Every custom ROM for Redmi Note 4 SD has a bug that is making LTE signal disappear, you can verify it by opening signal info in settings.
You can see that the dBm signal stay at normal value but "asu" value is constantly spiking to "99" which causes signal indicator to show no signal for brief moment.
This happens for every ROM that is not based on MIUI.
Does anyone know what is the cause of it? We have sources released, is this a kernel issue or something else? It cannot be modem firmware since we are using same as MIUI. Can this be diagnosed/fixed ?
I remember it was the same few months ago, and still nothing has changed. I think it's the biggest issue and im wondering if anyone is trying to work on it.
Edit:
Best explanation: https://forum.xda-developers.com/showpost.php?p=76811230&postcount=157
I will mark this as resolved.

Does it actually lose signal or is it just a visual problem?

This doesn't look like a cosmetic defect. I was on MIUI Nougat and didn't face any issues with signals. After coming to RR Nougat, I can see frequent fluctuations in network. Lesser speeds, much less consistent connectivity. I have tried changing the sim, compared with a phone running MIUI on the same sim, there is an undeniable fluctuation, with intermittent loss of data. This seems to happen only when data is enabled.

Yes, worth mentioning is that the issue is with LTE (4G) with Data enabled, i didn't noticed any signal issues or disconnections using 3G with Data enabled. Someone smarter should look into this.

I'm trying to decide whether to send my HOX+ back to HTC or not.
Since the 1.17.401.1 OTA update in December I've had assorted mobile signal problems see http://forum.xda-developers.com/showpost.php?p=36221014&postcount=88 which I was certain were s/w problems.
I can now drop the mobile signal (no bars with x) and any connected call every time just by starting the *#*#4636#*#* phone testing menu (if ithe test menu is already running the connection does not drop). This and the fact the signal frequently drops to 1 or 0 bars makes me wonder if there is a h/w fault.
Can anyone else with 1.17 s/w report if their connection drops when they start the test menu?
Any suggestions as to whether waiting for another OTA update or returning it would be the best bet? I've already done several factory resets & installed the RUU twice.

You don't get any mobile signal changes when, for example, browsing over wifi?
The reason I've been looking at the test menu output is that I get a consistent signal drop from 3 bars (-91 dBm) down to 1 (-107 dBm) or 0 when using the browser over wifi. I'm not sure if it's the wifi traffic, increased cpu load from idle or something else but it shouldn't affect the mobile signal.

The radio goes totally off around 5 times a day - be it with or without wifi. I also contacted HTC about this and they suggested to wait for the next update (as probably this is a software issues, not hardware...).

I'm pretty sure it's software as the phone was fine before the OTA.
That almost sounds like an admission of a fault by HTC - I don't suppose they gave any timescale for an update?

Do you have GSM transmitters in your area? It is possible that the phone does not capture coverage and increases the power to keep this coverage. The battery may also be defective. How long has this problem been with you?

I think it's not from the battery.. Look the time without signal in the photos... Above than 70%. So I'm with x829, can I flash just the modem? I live in 2 citys, one of them its Sofia (capital of Bulgaria) and here should be the best signal in Bulgaria... With my Xiaomi Redmi Note 2 I haven't this problem before. Can you prefer me some rome? I need B3 frequency for 4G signal. And thank you for the fast answer
Do you have TWRP? If you have this, you can try other ROM for example Lineage Mod and Test whether the problem has disappeared or is still appearing. You should check on original ROM too. Also, there may be a problem with antennas.
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 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?

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.

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.
Hi there,
This issue is a weird one, but I also had it on my old OnePlus One.
So I travelled to London on Tuesday, and I noticed on the train ride that my signal kept dropping out, thats fairly common, as its fast moving and passes through signal black spots. The weird thing is, when I'd regain signal, it would show a full signal bar, and 4g logo, but had a cross next to it and said no internet access. If I rebooted my phone, it would then regain internet access again. I got the same issue just walking around London. Full signal bars, but no internet, and a reboot would bring back internet access. Airplane mode toggling didnt fix it. Im from the Midlands, so my theory is that maybe when my phone gets passed over from one signal mast to another, it causes an IP issue or something? I used to get the same issue when travelling up north too on my old phone.
Could this be an issue with Lineage or Lineage based OS's ? My OnePlus One did the same thing and that was running Lineage OS 14. On my Poco F1, im running crDroid which is Lineage OS based.
My only other theory is that maybe there is an issue with my SIM card? Im using the same SIM card which was in my One, in my Poco now.
The only common threads between the two phones is that they both have Lineage based OS's, and they are both using the same SIM card.
Does anyone have any suggestions?
Thanks!

you have to do this every single time you boot your device.. set it for both radios, then disable radio and re-enable them / toggle flight mode on and then off..

I'll give that a go and see if it works. I didnt realise there were so many network modes to choose from. I have a lot of modes in preferred network type settings too, ive got it set to 'GSM/WCDMA/LTE' at the moment.
I do have a private DNS set too(cloudflare 1.1.1.1), could that be causing the issue maybe?
I'll see if there are additional settings I should have on according to my network provider.
EDIT: Just checked, and my APN settings were on the wrong network, could explain the issues.
set it to an option with PRL, do not use the in-device settings page, as it is not suitable for global use (rather china oriented). use the hidden menu as suggested above.
also it's always good to replace an old sim.
APN is very likely a cause as well, especially when roaming.
I have noticed this the signal does appear to have issues.
I had same problem when I had mi a2 lite I found the signal not so great but this phone you would expect to be better then that one.
I use two sims both on different networks which also use different bands well on sim1 others phones max signal on 2g/3g/4g but on this one it doesnt want to drop below 4g and the 4g signal is all over the place at times its two bars.
now on to the other sim this network around my home has always had poor 4g so with other phones it would drop to 2g/3g which i would then get 4 signal bars not on this phone again tries to stay on 4g with no siginal and if you select option to choose different preferred network the signal on 2g/3g is 1-2 bars only.
i tried let/umts pri on one of the sims made no difference.
I have tried this outside my home as well same thing it's only when i am really close to a mast will i get max bars for both.
Hi mates,
My mobile POCO F1 not showing any signal strength, I tried doing factory reset but no go same issue. Could some one please help me.

Using Jio and doesn't have any such issue. But I have noticed one thing. Internet speed becomes slow sometimes even with 4G+ sign. It looks as if miui throttles internet speed occasionally. But overall, I am getting quite good network reception.

Don't know if this was for the same reason, but I was experiencing signal drops but only when I was home. i think it was because of wifi calling. Disabling wifi calling and voice over LTE improved the situation. Again, Signal was fine when I was outside. Only when I was home. Use the following codes (in phone app) to switch between turning them on and off. Let us know how it goes.
