I (living in Switzerland) have my Redmi Note 4X ("International", includes Band 20) since approx 2 weeks now. Unfortunately I am having "problems" when on LTE (cellular data). Before switching to the RN4X I had a Mi4c (and before that a Samsung GSIII), so I am comparing to these.
When out of a wifi I "often" have no internet connection. I installed "LTE discovery" app which allways shows signal reception in the bands 3, 7 and 20 (I guess I have seen band 1, too). The bars toggle (even when not moving) from 1 to 4, though. I seldom see a switch into the 3G net.
I am currently running
cm-14.1-mido-firmware (could the modem-FW "in there" be the problem?)
RR 5.8.3
Unfortunately I can't say whether the "problem" described existed from the very beginning (i.e. with the original MIUI) because I switched to RR on the very first day I received my RN4X.
Is this a modem-FW or (even worse) a HW issue? Can/should I
1) download the latest greatest fastboot ROM from here
http://en.miui.com/a-234.html
2) extract the NON-HLOS.bin (which is >80MB, whereas the bin you linked is just 36MB)
and
3) flash it (as explained by T.Ru)
What else can/should I try?
Thx for any advice
Clemens
PS: Excuse the flaky wordings: "problems", "often", "sometimes" etc. but I can't be any preciser
Flash this firmware zip from twrp. I hope it will be fixed

Hi, did you manage to solve your problem? I'm having some too (even if data works fine, I have problems with the voice network, when it comes to receive or make calls or messages).
As of now my "workaround" is setting "Preferred network type" to 3G /

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.
"Prefer 3G" doesn't connect to data network - known issue confirmed by mi hotline
Hi,
I noticed recently that if i select "prefer 3G" from "preferred network type" then the data connectivity is lost. I use airtel network in Bangalore where 4g is good however in my native, 4g network is not that great and in my previous phone it uses hsdpa (3g) most of the times.
I called up the MI India hotline to check if my poco phone is having this isolated issue since i didn't see anyone else complaining. The customer care executive confirmed that it's a known issue and they are working on it. Could other poco phone users confirm that they see the issue?
Regards,
Sudhakar.
3g problem
I've been using xiaomi for 2 years. Most of the phones have 3g problems. There is no connection with H + icon. It's not 10 minutes. If you turn off the mobile data or plane mode, it comes on. Mi4, mi5, mi6, redmi note 4, redmi 5 plus, all MIUI version and android 6-7-8. I've seen problems with these devices and versions. It only happens when you connect with 3g. or 3g preferential. an annoying problem.
Thanks for confirming.
I have quite a lot of problems with this phone.
1. As of now the 4g/LTE is not working too. This happened 2 weeks earlier as well. The service center guys updated the phone to latest and did factory reset. Then it started working. Now again today the 4g/LTE data not working. The phone is on latest software and i even did a factory reset still not working.
2. Many times people told me that my phone is not reachable. During those times even outgoing calls were not happening until i switch to 2g manually.
3. As mentioned already data does not work on 3g.
I had so much expectations on this phone. But now disappointed.

I haven't had troubles, but I don't use data a lot.
I have the Prefer 3G setting enabled.
hmm i have issues on mine 3g sim data card as well . need to on/off mobile data from time to time
Had my x1 for a couple of days now and lots to like about it however I have noticed that it seems to have a very weak phone signal reception.
I am on three in the UK and in the normal areas I travel I have never noticed an issue on my other phones with it struggling to hold on to signal bars.
Anyone else have this?
Signal bars mean absolutely nothing. Many oem even show full bars even when there is actually no signal.
Better install cellmapper app that will exactly show and record the signal where you travel.
Also, do you have 3uk volte working?(calls over 4g network)
Well all I can say is that I live less than a mile from the nearest mast and would nearly always have full signal bars on other phones yet on this phone it drops on and off 1 bar.
I will download the app you mentioned and see what that shows
I've had this problem with numerous Sony phones over the years, always poor signal compared to Sammy's, Pixel's and iPhones that I've had. Same issue with the X1 I have now, always on WiFi calling and no signal, my Pixel 3 XL would be happily sitting on 4G.

Glad it's not just me then.
I do remember having this issue on a previous Sony phone also but can remember the model now. It's been a long time since I had a Sony but thought this one was going to tick every box which it almost does apart from having reliable signal reception which is really should be a must!
Is there anyway they can improve this with software of are we stuck with it due to hardware issues?
I'm in my 14 days returns periods at the moment and like everything about this phone apart from what it should do first and foremost
I am having the same problem, I'm on EE and my LTE keeps dropping from 4 bar's to 1 bar then nothing which causes me to lose data connection. It then jumps to 4 bar's again and then repeats this over and over. This is happening at home where I always have full reception. I have tested my sim in 5 different phones all have full reception and don't lose connection only my Xperia 1 does! Any help would be appreciated.
Same problem for me. I switched my SIM from Galaxy S8 to X1. S8 has 4 to 5 bars while X1 struggles with getting one bar at home.
Ffs... The bars mean nothing. Sony phones take into consideration RSRQ(signal quality) and SINR(s noise) values of the signal. Other oem don't. The actual signal power RSRP (do not confuse it with bars) is same or better on Sony.
Xperia 1 has most advanced modem and antenna setup of any 4g phone. 4x4 mimo even on low bands (first to have it).
3uk and ee are special in the sense that they need phone to support volte to get access to their low band spectrum(band 20).
So make sure you have volte aka 4g calling enabled and check with apps like Netmonster or Cellmapper the band and RSRP of the signal. Then compare it with other phones at the same place.

If it's as simple as that why is it not enabled on this phone already?
I think what you seem to be over looking is the fact that I and others here have said that yes the bars are lower than other phones and flutter slot but also to the point where they drop completely and give no reception at all. A situation not faced on other phones.
Can you explain how we enable this missing band so that the phone can provide a more reliable/stable reception
Does your phone have 3uk volte(4g calling) enabled? Phone should stay in 4g during call. If not then you are out of luck.
ee users can install EE firmware to get Volte working if it's not already . newflasher on xda helps to change firmware.
And please compare signals with abovementioned apps.

If you're having signal drops / dropped phone calls etc... I get it. But Sony is historically notorious for showing lower signals than others on those bars. However, as stated, the bars are pretty meaningless. I've owned many Sony's, and while the bars are lower (sometimes all empty), I still have signal in all the places I should. YMMV.

I don't honestly know. My phone was purchased sim free from carphone warehouse and I use it on 3 network. The phone just set itself up. How would I check this? Is it something listed under network settings?
It's so frustrating as I'm really loving a lot about this phone but just want it to be comparable at least with my other phones I've used with call reception
those who are having signal problem, are you using EE network?
I saw lots of people with EE reporting this issue on official sony forum.
Got mine yesterday from Vodafone and signal is perfect !

Yes
I also have only 1 bar... Orange.
If you are EE UK user, then you need EE firmware on your Xperia 1 to get best network compatibility(Volte and low band support because of it).
3UK users probably need also 3UK firmware but that does not seem to exist yet.
This weirdness of low band access is specific to two UK operators. Everywhere else the device is fully capable of best 4g experience.
Wait Next update

So for those of us on three network but purchased the phone sim free are stuck with the problem as three do not sell this handset themselves so unlikely to release any firmware for it.
That does not look good for me so I think I will need to return within my 14 days.
Shame.
There's definitely a network connectivity issue with the XP1 right now though. This seems to affect only XP1's on the EE network, which were *not* bought from EE direct, i.e. ones with stock firmware. (e.g. mine!)
The symptoms are that periodically, first the 4G symbol disappears, then the signal goes to zero and you've lost the internet. Then it reconnects back onto 4G again. Sometimes this repeats 3 or 4 times in succession. The whole thing takes from 5 seconds to maybe 30 seconds depending on how many re-tries.
You can go for maybe an our or so without a problem, or sometimes it happens like every 10 minutes.
And here's the key part: this happens wherever you are, even on a full strength signal. As far as I can make out, this affects ALL XP1s with stock firmware on EE. EE say it's a Sony problem. Sony say it's a network issue. So we are all stuck.
Does anyone know of a suitable network logging app, which will log 4G disconnects and signal loss, so we can provide evidence to EE and Sony?

(My phone is fine with a Vodafone sim. There's something specific to the phone firmware/config - timers, buffer sizes, packet sizes - whatever - and the EE network. But right now, on EE, it's unusable.)
