Using this since past 2 days. I am completely stock with locked bootloader, unrooted and stock recovery.
No issues till now. Feels good to be back to stock oxygen OS for a change from all these custom roms.
You installed it on a locked bootloader. So you factory reset the phone before updating. Or did you just flash and lose no data

I installed it on a unlocked bootloader. I was previously on Skydragon. Flashed stock OS in twrp. Lost all data in internal storage after reset.
I'm running rooted Skydragon OS with twrp and unlocked bootloader. Can I directly flash oos via twrp? Will there be any issues?
Does the stock recovery replace twrp after flashing oos?

Yes you can flash it over twrp on skydragon and yes it will replace twrp with stock recovery. But keep in mind you will also have to format your internal storage completely because it will give a decryption failed error.
So after you flash stock and when the phone boots up it will ask you to format the internal storage so backup everything if you want to go this way.

Do you know if it will be the same if you are not encrypted, and want to stay not encrypted? Is there a way to do that without formatting (maybe using the patched firmware or theone3os)?

Just installed it, the initial look seems good. The phone spent some time optimizing the apps but after that it seems smoother and much cooler looking.

It is not. You will have to factory reset/format data for getting OOS Pie. That is going to delete your data, Magisk and in the process, you may have to reflash TWRP also.

I'm on open beta 39 OnePlus 3 with twrp bluspark.
So can I download the update or the full ROM? I'm a little confused as to where it is on the forums.
Then do I just flash it in twrp (wipe first I know but should I wipe data as well?) While flashing does it tell you to wipe, format or do I do that all myself?
What are the s steps?

I'm happy to wipe everything as I want to clean up my device anyway.
Thank you so much for the help.

How's the performance and battery on Oxygen OS 9. 0.2?
Can you root it?
Does Google camera work?

Performance is good and smooth. Good battery life as well. I haven't rooted it yet, wanna keep it stock for the time being but I am sure it can be rooted. Yes Gcam works. I am using one of the stable Arnova based Gcam.
I wasn't able to root Oxygen OS oreo firmware that's why I was asking

Battery life is not as good as Oreo OOS. I have disabled OnePlus's advanced battery optimizations, you should know.
Performance on stock kernel is mostly fine with stutters in phone app mainly. But i think that's phone app's fault. Performance with the custom kernel I am using right now is great and the ROM feels smooth.
Yes, I am running it rooted with a custom kernel.
I haven't used Google camera as I hardly use my phone's camera. Maybe once a week.

How did you root it?
Which custom kernel are you on?
Also does the bootloader get locked after flashing oos?

Those are pretty basic questions actually. I assume you haven't rooted your phone in recent time?
I just flashed the magisk zip before first boot into system to keep twrp and one restart settled things and magisk is now working fine.
I am using mcd kernel build r27 but it has broken Hotspot functionality, which I don't care much about.
Why would the bootloader get locked after flashing OOS? You need to manually go into fastboot mode and manually enter some commands to lock/unlock bootloader. It can't be done via recovery afaik.
