why does the Portrait mode for the rear camera zoom the zoom the photo being taken?? it is impossible to take good portraits due to this. ..
[Xiaomi Mi Mix 2S Guides, News, & Discussion] malimukk:
Its using the secondary camera for portrait pictures I guess. And since the secondary camera is not stabilised and not as good as the main one, you need really good lighting and a steady hand to take decent portrait pics.
[Xiaomi Mi Mix 2S Guides, News, & Discussion] billamin:
why is the secondary camera being used like this??? secondary camera should be for depth sensing right???is it by default for others too?? can it be changed??

60fps recording is not working in 8.9.13, although the option is still there. I wonder, do the devs test the rom in real device before releasing it?

Magisk 16.7 works on China 8.8.8 (not tried 16.0), flashed the magisk zip via TWRP (adb sideload, as TWRP does not support P yet).
[Xiaomi Mi Mix 2S Guides, News, & Discussion] mattman83:
Cheers I ended up giving it a shot. On 8.8.7 global I flashed via patched boot image, magisk is running and root is functioning, but not passing safetynet like I did before. Use magiskhide props config and I assume I need a newer fingerprint or something.

Don't want to jinx things but pogo, netflix etc still working regardless, google pay is failing as you'd imagine. I assumed the others still did cts checks tho.

[Xiaomi Mi Mix 2S Guides, News, & Discussion] zerodi:
How did you flash via patched boot image ? Was it by replacing the 9.0 boot.img with the 8.0 version from another rom ?

Im using xiaomi.eu 8.7.26 at the moment

Thanks
[Xiaomi Mi Mix 2S Guides, News, & Discussion] mattman83:
So before I installed P, I unzipped the 8.8.7 rom file on my phone, in magisk hit the install button, and then pick option to patch boot image (be aware that you need magisk set to beta channel in the settings first and update to 16.7, last stable does not support P). Just pick the file you unzipped. Once you've flashed P then fastboot flash the patched boot.

[Xiaomi Mi Mix 2S Guides, News, & Discussion] fmotta:
I suppose your is the XA European model.

Because on XE model Magisk always give a bootloop after and sideload.

Got news for you guys, this isn't Android Pie. It still has the Oreo Easter Egg. It may be a hybrid of sorts, but it is not true Pie.
[Xiaomi Mi Mix 2S Guides, News, & Discussion] Saiger:
i dont know what u have installed but i have the pie easter egg. i even posted a screenshot of it in the first post. abd if thats not enough go and check the target api of the os, spoiler its api 28 (pie)
[Xiaomi Mi Mix 2S Guides, News, & Discussion] jim262:
I installed the global rom from the link in the OP listed as Miui 10_8.8.7_9. I installed the latest TWRP, rooted it and took a look at all the apps and code. I had the Easter egg from Oreo. That wouldn't be in there if this was pure 100% pie. But some things were added like the dark theme in display which doesn't work.

---------- Post added at 11:50 PM ---------- Previous post was at 11:46 PM ----------

Having worked in IT for 30 years it easy to see this was probably a mixture of Oreo and some new Pie features.

[Xiaomi Mi Mix 2S Guides, News, & Discussion] Saiger:
i guess the global rom is even more different now than china (not surprising tbh). could you check what the target api of the global rom is?
[Xiaomi Mi Mix 2S Guides, News, & Discussion] jim262:
That is merely the image, you need to look at the code. I can replace and image with another image. It will look different, but that doesn't mean thats what it is. For example if I take an Oreo rom, throw on a Pie icon pack and theme, so that it looks like Pie, it doesn't mean I have Pie. I installed the OP's Global_8.8.7_9 and when it booted up, I installed the latest TWRP and rooted it Magisk 16.7 and saw that a lot of the code is indeed oreo code with Pie features added in. It is not pure Pie. The setup was pie, so is the dark theme in display, but that isn't working. This is definitely a Frankenstein rom that is an Oreo rom with some new Pie features.
[Xiaomi Mi Mix 2S Guides, News, & Discussion] pi4a7a:
Can anyone share themrmals and benchmarks on P ?
[Xiaomi Mi Mix 2S Guides, News, & Discussion] Saiger:
Ahh I thought the API level determens the majority of the roms base.

But you are absolutely right. MIUI was always a weird mix of Android versions. It's actually pretty neat that their marshmallow roms have pretty much all the features of Oreo and so on.
[Xiaomi Mi Mix 2S Guides, News, & Discussion] jim262:
If I understand the Xiaomi naming convention, the rom is listed as 8.8.7_9. If I am not mistaken, doesn't that mean the base is version 8 or Oreo, built on August (8th month), 7th day with underscore 9 flavors? If it were true 9 wouldn't say 9.8.7 instead?

If you update to the Beta Pie, the only way to revert back to stable MIUI 10 is to use Mi Flash. You need to have your phone unlocked.

If you use the updater to revert from PIE to stable MIUI it will result in bootloops.

No you can't use updater to go backwards afaik. Will need to miflash and probably wouldn't hurt to wipe phone and start clean.
