OK so I've been running many version and builds of android since day one on my tmous hd2. At first it was with the stock 16gb sdcard, (till it got corrupted, LOL) so then I switch to a 2gb I had around. I have only formatted this 2gb card once in the begging and never again.many times I have deleted the android folder and many times I has switch to new builds ( I think I try everyones.latest I been using n very stable JDMS 1.3) n haven't had any issues. Like freezing or SOD. Now two days ago I help my friend with his and his wife's tmous hd2 with the 16gb card. So I did a fresh format fat32 then flash the same rom (ozDroid) and radio I been using for months. It results they are getting freezes and occasionally SOD. So for a test I took my wife's tmous hd2 with 16gb card did the hole setup an guess what the freezing and SOD is the more often..when I don't get any with my sdcard 2gb. Could there be an issue with high capacity cards. And could that be the reason why many tmous have the more problems with freezes and SOD

I use stock 16gb and dont have those issues.

this is common knowledge in the IT field. the larger the card, the more slowly it will write and access small files, such as the files needed to run android. take 100 small text files and copy them to a 256 thumb drive, and an 8 gb thumb drive. you can copy them all to the 256mb drive, and delete them all again, before the are all copied to the 8gb thumb drive. the 8 gb drive, will work much faster copying an .avi, or large file than the 256, but it sucks at lots of small files.
but it's good that you're posting your exp here. many people would not know this otherwise, and may stop experimenting with android due to frustration, when all they need is a $10 2gb card from walmart.
another couple tips when dealing with solidstate memory. just like a harddrive, files can become fragmented if you have multiple tasks or file transfers going at the same time. to avoid this, make sure each is done before starting another set of files. next, do not defrag solid state drives. they only have a limited amount of times they can read and write to each sector, and defragging, and excessive copying/deleting, wears down the material, and kills sectors of the drive. and last but not least, watch your battery. just as it says not to attempt an install with less than 50% battery, don't run your phone down to a dead battery when possible. because your booting of the microsd, it's constantly being accessed by read and write functions, and if the battery dies before it finishes writing, you get corrupted files, and you'll have to do your install all over.
No lockup or freeze with 16GB.

Same here. 16 gb SDHC, no problems.
I haven't noticed any difference between a Class 2 2gb, Class 2 16gb, or a Class 4 8gb - they all run about the same with not noticeable differences in boot time, smoothness, or SODs, even though the class 4 is 2x as fast.
hi guys,
before you post any comment, you can grab a none SDHC card, and do a comparison.
if you have benchmark software, please look at the "access time", the None-SDHC card always faster than the SDHC card. not the speed, but the access time.
after I change to 2GB SD Card, I never meeting any sleep, lag program with any version of roms.
if you don't have none-SDHC card, please do not make any conclusion.
16 gb class 10 kingston sdhc
works great
compaired a class 6 no name 8gb sdhc and the stock 16gb class 2 the class six lags less than the class 2 but the class 10 16 gb kingston is super fast
I am using class 4 8GB and 16GB, no diffrence found.
I can confirm, going from 16gb to 8gb, I've had far less issues with the 8gb card using the same setup. 0 SODs when I'd get them daily with the 16gb card. May or may not have anything or everything to do with it, but I'm sticking with the 8gb card. lol
My experience has been that performance has been about the same whether using a 2 GB SD card or a 16 GB SDHC. However, it seems that my 16 GB card was slower at one point because I had an excessive number of individual files on it. It's a double edge sword because you have all that capacity but the more you use it the slower it seems to run.
I had this issue aswell but I updated my radio to 2.12.xx.xx. and since then I have not seen any performance issue due to the SD card size.

That's very presumptuous of you.
I fixed all of my lag and screen freeze problems with a combination of setCPU settings, ADW launcher settings, and updating my radio rom.
Before I finished doing all of that this morning, I'd get a freeze from wake fairly often. Since then, not a single freeze, and trust me, I've been trying to get it to freeze up.
Believe what you will my friend, but punishing yourself with a 2GB card just seems silly when people are outright telling you that the size isn't the problem.
Good luck either way!

Yes ur are right with the new builds and using setting and programs like setcpu or even auto killers will help eliminate this problems. But I I said in the first post was that high capacity cards tend to give u more problems, using my 2gb (I think all the way to 6gb is non high capacity) I have no need for such adjustments to whatever build I use..u can read post 2, is very well explain there.

My 32GB did worked only one time, after first reboot i cant use android. But 2gb works like a charm
This arrived today from Amazon and good transfer speeds: 10MB/s write 20MB/s read via USB reader but much slower via phone connected over mass storage.
Everything transferred fine but now sense is very slow after boot up and when I scroll to another tab, sense hangs. Very disappointing. I'm running Dutty's V14 which is close evolution of the V3 ROM.

when i compare 8G class 4 vs 16G class 4, 16G will make my phone sluggish. does bigger size make it slower?
Not sure about that. Perhaps after start up if you've added lots more media and the phone has to index it all.
After some more testing the phone seems to work normally if I insert my 16GB card while the phone is booting and swap it for the 32GB Lexar once loading is done. I can then fly around sense with the card indexed correctly without the problems.
What could be the issue with booting the phone with the 32GB card inserted?
format the card, under sector allocation size, check the largest size, probably 64kb.
greatly increase speed for transfers and random access.

I've been eyeing that listing for the last few weeks (a few times a day) and every time it says "usually ships within 1 or 2 months." I guess the OP got really lucky then.
On the other hand, I saw Patriot selling a class 10 32gb micro sd for under $100.
Must have been very lucky yeah, it was in stock on Saturday, that's all I can remember lol.
I ended up going for a Kingston 32GB Class 4 card, was only £29.99. Seems too good to be true but I figured for that price it was worth a shot!

... or you could just stop by Hong Kong and buy it there. I picked up the genuine lexar 32gb class 10 for about 92 USD (720 HKD) last week Haven't tried using it yet in my HD2 yet, but probably will so I can try dualboot WP7 and Android
Yes I got one when I ordered and it was back ordered without any indication of time lines. Now they've put a couple of months on it for some reason.
Anyway, back to the topic. Why isn't my phone working with 32GB microSD card? I had a similar problem with my Sandisk (used with stock v1.66 ROM) and bought this Lexar hoping it would be ok with my phone. Any ideas? Tried reformatting it using the phone utility for compatibility reasons.

Absolutely not. Size doesn't affect the speed and neither does class. The only time you'll notice speed differences between classes is when you transfer media to or from the card while it's *NOT* in the phone. Otherwise they're all the same even though people say it feels faster/slower.
A little more info - I've found a way to get sense to semi behave like normal.
Once the phone boots I have to leave it for 3 or 4 minutes while the phone is very sluggish and not scroll or use sense (else it crashes) and after 3 or 4 minutes it then settles down and seems to act as usual. Except that for some reason the photos on the Footprints tab are all whited out.
Try reflashing a clean new ROM. I was using LeeDrOiD HD 1.5.1 and had loaded a bunch of apps and games on my Desire HD and sense got sluggish scrolling between screens. Now I've loaded LeeDrOiD HD 2.0.0 ROM with his latest kernal and loaded back more than 90% of my games/apps/widgets and the phone scrolls through home screens without a hitch. I kept everything the same on my MicroSD card I only reflashed the ROM and did a complete factory wipe in Clockwork Recovery.
I'd recommend to a Nandroid backup of your current ROM in Clockwork Recovery, then after that do the Clockwork Recovery factory wipe and flash a new clean custom ROM or Stock ROM. See if you are now getting much better speeds. If not just Wipe again in Clockwork and restore your backup then look for other options. If you still have slow speeds maybe try copy everything off the MicroSD card to your PC then reformat the card and copy everything back.
So, due to great confusion, I'm sitting here with an unopened Sandisk Class 2 32GB card, a Lexar Class 10 32GB Card and, arriving tomorrow, a Sandisk Class 4 32GB card.
What's the consensus from those who already have the Lexar MicroSDHC card? Should I open and install or wait for the class 4 ?
(Running Android NAND)
Since the last two minor updates I constantly keep getting the error message "SD card removed unexpectedly"... Anyone else experienced this?

Most probably a bad sdcard. There are lots of thread for this here. The solution is to get it replaced.
http://forum.xda-developers.com/showthread.php?t=2331434
I had similar issue and I claimed my warranty to get replacement.
Now everything is working great (so far).
You can also install this app named "SD card monitor" on play store.
It will tell you how many times you card has been failed.
My card was unmounting and then mounting itself lots of time. Mostly in deep sleep mode which make my phone battery drain faster.
I had the same problem in the end the SD card reader stopped working.event on utube to see how easy it was to fix.bought a new SD, sim card reader from eBay £5.70 an easy 10min fix no problems since

I had the same problem with a 32GB Class 4 microSD (SanDisk).
Replaced it with a Class 10 from Kensington and everything worked fine since then.
Please note that the faulty SD card worked fine on a Galaxy mini and mini 2 but I've tested it in the GS4 of my brother and he had the same problem as I had.
Might be a problem with the speed? Class 4 is slower and doesn't work in a GS4?
Just replace it with a Class 10 and it should work.
And a small tip... don't buy SanDisk... many users reported problems with SanDisk.
It seems sandisk sd card are problematic. There are lotsnof issue with sandisk class 10 specifically on 32gb and 64gb.

It seems to be the card tray loosing contact, I tried pushing on its lower right corner and then it would read. Got a I9506 don't know if its the same problem on all phones.

It is the best performance / value.
More info @ The best 64GB micro SD card for Galaxy Note 3
Samsung micro sd is my first choice its never failed me, second choice Strontium (Singapore) it just as good as Samsung and just a little cheaper (i was very surprised its performance and quality, i own 2 x 32gb its as fast as Samsung Pro class).
-Samsung still my first choice, Sandisk too many failure these days.

I use a Sandisk Ultra 64GB micro SD card and have recently removed it due to an overheat problem near the camera/flash area. I did not want to risk burning out the card (9months old) and I was told that removing the card might improve the over heat problem but it has not as of yet.
I have had my Note 3 for less than a month. In the time it has managed to kill two micro SD cards. I thought the first one was just and old card, but the second was brand new. Is this a common thing for these phones? Will T-Mobile replace my phone? Will they replace the SD cards their possibly defective phone killed?
Have you already tried connecting the SD's to the PC?
Try anyway to get swapped the phone when the micro SD aren't working on the PC. This seems to be very unusual!!

Do you live in a warm tempreture ?
Do you run games on it for extended periods of time ?
Are they a decent brand of memory ?
Does your phone run/feel hot most of the time ?
Lots of things could affect this, be sure to alert your carrier and make them aware that it keeps happening.
Ive had my Note 3 since release and a new 32GB sandisk Class 10 and its used A LOT, with no problems whatsoever.
Hope you get this resolved :good:
Usually warm temperatures don't harm that easily the SD, my note 2 hadn't had any issue regarding temperatures. Although when abroad in hot countries then phone heats up to 50°c without frying the interior. (I know it's not good but no other choice.

It's cold here at the moment. Middle of winter. I don't run games on my phone very often at all. I mostly just read e-books and take pictures which are stored in the now dead card. My phone doesn't really stay in any extreme temperatures. Texas winter is mild. Also they are good SD card brands. I can't remember the name at this second.

No the warm temps, cause the phone to heat up faster ( and stay warmer longer) thus*maybe* killing the SD card :angel::angel:

Lexar, at this time, are the fastest class of sd cards. They are a pretty decent brand . I know the 256gb class 1 sd card retails anywhere from $499 - $1000+...
Have you rooted? If you have, maybe the cooling control has gone wrong - processor running too high too long

Does your phone gets hot when there is no SD Card in it?
I've read some posts on overheating of the N3 but only if there is a SD card in it. Have you tried to factory reset your phone?
There are people saying that simply turning on the Power Saving mode helps, and others claim that Samsung Knox is the troublemaker and by uninstalling it the issue was gone.

The second card fried overnight while charging. Knox is disabled via root,
Then use it for a certain time without SD (an hour or so while playing or watching videos.) Then try with Power Saving. When not working try factory reset.

Samsungs kill SD cards. Anecdotal evidence is that Samsung's own MicroSD's seem to be more resilient. There is little to no benefit in using super-fast high end cards as the internal interface speed isn't fast enough to benefit from it.
Googling turns up many threads concerning newer model (S3, S4, Note 2, Note 3) Samsung devices frying MicroSD's.

If I read enough posts, most of the people were using a Class 10 memory card and faced this issue.
samsung told me over the phone class 10 is above the sdcard reader spec's so corruption is likely, they also said 64gig is not supported. Thats one reason I got a samsung branded 32gig class 6 card.

It's what I got, and I think that's right. Just to make something clear, S3, S4, Note 2 and Note 3, aren't supposed to support class 10. If you haven't got that issue good for you I don't have that issue either so I'm quite glad
