Been having issues with my phone where once it while it would disconnect from the network (happens daily). I live in Hong Kong and am using 3 as the network here, and am running RomAur 2.31 with PureXAudio.
(1) Has anyone had those types of issues?
(2) Are there any flashable RADIOs? (I remember updating my radio version on my previous Nexus handset, but haven't seen anything like a radio release here in the forums)
Thanks!

Yes, but not with that ROM you mention (well actually I am using 2.3), I had constant issues as you mention with only .350 ROM. Is anybody else asking the same question as you for that slight upgrade from 2.3 to 2.31?
Not aware of any other radios available for this phone, it is too new. The radios that you see around are typically created by the phone manufacturer, and as time goes on you end up with a great choice of radios to flash with notes about the good and bad people have discovered along the way.
Why did you update the Nexus radio, where you having similar issues or issues with your cellular provider?
All I can recommend is to factory reset and re-install the ROM, of course make sure you back everything up so you can restore it afterwards.

Singapore with SingTel. Disconnects from Network for no reason in a open location also and connects back itself in few seconds.

So, when you say this are you getting the X through the red network strengh indicator at the top, if not then your phone is not disconnecting from the network, just switching modes or towers

Yup, same here.
I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?
Mate i have exact same problem
I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks
Also experiencing this with Tmobile UK.
Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.
No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.
I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy
Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.
Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon
I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.
Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.
I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?
I think they're not available yet, at least on lollipop...
Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?
All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?
Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!
About a month ago I noticed that my wi-fi is working weird. It is connected, but I can't use the Internet. Looking at the wi-fi icon I can see that it is sending data to my router, but it is not recieving anything back. I basically have the arrow going up, indicating upload, but no arrow down, indicating download. After a few minutes (or after restarting wi-fi) it goes to normal for some time and then it stops working again. I'm currently on optimised CM12.1, but it doesn't matter which ROM I use. My router works fine. I checked with another phone while my s4's wi-fi wasn't working. I was considering updating baseband and modem, but I wasn't sure which one to use. I'm in Poland and my carrier is Mobile Viking, but they use Play infrastructure (or T-Mobile, if play is unavailable). It isn't anything that would make me change my phone, but it is a bit annoing.

It's like you said. The only thing you can try is changing your modem.
Do you have a stable connection on other wifi networks?
I have no way of checking other networks (living in a small town with no public wi-fi). Which modem should I use? I'm in Poland nad I bought my S4 in a store (not from any carrier)

There is no best modem. You have to try it for yourself. I would suggest taking lollipop modems, but you have to be on a lollipop bootloader for that.
If I am on lollipop rom, does that mean that I have lollipop bootlader? When I bought my phone it was on android 4.4.2
Since lollipop my wifi has been terrible on my i9505 stock rooted. My iOS and windows devices are rock solid but sgs4 has crap connection strength. On previous devices the radio with the upgrade was normally to blame but I'd welcome any suggestions. Does cm12 use the same radio as stock?
Hi guys.
I wanted to try a custom ROM on a friend's i9505, so after reading a bit around the forums I updated the phone's modem and bootloader (all ROM threads seemed to recommend this one):
http://forum.xda-developers.com/showthread.php?p=62593102#post62593102
And then tried a few ROMs.
However, they all seem to have the same issue: the WiFi signal is INCREDIBLY WEAK. If I'm not literally 1-2 meters away from the WiFi router it just loses the signal. Where other phones see a full or almost full signal, the s4 doesn't even see the network, or it sees it with just one "bar".
So, discouraged, I flashed back the stock ROM, using the instructions from here:
http://forum.xda-developers.com/showthread.php?t=2265477
using the "Latest Lollipop" file in that same page. I see from Odin that it indeed flashed everything, including the modem.
But the WiFi signal is still weak! Everything else is perfect, seems pure stock, but that one thing just doesn't work!
How do I get it working again? I'm not even concerned about custom ROMs anymore, I'd just like to have a stock (or anything really) with a working WiFi.
Any ideas??
Could there be a loose connection in the phone?

Anything is possible, but it seems weird that it happened just the moment I flashed a new modem/rom, don't you think?
Yes, it is rather coincidental, but you never know. I recommend checking it just to rule out.
Was the phone purchased brand new from a carrier?
Well, I tried everything, flashed countless different stock packages and modems, disassembled the phone and checked and re checked the antenna, even brought it to a repair guy who couldn't figure it out.
I guess I'll have to take it back to Samsung and pay their extortionist repair fees...
Yes I had also issue on WiFi after flashing ROM.. Most of the time WiFi saved and secured but not connect
I might have been sloppy with my searching, but I haven't found any threads dedicated to reception issues by Yotaphone 2. Mine constantly loses signal and drops calls even though I'd never had such problems with my previous phones in the same places. I have tried every possible setting (limiting to UMTS, even GSM) to no avail. Reception isn't exactly amazing where I live, but it's definitely good enough to provide stable and reliable service to any average mobile phone. Not with a Yotaphone though.
I also did a side-by-side test using my wife's LG G2 Mini and Network Cell Info Lite. Both phones used the same provider, same base transceiver tower, same sector, channel, every single ID was identical. I took about 50 measurements on both phones in different rooms, out on the street etc. And the Yotaphone had a 10.5 decibels weaker signal on average, which is just insane: 10x less power received by the antenna than the G2 Mini's.
I'm running Lollipop RU 134 on a YD206 (deduced from the 35969 IMEI, despite the About menu saying YD201 due to the firmware). I am aware a better choice would have been CN due to the different bands but during this comparative test I was using a channel that is supported by the RU radio too, so I'm afraid this is an antenna hardware issue which no firmware update would help.
I welcome you to post your own experience with signal reception. I still wonder if this is due to a faulty unit or a more widespread issue. I'd also welcome any solutions you are aware of that have been proven to work.
You have answered your question by yourself. Install CN-Radio.
That's good to hear. One problem though: I just ran yota flasher and saw there was no 5.0 CN release so I'm not entriely sure how to do it. If I flash it with the Hong Kong version (5.0 HK.1.66) will that do the trick too? I'm too novice to perform a radio-only flashing, I know I'd end up bricking my phone.
EDIT: So if I get this right, even old 4.4 CN firmwares have radio that can be paired with a 5.0 RU. My only question is, because I haven't seen this mentioned in the sticky, do I have to do the power+volume down dance when I'm flashing radio only?
This is very helpful for yotaphone beginners:
https://forum.xda-developers.com/yotaphone-one/help/guide-everything-to-yotaphone2-t3547194
I have flashed the CN radio. My baseband version is S01_003_3034_CN1_M05 now.
As it turns out, it didn't help my situation one bit. Signal is as poor as ever, still the same 10 decibels lower than the G2 and sometimes cutting out altogether. The CN radio may have added an LTE band or two but ultimately it's like rearranging deck chairs on the Titanic. This antenna can barely hold a 3G signal, let alone access 4G where I live. Thanks anyway.
Exactly the same problem with my YD206. I run a Russian rom and the phone shows its YD201, but I know it's YD206. I tried changing the radio from the Russian 1.1.134 rom to CN radio - S01_003_3034_CN1_M05, no improvement, tried S01_003_4240_RU1_M05 radio, still no improvement, will try all the others these days and will post the results. Also GPS reception is terrible, almost unusable.
I have just as good reception with my samsung as my 206, so i guess something is not as it should be with your yota.
From my own experience with a former phone, messing with the radio can cause lasting problems. I got rid of mine om my Motorola by nothing less then leaving it with the battery out for some time and then going straight into download to reinstall the radio before it booted.
Would running the yota dry to perform a similar operation help? I don't know, it could be just your phone having antenna problems or something completely different. But i quess there is no harm in trying.
You could also try flashing HK radio.
if you purchased the aluminium bumper, remove it...
I also have the YD206 and reception is good with my phone, I use the radio from the latest HongKong Lollipop, it's different in size from Russian and China ones, and since my phone came from HongKong I decided to use that one and indeed seemps better. Yyou cand flash only the radio and try yourself, just put your phone in flash mode and with the correct radio folder in the yotaflash installed folder, flash with the following commands:
fastboot flash modem firmware\radio\NON-HLOS.bin(ENTER)
fastboot flash sbl1 firmware\radio\sbl1.mbn(ENTER)
fastboot flash rpm firmware\radio\rpm.mbn(ENTER)
fastboot flash tz firmware\radio\tz.mbn(ENTER)

No it's not different to the Russian one, HK.1.1.66 and RU.1.1.124 have the same radio. I just ran an md5 checksum on both, and all files are dead identical. The only thing worth trying is 4.4.3-S01-003-HK1.0.3.61A which is different both from both the RU and CN radio. If it doesn't work, I'm giving up and accept that I received a defective unit.
I tested 4.4.3 HK radio, no improvement. I'm afraid it's the end of the road, I don't see anything else left to try. Since I don't believe in black magic, I'm not going to bother with running the battery dry before flashing, but if someone does it with success, I'd love to hear about it.
I'm so sad. I love the device, I love the e-ink display, battery life is fine as well. If only it worked as a cell phone... Perhaps I was just unlucky and could order another one which may work but I think I'll just cut my losses here.

YD206, Germany, E-Plus on 3G (LTE is crappy where I live anyway). While E-Plus is the worst provider, this is definitely, 100%, without a shadow of doubt not a provider issue. I've been with E-Plus for several years and none of my phones had any problems whatsoever. As I had written previously, the problem isn't the bands, it's the crappy signal no matter the channel. Repeatedly measured and confirmed to be 10 dB weaker than a 3 year old, low-end G2 Mini.
AFAIK nobody has done signal strength tests on the Yotaphone on this forum. I'd be interested to see if this is an isolated issue or if Yotaphone's antenna does in fact suck. It's not something you think about if service is good around you, but full bars don't mean much on their own, as the range is huge: the bottom end of full bars is 20 dB lower (100x weaker) than a really good -70dBm signal, and 300x weaker than a perfect -65 dBm.

Well, I have to test that in real life (moving often), but Lollipop have lot of bugs with radio control, network and Wifi, Marshmallow should not take long to be released officially from Yota, lets hope.

64 dBm is lot better than 107 dBm for signal, so you should flasg HK/CN radio on your RU firmware 5.0, you can flash the radio only.
check your correct files (HK/CN radio files) location and the location of fastboot command and do as following:
fastboot flash modem firmware\radio\NON-HLOS.bin(ENTER)
fastboot flash sbl1 firmware\radio\sbl1.mbn(ENTER)
fastboot flash rpm firmware\radio\rpm.mbn(ENTER)
fastboot flash tz firmware\radio\tz.mbn(ENTER)

YD206 all the same?

As it seems that's truth, I have wrote this about it:
I discovered that I also have this problem, I was with the wrong radio, had to flash the Chinese radio and it suddenly appeared, this is what I have found I have an YD206, YD201 also seems affected with the same problem after a chat with a Spanish user with original YD201 Russian Lollipop and Russian Radio :
On YD206:
With wrong radio. radio (Russia xx versions) on YD206 , in KitKat or Lollipop ROMs the proximity sensor is OFF by default BUT, as soon you turn ON an app that uses it, it won't turn off again, it keeps blinking even if you force kill the app that started. However it will turn off if the screen is off, after 5 seconds after. Also it's important to acknowledge that 2G only with this radios fails. On Lollipop Wifi won't turn off automatically, just manually.
YD206 With the correct radio. radio S01_003_3034_CN1_M05 2G 3G (UMTS) and 4G (LTE) all work and with better reception, but as soon the screen is ON, the proximity sensor starts working, does not matter what app you have open, when you turn OFF the screen the proximity sensor will turn OFF in about 5 seconds. If you are using the EPD screen the proximity sensor will turn OFF faster than 5 seconds, but as soon you touch the EPD it will turn ON for 3 seconds or so. On Lollipop Wifi won't turn off automatically, just manually.
So the problem acts differently when you flash a different radio, I am not sure where's the bug comes from, but it seems there's also a bug with YotaRom. There's a Xposed module to disable proximity sensor in specific apps, I haven't tried that, I also would like to know how this behaves with the Marshmallow Beta.
(For the ones that are not aware of this problem, keep in mind that to see this problem you need to be on a dark place to see the very faint red light of the proximity sensor.)
Best regards,
