As the title suggests, is it possible on Android N (7.0/7.1)?
I Googled around but all solution suggests that I format /data. And if I keep using the stock ROM without flashing Forced Encryption Disabler it'll be encrypted again. So I wonder if it's possible to manually decrypt /data.
I'm using OnePlus 5, whose stock system is very similar to AOSP.
