Sharing my experience.

I bought OP12 China version that comes with ColorOS. I read that China model flashed with OxygenOS cannot be updated OTA. So I just give ColorOS a try.

I like  that I can uninstall almost every single app (except the essential ones like Phone, Messages, Photos, App Market, etc). I can add them back via Settings -> Apps -> Recover system apps.

I enabled Google Play Services, and Google Playstore gets installed automatically. I don't need to download separate APK. I replaced all app with Google Apps, and all works great. Even Work Profile works fine too. I don't have Android Auto supported player, so couldn't try, but I was able to install it, and it appears in Settings -> Connection & Sharing.

So far so good! Looks like I don't need OxygenOS, since it's just a toned-down version of ColorOS. For RM3.1K with charger and casing, it's very hard to justify for Malaysia set at RM4K++, with no charger.

Nice little review there on Color OS. 

But there are a few corrections that need to be made.

No1. Chinese models of the Oneplus 12 flashed to Oxygen OS can be updated OTA.

No2. Apparently Android Auto is not supported on the current version of ColorOS as per reported by users of the Oneplus 12 on Color OS. (This I have not tried myself as my set was flashed to Oxygen Os before being shiooed to me).
Yup. It totally makes no sense to pay Rm1K++ more for a Malaysian set which doesn't not even come with the VOCC charging brick out of the box.

Yes. If you are in the know how. 

Nice. If you follow all the steps correctly its not too hard no....?
Its the Chinese apps that we want to get rid off. Google apps and services is also one of main our priority.

nice review on colorOS

1 question anybody
if factory reset phone after flash to oxygenOS  the OS still oxygenOS right  cos ROM already flash?

Of course. You are already on Oxygen OS. After factory reset will still be on Oxygen OS.

If you want revert to Color OS you would have to flash back to Color OS.

My beloved 9pro suddenly got green line last night, been thinking of moving to iPhone or Pixel 9, but compare the price and specification, OnePlus 12 still the best bang of money! Price and everything it's the best.

Been researching on shopee for Oneplus 12, all almost around the same price and check the review from the buyer with picture there are few version of the hardware:

i see mainly on the review said that ROM is flashed to Global ROM (CPH2583) but on the box it's actually stated PJD110 (China version), my concern it's it's there any issue or different between CPH2593 & PJD110??? Hope some sifu can enlighten me on this.

Was using my 9Pro (LE2125) for few years on Digi, but i never get 5G works on phone, went to Digi store to activate it and all, 5G never works, so my another question it's will 5G works if i buy the PJD110 that flashed to global rom?

Hope sifu can help me with the above question before i made my purchase.

I got my 16GB+1TB at RM2865 earlier this month 

I'm able to get Lazada 15% voucher, cap at RM500.

Any notable improvement? or bugs noted?
