I think you may want to check into #2 further. There is a problem with the GPS. One half of the satellites are not being received. In metro areas I am getting drifting going on from waze. The GPS beams are being reflected off of glass buildings coming back and cancelling out the position. I have even had cut outs because few US GPS sats have the L1/L5. It appears that someone said that it is a config problem that was fixed for the Mi9. Anyway, load in the Gpstest app in the play store and see if the euro sats are being received.

Are people still experiencing issues with the GPS? Anyone have a fix for that? It's the main reason I haven't moved over to this rom yet so I'm eagerly waiting.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] didi86:
Both, GPS and GLONASS are working. However, it's not picking up GALILEO, BDS or QZSS sats. Positioning may be a little less accurate without those, but it's still good enough for navigation. A fix has been suggested, but there hasn't been a new build since then.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Grazsrootz:
Ok thanks, I'm definitely keeping my eye out as I use GPS daily. It is a core feature and I really need it to work properly. Can't wait for it to be fixed

I'm unable to install GApps on top of this ROM. Can anybody help?

I've tried the OpenGapps Pico package (ARM64) as well as the Mind-The-Gapps package. But none could install. I've got the latest TWRP installed, btw...

Any help appreciated!

Also - is there a release date for the Offical LOS rom?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] didi86:
Have you seen this post?:

Also, don't ask for a release date or an official rom. At this point I consider us lucky if we get as much as another development build. The only developer doing major work on this rom got a new full time job and is working on Mi 9 for the moment:

Need help!

I'm trying to flash a custom ROM, and have tried this one (along with others). I have unlocked bootloader, and can flash custom recovery (using twrp).

I'm starting from miui 10.3.3.0

Boot to recovery, wipe everything (including trying format data), then install custom ROM (I've tried LoS + gapps stock and Pixel Experience). The flash seems to go OK, however the phone then gets stuck in a loop, it shows the bootloader screen, then reboots, and just does that!

I can successfully flash back to MIUI Global, and it boots fine, but every time I try to reflash to a custom ROM, back to bootloader loop again!

Any advice?

Edit:

by following this procedure:

https://xdaforums.com/showpost.php?p=79775968&postcount=193

I managed to get Lineage OS sort of working, although it feels buggy (probably from the dirty flash at the end).

I then updated the FW to 10.3.3 (via https://xdaforums.com/mi-mix-3/development/firmware-xiaomi-mi-mix-3-t3955361) - and have succesfully wiped and installed other custom ROMS, so am assuming you could then do a clean install of LoS.

[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] cshepa:
How do I get stock TWRP back on? I flashed the first build and replaced with the dtbo.img and first posted TWRP. Now I would like to reflash with the second build and stock TWRP.

I have now tried installing official TWRP recovery through the rooted TWRP app and also adb tools but when I boot to recovery afterwards I just get a mi logo blackscreen. (no recovery) and then it continues to boot to lineage.

So at the current time I have no recovery with the first rom that was posted. Not sure what to do. As stated I get no red flags from either TWRP flashing method attempted.

Would installing the second rom from the first one require adb back to back for both. Not sure what to do here, im guessing the problem is after flashing the dtbo.img

also fastboot is still working fine.

**********************edit***********************

A complete system reset solved my issues. I am now on the second rom with stock TWRP. There is still something weird with TWRP where after it appears it disappears and I have to hit up again. Maybe thats normal, unsure but its with TWRP and not the ROM. ROM is great! Sorry for the ramble.

If I understand correctly all the discussion, i have a global version of Mix3 on EU Rom. For flash this rom with no problems, i must to flash LR Team TWRP (for compatibility with GApps flash), last chinese vendor.img and only after flash this rom and GApps?

Try this

1.format data

2.flash latest EU firmware 9.5.9

3.let it boot

4.reboot to TWRP and wipe

5.flash 9.2.15 firmware (to have proximity sensor working) without rebooting flash Los and gapps

6.flash magisk if you like

7. Reboot

See if this helps
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] nuggeo:
Your pretty sure has no meaning over functionality. If we can't even open the camera from the slider or change to the front camera with the slider the rom is essentially pointless.

Also I personally really like the quick apps you get from the slider, if these were configurable it would be even sweeter. But for someone who needs the timer a lot it is a really fast way to get to it.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] colossus_r:
The slider is a xiaomi only thing. Aosp roms can't control it until xiaomi realize some new sources. I am sure cosmin and other devs will find a way to use it.

The priorities now are to have stable and fast roms for every day use. Don't forget that this is the first phone released with System As Root and it was really difficult to start the custom rom scene.

If the slider functionality it's important to you then you have to wait until the devs find a way to do it.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] invisiblewave:
Or just run MIUI until someone figures it out. I wish I could get rid of the FFC altogether and have a phone that's half the weight and half the width, even given a choice I'd leave the slider doing nothing.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] nuggeo:

Until recently I was using the 20190511-build and Android Auto was working perfectly. A few days ago, I dirty-flashed the 20190512 build, found that GApps stopped working. I then re-flashed GApps (I was and still am using Opengapps-pico, with Android Auto and associated apps installed from Google Play) and found that GApps were working again, but Android Auto only showed a white screen and eventually crashed with an ANR.

I then force-stopped Android Auto, Google and Google Maps, cleared both cache and storage of those apps and rebooted the phone with the same result: White screen, followed by ANR. Only after I completely uninstalled and reinstalled those 3 apps did Android Auto start working again. Any ideas as to why clearing cache and storage was not enough?

You use Android auto with the head unit of your car by plugging it in with a USB cable? I still have the flickering screen issue if I don't disable hardware overlays in developer options. You don't have that?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] didi86:
Yes, I'm using it with the USB connection and haven't noticed a flickering screen so far. I didn't disable anything in developer options either. I've had a white screen on the phone, followed by an ANR after dirty-flashing the current build over the 20190511 build (see my post above)

On the current (20190512) LineageOS-build I've only tested Android Auto once and only for a couple minutes to confirm it starts and that I can start a navigation. I'll try it on two half-hour rides on monday and let you know if I run into any issues then.

Until then: Which screen is flickering? The one on the phone or the one in the car? Does it happen immediately after you plug in the phone or only after a certain amount of time? Have you tried clearing cache and storage of the apps "Google", "Android Auto" and "Google Maps"? Were these apps included in your GApps-package and installed as system apps or installed via Google Play? If they were installed via Google Play, have you tried uninstalling and reinstalling them? If they were included in your GApps-package, have you tried re-flashing that? Which GApps-package are you using? Have you tried a more recent GApps build? Have you tried a different USB cable? Is it possible this issue only happens in some cars, but not in others? I'm using it with a fairly new (May 2018) VW Polo.
