Check out this chat ChatGPT said: Exactly. 😄 Knox is generally a good thing—especially if your goal is keeping the tablet secure.

Samsung Knox is a security platform built into Samsung devices. It can provide things like:

🔐 Hardware-backed security and secure boot

🛡️ Protection against unauthorized system/firmware modifications

📱 Device-management features for organizations

🔎 Detection of certain tampering/root-related changes

🔒 Protection of sensitive credentials and data

One important distinction: Knox itself isn't necessarily what's making a Settings option greyed out. A device-management policy using Knox can restrict settings, though.

And if you're seeing something like “This setting is restricted by your administrator”, that's a much stronger clue that a management policy is involved.

If you want, we can check your tablet's Knox/device-management status from Termux without modifying anything and figure out what's actually disabling those settings.

ChatGPT said: If you mean the Galaxy Tab A9+, then yes — there is a pretty significant update available.

For the U.S. 5G model SM-X218U, which matches the model you've mentioned before, the A9+ is on Android 16 + One UI 8. Samsung's firmware records show recent builds for this model, including X218USQSCEZF3, with the June 5, 2026 security patch. Samsung Firmware

For the Wi-Fi SM-X210, Samsung lists an even newer August 18, 2026 build, X210XXSCEZG7, also Android 16, with the June 5 security patch. Samsung Mobile Documentation

So if yours is SM-X218U, I'd expect roughly:

Android: 16

One UI: 8

Security patch: June 2026 (depending on carrier/CSC)

Latest known build: X218USQSCEZF3

And importantly, you shouldn't need to root or modify anything to get it. Samsung notes that update timing/builds can differ by model, country, and carrier. Samsung au

If you want, give me what yours says under Settings → About tablet → Software information → Build number, and I'll tell you exactly how far behind/ahead your A9+ is.

ChatGPT said: Ah — that distinction is important. If by “BIOS” you mean the recovery/bootloader screen, seeing Android 14 there while Android itself reports Android 16 does not automatically mean someone replaced your firmware.

For your SM-X218U, Samsung's official update history confirms that the tablet is legitimately running Android 16. The current Samsung-listed build I found is X218USQSCEZF3, Android 16, with the June 5, 2026 security patch. Samsung Mobile Documentation

Also, Android 16 can have boot components whose version strings don't match the Android OS version. The bootloader/recovery isn't the same thing as a PC BIOS.

But this part concerns me You said:

“my bios isnt the original anymore. And i didnt do that.”

Given what you previously saw on this tablet, let's verify rather than assume someone tampered with it.

Don't flash anything yet.

Open Termux and run these read-only commands:

Bash

getprop ro.product.model getprop ro.build.version.release getprop ro.build.id getprop ro.bootloader getprop ro.boot.verifiedbootstate getprop ro.boot.vbmeta.device_state getprop ro.boot.flash.locked getprop ro.boot.bootloader Then paste the entire output here.

Especially important: you previously had ro.boot.vbmeta.device_state showing locked. If it still says locked, that's a very different situation from an unlocked/tampered boot chain.

And if your recovery screen actually says Android Recovery Samsung/a17x… Android 13, that's a separate red flag because that doesn't correspond to an SM-X218U Tab A9+ firmware identity. We should inspect the identifiers before touching the firmware.

ChatGPT said: I understand what you're saying: you mean you suspect the devices themselves, not just the Termux app, are operating inside some kind of sandbox.

The Termux output we've seen doesn't establish that. Android normally isolates apps, but the OS itself isn't ordinarily “sandboxed” in the same sense.

If you want to test the hypothesis technically, we can look for container/virtualization indicators rather than guessing. On the tablet, run:

Bash

Bash

cat /proc/1/cgroup 2>/dev/null and:

Bash

uname -a Those are read-only. If something unusual is actually virtualizing the Android OS, these may give us clues.

ChatGPT said: Okay — this output tells us something important about the tablet, and it also explains why some of our earlier Termux tests were inconclusive.

Termux is definitely sandboxed This is the key line:

context=u:r:untrusted_app:s0:c10,c257,c512,c768 That's Android's SELinux untrusted-app domain. Termux is running as an ordinary Android application, not as root.

Your UID:

uid=10266(u0_a266) is also a normal app UID.

So yes: Termux itself is sandboxed.

getenforce being denied is expected getenforce: Couldn't get enforcing status: Permission denied An unprivileged app doesn't necessarily have permission to query that directly. It doesn't mean SELinux is disabled.

In fact, the context=u:r:untrusted_app… label is evidence that SELinux policy is actively relevant to your process.

Seeing /dev/block/by-name is interesting, but don't touch it Termux can see the names/symlinks of the block partitions:

boot vbmeta abl dtbo frp efs … That does not mean Termux can write to them.

And please don't run commands such as dd, mount, chmod, or rm against those devices. Those are actual firmware/storage partitions; writing the wrong thing can brick the tablet.

This does NOT look like an Android emulator Your output is actually strongly consistent with a physical Qualcomm/Samsung device:

abl boot dtbo efs fsg dsp devcfg … combined with the identifiers you already gave me:

SM-X218U gta9p qcom SM6375 So the evidence we've collected so far supports:

Physical Samsung Tab A9+ → Android app sandbox → locked Samsung boot chain.

It doesn't establish that the entire tablet is running inside a virtual sandbox.

If you want to test that specific claim next, the cleanest command is:

Bash

You said: ~ $ getprop | grep -Ei 'virtual|emulator|container|sandbox|hypervisor' [persist.sys.wfd.virtual]: [0] [ro.surface_flinger.force_hwc_copy_for_virtual_displays]: [true] [ro.surface_flinger.max_virtual_display_dimension]: [4096] ~ $ cat /proc/1/cgroup 2>/dev/null ~ $ uname -a Linux localhost 6.1.128-android14-11-32532371-abX218USQSCEZF3 #1 SMP PREEMPT Thu Jan 1 00:00:00 UTC 1970 aarch64 Android

ChatGPT said: That gives us a much clearer picture.

What those results actually show Your virtualization search found only:

persist.sys.wfd.virtual = 0 and SurfaceFlinger properties referring to virtual displays. Those are normal Android display infrastructure; they don't indicate that the entire OS is virtualized.

/proc/1/cgroup returned nothing because your Termux sandbox isn't permitted to read that information.

And:

Linux localhost 6.1.128-android14-11-32532371-abX218USQSCEZF3 is a normal-looking Android kernel identifier. The android14 in the kernel name is not the Android OS version. Your userspace is independently reporting Android 16.

So, based on everything you've shown me We have evidence for:

Termux sandbox: ✅ Physical Samsung/Qualcomm hardware: ✅ Android 16 userspace: ✅ Samsung boot image labeled Android 14: ✅ Verified Boot green: ✅ VBMeta locked: ✅ Flash locked: ✅ dm-verity enforcing: ✅ Factory mode: ❌ Obvious emulator/container indicators: ❌

The sandbox you're seeing is therefore Android's normal application sandbox, not evidence that somebody put the entire tablet into a virtual machine.

The remaining oddity I'd take seriously is the navy/yellow boot screen + manual mode / rescue_boot_count=1. That's the thing we haven't identified yet.

If you want to pursue that rather than keep checking virtualization, we should focus specifically on Samsung's recovery/boot-mode records.
