Wow, this is ridiculous and why is this happening?

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?

maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.

When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Thanks, let me try it out.
Where is the network changing option to GSM only in ICS?
Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?

Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available

Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!

:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location

I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".

I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).

If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.

Galaxy S5 3G to LTE Hand Off Issues

Hello,
I am casting a broad net on the internet here to get a consensus with what is going on with the LTE problem many are having with their S5''s
Does anyone NOT have an issue with their phone going from 3G to LTE then back again. A lot of people (including myself) have to toggle airplane mode on/off just to pick up LTE. It does not automatically connect for some reason.
For added information, I am in a non LTE launched city but have been testing by a known LTE tower. when I drive up to it the S5 will not switch over to LTE. When I toggle airplane mode it works.
I guess long story short. Is there anyone out there that does not have this issue?
Thanks a ton for any information!

I don't have that problem I always have LTE unless I travel far out of the city which is normal with all the LTE phones I have had.

Think it's an issue with your provider, I've tried LTE/3G with four different providers here in Denmark without any problems.

Could be an issue with the SIM.
Also, which version of the S5 do you have? EU, US, Asia, etc? BRanded? Unbranded?

I do not believe it is actively searching for a LTE signal all the time. It takes a min or two for my phone to pick up a LTE signal once I'm in a known coverage area. I've done the airplane mode toggle before as well..... It forces the signal search right away.

I'm sorry I should have mentioned that I am on sprint. I will be going into a launched LTE city here today and will do more testing.

Yeah I'm a Sprint user too. All of my Sprint LTE devices have behaved similarly. It takes a few minutes of being in a known LTE coverage area before my phones (both IOS and Android) would connect. Its because the radio isn't actively searching all the time.... I'm not sure what the actual search interval is, but it's not constant. And again my Iphones behaved just the same as my current S5.
My Evo 4G was constantly searching for a wimax signal when I wasnt in a coverage area.... it really sapped the battery because that radio was always on the hunt for that wimax signal.

Got no issues of this kind

im on tmobile im having the same issue ,never had this problem with my s3lte

I don't have this issue, however on one occasion at work I lost 4g signal which is usually at 2 bars, and it sat there and didnt connect to 4g again until I did airplane mode, then it came back fine. But this is the one and only time I have had the issue.

this is a sprint issue
you need to wait until they finialy decide to update their towers to handle the new triband phones, they claim they will be done with all the updates by the middle of the summer, i got sick out their sub-par coverage and took all my lines over to verizon... no regrets
details about their issues are here, it is a long read but good:

S5 LTE Hand-off Loss of Signal
I'm a Sprint customer on Long Island, New York and I've been having the issues as well. I had to deactivate the S5 because it would lose data and even phone service sporadically without any warning. Sprint's solution is to go into Airplane mode for 5 minutes then back, but that's 5 minutes without service after noticing that the service is gone (and losing how many calls/messages). My girlfriend has one too and probably misses about half her calls (and texts come in late constantly) What happens in an emergency? I recently blogged about this. Isn't Sprint opening themselves up to liability by selling the phones while these issues are known internally?

Im in Denmark too, and i have the problem with Telenor, but did not have the problem with Telia, unfortunately i have to stay with telenor, work phone

You didn't do a forum search or you would already know that it doesn't affect everyone. There are myriad threads about this and the concensus is that it is carrier dependent.
Open a support ticket with your carrier. Also, the 4.4.3 update is said to address this bug, so that is something that you might want to look into.
.

Just a little update, put on download booster, and after that no problems whit disconnect from network, will see later when i leave home to see what happens then.

Roaming on VZW after CM13

When I first started using CM13 my signal went to roaming when I know I should have service. I have data roaming off and I've checked to make sure I'm not getting charged for roaming and I'm not. My phone works as it should and I can do everything I need still so I was hoping it would be fixed in one of the new updates. I am on the newest nightly build as of this morning and the R above my signal is still there, just wondering if anyone else is having this problem or know the cause?

I have the same issue on my Nexus 6

Same issue here. Nexus 6 Verizon, just switched to CM13 and I'm stuck on roaming - so far I've tried airplane mode for a minute or two, turning the data off and on, turning the phone off and on, and chatting with Verizon support in case they could do anything remotely. The one thing I haven't done though is try putting another sim card into my phone to see if I could divine any information that way.
Any help would be appreciated.

So after trying just about everything I decided to cave in and jump back to CM12. It was there that I noticed a key difference:
CM12's settings -> mobile network settings, has the following sub-options:
Data Roaming on/off
Preferred Network Type
Enhanced 4G LTE Mode on/off
System select
Access Point Names
CM13 (nightly #2) only has:
Data Roaming
Preferred Network Type
System Select
...while in all honesty I don't know what it all means except to say that it appears to be missing some features of the CM12 nightly I'm using on my Nexus 6 on Verizon. I guess I'll try back in a week or three to see if everything is working fine.

For whatever reason I had LTE pop up for like 2 seconds but went back to R and has stayed since..

Oxygen 9.0.5, Losing Data Signal Often

Pretty self-explanatory from the title, unlocked 6T with Oxygen 9.0 .5, constantly losing data signal, sometimes reconnecting in 5 or 10 seconds, sometimes taking longer or one time even requiring a reboot. Anybody noticed this, known issue?
Edit: on T-Mobile with T-Mobile SIM, APN looks all good, it auto-loads when you put the Sim in.

I've only seen my OP6T (unlocked) lose TMo signal once. It was when I was using the Switch app to migrate apps/data from my Pixel 2 XL. I had to reboot in order to get it to reconnect. But that was on 9.0.4. No issues since that one time and no issues on 9.0.5.

Pretty much what this guy said. I'm also on T-Mobile. Used phone out and about today after update works fine.
Check your APNs and worse can just network reset.

Thanks to both of you, I did the network reset to default so I will see if that helps. Thanks again. The APN seems to Auto load when I pop in my T-Mobile SIM, so it's kind of greyed out but the settings look fine from what I remember of the T-Mobile APN.
Update: tried multiple Network resets, the issue persists. I believe my phone is going back, it's happening every 5 to 10 minutes when I'm using the phone.

I'm still getting lots of signal drops even though I've tried so many different things. The LTE Discovery app seems to be showing that I'm usually on t-mobile LTE band 4, but when the connection drops out and reconnects after 5 seconds or so, then I'm on band 2. So it's been suggested that it might be network congestion with all the new subscribers. But this doesn't seem to happen on my T-Mobile branded V30, or at least I haven't noticed it or it doesn't show in the status bar icon. So, I still don't know whether to keep the phone but chances are I guess I will.
Edit: this post failed because of a signal drop and I had to wait 15 seconds before I could get it to go through.

No internet/data during phone calls

On Sprint's Network, unlocked bootloader & critical partitions. Anytime I even receive a notification for a phone call coming in, my LTE is dropped instantly. Deny or hang up the call, it comes back. I've read that Sprint's 3G can't handle voice and data at the same time, but this is 4G. Wifi is also completely useless on this phone as it stays connected for about 60 seconds tops.
Tried doing a complete wipe and reset to both Pie stable and Q beta 6, same exact thing. Tried all the network options in settings and nothing.
Does anyone with Sprint have working LTE during a phone call? I'm trying to figure out if it's a **** copy I got from Amazon, or the network. Thanks.

I have the issue. I also can't get LTE+ to work either. I'm on Boost, but they use Sprint. All stock roms and I can't get 4G at all on custom roms. I bought mine directly from Essential.

I can't say anything about Sprint, but VoLte on Verizon behaves the same way for me on Q beta 6. If the radio cycles for any reason I lose VoLte even if it shows selected. I have to toggle it in network settings for it to work.
Just curious, if you go into the phone info with *#*#4636#*#*, does it show that VoLte is provisioned?

It's grayed out for me. I can't enable it. Maybe calling Boost customer service might result in fixing it.
