I had purchased a second hand o2 xda neo. It had wm 5 on it . I updates it with wm 6.1 roms available here.I find that the gsm reception is very poor inside my home.I dont know whether this happened after the update. In my office it is quite good. Even when I am outside i have no problem. Only in my home the signal is very weak. can this be corrected by some registry tweaks or some software. or is it a hardware problem. and if so can i get it repaired. pls help...
what rom are you using and what radio was recommended for use with it. Sounds like a radio issue to me but plz tell me rom and radio. you can experiment using different radios found on the wiki to see whatworks best.
you can flash different radios without loosing data on the device.
I have tried with 2.19, 2.47, 2.69 roms. but no effect. I am trying today 2.07 let me see if that helps. Does IPL/SPL effect the singnal strength?
mmm it might be just one of those things, in that there is interferance within your house (my house is made from granite so reception is very poor), if recpetion is good elsewhere it is unlikely to be radio.
Is there 3G network there? The quality of service on 3G can be unpredictable at best of times.
Signal is not effected by IPL/SPL to my knowledge.
The results of 2.07.20 radio rom. It shows good signal but i feel that it does not update it when the signal is poor. In my office signal is good. So it showed full strength. I went home. There too it showed full strength. when i did soft rest to clear my doubt the signal was poor as in previous roms. Do you think that the antenna has some problem. Can it be replaced. i find an opening above the mirror( near the camers lens) for car antenna. Can this help? if so how?. 3G network is not available in my country(INDIA)
hey,
i think u might have to accept that the signal is just crap in your house... a bummer i know, but if youve tried various radios and signal is good elsewhere, it cant be the internal ariel.
have u tried flashing another rom, more recent build?
Not sure it will help but you never know... at the end of the day, signal is never constant in any one place.
But friend. The signal is good in other phones. If the signal is crap then it should affect other phones too.
I should have also said that the signal is never constant betwenn too phones in the same place. It depends on antenna hardware and the location of it, like signal is reduced whislt making a call if you place your hand and fingers in the wrong place.
I think it unlikely that is a hardware issue if your signal is fine in other areas. Sorry my friend i dont know what else to suggest having tried radios and roms.
The prophet is getting a little long in the tooth now, so be time for an update?
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!
So here is my issue, my Wifi signal is very weak, like all of my friends will be able to connect to wifi meanwhile I have a very weak signal or it takes like 5 minutes for it to actually connect, If however I am close to the modem the connection is fine.
My data and Phone signal are perfectly fine weirdly enough, Ive had this wifi problem, for like 6 months now, and went through like 4 different Roms, nothing same Wifi Issues. A long time ago I had problems so I flashed a modem file, I think that I may have at the time did this inccorectly or simply chose the wrong one, or its something else I dont know.
Currently I am on CM13 Optimized by JDC Team using a Samsung S4 SGH-I377M with Rogers
Then flash a new model file.
The non-hlos is related to Wi-Fi, but you might want to update both, the gsm and the non-hlos.
And don't use metallic cases/bumpers or anything on your phone, they reflect the signal.

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.

Whats your phone model, where are you using your phone (Country and network) and what type of network? LTE, 3g, GSM?

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.

I have same problem as @paipa, tried this, nothing changed, therefore I think aluminum bumpers have nothing to do with it.
64 dBm ... and 23 asu before with HK firmware 4.4 and CN radio
107 dBm ... and 3 asu now with RU firmware 5.0 and RU radio
Celular network type HSPA

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)
Yes, but after that I will have the proximity sensor problem, I saw someone from forum lose the sensonr, because was allways online :|
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,
This problem is also being discussed here: https://forum.xda-developers.com/yot...tive-t3520013/
I am having bad signal all day long wherever I am. I wonder if i can change modem to see if there is any improvment ? I am using XT1642 with " M8952_70030.25.03.62.02R " baseband version . I want to change modem to get better signal ? or is there any thing i can do to improve my signal rather than changing lte to 3g ?
No, you cannot and you should not play with it.
Your attempts to play with modem will give you more troubles (SIM not working, IMEI lost, etc, also a cause of losing fingerprint sensor)
If you search in other threads, if modem is corrupted/changed, then they have such problems and they are unable to get original baseband back..
So keep it as it is.. that is something that Motorola gives updates for it.. you don't touch it..
thank you for your comment but I want to see my options cuz with this signal quality I cant use my phone at all mobile standby drain bad phone calls etc.
That's something you need to ask to your network provider.
Best will be if you ask your friends/family near your area for which network they use and how is the performance in that area and choose another network..
From ROM side, it can be 'ril' issue, but most of nougat roms and stock rom are best without any ril issues, can't say about oreo.
Nothing else you can do for this issue...
My sisters phone has name signal quality with mine in terms of dbm criteria yet when I looked at her battery stats I saw that she has no battery drain caused by mobile standby that interesting.
ps: she uses samsung galaxy j7 exynos variant
