Part 9: Android 11 on K2001n – The "Fake Version" Trap

Here is the hard truth: Many K2001n units lie about Android 11. Manufacturers alter the build.prop file to show "Android 11" even though the kernel remains Android 6.0 (yes, really).

How to verify you have real Android 11:

Install Device Info HW from the Play Store.
Look at Android version (must be 11) and API level (must be 30).
Check the Linux kernel – if it is 3.10.54 or older, it is fake. Real Android 11 requires kernel 4.9 or higher, but K2001n rarely gets that – which is why official Android 11 is scarce.

If your "Android 11" update still shows kernel 3.x, you have a theme update, not an OS update. Do not pay for such files.
