suhide hides systemless SuperSU from various apps - including Android Pay (for now, anyway).
Unfortunately SuperSU did not work on the Note7 (Exynos) out-of-the-box. As its release has been delayed in my country, we've had to resort to remote debugging, which is slow and frustrating. But, thanks to the ever helpful Dr.Ketan and SeraphSephiroth we finally got it working.
I have just uploaded v0.52 of FlashFire to Google Play, and it should be available for updating within a few hours. In the meantime, you can grab the APK directly from my server (see links below).

With this release, FlashFire leaves Google's awkward BETA program, and is available through the Play store for everyone.
Let me just start off by noting that SuperSU v2.74, as well as the previous version 2.72, are fully compatible with Android N Preview 3. So if that is all the information you were looking for, there you have it.
This update brings nothing more or less than compatibility with Android N Preview 3.
Today's FlashFire update brings a major new feature and many smaller fixes and improvements.
This is a relatively minor update. Support for the patching ChromeOS-wrapped Android boot images has been added (Pixel C), some logcat and fsck issues were fixed in the SELinux policy, and some flags have been added to the ZIP installer.
The major new feature of today's FlashFire update is the ability to create backups that can be flashed back to the device with fastboot. This will allow you to restore your phone from your computer without booting Android or even a custom recovery. This is a new and experimental feature, and as such there are a number of ifs, buts, snags, and caveats.
