As far as I know, no. Same for vice versa.

Network signal guru on play store. Needs root works on miui 11.

Xiaomi's/MIUI's Network Band Prioritization

Hello guys,
I'm using Mi9T Pro with Stock EU rom MIUI 12 version 12.0.4
I have this issue with Xiaomi regarding how the system handles prioritization of Network Band when it comes to using Mobile Data connection.
We know that we have options to prefer 4G, 3G or 2G. But it doesn't define which specific band. Like for example, 4G can be 4G/LTE or 4G+/LTE+. These 2 networks seem to be the same but these actually have different network bands
The question is how does Xiaomi system prioritize which band to select?
Does it prefer the one with higher signal or the one that pings better.
I have this question because as I have experienced, Xiaomi system seem to prefer the one with better signal regardless if it can't even pull any data. In short, it will keep connecting to a network with a better signal strength even if you won't get any internet connection out of it.
I've been noticing this when I set my phone to 4G preferred in my location. When signal indicator turns to 4G/LTE. It may seem to show you that you're connected to the internet but you can't really browse anything because there's actually no data for that band. But when it turns to 4G+, that's when I really get to connect to the internet.
And the biggest problem is that the system prefers to connect to the 4G band. That's why I'd prefer using 3G network because I have a more stable 3G+ signal here.
Another thing that's really disappointing is that my other phone OnePlus 5T handles this well. We share the same APN.
Sadly there's no band selection in *#*#4636#*#*
It would be glad if anyone could provide a better solution to this.
Thank you!

4+ g usually means (specially on Xiaomi phones) LTE Advanced Carrier Aggregation where no other/different bands are used but instead the phone is in parallel attached to more than one 4g band. As such, it increases the speed (and maybe, in your case provides a fail-over?!):
https://www.gizbot.com/mobile/featu...ifference-between-4g-4g-explained-053769.html
However, there is another question why (on that place) you have strong 4g signal with no Internet, so that when your phone switches to CA and in parallel attaches to another 4g band (maybe with a weaker signal) it obtains Internet connection over that second band
At least to better understand on which band (at which place and which base station) you have a 4g signal but with no Internet connection, install an app like Network Cell Info Lite, LTE Discovery, Net Monitor Lite). I think with Net Monster (all apps are on Playstore) you can even see on the map where is the base station you are attached to
If your phone is rooted, you could use Network Signal Guru that will show you, in case of 4+g all bands you are aggregated to with their signal strengths, base stations locations, etc (apps above would always show just one, primary band):

Ohhh thank you for this explanation.... Someone actually mentioned aggregation to me also. This helps make me clear up how Xiaomi does this and that. Does this mean force selection of network band won't work on Xiaomi devices?

I'm pretty sure that with MIUI 11 there was an option to disable/enable 4+, but on MIUI 12 (12.0.2 QFJEUXM) there is no more that option
I don't know of other options (except to prefer 4, 3 or 2 g), specially about selecting bands
choose band mode

Download activity launcher (play store), run it
Search band mode ===> Set radio band mode
Choose band mode you need

4G Suddenly became useless

Hello,
I am now having issue with my K20 Pro. I'm using 12.0.5 xiaomi eu
Not certain but possibly started after I upgraded to MIUI 12.
Issue is that the mobile data never works when signal is 4G/LTE.
Internet only works if you find a stable 4G+/LTE+ signal. The system would tend to constantly switch between 4G and 4G+.
Another option is to use 3G/H+ Preferred option. H+ works fine but as we all know this is the older network which means slower but decent data
I have read some solutions to delete and reset your APN. But it never works either. Also compared the network behavior between other phone like Oneplus 5T and it doesn't have the issue even using the same network and same location.
I'm not sure if this has been raised to Xiaomi directly. But I'm hoping there's a fix for this.
Thank you!!

I dont know if its exactly the same issue I had , but I give you my solution , it might solve your problem as well :
1. download Activity Launcher from the playstore.
2. Open it and search "miuiBand"
3. Choose the network LTE band of your Operator(look it up in google) for example LTE B3 (if you use only 4G , look at LTE and not LTE Preffered)
4. Toggle Selection ON (Top).
Hope this solves your issue as it did mine.

I have this. However, I can't understand why it suddenly changes reverts from time to time. Do you always take a look at it whenever connecting to Mobile Data?
As I also check in Network Cell Info Lite, phone still connects to the band causing the problem (Band 21)

When you get low coverage or restart the phone or get out of plane mode , your network settings go back to default (band will be chosen automatically), but forcing the prefered network type ,you will prevent this from happening (you will only have to worry about restarts /phone / modem).
Making the choice permanent IS possible with root (Check this Link : https://forum.xda-developers.com/ge...ific-network-bands-snapdragon-t3744243/amp/).

Btw, I cannot get Network Signal Guru to work with Magisk v21.1 anymore
Mi 9T (not Pro), tried with EEA stock MIUI 12.0.3 and Xiaomi.eu stable 12.0.6.
Last time it worked for me on EEA 12.0.2 with Magisk v21.0
I tried now that Samsung Band Selection app., it complains that hidden activity is not found (on my Xiaomi.eu 12.0.6) and it cannot open band selection options
But I don't have a problem with bands, just curious to tesr the things?
Bought a Xiaomi Redmi note 9s last month for Christmas for myself.
It had MIUI 12.0.2 on it by default.
Played around with it for a whole month and everything was working perfectly...4g LTE included.
I don't have internet at home so I use my phone has a hotspot.
Average download speed was 60 megabits per second.
... Until I upgraded to 12.0.3, I then lost LTE and only connected using H+
So beware before upgrading because I have not found the solution yet other than flash with pixel experience ROM.
Edit :
Changing Network detection from automatic to manual fixed it !
My Redmi notes "global" phones 4 & 5 had to flash new ROM to unlock bands.
Hope this helps
I realised that this issue is most likely due to baseband limitation with our Network provider. Given that I'm using a China Variant, the basebands my phone is lacking needed basebands here in the Philippines. What I'm looking for now is a QPST guide for SD855 to activate at least base band 20. I can't find any that has enabled it thru QPST yet.

Question Says 5g at the bars, multiple apps/speed test prove otherwise

Anyone who owns the Chinese version of the mi 11 ultra can test it out?
I got 5g enabled in the settings, confirmed selected in the dialer menu *#*#4636#*#* top bars say 5G and an HD symbol on its left which I confirmed is Vo-lte...
Issue is it's not really 5g but LTE or 4g, how I came to this conclusion was by running various apps/ simultaneous 5g speed tests on both this phone and an older Huawei phone I got..
Mi 11 ultra caps at 140+- dl speeds
Huawei caps at 500+- dl speeds
Provider runs 5g on band n78 which is supported by both phones..
Can running the Eu ROM fix this issue for me?
https://forum.xda-developers.com/t/...-xiaomi-mi-11-pro-ultra.4260617/post-84978259 Happen to me in xiaomi.eu STABLE. In China ROM probably it's a standard fake 5G icon, when connected to 4G/LTE network..

Thanks for forwarding me there, guess all I can do is try it out and hope for the best otherwise a 12gb/512 is up for sale
n78 is 3.5 GHz 5G band (is wiiide band, is not a 600hz band lmao) Your phone preferred to stay connected to 5G bands more than 4G bands.
Try to switch to 4G network preferred
And check it out your actual speed on 4G
(Huawei supports more bands than xiaomi...due to different processor which is Kirin)

Google Pixel 5 - Suppress all bands beside 5G and Connecting with QXDM

Hello Friends,
Wondering if anyone have any procedure or tried to unlock / root Google Pixel 5 to connect with Qualcomm QXDM to suppress all frequency bands beside 5G .. ie only like to setup that phone in 5G SA mode.... Thank you in advance.....
PS: This is just for some lab testing ...... and i have purchased an unlocked phone and it is not attach to any carrier.....
Network Signal Guru I think this app has an option to choose which bands to enable/disable.
Somewhere in the settings.

Question Mi 11 ultra no 5G cellular network [ stock global ]

Hello everyone,
I've just upgrade my plan to have 5G support, but the phone does't pick it up ( the carrier says it's ok )..
I also searched manually for networks and I find every network even from other provider but NOT a single one with 5G.
obviously I am in a 5G area, center of Milan, and sim slot 1 ( but I recall that was dual 5G, no? )
It's a bug, broken or I played with some setting disabling 5G?
thanks
EDIT: SEEMS LIKE THAT switching preferred types, airplane mode, while outdoor made the phone to connect t o a 5G antenna...
funny note, it's slower that 3g: 5.69mps/0.59mbps
Might need to enable it

you mean preferred network type? always been in 5G
Try to reset apn configuration and all kind of connection, then switch off the phone for 1 minute and reswitch it on

If you have the chinese model (not EU or global) you might have some 5G band limitations, and it's also to be taken into consideration which bands your operator is using in your area.
