Android ext4 support

Does android support ext4 for external sd cards. 64GB or 128 GB SD Cards come pre formatted with exfat file system. ext4 is much better and reliable file system then exfat. Android being based on linux should actually give push to linux based file systems isn't it?

So any sd card received with exfat filesystem can be reformatted to ext4. But will it work on 6.0 ?

I love linux. It is also my bread and buttet. Would love to use ext4 ?

Also by default when android formats the sd card which file system it formats to.

Any inputs ?

Re: Android ext4 support

No, ext4 is not supported. If you make that card internal (adopted storage) it is formatted as ext4. Even CM users that have formatted external card as ext4 can only work with card as root - Android may be Linux, but not 100% in some areas like permissions. 



exFAT & FAT32  gives you cross platform support (plugging phone into a computer) that you can't get with ext4. And the non-journaled systems are faster then ext4. 



I think the card is formatted as exFAT, but it could be FAT32 - I haven't checked in a while, and since i don't have 4GB+ files, I don't worry to much about it.

Re: Android ext4 support

Since I am using linux as my Desktop OS for souls like me cros-compatibility is not an issue. Feel may be in future adnroid version google will think over these lines and include ext4 support (some linux file system). Due to is journal file corruption is less and recovery chances more. That does not hold good for exFAT. Performance wise may be a little hit for ext4 but that may be negligible.



So as of now Microsoft rulez (exFAT & FAT32 :-) ) as far as file system support is concerned in android.

Re: Android ext4 support

Microsoft has a history of using leverage from patents related to android acquired through development on their end, mergers and purchases to extort manufacturers of android devices using these patents and force them to pay Microsoft for the privledge of installing android on the devices they manufacture, something that has earned microsoft more money than their products.

 

These acquired patents can also allow microsoft to do the same to android developers or demand that changes be made to the android operating system in areas affected by the patents they acquired.

 

SD micro cards often get lost and wear out, many of them are sold as a result.

 

Microsoft created the exfat file format, every time it is the default on a storage device microsoft gets money.

 

 

 

Permissions are specifically set in android to prevent android from accessing ext4 and NTFS format on external devices despite their vast superiority to exfat.

 

 

I doubt that this is a coincidence.
