To discover the introduction of exFAT (Extensible File Allocation Table) support was Mishaal Rahman, who in the transition from Android 12L to Android 13 Beta noticed this welcome change on his Google Pixel 6 Pro.
Probably many users who own smartphones not from Google will have already taken advantage of the exFAT support and this is possible as the relative manufacturers have paid Microsoft (the company which created this technology in 2006) the rights to do in so that their devices can work with the wide range of accessories formatted in exFAT (Samsung is one of the OEMs who have decided to go this route).
In 2019 Microsoft made exFAT public and encouraged its integration into Linux and the community that revolves around this OS has started working on that goal: Samsung's exFAT driver has been modified and has been chosen to be included in Linux 5.7 .
ExFAT support is available for Android versions based on Linux kernel 5.10 (or later) but, although Android 12L is based on kernel 5.10.81-android12-9, it seems that for Google Pixel smartphones it is necessary to wait for Android 13 to be able to benefit from this functionality, because only with this release the strings necessary for the integration have been introduced in the code.
