Hi Guys,
Recently upgraded from a SGS2 to a SGS3, i ran Paranoid android on my SGS2 for a few months and liked it so as soon as i got my SGS3 i rooted and flashed Paranoid, its been great, but ive just realised ive got an issue, ive not used by Data connection up until now (its been connected by wifi)
Basically my data connection is pants, it flicks between 3G and E but in reality the speeds arent even E worthy
O2 UK
Paranoid Android
Baseband is 19300BWDLI1
RIL was 19300XXDLIB
ive downloaded Getril and tried a few others but none of them seem to help, Any ideas i can try? or any RIL's that people can think of
Why do you assume the RIL is at fault here? Have you diagnosed that to be the actual problem or is it a wild stab in the dark?
Are you able to make calls OK? If so then your RIL is most likely fine. More likely you have flashed the wrong modem that doesn't support all O2s frequencies.
Have you checked you have the right APN setup for O2 UK?
Worst case, go back to stock and test that, to see if it really is something to do with the ROM you're using. I doubt that it is though

You probably want to talk to O2 then. Either they're having problems or the phone has faulty hardware.

My brother had this problem with a galaxy s1. And Other devices. It turned out that it was o2's lack of providing decent Internet signal on there masts. Voice and text was bang on but Internet said e on the network but was actually slower then dial up!
They are terrible when it comes to coverage on 3g.

If you ring and ask about broadband they will probably tell you that it's not available in your area.

Speeds get that bad only if you pass your allowed data limit.

Why would wiping help?
I see this suggested all the time, but no one ever states why.
Right ive flashed a few things, done wipes etc
Phone is now running, O2 UK Firmware (from sammobile.com)
AP:19300XXELL4
CP:19300BWELK1
CSC:19300O2UELL1
When connected to kies it says " your devices current firmware is not supported to update firmware via kies"
Current firmware version: PDA:LL4 / PHONE:LK1 / CSCS:LL1 (KOR) -----SURELY THAT SUGGUEST KOREA? even though i flashed the 02 firmware
my SGS2 never had this problem so loosing the will with this phone already

If you phone is able to make/receive calls fine - then there's nothing wrong with the handset.
Have you checked the APN is set correctly for data?
Assuming that you have checked this and it's correct, then there's probably very little you can do. Can you try your SIM in another phone and see if the data's any better?
The problem sounds like nothing to do with the phone and everything to do with your provider, O2.

I'm running stock O2 UK 4.1.2
Data for me has always been painfully slow, and i mean embarrassingly bad, un-usable unless I'm stood somewhere with a great 3g signal, even then it's hardly bearable. I'm convinced it's the network and not the phone. My icon has always messed about switching from g to e to 3g to h to h+. I think I'm just in a bad area and the phone constantly switches bands trying to find the best one. It just makes mobile internet a joke most of the time.

It is definitely the network. O2 have had the issue quite a while with this. There excuse for Me was you live in the country side. .. Oh yeah coz Leicester is in the country side. . I don't think so. . Try other sim cards and I bet your data is just fine.

Oh and the kies thing is because your csc is set to korean. Root and download csc changer fromb play store. Use BTU as csc but it does perform a wipe.

Thought i would just update this thread now
O2 phoned me last night insisting that it was a problem with the "Settings" and i hadn't turned on 3G etc.. anyway an hour call going through every setting possible and they have given up.
Used a Sim card adapter and put my sim card back into my SGS2 and internet is perfect again... so O2 are sending me out a new SGS3 tomorrow to test that. hopefully it will work and then i can get rid of the Standard O2 Firmware because its awful

Sounds like the IMEI of your phone got corrupt.
Boot it up and type *#06# into the dialer. That'll show your IMEI number. Is it the same as the one on the sticker under the phone's battery?
NOTE: Don't tell us your IMEI! Just if they match. If they _don't_ match, post the one shown by *#06# - not the one under the sticker

Hi Guys,
I recently switched from the Nexus S forums to the Nexus 4 forums
I'm loving my N4 so far
Perhaps too much, because I've been ignoring a problem that I've been facing. My phone drops the mobile network for a few seconds, once in a while.
I was able to find a way to replicate it. I think this happens when the N4 tries to switch on data on 3g or H.
To replicate this,
1) I installed the Network Signal Info app(can't post link here )
2) Next I tried to switch off wifi. As soon as the wifi is disconnected, the phone tries to connect to mobile data network and my phone disconnects completely for a few seconds. See attached screenshot for logs.
Anyone else facing the same issue?
Thanks,
Spaccount
Note that I can't replicate the issue every time. However it does occur very frequently if you first keep it on Wi-Fi for at least 10 minutes.
Thanks.

Steps to replicate
http://www.youtube.com/watch?v=8gRFJdhg160
Note that you need to be on wifi for alteast 10-15 mins before this works..
I tried loading the browser to show the problem(no network).. but I also get an error if I try calling or texting..
Can someone please try to replicate?
I'd like to know if this is an isolated hardware issue. I just finished 2 weeks on my phone.. Hopefully I can get it replaced
How long is mobile data disconnected? You do know that if you are on wifi mobile data is disconnected on all phones, it reconnects when you either turn off wifi or go out of range of the wifi network. It will take a few moments for it to reconnect to mobile data and vice versa, its not an instantaneous reconnect, it can take 10 seconds or a minute or two.

you are correct!
However, during this time period(as in the video), I'm completely cut off. I cannot even send a txt or make a call.
I didn't demo this because I wanted to keep my call list out of the video.

Okay I see what your talking about now, I had removed Network Signal Info off my phone and just reinstalled it. And no my phone doesn't totally drop signal, it drops but not by much when it switches from wifi to mobile data. Are you on stock or custom ROM or Kernel. Its like your radio is turning completely off during the switch to and from wifi, If your on a custom kernel I would suspect it to be the problem. If not then it might be a hardware issue.

Interesting! I'm on t-mobile as well.
I just did a factory reset(the google lady told me to) and I still have the problem.
Is there anyway that you can get hold of a Nexus 4?
Also where are you based out of? I'm in Ohio. Not sure if that matters?

So maybe its a carrier issue, I'm on ST AT&T. You on T-Mobile by chance? I had signal issues when I had them and dropped them in 2 weeks. Could only get a weak signal in my living room and then would get no network detected in my bathroom 10 feet away.
Okay not sure what caused this but I had my phone off for about 20 minutes and when I turned it back on to retest it I got no signal, then turned off wifi and signal came back, then turned off wifi and signal remained the same. Not sure if this effects my ability to send/receive voice or text. Its probably just the phone saving battery by turning off the cell radio.

I am on t-mobile.
However the network is OK around here. It would be great if someone on t-mobile and N4 can try to replicate this.
I had this issue with my previous defective device. If gps was on the mobile connection would crash. My new device does not have this problem.

I had this exact same issue when I first received my Nexus 4. I thought it may had been a faulty sim card, so I replaced that, twice, same result. I went ahead and formated the phone back to stock, same result. Checked and made sure APN settings were correct, same result. Contacted T-Mobile, they reset my phones service and the data in my area, same result. After both I and T-Mobile ran out of ideas I decided to contact Google for a replacement. Turns out it was a faulty antenna and my new device has been working fine since.

Thanks for sharing this!
I just called google and requested a replacement.
The lady said I should get an email in 2 days. I'm on day 13, so I'm cutting it close
Also wanted to add that I ran the same test(as in the video) while on a phone call. It dropped the call and locked me out of the network for 10 seconds just like in the video.
I logged to XDA to report this issue it so annoying and the biggest proplem that my N4 seems to stuck on 3G and won't open internet untill it connects to H
it also happens when connected to E as I dont have 3G coverage over there and it also drop many times
mine seems to cut the radio off for seconds

Based on the following link, this might be a software issue. I know the issue described in the link is not exactly what I experienced, but is similar in some ways:
http://code.google.com/p/android/issues/detail?id=40514
It's supposedly fixed in 4.2.2
Will let you know if I get the update before I RMA(don't want to force the update).

Hi All,
I wanted to share an update. I got my replacement device yesterday. It works just fine.
So this is a hardware issue.
Thanks for all your help with my questions!
Similar problem on Galaxy Nexus
Hi all,
first of all, I know that there's a different forum for the Galaxy Nexus, but since I have a similar problem as discussed here I thought maybe someone can help...
I also have random disconnects from my mobile network, but since I almost never use WLAN it might not be the exact same problem as discussed here, right?
I'm running cm-10.1-20130416-EXPERIMENTAL-maguro-gerrit-35930.zip, and - as I said - my phone randomly disconnects (shows the "no signal" sign in the status bar) and relatively quickly connects back to the mobile network and everything works like normal. The whole reconnection process takes about 5s or so, I don't have to re-enter the PIN or something...
Any ideas how I could figure out what the reason might be?
I have bought my Lg G2 last saturday. I'm still researching the phone and so far it's great except one thing. Problem is when the phone is removed from charging it refuses to establish a data connection. This happened to me twice and every time in the morning after the charging.
Solution is restarting the phone. If not, it just won't connect . When i go to the settings it is turn on, but there are no arrows at the top of the screen and it doesn't work. Otherwise , after the restart it works normally all day. I keep turning it on and of and it works fine.
I think it is a software problem, since I have a network signal, but I'm not sure.
Is anyone having a similar problem?
Thanks

I'm using original usb cable and charger, but with extender , because of the electricity. Phone is from England, and I'm from Serbia .
After the last night charging I had the same problem, but this time I used toggle between Airplane and Data . After that everything worked fine.

Hi, i noticed this too since a couple of days... Trying To figure out what the issue is ( in possession for 2 Weeks)
I can re-establish data connection without reboot by clicking in select automatically in network operators in data /mobile networks settings. So it will reregister on the network.
Guess we need to notify lg about this issue/bug for a fix.
my sprint g2, will drop data connection occasionally when switching from wifi to 3g or from lte to 3g. so i would say there is some kind of real issue here
Same problem after rooting
I'm having the same issue, the data connection drops, mostly after going into stand-by. The problem started to occur a few days later after rooting the LG G2. I have tried the temporary solutions above with succes, but there is no final solution to it. I wonder if the device intentionally starts to brick itself after rooting, I heard the LG G2 has a lot of root checkers (says the noob).
Anyone contacted LG yet? Or tried flashing their device?
I'm having a similar issue with my G2.
After switching off wifi, data won't start.
I have to click search network then it would go on.
Would it be something to do with the modem?
When i had my Samsung gs2, I had problems with random dropouts, then I found a way to flash new modem software and all worked fine with better reception and no dropouts.
I sometimes loose network connection completely (no service) when switching from 3g to 2g or vice versa, no issue with 4g what I've seen.
Though I have this BBS, looks very alarming I must say, does anyone have similar to this:https://db.tt/aKsiw0Xe
https://db.tt/9iMHIZvm
issue fixed
hi after a recent software update (mine was D80210c-HKG-XX, build number JDQ39B,...) the data connection issue is solved for me (also made a LG support case).
But my NFC funtcion stopped working now...
Same here. Ive got this issue after rooting the G2. It cannot connect to mobile data after Im away from wifi connection. Switch airplain mode on and off helps but its annoying even if u have more email account. Another problem after rooting was freezing and restarting phone after mouse connection. But next day was everything fine and its untill today. Have anyone similar issues with custom roms?

I am rooted running Digital Dream on a Verizon VS980 with 12B radio installed. I loose data or go down to 1x all the time. I have to toggle airplane mode or reboot to re-establish 4G connection. Is there something else I can do. I love the phone but the data thing is annoying. Is the antenna really that bad in these phones?

I think and Im almost 100% sure that this must be only software problem, because when the data is runnig, it runs fast and stable. No additional inconvenience.I hope next upgrade (update) will fixt it. However Im really surprising that u have same problem on custom ROM. Im using only airplain mode to switch the data on. I needent to restart device, but it is really really annoying.
Hi everyone, as I wrote before got data connection issue while getting away from wifi. The data cannot start automatic. I found out that it happens only if GSM/ WCDMA /LTE automatic connection is selected in the settings. When I adjust GSM/ WCDMA automatic connection - everything is ok. I was trying automatic switching and runs perfect. So if u dont use LTE, better say if the WCMDA is enought for u, it can be less annoying solution as manualy turn on/ off airplain mode. I hope next update fix this issue at all. Have nice day.

It seems better (still not perfect) I wiped everything including formatting the system partition and re-installed... But thanks for the replay!
Also, I don't have to reboot ... toggleing airplane mode takes care of it, i was just saying reboot is another alternative.

This is definitely a software problem, but I have no idea how to fix it... when I first rooted everything was fine (I was on Malladus). Then I went to CM-based ROM and it was still working well.... then I updated my PRL (*228) and things started going south and I haven't been able to get it back working since.
I'm thinking of going back to Stock and starting over from scratch to see if I can fix the problem.... if anyone has an update on this issue I would greatly appreciate some advice!
potential fix for this issue?
Hi everyone. I had this phone for about 3 months. and the data connection thing has been annoying for me.. So the problem to start off with is at first I dont seem to get LTE at all during the first 2 days. I found online that the 3845#*802# or *#*#4636#*#* got me into adding LTE back into the system but problem is when I reboot. it goes back to WCDMA only or GSM WCDMA. and I lose LTE. But atleast I have LTE when I didnt reboot it. Then I found another problem which is losing data after I used LTE for a while. It won't reconnect until I reboot the phone or SOMETIMES it will return if I go into airplane mode and back. After some long research. I found this to be working for me.
So this is my story of how I got it to work for me
To start off with. This is what I am using
LG G2 D802
Android version 4.4.2
Baseband Version M8974A-AAAANAZM-1.0.190082
Kernel Version 3.4.0
Build KOT49I.D80220b
Software D80220b
My provider is Metropcs so if anyone has other issues with other providers. I don't know if this will help you.
First thing this phone needs is it has to be rooted - that part you do your own research and wont be hard since you are on XDA!!!
Then to get LTE working, you will need to type in 3845#*802# on your phone to get into the hidden menu
LTE-only ---> Modem Settings ---> RAT selection and select GSM / WCDMA / LTE Auto (will display SUCCESS) tap OK
This will give you LTE from the phone but it will not give you this option in your Mobile Networks / Network mode section (Preferred network mode) Atleast it didn't display it for me.
For my phone I had to edit the build.prop file for it to show it in the preferred network mode list.
In the build.prop file. You will have to look for this line and change the 9 to a 11. I've also saw some post about it being not a 9 and have to change to 12 for some networks. ALSO MAKE SURE YOU DO NOT CHANGE IT TO A NUMBER 0. It will crash the phone.
From
ro.telephony.default_network=9
To
ro.telephony.default_network=11
After this I got me LTE connection but issue with the lost of settings after reboot started. So next part helps with the reconnection after reboot. I got this from a post in XDA So give credit to the person that posted this. Sorry if I dont have it handy as I wrote this
- Root
- Install and activate Xposed fw
- Install and activate Intelli3G module
- In build.prop change ro.telephony.default_network=9 from 9 to 11
- Create a Tasker profile of type Event -> System -> Device Boot
- Associate the profile to a new Task of type Misc -> Send Intent
- Configure the task by setting in the "Action" field the value "action.intelli3g.CHANGE_NETWORK_TYPE" and in the first "Extra" field set the value "extra.intelli3g.NETWORK_TYPE:10"
Doing this got my reconnection after reboot fixed. and LAST is the problem of randomly losing data connect until I reboot the phone. and after a long test.. This is my result. The phone lost connection due to trying to connect to LTE with non existing band. I don't know too much about those but from my testing. This is how I made my phone worked and it has been working for the last 2 weeks without any issue.
Go back into the hidden menu with 3845#*802#
LTE-only --> Modem Settings --> LTE Band Selection
Here you will see a Band with a number.
MetroPCS supports band 2, 4, 5 and 12
Since this phone doesnt have 12. You only select 2, 4 and 5 then just push back until the hidden menu closes.
Other providers. I dont know what band that they use. but i am guessing if you only select the bands that company supports. You might not have that issue with losing data anymore.
Please press thanks if this works for you.
My note4 almost always has a white 3g above the service bars. However, even though I still have 3G and there is no change in service bars, periodically my text messages will not send and internet will not work. Keep in mind that my phone constantly says it is connected to 3G. It also happens that the signal bars disappear. After reboot both are OK. *
I do not have any malicious*apps*and my phone is not rooted. Have messed with network settings and have seen no change.
And YES my mobile data is turned on.
Any help is appreciated!
I have the same problem, right now I am trying to figure out if it's software or hardware related...
I would hazard a guess that it is sim card related.
Sent from my SM-N910F
I changed my SIM card, same problem.
What are your APN settings? What geo area are you in?
I am from Romania. My APN settings are default from the provider (Orange).

You got your phone from Orange? It never happened to you that it looks like the phone has signal, but in fact the signal froze and I cannot make a call or to be called. After a restart it's ok for a while. Also if I turn mobile data off is ok.

I got it from cel.ro. A couple of times it took a few seconds to start dialing, but I had no real problems yet.

If have exactly the same issue !!!!
Start with full signal strength and going down to the lowest strength and minutes later no signal !!!
Reboot or Airplane mode can undo this, but the cycle starts allover: Full strength, less strength and no signal.
Tried with 3 different carriers !!
And 2 Note 4's !!
I have the Snapdragon version SM-N910F
What is going on ??
Have this issue with my exynos variant in australia its imported and full 3g signal and slow or no data throughout and sometimes h+ even g or nothing
Next week samsung will come to me and bring my phone to their service and will check whats going on. Anyway I think it's more like hardware issue than software.
I have the same issue with exynos variant I bought the fone from the official dealer in my country,
My data service was not working at all.
I got it working by going to mobile network and choosing WCDMA/GSM option instead of LTE/WCDMA/GSM. although now i cannot get 4g but at least the data is working on H or H+
I think its software as a few people have had this issue both variants also
Same problem here, Exynos factory unlocked SM-N910H. All of a sudden I look at my phone and I discover it's showing "Emergency calls only", sometimes H or H+ but no internet. A reboot OR Airplane mode OFF and then ON will solve both problems. That's ridiculous... I've literally tried everything, factory reset, changed sim, messed with the APN settings. I've had this problem since day 1, even before I rooted it. Darn this, I never had any problems with my HTC One X, and I am using it ATM until Samsung come up wit a fix with an update or something. I hope it's not hardware related as my Knox warranty is void 0x1. :crying:
The same issue happened to me. I have 910c variant from Lithuania. A week ago phone started to lose 4G and after few minutes "no signal". Few reboots and it is working again, but after some minutes there is no signal. What I did notice is that there was no signal problem in my city centre where 4G signal is very strong, but when I did some speed test there, it was only ~2-3mbit (before this problem it was ~50-60)... Unfortunately I did not test this issue by turning off 4G. I did deliver my phone to warranty service 5 days ago and they send phone to Latvia to do 4G tests. I refused to repair my phone and demanded to get new phone. Waiting for the answer
Also rooted my phone so no warranty for me. Changed carriers today and they are doing upgrades so stuck with useless service :/ but i think either it's something to do with root or software i dont think its hardware

Fuxas plz reply to.this thread when you hear back thanks
I dont think it is software, because I tried factory reset and it did not help.. Of course, when I get the results I will share them here.
If anything it's NOT the root because I am having this issue before I ever rooted it. My best guess it's the software and I've researched a lot about this problem, seems it's specifically related to some samsung devices and not only the Note 4.
Yup its a samsung problem and hopefully it gets rectified
Don't think it's same issue as ppl lte issue but my s10+ 1tb doesn't connect to the mobile data when u are out of wifi range. I have to either reset the phone ornl on and off airplane mode to get the data back. Seem to work if I manually disconnect the wifi rather than let it out of range.. seem to only happened after last 2 updates. Phone was purchased from Samsung on Rogers Canadian firmware anyone else?

Im seeing the same exact thing with my 1tb pre order purchase. Bought directly from Samsung for Verizon. I also notice terribly slow download upload speeds(4gb down/2 GB upload) when in restart the phone it will go back to 100gb+ down for a while then get stuck at 4gb again. I've factory reset the phone and odined back to asd7... still the same. I had Verizon give me a new sim and do their provisioning on their end but no improvement.
I hope its not the same hardware issue others are facing.
I just sent mine in for repair. Mine would work only on LTE band 12. If it connected to bands 2 or 4 I couldn't get text, mms, calls or the internet. It looked like it was working until I tried to do something. I downloaded Signal Spy and it showed me what band I was on. Once I figured out the bands it dint work on I had to go into the service menu and trurn them off. No more issue except data speeds were so slow! My phone was manufactured in February so I think that has something to do with it.
It's funny, Samsung kept saying it's the network and an update was coming to fix it. It never came. I even switched networks and the same issue.
