The update, which is rolling out at snail's pace and on the whim of carriers who rather you buy a new phone than update your current phone, is currently available on only a handful of Galaxy S6 variants. Namely, it is only available for the G920F global variant running in certain regions.
Fed up with waiting for Samsung to update my variant, I downloaded the bloatware-free French firmware (via XDA), and applied the update using Odin 3.10.7 for Windows. The process was simple enough, though it does expose a huge flaw with Android and Samsung's terrible update policy (like why do we need to wait months for firmware updates for certain variants to arrive or be forced to flash our firmware manually).
Here's a very quick guide (insert disclaimer claiming no responsibilities for any screw ups that may or many not happen) on how to successfully flash your Samsung phone with the latest firmware without tripping Knox:
- Turn off your device
- Press and hold down the Volume Down and Home button, and then press the Power button until you see a disclaimer, then release all buttons
- Press the Volume Up button to engage the 'Download mode'
- Connect your device to your computer
- Open Odin
- On Odin, check AP, and select the .tar firmware file you've downloaded and extracted
- Wait for Odin to verify
- Then press Start
- Go and make a pot of tea
- Depending on how many apps you have installed, your phone would have booted into a fresh new firmware
- Alternatively, do a factory wipe for a fresh install
It is still early days, but the phone just feel faster (probably placebo but a nice feeling regardless) despite not doing a factory wipe and the ability toggle app permissions is a huge welcome. But best of all is the support for manual control of the camera's shutter speed and RAW output. The S6's camera is pretty decent - perhaps one of the best on a smartphone - so the ability to gain more control over the control element is massive.
