[Q] defy signal problem

Hi all i got a defy green lense and having signal problems.
I have been using cm7 and now cm7.2 since using non stock roms my signal has been playing up majorly.
Sometimes cant get a signal other times i'll get a signal but only hold for a while
Most annoying the signal "unlocks" when the screen locks and then takes ages to lock back in again.
3g problems too.
I have tried all the basebands and different sim cards and networks but still the same (ok when i put into another phone).
I have checked inside the phone (had to replace ear piece again) and nothing is broken or dirty.
i did read somewhere that it could be the radio files on the phone but i thought baseband swithcer did this?
Any help would be great as its getting annoying now also i noticed wifi locks out sometimes too when screen in locked?

What service provider? Where are you living?
I was facing a network issue too. I had to switch my baseband to "China MEE 810/2100" as i use VODAFONE IN
see with your network provider if you have set the correct baseband for your area

I've done all that and it has the same problem on any network and Sim.

WOW this prob just hit my phone this morning.
i went to sleep last night and everything was fine
woke up this morning and had no data and my defy says Emergencies calls only.
i tried putting my Sim into a g2 and works perfect. tried resetting the defy and changing the base band and nothing... only one that lets me make calls and gives me 2g is Australia base band. i even flashed a fresh sbf and im still having the same issues.
if anyone out there knows how to fix this issue please let me know i really need my 3g back.

HELP! SOS!

I'm not too worried about the 3g it's more the annoyance of the signal cutting in and out.
Is there a way can change the radio files on the phone without using Baseband switcher so I know it's actually changed then and not looking at lots of files?

Visit the below mentioned link and use baseband switcher tool and try switching between US T-Mobile 3.4.2-107-4 @ 850/1700/2100MHz
or
US T-Mobile 3.4.2-107-9 @ 850/1700/2100MHz
or
US T-Mobile 6.xx.0 @ 850/1700/2100MHz :

Also make sure that your phone is not in Airplane mode from Settings
Use the steps and share the results!

Tried the baseband already, put stock rom on and the signal is better nopt switching on and off so why does this happen on cm7 etc?

Just an update on this...
Flashed phone to cee deblur stock rom and signal was OK so worked out it must be a software rather than hardware issue.
So using the PC method I flashed the phone 3 times and wiped all the data each time.
After that the signal was still OK so I install 2ndinst and loaded cm9 cm9 kernel and gapps. Wiped data and the phone has been fine apart from 2 lock ups. I'm getting 3g and the signal is not being lost. After installing cm9 I also installed rom updater ,after 1st reboot it updated Android and now my camera green lenses works too not 100% quality but that's what my dslr is for! So for people getting the signal being lost abd no 3g problem try a stock rom a few times and wiping phone then custom rom worked for me!

Czech republic signal issue
Hi,
I have signal problems too - Vodafone CZ user. When I have no signal uderground - when I go down by escalator signal just disappears. Its verry annoying in case of using mobil tickets.
Im using WajkIUI™ ROM based on MiuiAndroid 2.3.7 (GB) on Defy+.
Have you any sollution for this?
Thank you

I have the same problem. There is no signal in underground or even in elevator! I checked it with cm7 and whiterabbit. I think it doesn't depend on rom. But I believe it's software problem.

Problem in Base Bands
I have problems when I switch to 850-1900 frequencies, the ones that works in America, Argentina.
I tried everything, differents roms, stock roms for Arg carrries. APN are correct, Baseband selector for Defy is correct, set to Americas, argentina,
I bough this phone from ebay, it seems to have been designed for UK Ireland according to motorola support, I haven't reached the UK support because they're currently closed.
When I am in 900-2100 Bands the phone works perfect EXCEPT for 3G, H Connections that don't work at all.
Is it possible that this phone has a different hardware ? I read that it may can be solved with a new Base Band for America but how do I go with this?
Thanks

3G Only Working Intermittently

Hello
I've been using Quarx's CM10 for the last 3 months, and up until a month ago it was working fine. Then suddenly, after putting it on flight mode for a trip, my 3g has stopped working reliably. It hasn't completely stopped working. Sometimes it works for a bit but will then just completely drop out again. I'm not sure if this has anything to do with the RIL bug but I don't seem to be getting any reboots so I don't think its this, and GPRS (voice calling, text messages) all works fine. WiFi also works perfectly.
I have recently moved to WIUI GB as I thought maybe there was something up with Jelly Bean. Anyway, exactly the same issue is presenting on this rom as well.
I'm on Vodafone Australia, using the Telstra Baseband (EPU93_U_00.0.00) from the baseband switcher.
Android Version: 2.3.7
Kernel version: [email protected] #1
Build: MIUI-3.1.27
Bootloader 7
Any help would be much appreciated.
Thanks

So I've checked a few things. It's not the SIM card as I had it swapped by my service provider and the same problem persists.
Also, I put my sisters Optus sim in and it seemed to work no problems. Just an odd thing I picked up, but when my SIM is in the phone the Data symbol is always on "H", whereas hers showed "3G" unless data was actually being used and then it showed the "H".
Anyone got any ideas??

[Q] Mobile data problem

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!

Samsung S4 3G issue

Hi guys
I’m new here and I need your help.
I have Samsung S4 International bought on amazon in US, no simlock.
I use this phone in Ireland in Europe.
Everything was ok until a few months ago when I lost 3g connection. Science then my phone is working in 2g only mode (gprs/edge speed)
Phone was running on stock rom android 4.4.2, I thought it is a software issue so I rooted phone and installed CyanogenMod. Unfortunately it did not help 
Phone still synchronise with 2g network instead of 3g even in capital city next to BTS.
I was wondering is 3g module broken and what could be a reason of that? Do you have any idea how could I fix it, what would be a cost of doing it and is it even worth it.
Except that, phone is working ok. GPS with finding a fix is a little bit slow but this is not a big issue.
Thanks in advance

Current details about phone:

Kernel 3.4.0-cyanogenmod-g2ab6e0f

did you try any other sim cards?

I9505 Signal problems

Hi
For a very long time I've been having signal problems, it just suddenly stops working and I have to reboot to get any signal back (airplane mode on and off doesnt work).
Its a GT-I9505
4.4.2
Goldeneye Rom
Greetings

which network? might be a local network issue?
I'm with 3, and although officially their website says that there's no planned maintenance in the area, i quite often drop signal when I'm at work recently, even though it's worked fine until now. I think a lot of people on various networks get the occasional network issue though. I think companies are constantly "upgrading" things, leading to network outages. I don't know why they don't just leave things alone. I used to have perfect signal on t-mobile when it was 3g, but as soon as they changed to ee and started to move to 4g, I got no signal, ever....that's why i switched to 3 in the first place, but now that they're "upgrading", same stuff again!

Its not the provider, know a lot of people on the same company and only me and my brother (same phone same firmware) are having this problems.
I read it coul be the 4.4.2 firmware, but dont know if only updating would fix it.

I had this problem on an earlier version of a cyanogenmod nightly. Most likely is your custom rom causing it. You said it yourself. Both you and your brother, same rom, same phone. Try a different rom or different version of the same rom.
