I'd like to use ext4 on my SD card, or anything besides fat32 really. Something which supports files > 4GB in size.
Unfortunately, unlike it apparently was back in the day, now ext4 and even exfat-formatted SD cards are met with a message like "filesystem missing or not supported, click 'okay' to format", which when clicked, causes android to happily reinstate a fat32 filesystem.
Is there any way around this on an unrooted system?
Or am I stuck?
