[Q] Recommended SD Card! - Galaxy S II Q&A, Help & Troubleshooting

Which micro SD card should I get for my galaxy s2?

Patriot LX Signature Flash, 32GB microSDHC Class 10 (PSF32GMCSDHC10)
This one is a very good card.

Never had any problems with Sandisk cards. I can get a class 4 32GB for less than $50 AUD which is plenty for me.
Unless you want one of their new 64GB micro-SDXC cards for ~$200 ? ;-)
Or you could fork out a bit extra for a class 10 like Tazer mentioned (around $85 AUD for me).

Like you, I faced the same problem and did a little google. I decided on a sandisk 32GB Class 4, which works like a charm. Smooth recording, etc.
A person on androidforums said a class 2 was enough though.
In the end, i guess it depends on your budget and requirements

amazing info guys thanks!

Personally i'd go with class10. Transferring files onto a class4 card is a slow process !!

we'll see where I get the most for my buck on boxing day =P

Using Samsung's 16GB Class 6 MicroSD ever since I bought my I9100. It came with a Card Reader as well. The package cost me INR 900 ($19). If you're from India, you can order it online on Homeshop18.com!

But a lot of the user reviews of class 10 cards say they are slower on the phone than a class 4 . Thats due to poor random read write speeds .

erm dont mind i ask but why do we still need a memory card when the phone already had 16gb? and is backing up to sd card better then backing up to titanium backup? And also i had seen people memory card became corrupt and they are unable to use it, how it became corrupt?

Well, some people have a really HUGE music collection. Others , like me, like to download games / try ROMs. So the space is really needed but if you can live with 16GB, good for you
What do you mean by backing up to the sd card? As in a nandroid backup?
No idea about the last question though.

because i have seen people saying that they can move their backups or even apps to their memory card, so i just wanna know is there any advantage of backing up to your memory card or cont using titanium backup to backup my stuff

You can set Titanium (and CW Recovery) to make backups to your external SD. Saves heaps of space on your internal card.

I don't know why memory cards sometimes become corrupt. That's never happened to me before
Maybe you could put it in your PC and run Windoze checkdisk on it (if you have a card reader) ? Windoze might (probably a long shot) be able to fix errors on the card.
If I had a situation where a card was giving me problems, I'd probably buy a new card rather than mess around with it. I realise that doesn't help you if you've got a lot of stuff on the card you'll probably lose tho
A good thing to do is to keep a copy of all the stuff on your external SD card on your PC just in case it goes bad (as well as copies of your EFS, Titanium & Nandroid backups), that way you wont lose everything if the card dies.

sry for the noob question but can anyone tell me if what i had written down is correct?
undervolting meaning i can make my battery life last long?
overclocking meaning i can make my phone more faster but also drain my battery faster?
if i'm correct can someone please link me to a guide or page where i can see how i can undervolt my phone? i had already root my phone and try out quite some of different roms and kernel. current i'm using Galaxyzero rom and phenomenal kernel but my battery life still drain out quite fast. from a 100% charge to less then 10% took me just less then 14hours. so please i really do need some help out there. thx to whoever is able to help me?

Please don't ask the exact same question word for word in multiple threads

Issues with my SD card

Hello all,
I've bought 8GB SD card and used it on my mini pro, I faced some issues like:
1. Alot of programs suddenly crash
2. Wireless connection gets dissconeccted automaticlly
3. The whole Android software get crashed and the screen goes into black, then this can't be solved if I didn't remove battary and reinsert it.
I Tried to check the SD card for bad sectors and problems but there were nothing.
Any Solution?
NOTE: I have another SD card (2GB) and it dosen't make any problem when in use.
If you remove the card the problems persist?

SDcard has nothing, that could affect wireless connections at all.

It happen to once with my cheap 4gb card when i paired with nokia n82.. Till now i don't know why the phone keep refusing to recognize the card. The irony is, the "rejected card" works normally on my current phone "sk17". it left me scratching my head.
If you can return it, return it. If its not worth it, just get a new one. Basically, you have done everything on you end, so its definitely the card's fault.

Check for SD card class,its written on SD card.If its less than Class 6 then you should buy SD card with class 6 or higher.
Second you should not place large files like multiple blueray pictures or multiple songs in single folder.And last you can speed up SD Card read,write speed by using SD booster of Root tool box pro app to make your SD card faster.
I thing class is not so important. I now using few year old 16 gb card class 2 without any problem
Sent from my ST15i using XDA
Weird but I have no reason not to believe you.At least you know that the problem is the card,so either return it and get a new one or buy a 16Gb instead.They re already pretty cheap! Opt for a class 6+!

Why should I avoid putting multiple songs in one folder? I have put like that and my sd works fine eh??
and the other thing if you had apps in the other sd which was 2gb and u put the 8gb one without transferring them to the 8gb card the apps should not work. Android system failure sould be a problem of memory management. Check whether you had filled ur card.
and yea I think the best solution for u if u have tried every thing, return the card

[Q] Icons keep changing to little green android guys

Hello everyone, I seem to keep having an issue with my desktop (no sure if that is the right word to describe the main pages where you icons and widgets are) icons will change to images of the android guy. It seems to happen randomly and frequently when I reboot my phone. It never happened on stock but I am currently running Team Perfection's Objection #2 with its RC1. I have flashed it twice and still have the same problem. Both times I flashed, I did a clean install. I flashed the dalviek cache, wiped the partition, fixed permissions...... This issue has also come when I tried Goldie 5 rom also. So far to remedy the problem, I delete all the icons and then I add the shortcuts back. Not a deal breaker, just annoying and I am curious as to why. I have tried searching on the web and in the forums here but having no luck. I think it may be the way I'm typing in the search. Any help or suggestions will be much appreciated. I have included a screenshot of my issue.
p.s. this is my first question post so please tell me if I need and how to improve my posting skills.
Go into settings/applications, and move the apps from sdcard to phone.

They will show like this when the OS has lost connection with your sd card. You can.go thru setting unmount and then remount your sd card and they should show up. Not to be a doomsayer, but there is a possibility that your sd card is getting ready to go out on you. Mine exhibited the same thing and then died 2 weeks later.

Please dont say that! This has been happening to me too, and I figured it was because the apps were on the SD card....so if the card dies, I will loose everything wont i?
Unmounting the SD card and remounting didn't work but moving the apps back to the phone worked. I may invest in a new sd card with a higher class. I am currently using a san disk 4 class. I want to keep my apps on the sd card because the partition seem so small on the phone and I find it easier for backing up purposes.

Not saying it is absolutely going to happen, but that is what happened to me. New card, no crazy icons.
Would at least back up everything important from the sd card.

I mean its possible. I learned from loosing over 500 pictures and videos how important it is to back up SD cards. There are many apps that can back it up for you. I personally use Google+ for backing up pictures and videos only when connected to a charger.
When my SD crapped out, it put my phone into a boot loop, which made me panic since I was an avid flasher on my atrix. Not sure every SD card acts that way. Of course, once removed, phone booted up normally

This phone has almost 2GB of storage memory for apps. And that is about the most I have seen for about any phone. So if you are using it up you must have alot of apps. Maybe too many as the phone is having issues keeping them alll in memory. Had similiar issues to this on previous phones when they were simply over loaded.
Also, I don't believe it is your SD card going bad. The phone doesn't save/move apps to your external (physical) sd card. It saves them to the built in internal/usb memory which is about 11GB. Even the EA/Gameloft extra downloads are saved on the internal/usb memory. You can connect your phone to your computer and see this. However when you unmout the external sd card the apps disappear. So how the 2 are linked is unknown to me. But that link may be the issue.
Got a 32 gb card just to be safe. I need a larger card anyway so I'll throw this older one on my camera. LOL
Thanks for saving me time

[Q] Is it me, software, hardware or a bad SD Card??

I bought a no name 64GB Class 10 MicroSD card to replace my 32GB but I can't seem to get my data transferred over cleanly. I've formatted it numerous times (exFAT) both on my PC and my GNote. I have the 32GB card backed up to my PC. I've tried copying from my phone (32GB) to the PC (64GB) and vice versa. Sometimes it will go all the way through without a problem but always only some of the files and folders are copied correctly. Other times, it will throw one of several different errors and the stuff that looked had been copied will vanish. For example, this morning I was copying certain files, essentially one by one and checking in ES File manager to see if they were on the phone's external SD card (64GB) and they were. Then after doing this for a bout an hour it would hiccup and everything I'd copied over and verified with ES File Manager would be gone!?
If it matters, I'm running Windows 8 PC with 4GB ram and 1.31 TB of HD storage. On my Gnote i've tried it with both a stock ICS TW ROM and JellyBeer 4.1.0 with no joy. I've done a bunch of searches here and on Google but nothing seems on point. If it's a bad SD Card, how do I test for that?
When I had a weird problem like that it turned out the SD card was fake. This program determines your actual SD card size.
http://fightflashfraud.wordpress.co...ld-standard-in-detecting-fake-capacity-flash/
Other then that, fat32 is what you should use in Android. Maybe even try letting the phone format the card through settings/ storage. Be advised there will be data loss so backup anything beforehand.

The validator is certainly in my toolbox now. Thanx again. It takes forever to run on the large capacity drive but it was definitely worth. The white lettering is beginning to smudge.

[Q] Best way to get more storage space?

Hey all, I tried looking this up already but I couldn't find what I wanted. I've nearly used up all of my phone's 9 or so gigabytes, and now I'd like to know the best way to get more room. I've deleted a decent amount of bloatware, but my misc. files still hovers at about 6.4. I've also thought of getting an sd card, but I looked it up and it seems like many people have problems with those on this phone. I'm not really sure what the best way to go about this is, so I'd appreciate any help.
Flash the Google edition ROM. Or you can get a micro SD card. Maybe use Google drive?
If you're in your return window, return it and get the 32GB version.

Buying an external SD card is definitely the answer.
I bought a 64GB SD from Sandisk, I was having problems just like everyone else. The card would unexpectedly unmount every few minutes, so I couldn't listen to music without being interrupted. However, Sandisk is fully aware of the problems its cards are having with Samsung phones. I contacted them, they sent me a new card with an "updated firmware". I have had the card for nearly a month now, and haven't had any issues with it. They have solved the problem.
So if you buy a card that has come right out of the factory, you, too, should have zero issues. If you buy one that is a little old, you can contact them and they'll send you a new one that WILL work.
You have very few options without a SD card. 9 GB of storage is far too little, and cloud storage is just messy. You shouldn't have to rely on mobile networks to have access to your data.
Hit thanks if I helped you, and good luck if you decide to buy an SD card.
I wish I would've waited until they released the 32 gb version, but I'm well past the return date. I've deleted most bloatware I don't want, but I still would like to keep some of it, so I can't flash the google edition rom. I'd rather just delete it myself, but I'm using root explorer and I heard that causes problems. I'll probably just get an sd card and update my phone. I don't know how seeing as I've rooted it, but I can worry about that later!
I still don't get how there can be so much bloatware. I know there's the OS, but that can't be more than 4. Most of the bloat apps aren't even that big. Anyways, thanks for the help.

Your misc files should not change if you delete bloat. If it did decrease in size, that would be a major cause for concern, as those don't represent the bloat you deleted. Debloating really isn't going to gain you any usable space because the apps that you are deleting reside on the system partition. Bloated or not, that partition is going to remain the exact same size regardless. Deleting apps from it does not make that space available to user apps or storage- it remains available only to /system.

No, you won't have to update your phone. Your phone wasn't causing the problem. When I said they "updated the firmware" I was talking about the SD card. If you get a Sandisk card straight out of the factory now, it should work with your S4 regardless of your root status or your custom rom.
So to be perfectly clear, Samsung didn't update its firmware, Sandisk did.
If your SD card doesn't work, simply contact Sandisk and they'll send you one that works. Simple as that. You WILL NOT have to change ANYTHING with your phone.

I know little about how moving apps to sd cards works, but I was saying that because I rooted before the new update so I'll need to update to move apps unless apps2sd works.
najaboy, I have a question because you seem to be knowledgeable about this. How is it that just system memory takes up 6.38 GB? Is it because of Samsung exclusive features like touchwiz and all those airgimmicks?

AH! Ok I see what your saying. I don't think it is necessary to lose root to move apps to your SD, though. I've seen a lot of positive comments about Foldermount. Foldermount should free up space in your internal storage no problem. Check it out.
I'm also pretty confident that soon the rom devs will incorporate the update that Verizon put out into their own roms.
And about your question to najaboy, the 6.38 GB is everything that makes your phone's software. Yes, air gestures, smart stay, all of that. I do find it a little misleading Samsung advertises a 16GB phone, but I like keeping my data on a card anyway.

SD card failure

Ok so twice now my SD card has become corrupted and have lost all data that was on the cards. At first I thought it was the SD card that I first bought since it was a cheap no name brand, so I bought a SanDisk brand and it happened again. I'm not really sure when its happening or what's causing it to be come corrupt. Has anyone else had this happen to them? I read somewhere that flashing a lot of roms or kernels will corrupt your SD card, is there any truth to that? Also I'm rooted running skydragon Rom with the skydragon kernel, I do use some xposed modules. What can I do to keep this from happening again?

Ok so twice now my SD card has become corrupted and have lost all data that was on the cards. At first I thought it was the SD card that I first bought since it was a cheap no name brand, so I bought a SanDisk brand and it happened again. I'm not really sure when its happening or what's causing it to be come corrupt. Has anyone else had this happen to them?

i dont know whats causing it or how to stop it, but that flashing theory is complete crap.
ive flashed several hundred times a year for the past 4 years and never had a corrupt card.
the cards have a reasonable life expectancy, so over time they could basically wear out and die (never had this happen either), but nothing ever flashes to the card, so i cant imagine how that could cause issues.
the first thing i would do is use this utility to verify your card is genuine and not damaged. if it passes the test, then i would start isolating the most recent apps you have used or downloaded that may write to the card, including but not limited to the file explorer you use to move files onto the card.
eliminate or add a couple a day until you can isolate the causing the corruption. its going to suk, but if there is an easier way, im not aware of it.

I'd install SD Card Monitor from the play store to see if the card is unexpectedly unmounting periodically. I have had a device that had a problematic SD Card Slot and until I used the SD Card Monitor App I did not know that the card was getting a "Bad Removal" as the app calls it periodically. A "Bad Removal" at the wrong time could easily cause card corruption.
FWIW, I also never do nandroids directly to the external SD. I backup to the internal, and sometimes I manually move the backup to external from within the booted Android. Most of the time any more I just keep the backup on internal though. I seem to have much less often corruption of my external SD card since I started doing this.

^^^^^----- THIS!
If you are constantly backing up to your external SD, especially nandroids and you flash new ROMs like it's going out of style, you WILL reduce the life expectancy of your SD card.
SD cards have a limited life span. The more you write to them, the more wear and tear you do to them. I limit my writing now to adding new documents, copying new music and that's about it. I also store oft-used utilities there or images to flash to my phone, as well as the utilities for them, but I do not nandroid to it.
All my photos are stored on my internal memory.
I have had SD cards go out within a year. That was when I was doing a ton of nandroids to it, and in older phones, back when you could move apps to the SD card, those would go out as well since I was constantly writing app data to the SD card instead of internal memory.
How soon did they become corrupted btw? Within days, weeks or are you talking over a longer period?
Thanks!
Handling and Maintenance
A lot of people touch the contacts on the bottom of the card while they inset them, the oils from your fingers will create barrier between contacts of the phone and the card and it can cause file corruption. so I recommend washig your hands with soapy water, then pulling out the card and spraying rubbing alcohol on your sd card and drying it on a clean cloth and then holding the sides reinsert the card.
2nd thing is people don't format the card once it is in their phone. I absolutely recommend this as it is necessary to remove fragments from manufacturing formatting.
I have NEVER had a card fail me by following these two steps, and I've transferred thousands of songs and movies, and roms and backups over my cards through the years. The latest is a 32gb Samsung Evo Micro SD and i've NEVER had a problem even writing 4K video to it with my G3. Usually file corruption is user error. SD cards need maintenance. and if you copy and delete files constantly, including backups, I recommend a reformat of the card in your phone AGAIN as file fragments are left over and will cause corruption. MD5 sums are big because people don't know how to format regularly. Cheers
most of whats written here are absolute myths. Apps won't permanently corrupt your card, neither will nandroids and the cards if they are not cheap fakes are good for 10s of thousands of write cycles. What will damage your card are physical impact pressure, heat, and static electricity, bad formatting, bad partitioning and simple failure which does happen occasionally. Obviously removal and transport expose your card to more risk of physical damage.
