SD-card filesystem - G4 Q&A, Help & Troubleshooting

What filesystem do you use on G4 SD-card?
Why? What version of OS you have?

Do u do anything special to get exfat working? Do other apps see the exfat sdcard as an available source to access? I tried exfat but kept getting the error saying unsupported file system. Thanks
@welder73, not sure which is faster but exfat support larger than 4gb files while fat32 doesn't

About speed. I did'n see difference between exFAT and FAT32. About the same.
And I did'n do anything special to get exFAT. Just formatted micro-SD on PC via SDFormatter utility. I thing exFAT support may be available or not on different ROMs for different countries. I am on stock v10d-CIS. It's ok by default.
Also I saw then users flashed rooted system from one region to another stock ROM (SEA, PHL) - no exFAT support. May be answer is in some files in system (bin, etc) or in some files in another images from full KDZ/TOT.

ExFAT on a big SD card. Because it's a one way street on a phone capable of shooting videos that cost half a gigabyte per minute.
Stock marshmallow H815 EU.
Didn't have to do anything special other than format it using the native windows 10 format application. Phone accepted it no questions asked.
Speed wise don't expect observable differences over previous file systems. SD card hardware is the main factor.

You have to use Fat32 for SD cards smaller than 32 GB and exFat for SD cards bigger than 32 GB. Speed and reliability depends on the brand of the SD card. I used without issues a Samsung micro SDHC EVO UHS-1 (32 GB) and a SanDisk Ultra Android microSDXC, 64GB, 80MB/s, Class 10, UHS-I.

Is creating an exfat partition necessary these days?

Recently changed to a 32gb class 10 micro sd the other day and noticed in the latest TWRP that the option to format isn't there any more. Haven't partitioned a memory card since my og evo and was curious if things changed.
twrp format
twrp and cwm wont recognize memory cards in exfat format. it will only recognize ones in fat32 format. I used a program to convert my 64gb card to fat 32. There is a post on android central with link to the program. Its free too. Hope this helps.

[Q] New 64GB micro SDXC card not working in Galaxy S4

I just purchased a new 64GB SanDisk SDSDQX-064G-A46A micro SDXC card from Newegg:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820171773
The card works fine in my S3 and in my PC, but it will not mount in my S4, not even from Clockwork Recovery. Both my S3 and S4 are running the stock ROM, but the S4 is rooted where the S3 isn't. I went to the local T-Mobile store and while they didn't have an S4 to test my new card in, they did have a Note 3 which mounted my new card just fine. Additionally the 32GB card that was in the Note 3 mounted just fine in my S4.
What is going on here?
Format the card to Fat32 on your PC and see if that works.

There is no option to format to FAT32, only exFAT. Additionally, from what I read here Windows cannot format FAT32 volumes lager than 32GB.
http://www.ntfs.com/exfat-comparison.htm
A bit more reading and it seems the kernel that removes the SetUID restriction causes issues with exFAT formatted cards. Thankfully the fix is easy, just needed to install this exFAT module from recovery. The entire process is described here.

Here is a free windows utility which will format any size sdcards using FAT32.
Give it a try. Here is the direct download link: http://www.ridgecrop.demon.co.uk/download/fat32format.zip
Good luck!

There's plenty of software to format the 64gb card to Fat32. I'm running a 64gb card in Fat32 format right now.

shouldnt need to format to fat32 i have 2 diff sandisc 64g cards in tmobile s4's and they are exfat and work fine.. are you sure you are on stock kernel.. if you change it lots of kernels do not work for exfat.
I found guiformat made mine work. Same card and I was having issues, too.

OGP exFat support ?

Does the OGP support exFat ? I hate the 4Gb limit of FAT32. How can I overcome this limit ?

FAT32 supports partitions up to 32 GB. If you notice, out of the box the G Pro comes with a hidden partition and an 23 GB partition as Internal Storage. I have a 32 GB MicroSD card formatted as a single 32 GB FAT32 partition.
You only need ExFAT if you plan on using a 64 GB MicroSD card. Since LG advertises that the G Pro can support up to a 64 GB MicroSD card, then its likely that the stock ROM and kernel do support ExFAT. If for some reason it doesn't, then replacing the ROM with one of the Android 4.4 KitKat ROMs will surely do the trick.

Well, I bit the bullet and formatted my 32Gb sdhc card to exFAT and the OGP can read it flawlessly. I am very pleased with the results because I got rid of the 4Gb file size limit. The only small issue is that cwm recovery can`t read or write exFAT so I have to make backups to my internal memory and then move them to the SD.

How do you format it into exFat?

Well, it`s very easy. I put it in the card reader of the laptop and formatted it in the file manager of windows 7.

128GB Micro SD Card....Do They Work?

Interested in this phone for the specs, and the fact it has root...xposed etc...
Does this phone support and work with 128GB micro sd card.
Was looking at a 32/64gb model in Red.
Hello, this is ASUS_USA. Zenfone 2 model ZE551ML Micro SD Card slot supports up to 64GB
Yes, I am using the Lexar 128 633X in the 551ML 4/64
Here is a picture of the card and the phone.
You should be able to use any sdxc card as the 64gb card is sdxc... If a 512Gb sdxc micro sd card came out you would be able to use this...
And yes I have tested a sandisk 128Gb micro sd card in my xenfone 2...
I am using the Asus Zenfone 2 ZE551ML (4GB RAM, 32GB ROM) and can confirm that a Sandisk 128GB MicroSD card works fine . Mine is formatted with FAT32; i am not sure whether ExFat would be supported as well.

exFat is and OTG USB sticks work fine too... I have a 64Gb OTG card that was working brilliantly with it earlier, shame a friend wanted to borrow it cos I was gonna load it with stuff to do at work tonight...
Looks like Im going to have to pick up a 128gb sd card soon. Thanks for comfirming this since I was wondering the same thing for my Zenphone 2.
I'm running a Patriot 128GB microSDXC myself.
By the way, whats the best type of external microsdcard to use?
Do we need to be choosy in buying??

I always like a good ol' SanDisk
I'm just gonna add a little bit more here, You need a FAT32 formatted sd card for firmware updates if you are doing it manually and haven't rooted yet. The stock recovery won't recognise an exFAT formatted card (which is what most 128gb sd card are formatted) so when you put the update file on your card your card won't be recognised by the recovery.
Rooted with latest TWRP recognises card fine...
In anyone wants to know, I'm using a PNY 128GB card (http://www.amazon.com/gp/product/B00OP2P0ZO?psc=1&redirect=true&ref_=od_aui_detailpages00).
Stock everything. No issues with the ZF2 recognizing the card or accessing.

Seems like a lot are testifying that 128gb is working with their Zenfone 2. My question is will prolonged use of 128gb sd cards have any problem in the future?

Pretty sure you can't have any more info than what's currently available. The phone's only been available for a few months, that's as long as testing with 128GB exFAT or FAT32 will indicate stability for. Card size has no impact on a phone's microsd reader, just like sock size has no bearing on the size of a person's genitalia
FWIW I got a 128GB exFAT a week ago and haven't had any issues. If your phone has issues reading any card, it'll typically have trouble reading every card. Special exception is for devices that software/hardware don't support larger than 32gb, exFAT or Class UHS1 speed cards. Your Zenfone2 supports greater than 32gb, exFAT, and Class UHS1.

Our only choices for backups using ASUS backup are internal device or SD card. If we can only use up to 64GB, some backups might not work if they are larger than that (apps and data) or close to that in size.
With unlocked bootloader and root I have no problem accessing the exFAT 128gb sd card even while using TWRP recovery.
Not sure if the newer roms support exFAT or I have a magical Zenfone 2 but it did an OTA update with the OTA file on the sd card ... No renaming of the file was needed...
My model ZE551ML is not reading exFat 64GB card. Can it be formatted to FAT32 or should be replaced? My PC is only giving me exFAT file system when I try to format it!!!

Mine (I think) is formatted FAT32 and works fine. It's just you cannot have any individual files over 2GB in size.
EDIT: Never mind. I just checked via mount command and it is listed as "texfat". Guess I didn't reformat from when I bought the card.
exFat doesn't seem to be readable at all!! Can it be converted to FAT 32?? Thanks.

FAT32 is the recommended file system for SD and SDHC cards ... a 32gb SD card is an SDHC card.
exFAT is primarily for SDXC cards ... (i.e., greater than 32 GB).
Both FAT32 and exFAT are Microsoft designs.
I suspect your issue is directly related to LINUX and the inherent formatting of your internal storage where I presume you are downloading your videos/images to before moving them to your SD card.
If your videos/images individually are not exceeding 4 GB there is no need to go to exFAT on an SDHC card but because the LG G4 supports cards greater than 32gb, i.e., supports exFAT, you will be able to see them when moved to your card.

Yes i know. thats why i formatted to exFat, sometimes i need 4gb+ files.
I just directly download to SD card with phone.
Im thinking its about LG's software. deleting files is so slow (2gb files 10sec+) and not refreshing in gallery.
I was readed somewhere fat32 have (log daily feature) or something like that for changed files and accuracy files idk properly but exFat not have this maybe its about that.

Before coming to that conclusion ... i.e., thinking it's about LG's software, you would have to test out an SDXC card and see if you're having the same issue. Then you might be able to make a case to LG if everything else is set-up properly.

You're not using adoptable storage ... for the set-up of your sd card are you with android 6.0, Marshmallow? Needs to be set to portable I believe ... irrespective of what you've set in Opera.

Then borrow or purchase an ... SDXC card and see if the issue recurs when formatted as exFAT.
You could try re-formatting your card with a different program and see if it helps but It may be your phone is having trouble reconciling a 32gb card to exFAT.
