Here we would like to talk about the SD card format for Android from the perspective of the file system, answering two questions: “what format does SD card need to be for Android” and “how to format an SD card for Android”. Now follow MiniTool to explore this topic.
What Format Does SD Card for Android Need?
Android phones support the file systems including FAT32, ext3, ext4, and exFAT, but the last file system is not supported by some older Android phones.
Absolutely, whether the file system is supported by the Android device or not depends on the Android device software and hardware. To make sure which file system your Android device supports, you can go to the official website of your Android device or check its manual.
Here might be some new terms that you are familiar with, and let us explain them one by one for you.
What is file system?
The file system is a data structure that an operating system uses to keep track of all the files and locate them on the storage device. In other words, if there is no file system, it is impossible to tell where one data stops and where the next begins. The common file systems include NTFS, FAT16, FAT32, exFAT, and so on.
What is FAT32?
FAT32 is an important version of the FAT (File Allocation Table) file system, and it was introduced by Microsoft in 1996 for Windows 95 OSR1 / MS-DOS 7.1 users and was the primary file system for consumer Windows versions through Windows ME.
The introduction of FAT32 improves large hard drive performance because the file system supports basic drive size ranging from 2TB to 16TB (with 64KB clusters), which breaks the design limitations of its processors FAT12 and FAT16.
The maximum drive size and file size the FAT12 file system supports are 16MB using 4KB clusters or 32MB using 8KB ones, and the maximum drive size the FAT16 file system supports ranges from 2GB to 16GB, but the latter can only be feasible in Windows NT with 256KB clusters.
What is exFAT?
The exFAT file system can be used where NTFS is not a feasible solution (due to data-structure overhead), but a greater file-size limit than the standard FAT32 file system is required. -- en.wikipedia.org
The exFAT file system was launched by Microsoft in 2006, and its full name is Extensible File Allocation Table. The file system was optimized for flash memory storage devices like USB flash drives and SD cards and has been adopted by the SD Association as the default file system for SDXC cards over 32GB. Compared with FAT32, exFAT has large limits on file and drive sizes — it allows you to store files much larger than 4GB.

What are ext3 and ext4?
The “ext” part of ext3 and ext4 is the abbreviation of the word “extended”. The extended file system was introduced in 1992 as the first file system created specifically for the Linux kernel.
ext3 or third extended file system is a journaled file system and is the default file system for many popular Linux distributions. It is the successor to ext2, and the two extended file systems have a close relationship that the conversion between the two becomes straightforward (both forward to ext3 and backward to ext2).
According to Wikipedia, the size limits of the file system are what the following image shows.
The ext4 file system can be also called fourth extended file system and is the successor to ext3. Compared with ext3, ext4 shines in the larger size limits — ext4 can support a volume with the size up to 1 exbibyte (EiB, 1 EiB equal to 1048576 TiB) and single files with sizes up to 16 TiB.
Moreover, ext4 is backward-compatible with ext2 and ext3.
