SD card causing major lag - Galaxy Note 4 General

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.

[Q] Can a problem with Micro SD card cause the phone to slow down or freeze?

I've been having strange problems since going to 2.3.3 (Darky's ROM, but I don't think it's anything specific to the Darky parts of the OS).
Basically, the phone starts to stutter and lag, then starts slowing down horribly until it will be totally unresponsive. The OS and apps are still running (if I'm playing a game sound still plays)
Anyway I think I've narrowed it down to something with the Micro SD. I reformatted it and today it froze again after being super slow for about 15 minutes. So I rebooted and then unmounted the card. So far the phone's fine.
So does anyone know if a bad or faulty Micro SD card could casuse Gingerbread to display this behavior? It's worth mentioning that other than the freeze-ups, it doesn't display any obvious r/w problems. Nor does it display them when mounting in the PC
Thanks
EDIT:
Here is the thread where we're discussing the freezing problems. I didn't put this question there because it's basically a different question:

[Q] SD Card random deletion issues.

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

Frequent freezes/reboots after upgrading Spice Dream Uno H to Marshmallow

Hi everyone,
I upgraded my phone to 6.0 this morning, and have been facing issues ever since. The phone keeps freezing or rebooting at will. When I first tried to format my SD card (a class 10 Strontium Nitro 32GB purchased 2 months back) as internal storage for the first time, it got stuck for a long time and I had to do a factory reset and format again. After that, I moved all possible apps to the SD card, but every time I try to access a few of these apps (official Twitter, Truedialer, AdSense, etc) the entire phone will freeze for about a minute and then reboot for a very long time (over 5 minutes). I am terrified of opening any app on the SD card right now because it might trigger the reboot again.
Is anyone else facing similar issues on their Android Ones?
The battery life has also seemingly degraded, and once the phone completely shut down because the battery suddenly went from 40% to 0%.
After last year's Lollipop debacle and now this, I am really disappointed with Google's quality assurance. Marshmallow was supposed to be all about stability.

My experience is pretty opposite to yours, my canvas is working flawlessly, and battery life has significantly increased. There is no sd card problem for me and app permissions and doze mood is best of the picks...try to reset your device

Install android m stock rom again and after install format your memory card for internal storage using wait when memory card is formatted don't shutdown your mobile try this it will work
I am also facing random freezes with Spice Dream Uno on MM.
So I factory reset again this morning, formatted the SD card as internal storage one more time, and installed a few apps to the SD card. Things look much better than yesterday, so I am slowly adding apps and checking if any of them misbehaves.
I can't believe there isn't an option to auto-install apps to the SD card for sprout4 models.
Thanks for your replies. :good:
There are a lot Fc's on sprout 8 on root too I guess it has to do something with costom kernel apparently stock rom works perfectly
same problem Here in Spice Dream uno
I am also facing random freezes with Spice Dream Uno on MM
Freezes are back
They are back. At this point, I don't know what else to do except swap my SD card and see if the new one fixes the issues.
I can confirm this on Sparkle V too.
Making ext_SD to be used as internal even on Class 10 makes rebooting to take a hell of time.
I can confirm this with my canvas A1 running stock Marshmallow and Nitro Class 10 memory card.
It works flawlessly as external storage. But often freezes when used as internal.
I experience this on low battery usually.
Use sd card as external no problem but crashes the other way around same here

Tablet crawls to like zero performance. SD card culprit?

This is a strange one. I bought one of these a few weeks back:
http://www.amazon.com/Silicon-Power...&redirect=true&ref_=oh_aui_detailpage_o00_s00
It's been working fine for me. Yesterday, my tablet just hung. Like I could barely click on anything, and then when I could, it only seemed to last for a few seconds, and right back to totally hung. I had to force reboot my tablet, but it was not very long upon reboot that the same thing started.
I turned to google for advice, and one site recommended un-mounting my sd card. Well. yeah, doing that seems to have resolved the problem. It has been running completely fine ever since.
My question: Does this mean I have a bad SDcard, or is the problem with the tablet? Is there a way to know. I don't have the same problem when I plug this sd card into my windows computer.

Highly likely the sd card.
I bought one of those also and had the same problem. I returned it to Amazon for a refund.
Stick to decent cards like Samsung Evo.
Use cards which are U3 rated for fast writing.

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.
