Only if they are not dependent upon the touchwiz framework. For example samsungs internet browser can be installed on any device (example of non touchwiz dependent app) where as gear vr only works on samsung roms (touchwiz dependency) . It wont hurt to try you will just get non functional app or fc. NOTE!!!! I STTONGLY SUGGEST NOT FLASHING ANYTHING ANDROID IS DEPENDENT UPON FOR BOOT OR TOUCHSCREEN FUNCTIONALITY (SYSTEM UI, documents ui....leave anything with ui in package name alone. A phone without the ability to be interacted with would seriously suck. Obviously backup before trying system apps ....the camera isnt going to work ....im doubting voice note will either, but i havent tried either (the cam im certain wont work we have been looking for a working one since march)

I am one of many with the black spot on the edge of the screen. Do a quick search and you will see this is a prevalent issue. Samsung's solution? Send the phone in for service and be without your device for seven business days. This is unacceptable. I guess quality continues to dog samsung. I have to admit though, I have seen others with much larger spots.

Repairing a corrupted SD card.

If the SD card is corrupted then it will be because it has boot sector errors. Download DriveRestore Professional and you can scan your corrupted card for errors... you can then repair the card's errors when the product is activated. You can download a free trial at: www.pcrecovery.com/driverestore
[General Questions and Answers] heliosismagic:
don t format in the name of GOD!!!

Please all keep in mind>>>> drive recovery pro is a nice solution,but formatting a hard drive is ok,and important.NOT A SD CARD!!!The continous files are different from the usual hard drive files!!

NO NEED FORMATTING!!!

In fact>>formatting an SD card lower the life time of the card with a good year or more!!Anyhow they made to survive only around two years!!!

The continous upload and erase sssions are killing the SD card.BUT FORMATTING IS TH BIGGEST KILLER.Check the experts,what they say???

Corrupted cards can be deffected from factory as wel,but drive check and restore is the best.The sectors are damaged,and not the fragmantation....

[General Questions and Answers] Brian 500:
Repairing a corrupted SD card.

DriveRestore Professional will not re-format a corrupted SD card. Formatting is NOT recommended as formatting will

erase

all the data on the SD card. DriveRestore Professional will analyse the boot sector (that ALL drives have e.g. FAT16 and FAT32 file systems on an SD card), it will detect errors in the boot sector and then repair the errors. When the card is repaired, ALL the files will be accessible and the card is fully repaired.
[General Questions and Answers] mr_deimos:
Sometimes the filesystem on the card gets corrupted. It can happen for example if the card was ejected while a file operation on it was in progress. When that happens you might have trouble accessing some of the files, loading times for some directories in file explorer may be very slow.

You can attempt to fix it using the desktop windows' built-in chkdsk utility.

Open up command prompt (start->run->cmd.exe) and type

chkdsk /X /F <SD card drive letter>

My SD card reader is X:\ drive, so i wold use the following command:

chkdsk /X /F X:

SD card reader is recommended, but probably not necessary because it should also work with WinMo's built-in USB mass storage function or wm5torage.

Under linux you can check/fix the card's filesysterm and in some cases undelete a file using fsck.vfat or dosfsck (single tool, two possible names). Refer to its help for more details.

I only recently became a (sort of) expert on this as I had a corrupted NTFS bootable partition on my macbook pro with a messed up Master File Table. Man, that was a nightmare.

Anyway, the answer to this question varies greatly depending on the filesystem and the type of corruption you have. Standard Chkdsk might work (the windows utility) although I admit I have no idea how well that works on flash removable media.

Other good options are TestDisk, and there are some other free options out there.

Depending on how important your data is to you and how severe the corruption is you may need to go with a paid application. This is what I had to do because Master File Table corruptions in NTFS are particularly nasty (although some versions of them can be corrected by TestDisk). I recommend GetDataBack which worked great for me.

In any case, try TestDisk out because its a very powerful tool and it is totally free. Read up on the documentation before playing around with it though, because you can cause irreparable damage to any one of your disks if you don't know what you are doing. Ideally make an image of your card using dd (built in linux utility, just type 'man dd' at the cmd line) before attempting to fix it so you can't do anything you can't undo.

[General Questions and Answers] Jimisballjohn:
Hello everyone, just wanted to share my experience with two 32gb Samsung evo cards, a plain and a Plus one. I used them as adoptable android storage and after some time (maybe after 2 years for the first one and a year for the other) they both became corrupted and write-protected. I didn't want to experiece the fuss of replacing the items, so I tried EVERY PROPOSED SOLUTION regarding corrputed SDs. So, I tried to format them with Windows Explorer, having inserted them one time in a Card Reader and another in my oldie Nokia N95. Nothing happened and I received the error that the cards were write-protected.

I tried the diskpart and Disk Utility methods; however, the results were the same as above.

Time for EaseUS, Partition Wizard, SD Formatter Tool and HPUSBTool. Unable to format as well.

Ultimum refugium was a VM running Debian OS and gparted utility. Even this application was unable to format these two stubborn cards.

In conclusion, I resolved my problem by replacing these two cards from the merchant I bought each one. It is obvious that some sort of physical damage is unfortunately occured by using the card as adoptable storage. From now on, I am certain that I will not use this type of partition ever again.

[General Questions and Answers] wian:
You may be able to fix a corrupted card using the latest version of the official formatting tool: https://www.sdcard.org/downloads/formatter/

A full format takes a long time. You can first try the "Quick format" option. But if your card is screwed you probably need the thorough format:

Choose the card and select "Overwrite format" and tick box "CHS format size adjustment" then hit Format.

ALL DATA ON THE CARD WILL BE LOST!

I then put it in my Linux machine and ran badblocks destructive on it, one run of each of the 4 bit patterns (took 30 hours!), and it said 0 errors. Does that mean it's ok to keep using?

Dont know what tools service center persons have. They can fix the SD card if not, they replace it.

I have strontium 64GB micro SD card. It some how got corrupted. Some chinese and unknown character and symbol was shown when connected to PC, then I ran error check and repair the errors, every thing was cleaned. I can see the files of my SD Card, but, the card became read only. I can not write data on it. Even in PC when right clicking any files, no "delete" option is available.

after trying every possible methods and tool available on Internet, atlast I had to go Service center.

He took SD card, went inside and returned in couple of minutes. Now my sd card was repaired.

But, when I inserted micro SD card in my cellphone it is now detected as Samsung SD card.

I dont know what he did. Possibly he might have write some different firmware. (I have heard that sd cards too have some micro controller and its firmware to control the main storage unit. If that firmware somehow got.corrupted, then damaged sd card is shown, which can be repaired by reflashing firmware)

[General Questions and Answers] SyCoREAPER:
Word of advice, unless it's an expensive high capacity card, it's landfill waste. Chances of a card that badly corrupted being fixed are slim and being reliable even less so.
[General Questions and Answers] Snakeforhire:
As others have already mentioned : formatting is a big no-no with NAND flash drives -except when you need to switch to another filesystem (in this case go for the "quick format" option to lessen the damage done).

But a lesser-known fact is that using any journalling filesytem (among these are ext4 and NTFS) on flash memory is also a quick killer for it, due to the constant logging going on even when idle. You should always -when possible of course- use a flash-friendly FS like F2FS or exFAT instead.

Sometimes of course, there's just no say in that matter for the users. Just know that it impacts the memory's life-span 🙂
[General Questions and Answers] blackhawk:
Depends on how it was corrupted. If it happened spontaneously it's likely trash.

If it was due to user mismanagement, it can be reused.

However I agree if there's any doubt of its integrity it should be replaced because critical data can not...

A new card should come straight online and formatt on the phone with zero issues. If it doesn't it should be returned. Otherwise it will likely continue to have issues.

I used a sdcard years ago converted to RAW in order to modify/flash/root a Nook tablet. I was never able to repair the card to normall usage. I used every trick I could find and nothing worked.
[General Questions and Answers] blackhawk:
Low level format will bring it back unless it's damaged. I've never worn out a flash drive, obsolescence is what kills them. ESD exposure can damaged them as well. Exposures are cumulative and can eventually cause a failure.

It large enough one time exposure can kill them.

They have limited ESD input protection.

A card that behaves improperly at the get go it likely has hardware damage; even if you get it working it will continue to cause problems unpredictably.
[General Questions and Answers] Droidriven:
I also have a Samsung 32GB that worked flawlessly for years in several devices until one day I got a new device, ejected the card and inserted it into the new device, it was detected then immediately lost detection,when troubleshooting and putting it back into the previous device, completely dead, never got it to show any signs of life again, no detection, unable to format, no recovery software could do anything, just....nothing.
[General Questions and Answers] blackhawk:
Best to always first format the card in the new device then populate the card through the phone.

It may have been from ESD damage. Touching an earth ground immediately before handling will bleed off any charge. Wear cotton. Room humidity should be at least 40%. If you can feel, hear or see static electricity it's already enough to cause damage.

Sim cards are even more susceptible to ESD damage; handle them like a stick of ram. They're dirt cheap but a failure will cost you time and trouble maybe at a critical moment. Almost all sim card failures are the result of ESD exposure.

Cheap, unknown, pirate cards tend to be faulty. Try inserting the card in the phone, format it. Turno off and on the phone. Does the phone propmpt you to format it again?

After formatting again, shutdown phone, remove card, add it into a computer. If it recognises the card, copy files/ folders on it. Several gb:s. I had a 128 gb card and I wrote about 20gb on my. Unplug from computer, reinsert. Are the files still there? Can you access them?

Insert card into phone again. Will you see the files on the card at all? Do you have to format it?

If the steps where I asked a question fails, card probably card faulty. Usually it is enough when the first steps fail to indicate a faulty card.

There is software to check card through reading/ writing data to the card. I takes time when it does this. It took 3-5 days when it tried writing on my faulty cards.

It detected faulty parts on the cards after 7gb on the card with storage capacity from 128gb card.

Hope this helps.
[General Questions and Answers] Snakeforhire:
There are a few utilities which can (my favourite is File Scavenger on Windows), but it's a coin toss at best, as NAND storage doesn't retain erased data like a magnetic hard drive does : in the latter case the data is still there but the entry pointing to the blocks of data have been taken out from the index table (the FAT on exFAT, and inode superblock on Linux/Unix filesystems. NTFS has a more elaborate indexing system than FAT-derived filesystems, with redundant copies which make it easier to recover files. Sadly, journalling filesystems like NTFS and ext are killing flash memory cells at a far faster rate...), so at worst you just need to scan the whole surface to look for the patterns indicating the start of a data block.

But on flash storage, once a block is marked as "deleted", the flash controller pretty quickly issues TRIM commands, which once launched overwrites the whole block with ones (flash works the opposite as harddrives : to write on magnetic media you set a bit from 0 to 1, but on flash you set it from 1 to 0) so it can be allocated again ASAP upon the next write command...

Which basically means that if you don't realize your mistake and power off the SD card right away, and only power it back on once it's protected behind a write-blocking adapter, your data will be gone forever in mere minutes, if that... :/
