Guys. I just bought F1 and I've noticed something about network and I need help
I've used Redmi note 5 Pro before, here in my area 4G signal is weak and I get about 2 bars signal and full bars 3G signal. But the 4G have much less ping and speed. So I usually use the code
*#*#4636#*#*
And change network to LTE only. It works good in RN5P and it never changes network afterwards
But Poco F1 overrides the settings and still switches 4G and 3G even tho internet is good. So is there any way to unlock LTE only mode in MIUI?
Also if it needs root it's okay. Im going to unlock tomorrow. Please help guys.. thanks

No need to root or use codes.
Simply enter settings, simcard, operator (name), preferred network type. Choose the desired type you wish to use.
FYI if 4g network where you live doesn't support voice over 4g than your phone will override the setting and force back to 3g when you receive a call.

Hi folks, I'm not sure if this thread is stilled viewed often. I have a question and I thought I found the answer somewhere.
I just bought the 990 to use on Fido / Canadian. I read after my purchase that Verizon blocks LTE on other networks, even when unlocked.
But if rooted, and mine is, that you can unlock the LTE.
Is that true?
And if yes how do I unlock it?
Thanks
LTE isn't blocked. Does your carrier use the same LTE bands as verizon?
Yes, most not all. I have it working now.
After a phone restart I need to click no to a prompt for global access. Then I need to set my connection to LTE/Gsm/Usomething. Then I need to ensure LTE legacy is set.
Then I must choose join preferred network. It connects to 2g or 3g.
Then I need to wait about 5 minutes and try clicking preferred network again and it joins 4glte
Happens this way after a restart every time.
It seems to me that with time it will connect to LTE even if you don't click anything... I have a local Lithuanian SIM in my V10 right now (pricing is so much better than anything we can get in the States...). First day it was only doing H+ at best (although at 10 MB/s Speedtest shows I wasn't complaining). Today I noticed that it switched to 4G LTE all by itself, and is pumping 63+Mb/s, which is better than anything I've seen on Verizon itself...

Hello,
So I've been using my Xiaomi Redmi Note 3 Pro Global Edition (kate) for a month now.
Everything's been going great except for one bug that's really annoying : when I enter an rural area with only EDGE, and then get back into an area that has 3G, H+ or LTE, the phone doesn't switch back to a better data network.
I've found a trick that allows me to get a better network back, by changing the preferred network type to 2G and then to LTE again. Only then does it finally detect the LTE network. It works but it's annoying to have to do this everytime I want to search for something quickly.
I'm currently using CyanogenMod 13 for kenzo with kate modem flashed, but I don't think this is the source of the problem as I previously used MIUI 8 and there was the same problem.
I live in France but I'm almost sure the bands are not a problem as I can receive LTE, but it just doesn't switch to it when on EDGE.
I'm hoping you have some solutions.
I recently purchased an Xiaomi Redmi Note 3 Pro phone (kenzo), it covers all the bands that rogers uses in my area in Canada, I believe.
https://en.wikipedia.org/wiki/Rogers_Wireless
I can connect with the phone on LTE, HSPA+ with no problem, if available. Sometimes, if I am in certain area's, the signal indicator drops to 3G .... it shows a decent signal, but no calls or data can go through.
In this example on the following chart, the first WCDMA connection,my phone only indicates 3G and I can not make a call or use data. When my call attempt is done, it goes back to LTE. Then I try again. Then for the second WCDMA connection on the chart, I am connected as H+, I can make a call and use data. Whenever this phone connects to CID 31072 the problem happens. When I connect to CID 31075, no problem. These are just examples of towers that I reach from my home. I get the same problem occuring other areas.
Any suggestions on what I need to change on my phone? Is my phone making a kind of 3G connection for some reason, which Rogers doesn't support? I have tried everything I can think of, Miui dev versions, CM13, LineageOS 14.1 etc, change Android Radio Menu settings, etc.
Nothing seems to fix this issue.
Any advice would be greatly appreciated!
I have been using Network Signal Guru, and have figured out that the phone will connect calls data on 3g if the band it finds is B5-850M .... if the tower tries to connect to is B2-PCS-1900 the call fails.
I tried to block the use of band 2 with Network Signal Guru, but it seems to still use it when it finds it.
I have since flashed a LineageOS rom and used the Network Signal Guru to disable band 2 WCDMA. The phone has not been experiencing the issue at all since. I am cautiously optimistic that I have found a solution. Still not sure why this band doesn't work here though.
I'm experiencing an odd issue on the SD RedMi Note 4 of my wife (ROM: v8.5.8.0 NCFMIED): where LTE signal is weak and other mobiles switch to GSM (2G) and are still reachable, the RedMi of my wife is still trying to get LTE signal, ending up offline for _long_ times.
I tried to switch preferred mode to "LTE/UMTS auto (PRL)" (mido default choice when "prefer LTE" is selected is "LTE/TD-SCDMA/UMTS", which appears to include the Chinese 3G standard too) like my OnePlus 3, which never looses network, but it didn't help: the only way to have it reliably reachable is switching to "GSM only".
I didn't find anything relevant neither by searching nor by browsing the first 30 pages of this subforum: is there anything we can do to improve this? Thanks!
go to about phone. tap multiple times on total memory, a window will open up. open phone information 1,2. choose type of network you want from multiple options

That indeed solves the issue as I wrote, but I don't think that my wife would be happy if I tell her she has to check the signal all the time and, eventually, _try_ to manually switch to "GSM only", and go back when the signal strength improves... that should be modem job!
Update: the affected SIM was in slot 2; moving the SIM to the first slot seems to improve the mode switch. Still the sensitivity doesn't seem exceptional, or perhaps there is some other issue (1), but at least it seems to correctly switch from 4G to 3G and even 2G where the signal is weak.
Testing in "LTE/UMTS auto (PRL)" mode now (I don't need TD-SCDMA here, I assume there is less overhead with less modes); wondering whether is a modem (read: Qualcomm) issue or a MIUI bug.
(1) sometimes the device still looses the network where my OP3 seems connected with very weak signal (-105 dBm) and LTE Discover reports "Potential eCSFB issue detected" (which sounds odd since eCFSB is a CDMA thing, and there aren't any CDMA network here in Italy AFAIK: could it be the way LTE Discover tells that the phone is unable to handshake an existing network?), until it reconnects. Moreover, it seems that RN4 tends to prefer 3G over 2G even when mobile data is off, which is not a good strategy IMO.
Edit: LTE Discover reports "Potential eCSFB issue detected" also on OP3, which works perfectly: it seems its shown when the terminal was unable to successfully register on a network and stays idle until the next connection attempt
I have sort of similar and opposite problems in the USA.
Mine switches from LTE to whatever H+ is and then never switches back on its own. I'm blaming Xiaomi over Qualcomm.

I have the same problem. I have a weak signal reception in my house. Is there a app that can put a phone to 2g when I am on wifi ?

I tried it, it worked if I used the root option and manually hit the refresh button. I read that the auto refresh only works if the signal is one bar or whatever or less.
My signal is strong when it's on H+, so it would never get low enough to make it auto refresh.
What I need is something that would switch my preferred network to Prefer 3G and back to Prefer LTE whenever I'm on H+ for a while, because that gets me back on LTE every time provided that there's LTE in that area.
My Redmi Note 4x international should be capable to connect to the 1800mhz band, which is available in my neighborhood. Sadly I haven't had 4g or LTE since I've gotten this phone (4 weeks) any ideas why it won't connect?
Vodafone Netherlands in Utrecht city.

Thank you: started testing. It seems that, despite the better signal, even after refreshing the device still ignores 2G and tries to connect in LTE or H+ mode. I'll see in the next days.

Yep, that's very same issue I'm experiencing. I was feeling alone: in the MI forums I couldn't find no one complaining about that.
Did you notice that when the device connects to a Wi-Fi network the cellular signal indicator suddenly rises (it appears to indicate Wi-Fi signal strength) and appears "4G" next to operator's name, even if cellular data is off?
Too bad, if RN4 didn't have such a bugged radio it was a real bang for the buck.

Try to get some more info from the "LTE Discovery" app: is the device registered on the 4G network but internet access is absent or the device doesn't even register on the 4G network? Does the device detect the 4G signals?
In this thread we are discussing about the opposite problem: our devices don't switch to 2G when the signal is weak...

Unfortunately it didn't help: it doesn't seem to improve overall operation. It even asks to refresh the Wi-Fi connection when there is no cellular signal...
There is really something ill in this modem. Sometimes the signal indicator shows Wi-Fi signal strength instead of cellular. I hope some future release will fix at least some of these issues.

Sorry to hear that. Try to report to the developer, so he can solve the issue.

Thank you. I think it's not necessary: since yesterday I'm running MIUI v9.0.3.0 and things improved considerably. I'm quite sure the issue was MIUI 8 which had a complete modem mess, not the app, that was doing its honest work just as it was possible.
Poco F1 (MIUI Global Stable V11.0.8.0.QEJMIXM ROM) has significantly better 4G signal strength than 3G or 2G. In fact I got problem with that, when I'll recieve call or make a call, the phone automatically from 4G goes to 3G or 2G, and in that moment signal strength bars goes from 5 bars (4G) to 1-2 bars (3G) and often other side cannot hear my voice. Later I choose manualy network (3G or 2G) and when I try yo make a call => "Cellular network not available"
What should be the problem? Is it software or hardware problem? ...btw I make a clean install/flash thru fastbot of MIUI Stable V11.0.8.0.QEJMIXM few days ago, but I cannot notice some differences

It means that VoLTE (Voice over LTE) is not enabled or it is not available in your region. That is why it is switching to 3g network to make a call. As for the signal bars, never trust miui on that. Got to about phone -> and find a option where it shows imei, sim status, etc.

Yes, in my country VoLTE is not available, but I don't see that as an insufficiency, I use it only for data/internet 4G.
MIUI signal bars should "work" same for both 4G and 3G/2G, i think it is some other problem. Btw use it code *#*#4636#*#* (testing mode) and there i can manually set my network (WCDMA only, GSM only, LTE only, CDMA, TD-SCDMA/UMTS... and all variations of them). Usually LTE strength signal is "70-80dbm / 50-60asu". When I set to WCDMA only or GSM only it is ""100-110dbm / 1-10asu" and that's in the middle of the city (where I live). When I enter some Mall, stairs of building or hike on local mountains, when I want to make a call, the result is "CELLULAR NETWORK NOT AVAILABLE " :crying:
Does it can be antenna problem? But then, why 4G signal is far better than 3G? Does it have separate antennas??? I got no idea really what should be the problem about that

Without VoLTE you cannot make a call on 4G network. The SIM will automatically switch to 3G/2G. It's the same across all phones, all carriers, and in any country.

It is OK that. I know that. In fact, I GOT PROBLEM WITH 3G AND 2G SIGNAL STRENGTH. I mention 4G just to compare signals. I got 5 bars on 4G and 1-2 bars on 3G/2G on the same location. I have super fast internet thru 4G (50-100mbps), while when I set manually to 3G it didn't even connect data, furthermore, I cannot make a call (Cellular network not available). Obviously it is a strange problem. I'm not arguing about VoLTE or 4G...
Is it the same antenna for 2G, 3G and 4G signal? Should I replace it? I will repeat myself again, I can't get HOW CAN 4G signal be better than 3G/2G?!
I insert both SIM cards (with POCO F1 I use dual sim cards) to other phones (Xiaomi Mi4c, Alcatel Pixi 4, Lenovo A536...) and everything is OK with all of them. So, that means it is a POCO F1 problem.

Try changing slots. Or try a different carrier. The culprit could be your network provider. If the problem still persists go to any service center and get it checked. BTW it is actually strange to see that 3g/2g network is weaker than 4g. Usually it is the other way around.
