any problem with china set oneplus 9 flashed with global rom?

finally done my 9pro CN set to ColorOS 12  (-^〇^-)

fast respond than my 4 year ago phone. this my 1st 1+ phone, i cant comment OOS. i heard OOS alot bugs not slove yet, that why switched direct to COS12. 😃

Mine is also CN set, but being flashed by the shop to India ROM. Just wondering global ROM any different from the India ROM? Seem like OOS having a lot of fire from the owner, I also thinking just switch to Color OS instead since everyone said it can be installed with Google PlayStore.

Just want to know, since the CN set is original install with Color OS but flashed by the shop to Oxygen OS, this would mean I need to download what they call "Downgrade" package to switch the OOS to Color OS, is this the correct way?

After reading some review from YouTube, I guess to be at the safe side, I stick with OOS because too many "junk" apps exist in the Color OS, which I am lazy to find way to clean them off. Not only Google PlayStore need to install separately, but also something else which related to google contact sync also needed, Otherwise, the google contact will not be auto sync. I heavily depend on google services, so, better to be safe than sorry even i itchy hand want to try something new. The OOS really become a bit bored to my daily usage.

I think the package you downloaded might be the lower version that why the phone current firmware reject to install.

I don't dare to update to OOS 12 yet for now as heard too many complains. The local update setting missing could be the company want to merge the OOS into Color OS which is less flexible in the way how the firmware is updated. Anyhow, please post if you faced any issue in the OOS 12. I will wait to see want or not to update when OTA is available.

Btw, I don't see the oneplus 9 pro selection from the following website to download the official firmware. Or there is actually no oneplus 9 pro but only oneplus 9 selection?

In case anyone who has the Oneplus 9 Pro and updated to OOS 12 and having issue, the last resort will be factory reset.

which carrier youre using?

no need root for volte?

oh so this will be oneplus first phone to support volte without rooting
theres a sales coming up on 12.12 for op9 regular its 1.9k, slowpoke can get to buy ah?

Yes its very buggy and many sources say if u factory reset your phone now after updating u will have a better experience.

bugs i face

-keyboard disappear and reappear if notifications come in when replying in any apps when u are typing
-black screen of death, need to plug in charger to wake the screen. totally blank as in u long press power button u see a grey box pop out but no turn off or restart button.
-auto brightness is not working.
-volte and vowifi no option to enable it back
-boot up super slow
-sometimes have problem unlocking the phone smoothly, unlocked but still lag
-camera macro shift problem, shift into macro then back normal the back macro the normal again
-screen fps still choppy since last time till now
-detect some normal apps and activate Game Mode like MyDigi or some bill apps, when TAC come in cant see and no pop up notifications. i keep resend the tac over 3 times

what has improved
-gallery fast and snappy thanks to coloros
-vibration more power
-thats all

After too much complains, Oneplus withdraws the official OOS12 update. Why release something that is not stable yet?

You can... but must perform total wipe.

Or straightaway upgrade to Color OS 12.
Shouldn't be any issues.
Disappointing right? No matter how much a Oneplus fan I am, I can't help but express total disappointment with Oneplus now.

Your set is China set flashed to global rom by the phone seller rite..

Oos 11 and oos12 both also can run volte on maxis?
I see pixel 6 is a good phone, but no volte out of the box is ridiculous already huhu

Hmm
Your phone got wireless charging? Seems like oneplus 9 don't have wireless for China set
