## Good to know
- Basically, it follows my LineageOS 18.1 changelogs.
4Hello all,
I uploaded the update for HavocOS. Now, we're using HavocOS 4.16.
The overall changelogs will be the same as the LineageOS 18.1 I wrote in this forum too.
Check the update, thanks.3Hello,
I uploaded the new version for HavocOS and LineageOS. Please visit my LineageOS thread to check the changes.
Thank you for the feedback. And that part, actually I feel like it doesn't work like you. I will remove that feature in the coming version.
To fix the SafetyNet without root, we need SELinux enforcing as far as I know. And this part is so hard for me yet
And every change is applied to the HavocOS. Those two ROMs share the same device tree.3I found a solution for the Netflix issue!
Before flashing LOS and HavocOS I had a modded version of stock installed. Possibly bootloader or other parts were not the latest version. So I flashed the last version of the stock ROM for my region via Odin and then reflashed TWRP, the Rom, gapps, Magisk as outlined above. Now Netflix is working without issues.
So for anyone else coming from a ROM that's not completely stock (or possibly also from an older stock ROM?) and running into issues with Netflix or other apps, this may be worth a shot. - Display/Touchscreen
