[Q] MicroSD

Im going to change to a 32GB or 16GB microsd card since the 8gb comes with the device is a little too less for me,so some questions here..
what to notice before i buy the card?
is there some card which is slow some is faster?
and what apps i need to use to backup my apps on the card im using right now.
and last, I did register the premium navigation with the voucher given , so the license in on my device or my card?
thanks in advance

Just copy all the files from your current card to the new card via a PC. I did this with MyPhoneExplorer full SD card backup and copied the files back to a new card via Windows explorer.
Speed wise it depends on the class rating of the new card. There's a post with SD card benchmarks on the forum here.

SD card problems

I am having problems with my SD card. I used to have a mytouch, and I bought a Sandisk 4GB back then. When I got the S2 back in Decemeber 2011, all i did was format the micro card to work. The S2 shows that its there under Storage, but i have always have difficulties actually using it. You will see that it has some used into it. I can only reach it through USB connection and transfer file that way. However, whenever I use any programs which can be install under SD card, it will not do so.
As you will noticed below i have a problem call App 2 SD Pro, which it will only show both memories with my phone, Storage and USB, which is the same phone memory. By no means, its finding the Micro SD card. Can anyone tell me why is this? This phone is not rooted and i have only 2.3.6.
Thank you in advance.

If you look through your list of folders under /sdcard, your micro sd is the 'external_sd" folder.

Yes that is true. Is under External SD card. My question is, why are some programs, mostly all, having difficulties to find it? and can i have all for example game files, be saved onto my "external SD Card"?

What is the speed of your sd card?
class 2, 4, 6, 8 or 10?

How would i know that? all i can see on the card is, Sandisk 2 in circle, 4GB SDHC micro. Where else can i check? which class is best?

You have a class 2. It has been my experience that when you move an app to sd card, on this phone it uses the internal "USB" storage.

So what can i do to do the opposite? Meaning, using the actual SD card instead of the internal.

RAM EXPANDER will damage Phone?

Yesterday, i just try this app.
my sd card class 4 only... so i change the sd card directory to usb stroage / sd card 0
i don't use that space at all.
What i want to know is, will it damage internal space? or we so called usb stroage.

I'm not that an expert but I don't recommend you try the SWAP SD kind of APP because it may brick your phone !
CyanogenMod 10 Alpha 5™… XD

iv been using that app since the last 1 1/2 month.didnt hv any problem.but im using class 10 external sd.in my opinion dont swap memory from your internal sd card nor the phone memory.the swap memory is recommended only for class 6 n above.some said 8 and above.the internal sd card has a class below the requirement n if the internal sd card damages i really didnt know how to get it repaired since it mounted(CMIIW).just make swap from your external sd with class 10 or 8.if your external sd breaks u can easily replaced it.

swap thing is to risky for class4 microsdcard.

Please DON'T use your internal storage for this. This type of storage has a limited read/write cycle life span. By using it this way you ARE prematurely "ageing" this storage partition, and WHEN it fails, the repair won't be cheap.....it will definitely be cheaper to buy the correct class of extSD card and use that instead......

I have used this app, and there is some noticeable improvement, but only on class 10 cards. Anything below there will be little to no noticeable performance increase.
But you can always try.

Sd Card?

Which 32 gb 10 class for ZL? Samsung , sandisk , sony, transcend or which? Need to buy one soon.

samsung or sandisk both are good. Just so you know the 64gb sandisk works in our ZL's

i know 64 gb works but it's too costly for me so i am going with 32gb.

juct check my sig, im using 32GB UHS1 from sandisk and work well.

Me too. Iam abt to buy a card. But im scared that the card might get corrupted. Is dat corruption problem common in ZL too?? or only in Z?
So iam thinking of buying a Sony micro sd presuming it will not get get toasted!
So tell me a brand less prone to corruption
Thanks

When I got the phone, I just reformatted it using the phone. I never even looked in to what extension it's using. This was on 4.1.2, and it read it as 64GB then, though I believe the new update says it NOW allows 64GB. I just copied the card onto my computer, reformatted the card, and then put everything back on it. No problems up to this point, though I've only been using 4.2.2 for a few days.

I just picked up a 32gb Sandisk Ultra UHS-1 for it. (64gb was pretty spendy and far more than I really needed) I hope this was a good choice on my part, but judging by the comments it should be fine. I should have my Xperia ZL on Wednesday and will report back how it works out. (Just ordered it, got free overnight shipping)

I am using SanDisk 32 GB UHS-1. Just reformatted it with phone to see, what file system is used with new firmware. It is formatted in FAT32 by default. No problems so far.

It Works!!
Bought Sandisk 32GB 10 class 1-2weeks ago and it's working without any problem. :good:

Whatever you do, be wary of corrupt/mislabeled SD cards!
When you get your SD Card, always first check it out with a tool like H2testw or Check Flash and make sure that the reported size (32GB, 64GB) is indeed the actual storage capacity.
I once bought a 16GB flash drive that could only store 8GB of data; exceeding this 8GB would corrupt the data on the drive. H2testw proved that cheap deals online usually come with a price...

SD card write erros

I have Sandisk 64GB ultra class 10 micro SD card and Samsung Galaxy S3 phone (Cyanogenmod 10.2). I regularly encounter inconsistent write errors when trying to copy big directories (~4Gb, ~300 files). What can be possible cause of those errors? I tried to do that on PC - everything worked fine.

Maybe it is because of you format of your memory card? Do you have it in NTFS or FAT32?

Maybe because you format?

Yeah maybe you should format it and try again.

format it using the phone, you shouldn't have a problem, otherwise it could be the memory card, although i've used sandisk for over 20 years, from 8mb tf to 128GB microsdxc, not a single problem.
