert the card, I get the typical "Preparing SD card" message, which doesn't seem to go away.
Anyone have any suggestions on how I could try and fix it (other than hopefully buying a new card)? Thanks.
EDIT: Ignore. Formatted the card and that seems to have fixed it for now.

I was going to say, Format the card should do the trick.
I have the same card but the 32gb. On Amazon alot of people complained about the card not functioning after 6 months of use. So I opted for the 32gb version which had the same complaint, just not as abundant.

I see you've fixed the issue, just in case you didn't already know though AOSP ROMs can only use the card when its formatted as fat32. TW ROMs can use the card formatted as exfat. Going back and forth between TW and AOSP may have corrupted your card if it wasn't formatted as fat32 when you went to AOSP.

It had previously been formatted as Fat32. Guess we'll have to see if it stays working or if the card died. Thanks.

It may just be that the card died, I have several 64 GB class 10 micros and have no issues, from what I hear though the class 10 is the worst and if you can get the original 64GB that wasn't a class 10 these issues aren't there.

I'm guessing something got corrupt somehow, or the card is on its way out. Once I reformatted it, it started to work again.

SD card overheating question.

I have a question about the SD card overheating issue. Are people having the same problem with the faster class 10 SD cards, or is it just the class 4 cards. I have a Sandisk16gb class 4 card, and I am experiencing overheating issues. Thoughts? Should I try upgrading to a card with a faster transfer rate? Running stock OC1 unrooted. Any input would be very helpful.

Your SD card is overheating? How do you know this? Do you mean your phone is overheating?

It's a known issue, that the phone will overheat, specifically where the SD card is located. So I suppose, yes the phone is overheating. I have never heard of anyone else asking the same question as I have. It is a common problem on the last 2 or 3 stock I545 OTA roms. If not I suppose I've spent days and days and days of dead end research, trying to figure this out (this is only a fraction of the problems this phone has). All I wanted to know is if someone has had different results with a better class SD card, or if it's just the lower class cards this seems to be a problem. I have tried different class 4 cards all the same result. It doesn't seem to overheat in that area when the card is removed.

I'm pretty sure the area of the SD card is getting warm because the CPU is located there as well. I don't think its possible for an SD card to overheat. I would look into apps that may be overloading your device and heating it up.

SD card mounting and un mounting on continuous loop

Hello all,
I'm stuck with an issue where my sd Card is mounting and unmounting on a continuous loop. Just upgraded to marshmallow.
I thought my Sd card has Just gone bad, so I purchased a new one. This new card is doing the same. I'm thinking maybe amplify or greenify is shutting down a service for the sd Card. Does anyone know of a solution?

My wife has the same problem with her G3. It started on 35b when she tried to move an app to the external sd card. The problem persisted even pin 10b and now 46a. Tried several sd cards with no luck.
Is there no fix for this? I have a 128GB micro SD card just waiting to be used on my G3.
I've tried multiple cards, reformatted it with the "quick format" unchecked in Windows, and rolled back to Kit Kat. Only thing left to do is replace the slot, which looks time consuming and requires soldering skills. I don't have the latter.
I thought I had a fix. Reformatted the card and it stopped unmounting... It was good for about 5 minutes!
My fiance has a 2nd LG G3 that Just started doing this as well. I'm thinking it is the Rom causing it.

Micro SD card gets corrupted occasionally

The 64Gb Strontium Micro SD card in my Redmi Note 4x (MIDO) works good, but then becomes corrupt occasionally, (about every 6 weeks).
MIUI says the card is unreadable and needs formatting.
If I take the card out and put it in a computer it can no longer read it either.
If I use DiskGenius, (data recovery software), I can recover the data and save to a computer. I then have to repeat the process of putting the card back in the phone and reformatting it (fat32) then load the recovered data back on at it works again for a while.
Has anybody else encountered this? Do you think it is the card or the phone at fault?
Reformat your system.
What backup tool are you using and your back up timings?
Seems card is being used aggressively?
At same time between multilevel applicatons..
Are you storing and running high configuration apps or games while same time backup etc. Is on?
Hi IODroids, thanks for your reply.
I only use the card to store music and Titanium backups, no apps or heavy usage.
I always format using the phone.
I guess I will know if it is the card or not in a months time.

I was facing that issue long time ago when I used a cheap micro SD. Especially when I worked with multiple or big files (for example with Titanium Backup)
Then I bought another micro SD, a little more expensive and problem solved
OK. I have replaced the micro SD card and can confirm that the replacement has been rock solid with no issues over the last few months.
Just saying this in case someone else has this issue and stumbles across this thread.
