Mi 9 miui eu vs miui global vs RevOS

Hi! i am very new to the xiaomi community. i have just bought a pre-owned xiaomi mi 9.
it was shipped to me via POST mail, when i opened the phone it is a xiaomi mi 9 chinese version. :crying:
i want to flash a new rom on it, and currently i am torn between the three roms.
i just want to know your opinions on these three roms in all aspects (battery life, performance, gaming etc...)
1. miui eu
2. global rom
3. RevOS
***i have seen the miui eu vs RevOS (here: https://forum.xda-developers.com/Mi-9/help/revolution-os-vs-xiaomi-eu-one-recommend-t3934804) but i want to know how they are versus each other and the global rom.
how are the updates on these roms (miui eu, miui global, and revos) delivered? do i need to reflash every time? or i can just update just like a regular stock miui chinese rom? (a.k.a. by going to the settings and clicking the update button there and rebooting)
thank you. :angel::angel:

how is miui eu compared to the global rom?
are there lags? or bugs? problems? can yu give me a short help please

Hello. xiaomi.eu rom is based on the beta or stable rom of china. she's stable for everyday use. it benefits from news before the global. the beta rom is translated into several languages ​​and updated every Friday. I use it now and I prefer it overall, it is much smoother. on the other hand it is necessary the bootloader to unlock.

that is for when i am flashing the rom newly,
i am asking about when i update.

I was on global rom and battery was very bad, but beem a week on revos its very clean amd good battery.
I recommend RevOs.

I have the Global EU (NOT xiaomi.eu) and i have good battery life (over night max battery drain of 5%), its buttery smooth and no bugs. Its official by Xiaomi but i heard updates are not as frequent as the China Global. Also since Global EU is stock you can just flash that over without unlocking bootloader if i am correct. The XiaoMiTool V2 somewhere here in the forum could be helpful for you if you want to stay stock and dont want to unlock your bootloader.
Edit: Also the Global EU has Widevine L1 which you need for Netflix HD. Dont know if the pther ROMs have that.

revolution os has the same ui with the miui ? how is the electronic image stabilization working on the rev os? how about other features that miui have, does the rev os also have?
i am looking at the miui eu because it has all the features that miui global have but better. so does rev os also have that?

I don't have any ads then. Seems the Global EU doesn't have all this Chinese preloaded apps. It has some xiaomi apps which can't be deleted, but otherwise I never had any problems. I was thinking of getting the xiaomi.eu so I can have notifications visible all the time and not just when they are incoming but that's all. I guess soon xiaomi will release an update for the global eu which will add this functionality back. Honestly this Rom is already so much superior than any other Phone I used and I think I can wait a couple of months for updates instead of having to deal with bugs and updates every two weeks with the xiaomi.eu

Camera quality stock ROM vs Xiaomi EU, Mi-Globe

I've searched the forum but didn't find anything about the significant difference between stock camera app from stock MIUI ROM and the Xiaomi camera app from other custom ROMs. I saw this difference with my older phones too (running MIUI or other LOS based ROMS), but never really used Xiaomi camera app because gCam was much better (mi5, mi5s, mi note 3).
But mi9's Xiaomi camera app is, in my opinion, way better that any gCam port i have used so far.
For example, now i am running mi-globe and the photos and videos are kinda disappointing, comparing them with the ones made in stock MIUI. There is a lot of noise, images aren't sharp at all, color reproduction is **** and exposure as well.
Had the same feeling on xiaomi eu rom as well.
So has anyone saw this difference? Or is it just me?
Just to be clear, I am referring to Xiaomi camera app.

planetera said:
Any problem you face on MIUI.eu, will also be on Mi-Globe because MiGlobe is based on Xiaomi.eu
Regarding your question, I think it's just placebo because miui.eu team doesn't touch the camera app at all.
If you are comparing EU to Global ROM, there might be some differences as they don't share the same base.
Chinese ROMs usually has different drivers than global so if this is the case here, yeah, you might get different results in on miui EU ROM and MiGlobe ROM

I dunno. Xiaomi.eu camera app is slightly different from stock rom.
Will try to do a comparison test with another mi9.

It is because of different camera libraries in china rom (base for xiaomi.eu and mi globe). Check this thread:

According to that thread, they do use different libraries. But there's where the thread ends.
These libraries are bundled in the APK file?
Would porting the global camera app have the same results on other ROMs than on the stock ROM?

I don' think so, drivers and libs are files located somewhere in system afaik.

Just did a quick comparison test using my mi9 running Mi-Globe and another mi9 running global stock. Same settings on both phones, AI and HDR turned off
Mi globe photos are less detailed and less sharp. And they are around 0.5 MB smaller in size.
So yeah, there is a quality difference.
If anyone is interested, I can share the photos.

Question Can anyone share their experiences of Xiaomi.eu ROM vs Global ROM?

I own the Mi 11 with CN ROM and have been using it in North America. I'm thinking of flashing a different ROM to see if it will be a better experience. Has anyone in my situation flashed both the Global ROM and Xiaomi.eu ROM and can give an opinion on which is better overall? I'd be interested in things like speed, battery life, Play services compatability etc.
Thanks in advance!

It basically boils down to privacy vs latest updates.
Xiaomi will phone home as much as you let it, I think the EU rom is supposed to fix that but updates take a little longer.

If you want more features use the Chinese EU ROM. Speed, battery etc will be the same.

Global is different to the Xiaomi EU one but many wrongly call the EU one global.
Xiaomi EU is based on the Chinese ROM.
Global is for outside China and has less features than Chinese and Xiaomi EU ROM.

I knew that the Global ROM (developed by Xiaomi) is meant for phones outside of China. I also understood that the Xiaomi.eu ROM is created by developers and is different (but based on) the Chinese stock ROM that shipped with the phone. I think you confused me by saying the "Chinese EU ROM" instead of "Xiaomi.eu" ROM which is what I usually see people say.
What I don't like about the Chinese stock ROM for Chinese users is that it doesn't seem to fully support all Google services and the implementation of Android 11 isn't complete (for example I don't see the Nearby Share feature).
What features does the Global ROM (created by Xiaomi for international users) lack that the Chinese ROM has? I think that as long as the Global ROM supports Google services fully I would be happy with it. If not then I guess I would flash the Xiaomi.eu ROM but it would be annoying to have to apply all updates manually.

Can't actually remember most of them but there was a few. A lot of the AI options like app pre loading etc
Xiaomi also confirmed the global Miui 12.5 update will be a "lite" version of the Chinese Miui so software will be more basic.
When I had the Mi 10 the EU version worked better than the global one with Google and notifications in general. Might of sorted that with next month's release.

Ok. Thanks for the info

I have CN ROM and had to tweak it like crazy to get rid of the China stuff and to get notifications to work. Turned off the battery saver for every app I needed notifications and enabled every option.
Now with EU ROM I didn't have to do anything like that, and have the google feed on the left. Everything is perfect with EU - well recommended.

Excuse me for jump in...I want to by Mi 11 Pro. I want Google Play, Google pay, banking aps, Netflix to work. Shell I stay on Chinese Rom or put Xiaomi.eu Rom? I am from Europe. Thanks!
Edit: Now I see it´s an old Topic :-/

I have already tried the latest stable MIUI14 from xiaomi.eu and it seemed quite alright
But I had one problem - which was rather annoying
I couldn't get my banking app to install properly. And I believe that is because the bootloader is unlocked. But my device was original CN, which I then flashed to xiaomi.eu (and locking the bootloader after that, is not recommended!)
So my question here is - if I install the Global ROM instead (which is xiaomi official, in contrary to the xiaomi.eu ROM), will I be able to lock the bootloader after flashing?

The EU ROM doesn't need to lock bootloader.

The EU ROM looks have a issue relate Google Backup.
Does anyone have the same issue?
New - Google Drive backup bug? Backup gone after reboot [updated]
[updated description below because it seems like backups dissappear after reboot] Not sure if this is from ROM or the Google Drive app. After a day or two my Google backup of my phone dissappears. Even though done successfully before and also shown in Google Drive, it dissappears after a day...
xiaomi.eu

One good reason to move to EU rom: it fixed stuff where China Rom doesn't!
For example, in China/Global ROM miui14.0.12 the AOD display will always turn itself off if it lay on a dark room for around 10 minutes. And turning off Bluetooth from android top down menu will turn off 24 hours only and not forever.
In Miui EU, this they fixed it by making it on always. Same goes to Bluetooth turning off when pressed from top drop down menu.
And many other translation jitter you can notice in China Rom if you were to restart your phone. For instance, calendar will show 1 second of Chinese before becoming english.

Question Can someone port the China weekly dev version 21.6.9 camera to EEA 12.5.3?

On the new China developer version 21.6.9, you can use the rear screen for videos. which is not yet enabled on the EEA rom. It is available also on the Xiaomi.eu rom, but it stil has a few hiccups. The EEA rom not only has the google services, which I need, but also seems a bit smoother. Does anyone know how that camera can be brought to the EEA rom?

It will get they're in some months, if you want it now flash the Eu ROM

Now, how do you think I found out one has this feature and the other doesn't? I flashed the various ROMs, but I also know that it may be some time before the EEA or Global versions see it. Heck, the Global rom hasn't even been upgraded to 12.5 yet.

EEA is on stable 12.5.3

I know that, but the CN dev rim has the video working on the rear display. Do you think I wanted to know if there is a port to an unstable rom? The Xiaomi.eu rom has it as well, but it is also based on the CN rom. Since the EEA rom may not get this feature for several months, I was hoping that someone may have ported that camera to the EEA rom, but I guess there aren't many devs here any more.

Nope unfortunately, things seem have changed from the old days of one plus 3 whereas community was much wider and much kore committed

Maybe it's also a less popular phone
Some people want one and can't get it, don't want or can't order from China or can only get one in eBay for €1500 etc which is unacceptable

Question Which is best MIUI variant for Xiaomi 11T Pro?

Hi Guys,
As our device is still pretty fresh for any custom rom development, can someone tell how many different versions of MIUI are present for our 11T Pro and what are the differences in the same and which one of them is good as daily driver considering camera, battery backup etc.?
This will help many ppl who want to flash different version than the one they are using right now... Thanks in advance!
Cheers!

I'd say the best is to take the official ROM and then debloat it to your liking.

I flesh couple days ago XIaomi EU rom, its much beter, no debloat , also the more importent thing is that the battery is batter.. I also debloat couple thing :

Had been using Stock 13.0.1 INDIA ROM since purchase and noticed quite lag with that so switched yesterday to xiaomi.eu 13.0.3.
There's definitely quite a bit of Performance Improvement.
Rest it's quite early to comment on.

Global V12.5.10.0.RKDMIXM or V13.0.3.0.SKDMIXM.
All custom are based on the Global version.
But i use Xiaomi eu rom V13.0.3.0.SKDMIXM
