This version doesn't update preferences for european networks on my Mi 8, both SIMs info report LTE/TD-SCDMA/UMTS chinese preference instead of LTE-UMTS AUTO (PRL) or LTE/ WCDMA. There is no TD-SCDMA in Europe, and being it first in 3G priority makes it hopefully roam for it, possibly using battery. This is a similar problem that exists in Global ROM I believe, and after reboot it returns to default values.
"SIMs info report" where? Where are you reading this information?

Hi dev team
Is it possible to port shortcuts feature in poco launcher to miui launcher
Would be great if we have that feature on stock launcherView attachment 22698

Not possible.
 
Yeah, I wipe the data,dalvik and cache before installing. What could i have done wrong else ? I am trying it again and again but cant get it work :(
It is FORMAT, done from TWRP, you need to acknowledge the action by typing "yes".
This will re-format your storage, and it will remove the encryption from the original Chinese ROM, and then you need to download the xiaomi.eu ROM and flash it

Press 5 times on settings \ my device \ internal memory
Or
*#*#4636#*#*


The default mode in all miui releases when set to "LTE preferred" seems to be configured for China. This is causing additional battery drain and signal loss during lte>3g handover

The default setting used to be different in earlier miui versions (global / td-scdma)

This WILL NOT cause signal loss during handovers.

The handover target selections are controlled by the network, specifically the MME and RNC.

Also the cell selection and reselection process are also network defined.

I write samw before.

Black screen after unlock in redmi 5, it happen when i update 9.1.2, i want go back 9.1.1 but i can't find it :(
 
I finally got it working. I had to change my pc to flash the china stock rom with miflash and then i was able to flash twrp. I chose the 1217 and installed the rom after formatting the data, thanks to everyone. Hope i dont find a lots of bugs now :D

In the case of the MI8 it does appear otherwise. I guess there's a baseband issue that's amplified by the network mode setting.
I'm aware that the handover is largely controlled by the mobile provider.

I ran a little test today to find out if other devices handle it better and it does appear to be so. Mido battery drain with LTE/WCDMA and LTE/TD-SCDMA/UMTS was exactly the same.
But the cell signal history wasn't...

Redmi Note 4X, Xiaomi.eu 9.5, 70km Highway drive with Waze and internet music stream running, fixed display brightness. Same route in both tests, just opposite directions - hence me flipping 2nd signal history in the following screenshot:

I ran a similiar test on my MI 8 a week ago and there were massive differences in battery drain and signal history...like I said I think MI 8 has a baseband issue. Cell standby drain seems to be unusually high.

MiMix2 [6/128GB], Weekly ROM 9.1.3

Bug with ANT+ devices.

ANT+ Service closes unexpectedly during "Find Device".
All ANT+ Services installed and with all permissions.

I have Bug report, but cannot attach files for some reason "Choose File" button on the "attach files" page does nothing (F-Secure SAFE browser) or only allows camera images (default MIUI Browser), not zip files.

In your test for Redmond Note 4X I would caution against comparing the "out" and "back" routes, despite driving the same physical route.
During my work in RF & RAN Optimisation, I see many situations like this caused by incorrect neighbour definitions, particularly with UMTS and it's SIB11 list limitations, and the H/O priority settings in the neighbour definitions.

Also I do not know the source of the cell signal history data - I assume where there is "grey" bar, the phone had no signal at all? Could you confirm that with a "Network Signal Guru" trace file?

There may well be a fundamental issue with the baseband for the Mi8, as the only time the network search list should look to the basic phone settings is when the phone is initially powered up (after manufacturing or a full "clean" flash.

Yeah I'll try to run another Mi 8 test with some proper cell monitor / logging software when I have the time.

Regarding signal history in the Android battery stats:
The colors represent signal strength.

I am not expert, but better network signal = better battery life always. Perhaps is not that perceptible. You can try changing between options and check the signal strength (minor number better)

Ok let's assume we found the best option for our Network.
How can we save it because after reboot it reverts back to pre defined option.

Stronger signal does not necessarily mean better battery life - in many areas with "strong signal" there is often high interference (both uplink and downlink), which has many negative consequences for device battery usage.

This Rom + sphinx 2.3 kernel is awesome, the battery life is so good. I charged my Mi8 Thursday afternoon to 100%, now I am hat 60%. Almost no draining.
Thank you, this is the first time flashing the kernel, looks like it has a lot of good things on it. Perfect combo. Love it.

Network signal monitor doesn't work without root. :/

I could provide a netmonster cell log?

We can't.
There's mods that require root or we modify the system apk in Rom.
