[Nexus 7 Android Development] Codster314:
Awesome! Ha, yea I still had the old ROM file from last I tested, it was 2017-07. :P But yea I just clean installed the latest version. Some Notes:

SELinux: Is indeed set to Enforcing. However it does not show up in About > Tablet Info (Under Build Number). Like it does on the UA Build. In HWInfo, it does indeed show SELinux is set to Enforcing though. It's nice having this in the About section, not too sure if it can be Added Easily.

SafeyNet: It does indeed pass right out of the box. No root or magisk needed. Just passes all the test.

DeviceCertification: Google Play Store Device Certification also passes (under Play Store > Settings > About). Passes right out of the box.

The above shows that you will be able to install all the apps you want from the PlayStore (Like Netflix,FEH,etc), even without root. Also most Apps should run out of the box.

However, FireEmblemHeros (FEH) does not work. Some apps use SafetyNet AND their own "root/gamecheat" checker. So when you open up FEH on this ROM (Clean Install, nothing else), it will load up, and then just crash. This is usually what happens if the App's Checker doesn't pass. I didn't test other apps, but I suspect other apps which check for Root inside the app will also not work on this ROM (Google Pay, Pokemon Go, Banking Apps, etc).

However, I did install Ziyan's UA Build (Clean Install) and tested FEH, which opened just fine (passed the app's internal checker). Since this ROM passes all the checks (in the list above), I suspect it'll be very difficult to see how the App is determining it's not an Official ROM. However, since Ziyan's UA build does fool the App, I assume there has to be something done (or not done) in this AOSP ROM that is making FEH (and prob those other "secure" apps) from detecting. Maybe the kernel doesn't block/approve the "Bootloader Unlocked" checks? Or it sees some binary or something in the FS it doesn't like. You might can change the Kernel, which may make the app run, but then you loose all those awesome performance tweeks done in this rom! Does the kernel report bootloader as locked (even if it's not?)... Anyway, I suspect Magisk Hide will run the App fine.

I did include a bugreport of the FEH crash, but as I said, I suspect it'll be very difficult to see why it's crashing. The app is Fire Emblem Heroes (com.nintendo.zaba).

This ROM: This rom bugreport link

Ziyan's UA ROM: UA's rom, where app opens fine, non-bugreport link after opening app.

Some more notes though about this rom... It is much more stable and much faster than the Ziyan's UA ROM. Performance wise, it was great, compared to the UA build... Very impressive. Also, the UA ROM randomly crashed twice (it does that) while testing the apps. This rom didn't crash once. Also the UA "pink picture" background comes back randomly, even after changing it to solid black. However if you want to run some "Secure" apps, you will have to Root/Magisk Hide them I suspect.

You should maybe mention in the first post, that SELinux:Enforcing, SaftyNet:Pass, Play: DeviceCertificated All Pass. Some people do look for this info while installing a ROM and this rom has them all.

Thanks for you time! And thanks for the Great Rom!
