    Here is my first update a little under 24 hours later with the China Mi 11 Ultra on ATT in the US.



    1. This is a freaking beast of a phone. Completely worth the hype.

    2. The China ROM is extremely usable. So much so I am considering using it full time. However, I did go ahead and start the 165 hour or whatever bootloader unlock process to unlock and flash .EU or Global if needed.

    3.Basically all google services work flawlessly. Google Assistant triggers via hot word, opens up whatever is needed, etc. YouTube, YouTube music, etc.

    4. Service with ATT has been shockingly good despite not having LTE band 66. ATT has no 5G in my market so I cannot speak to that. However, LTE has been fast. I live in a more rural part of the US than many of you could imagine, and I travel through some extremely rural areas. (I am talking driving past a field of 400 cows). I pull 50-150 mpbs download speed everywhere I check. While driving through that mega rural area I was on a phone call the whole time, and the quality was fine and did not drop at all.

    5. If you are new to MIUI you need to know a few things. Go into every app that you care about's settings. Enable auto start and turn off MiUI battery saver. Then go into the security app, settings button at the top right. Click boost speed. ADD EVERY APP you want notifications from, along with the steps I mentioned above. MIUI is like a splash of cold water on your face if you are not used to a Chinese OEM. However, once you LEARN to play by its rules, and tweak. Basically, all of your quirky problems can be resolved. Just give it some time. Google problems, look them up on reddit. Most likely there is a way to tweak MIUI to stop doing something annoying you don't want it to do (such as virus scanning new apps). Be prepared to spend a good bit of time de-chinafying your ROM. The western and eastern market have vastly different taste in how Android should function.

    6. The camera is amazing. Took some amazing photos of my kids. The shutter isn't quite as fast as my Pixel 4 xl, so there is some chance of motion blur. HOWEVER, its NOWHERE near as bad as Samsung's shutter lag and motion blur on moving objects. I would say with my s21 ultra and every Samsung before 3/5 photos of kids were unusable due to motion blur. On the Mi 11 Ultra is maybe 1/8-9 photos is a bit blurry if my kids are really moving.

    7. All my banking apps work without issue. Specifically American Express.


    8. It charges BLAZING fast. I went from 1% to fully charged in under an hour. Although I did not time it. The battery lasts a much longer time than the Global Mi 11 I tried a month ago. I have 2.5 hours of SOT today and still have 70% battery.


    Here are some issues I have run into within 24 hours. None of them are major, but I figured I would note them.

    1. I cannot get visual voicemail to work. Either through the Google Dialer app on Beta (Which literally works on every single phone on ATT that I have tried with) nor the ATT visual voicemail app. I am not giving up on this one as I think I can still fix it.

    2. Google Pay fired up without a hitch, let me add cards flawlessly. However, when I went to use it at the grocery store. The NFC would scan, the phone would say "leave network connected while paying"(or something similar) and then the terminal would say transaction failed. I did this a few times and it happened every time. I'm not ready to say it doesn't work but I was done holding up the line. I just paid with my physical card and moved on. I will update if I can fix it.

    3. Bluetooth behavior to my car, while making calls with audio output has been extremely buggy. It doesn't seem to matter if I toggle it from Bluetooth, to speaker to earpiece. It's like the audio gets lost. It doesn't happen every time either. It's just a buggy mess when it does. I'm wondering if it's some kind of output bug with my car and my Bluetooth Samsung watch and the phone doesn't know where to output the audio. Will update this with more troubleshooting.




    I will update this thread as I spend more time with the device. AMA.

    EDIT: Also to save some headaches. If you have a Samsung Watch. You need to change settings on all three apps. The wear app, the "watch(insert model) plug in app" and the samsung accessory app. Turn autostart on for all of them. Turn off battery optimization. Then go into security > Settings > Speed boost. Add all three to your speed boost. If you don't, every time you clear your recent apps the watch will disconnect.


    Edit 2: Gpay is now working thanks to a tip from user: jirka607. Switch default wallet to HCE.

    Edit 3: I've given up on visual voicemail. Just set missed calls to forward to Google Voice where I can check voicemail "visually" via the app.

    What apn settings are you using for At&t? You had to manually put them in? I have the chinese version also on at&t and my data seems slow at times...

    I have flipped back and forth between ATT phone and NEXTGENPHONE. I see no difference. If you live in a more populated area the lack of Band 66+30 may be hurting you. Both of those are used to help offload the main bands I believe. I made zero APN adjustments.

    Whereas in my area first EVERYONE has Verizon, so there is far fewer users on AT&T. Secondly those of who are on AT&T around here are geographically spread out as this is not a metro area.

    We do have large population centers, but even those are relatively small compared to major cities. Honestly If I can pull 10-30 mpbs while driving around town. I don't really care. That's enough to stream youtube and listen over bluetooth.


    For reference. I just pulled 59 mpbs download on standard LTE in a spot that with my pixel 4 xl would get ATT's fake 5G 5Ge and it would pull 150-200 mpbs in the same spot. So a definite hit, but completely usuable for any all task I could use it for.

    Awesome write up as I am considering using this phone as my daily driver if it is that good as I'm not really a fan of Samsung these days. Cant decide to get the Chinese version or wait for the global version but reading this and you are using AT&T as well it seems the Chinese version might be the way to go anyway. You have any issues setting up the phone or just pop in sim and go?

    Nope, literally just popped the sim in and boom. Service.

    For the google pay problem go to NFC setting and set to HCE Wallet
    Yeah I tinkered with those settings out in the parking lot, but I didn't really know what they meant, and I haven't tried it since. So I'll run by the coffee shop and give it a shot with a status update.



    Update: Google pay worked with this change. Thanks!

    Thanks for the reply, is there anyway you can send me a link or a copy of those apn settings? When I find them online and enter them, I save them and then they just disappear... Thanks!

    I'd like to add. This phone is the the first time wireless charging has ever made sense to me. I got the 80w Xiaomi charger on Trading Shenzhen.

    It's s complete game changer knowing you can just slap your phone down quickly and top off at anytime the same speed the wired charging would be.

    That doesn't work on China nor global.

    It's also bugged to hell on every other OEM including Samsung
    Samsung bugged? I have t really noticed. You can customize Samsung as much as you want. Default launcher bothers me though. It's crappy we need to wait a week and all the personalization goes to drain as it's better to set up from scratch on xiaomi eu. And the missing notifications...

    Question for you. I bought the global version of the Mi 11 Ultra. Am waiting for delivery. I also have the Samsung S21 Ultra Exynos version. I have not been impressed with the camera of the s21 ultra especially indoor pics. A lot of noise in indoor pics. Do you think Mi 11 Ultra has a better camera?

      Thanks for the info. Maybe I should just jump on the China model since I can get the 8GB model for cheaper...

      When you say de-Chinafying it, what are the initial changes you have done?

      Thanks for all your help and responses! This is very helpful.
      Basically you need to add the app drawer, because by default it's like iOS with all apps on screen. Otherwise swiping up brings a ton of chinese stuff up

      You need to disable the Xiaomi feed (app vault?) which is to the left like Google Feed is on Pixels, but it's a bunch of chinese stuff.

      You need to go to notifications and tell it not to "group unimportant notifications" because that literally just is the dumbest feature ever.

      You need to go into the mi app store, go to your installed apps, and uninstall like 30 Chinese Bloatware apps.

      You need to install Gboard because the Xiaomi english keyboard is weird

      You need to disable "Xiaomi secure keyboard" that remains after installing Gboard on password menus because it seems to affect autofill from password managers instead of having Gboard integrate directly with your password manager.


      You need to go to wallet and change it from Mi Wallet to HCE so Google Pay works.


      That's all I can spitball off the the top of my heads but that will go a long way.

      Xda Thread


      Are just a few. I can't seem to find the Nova statements but I've experienced this first hand and so have the others in those threads.

      On my S21 Ultra. As recently as early March. Swiping up on Nova to go home would cause a crash like animation where it looked like the launcher restarted. That's when I found out I'm not the only one by searching around online.

      The size and weight don't bother me. It's similar to any Samsung Ultra model or iphone max model.

      The camera bump actually makes a nice grip when you want one hand it and reach the middle of the phone.

      The EU ROM is supposed to be a more westernized version I suppose. However it's not an official ROM but a community project which does seem to be well supported.


      I actually used the Global Model from Xiaomi of the standard Mi 11 back in February and honestly my experience with the China model Ultra has basically been the same. Other than the intial de chinafying it
      The EU ROM although community based is recognised by Xiaomi and every beta weekly or stable is made using the latest weekly or stable Chinese ROM. I used it on my 10 Ultra and will flash on Thursday my 11 Ultra once bootloader is unlocked.

      Where did you order from? How long did it take from the time you placed your order until the time it delivered?

      Reason I'm asking is I placed my order with Giztop on the 9th and still haven't had any movement
      That’s not good to hear I was about to pull the trigger and order one from them but now I’m nervous and might go to tradingshenzen

      Very informative! Thanks a lot!
      It seems not much difference on China vs Global version in terms of usability.

      Based on your very detailed review, it seems no need to torture yourself waiting for global version :) and I think global version is more expensive which for me it does not make sense if Chinese ROM is running smoothly.


      I've had the phone for almost a month. I did end up flashing Xiaomi.EU Community ROM. It's a bit more polished for an english speaker. However If I had to keep using the Chinese ROM I'd be able to do so with no issues.

I have not been impressed with the camera of the s21 ultra especially indoor pics. A lot of noise in indoor pics. Do you think Mi 11 Ultra has a better camera?
      After using them both. I think the GN2 and the larger sensor on the Mi 11 Ultra gives it the win. I think the S21 has better ultra wide and tele photo. That's not to say the Mi 11 Ultra has bad ultra wide and telephoto though.

      The Mi 11 Ultra does very well on dim indoor photos compared to previous phones of mine like Pixel 4 XL, S21 Ultra, iPhone 11.


      I took the Mi 11 Ultra out to the park with family today and it was AMAZING.
