Hi,
I'm new in MI8 community ? (just living leeco lepro3 ). I've strange switchs between 4G to H+.
I explain ?. Previously, at home, I was all the time in 4G with my PRO3. But now, my MI8 switchs time to time and during the switch I loss the connection. Nevertheless, my device receives full signal in 4G and it stays connected on the same BTS.
If I set it in plane mode ON and after OFF...back to 4G for a short time...
I'm on miui10 and on Sosh (orange) french network.
Tks for your help
Hey !
I'm also french and i'm experiencing that kind of H+ switches, as you I had 4g in these areas before with my oneplus 3 with Bouygues Telecom ISP and now i can't even connect to the internet, must be the antennas...
I can connect to 4G but something doesn't work fine...I can't stay connected. The level of the signal increase and dicrease strangly.
I'm a little bit disapointed :crying:
Because each phone have different bands and if your phone doesn't have the right band for your area cell tower then it'll keep changing back to the most stable connection it can do.
Sure, I know that. But I leave in campaigne with only one BTS. So I'm always connected to the same antenna.
And if it was an issue with the frequency band (lepro3 has the same), switching OFF/ON, airplane mode should not fix my issue.
I've tested with Mate 20, and i'm always 4G in full power received !
Nobody else has the same issue ??
I have the same issue, 4g and H+ are switching all the time. Sometimes it keeps switching several times in a minute on a fixed location.
I am in Croatia, operator is A1, Mi8 Global model.
very well it seems like it's not an isolated bug. can we trace this kind of problem to xiaomi and if so by which channel?
Hi, i'm still facing time to time the issue. No fix planned? I'm not alone.
Zero promises here but you can try forcing the network mode to LTE/UMTS auto (PRL) and check if it makes a difference.
To Change 2G to 3G 4G LTE only network mode in Android Phone via USSD code, take the following steps:
Dial *#*#4636#*#* OR ##626* OR ##786# in your phone
Select Phone Information
If you have Dual SIM Select the Slot (SIM) you want change settings for
Scroll Down and select the Option Under “Set preferred network type”

Also works by pressing 5 x times on settings \ my device \ total storage
Thks but It's not a good solution. I won't force network type choice.

If you flash 9.1.17 Xiaomi.EU they have updated Network Switching handover to European UMTS, instead of default chinese TD-CMDA to WCDMA as Stoffl_ says.
I had the same problem as you say of switching from LTE to H+ because of this. Either change it manually after boot or unlock the bootloader and flash another rom. Until they fix it in global, if they do.

You have use it and fix the problem?
Just ****ing change the network mode ffs

it depends on what you consider 4g? are you talking about LTE or are you talking about HSDPA/HSPAP? if its LTE it should show up as LTE, but depending on where your located and which HTC one you bought you might not have the bands. if your company has HSDPA the H that shows is normal. H for our phones(atleast on the international version) is a combo of HSDPA and HSPAP which in tmobile USA's eyes is 4g and 4g+. even though technically its 3.5g and 3.5g+. so need a bit more info on your end to get an idea of what SHOULD be happening.
phone model? international? ATT? tmobile? heck sprint?
provider?
maybe country? it seems like your in another country i think?
and if your in the USA then maybe city you live in? cause LTE on tmobile has only rolled out in like 10 cities though ATT has better signal

but bad reception, so i flashed another few rom until i notice my phone can not get the signal at boot. Thankfully, jaythenut tech me a method to solve the signal problem, but it cannot get the LTE now....very very strange

Choose the first option in the list that comes up, and see what "preferred network" is set to. If it doesn't say something about "LTE" theres something wrong.

Hello. We're you able to resolve the issue?
Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?
Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.
hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?
Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).
this is easy.

Hi,
So I'm having an issue keeping an LTE signal. I use straight talk with at&t and I can get LTE if I turn the radio on/off, but it will always switch itself over to 3G at some point in the same location. There are apps that can force it to do LTE only which works, but I can't make or receive voice calls over LTE.
Does anyone know how to fix this? This never happened on other phones on the same network. In my specific location I get 2-3 bars of LTE and 4 bars if switched to 3G. I guess it wants to keep using the better signal.
Also at home where I have full signal LTE and H+, it will choose H+ over LTE.
Had same problem. Switched sim slot to the other. 4g again. Try IT?
Did you try different APN settings? I'm guessing you already checked the preferred network option.
Sent from my MIX using Tapatalk
APN settings are good and I can get LTE if I flip the radio on and off...it just always wants to revert back to 3G at some point. Same thing happens in sim card slot 1 or 2

Which rom are you on? I remember there's a specific rom that has a bad modem file. Trying updating to the latest version.
Maybe you can solve it by going to APN settings and set APN protocol -> IPv4 and APN roaming protocol -> IPv4 . That worked for me. I had the same issue.
Or try IPv4/IPv6. That's network related and maybe IPv4/IPv6 is correct for you.
I have to set it every time I flash EU or EPIC rom.
Good luck.
did you ever figure this out?
I'm having a similar problem on a Note 4 Global. Only it switches to 3G for a voice call and never switches back.

I've updated it, and it's all the same. Once in a great while it will switch over to LTE on its own, but 99% of the time it will just sit on H+ forever even though I know the LTE is fine wherever I go.
I guess this is just how it's going to be.
I finally fixed this by wiping everything in twrp and flashing a newer version of the global stable rom. LTE works fine now, and it doesn't stick on H+ when I make a call anymore.

That's interesting. I guess Xiaomi fixed the bug in one of the releases. I wonder why you had to wipe everything though. What if we try to flash the latest modem. Is there a link to that? Would that work?
Would modem be the same as firmware? There's a thread on here that has those. None of them did anything for me.
My LTE problem is isn't fixed after all I guess. Once it loses LTE, it still never reconnects to it on its own and goes to H/H+ forever.
I guess the only thing that I've fixed is that it actually switches back to LTE after a phone call.
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!!

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.
