[Q] GPS causes all radio to freeze?

sup xda..
I've been experiencing a fault which I couldn't find on any other threads, but if I'm missing it please direct me to it.
First thing's first... I've been running CM10 stable, tried the default radio and various others.
So this is what happens - turn on navigation or maps, and it'll work for a moment, give me directions and locate me. 10-15seconds later, my position on the map has frozen and "GPS signal lost" is muttered. Reception on 4G and any network connection is lost as well. It'll stay out of action for about a minute, then pick it up again, and the whole failure starts over.
As mentioned ive tried various radios, the symptoms are the same.
I've tried a clean slate of CM10, the various nightlies etc to no avail, same problem.
Today I tried RebelROM (02122013.. android 4.1.1) - no issues! So I ask...
Has anyone else had this problem? Why might I be experiencing this on CM and not another ROM?
thanks

No one huh . Oh well I guess I'm one in a million.

MOKEE 4.4.2 Network Issue - GT-P3100

Okay so i have 4.4.2 in my gt-p3100 and am facing continuous network loss.
One second its there and the other second it says no service.
Then it identifies my cell network but shows this -
No Service- TATA DOCOMO
(Tata docomo is my network provider)
This happens usually when i am about to make a call or message or about to recieve a call or message.
The incoming call gets displayed for a split second and then bam..!
The network goes away.
And then again it shows no service and the cycle continues.
Toggling the airplane mode on and off sometimes helps, but mostly i cant get it even after several reboots or sim changes and everything.
I am really annoyed now.
This started only 5-6 days ago.
I completely reformatted this tab and had a fresh install but still it continues.
I have a custom messaging app called 8sms and xposed framework installed although i use just X-Privacy.
Besides i read that moto G users in my region are facing the same issue in their current KitKat version.
Just for reference : https://forums.motorola.com/posts/027c60e48f
Any help is urgently needed, thanks.

Bump...???

I hope this helps.
Clean install ROM. do not restore backup apps first. first log-in through your google account and restore all..
I experience same problem with other roms also slimkat, sensonic, dhollmen. what i did is restore my contacts and apn setting from my google account not from a backup. i hope this helps.

Well i had just cleaned and installed but what i did was let google restore the contacts and apn.
Then i manually restored some apks via app backup and restore.
And then i used Titanium Backup to restore the data in all of them.
Is this the wrong way.?
Thanks btw.

@gangpe well i changed the APN as u said.
But i was playing GTA San Andreas.
And a call came and it rang for a split second and then same..the network goes away.
But it came back automatically.
Still the issue is not solved coz it happens randomly .

Is the apn still there, or did it disappear? I ran into an issue once where the apn did not save for some reason...

Well its still there...
I chose the same name for it too, would that conflict.?
Also randomly it happens when sending/recieving a message too.
I click on send and suddenly it says no service and then the message cannot be sent even after 2-3 reboots. :-/

Bump..
Any one know any solution..?
Its starting to get on my nerves.
Random no service msgs.
And wont get stable unless 2-3 reboots..:-/ :-/

Not sure what to tell you. A few days ago, I had a few weird issues (could not install xposed framework, quick settings panel would not work), so I ended up wiping cache, data, system, and dalvik. After wiping, I re-installed the ROM, and I have been good since.
In my case, there was probably an old setting I had that was causing issues. If you haven't tried wiping those four options, then I would suggest you try wiping/reinstalling.
If you have tried that, not really sure what to say. Sounds like you might need to head back to stock for a while until a later release resolves the issue.

Mmmm...the thing u are telling is a case of wrong dirty flash of a rom, i mean u must have flashed a previous version rom without wiping over other rom version.
I have faced this too..but the thing i was facing seems to have gone now on current latest release.
Dont know but i did not fixed permissions from TWRP this time after OTA and now the issue hasnt surfaced since 24 hours.
Maybe i'l wait some more and check and report back here.
Thanks anyways.

Now i m gonna pull my hairs out..!!!!
Wtf is this sorcery.. I was watching a vid on MX player and again the no network issue started happening as soon as a call came....!
This MX player is the culprit i think..usually while watching vids this happens...

Same issue for me on p5100, it happens both on Dhollmen and Mokee.
I don't have MX player installed.
Often happens when watching videos, but I'm not sure if it happens ONLY WHEN watching videos.
However, no further way out than rebooting.

Well i am facing this randomly..but usually while mx player is on.
I cant seem to find any solution to this.
In rare cases i need 2-3 reboots to fix this.

M soo very disappointed guys.
Have not a single site as great as xda and not many people are even looking at our problem.
I generalized the problem to most full screen apps.
And it happens usually while pausing the app and flicking down the status bar and doing some multitasking from there or pressing the home button.
Anyone....???

Or should i just try Omni Rom.?
Maybe Mokee has this bug..?

If you try Omni Rom, I really appreciate if you let me known the results in any case, since I have no free time and currently I cannot flash this rom

Okay mate, i'l flash that in about a week as my exams are going on.
Omni has just this battery drain issue.
It seems no one knows about the problem we are facing on mokee.

@loboz well i flashed omni and its feature packed..
No issues till now, a little different from mokee and you'l be glad you did as mokee's OTA are dead too..
Satisfied with omni..

Blaze Signal Keeps Going Out Problem(On Any ROM!)

So here's my issue, my Galaxy S Blaze has been switched from ROM to ROM constantly, I have seen ROMS with modified build.props, other added features, and a bunch of other tweaks, you name it! I don't know what all those tweaks mean, I have no idea if it could affect the way my phone receives the signal but it got me so frustrated that I kept switching roms until finally then I went back to stock and am no longer am switching to another ROM.
Here's a history of the ROM switching I've made in the past couple of months:
1st - MIUI
2nd- Cyanogenmod
3rd- Gummy ROM
4th- Liquidsmooth ROM
5th- Cyanogenmod
6th- Dirty Unicorns (problems with signal started occurring right about here, and onwards)
7th- Stock ROM (hmm... nope nothing fixed.)
8th- Validus (still no, I didn't like the constant force-closing of many apps)
9th- Gummy ROM (nope, what's worse is my screen kept freezing if I had atleast 2 apps open and I slid down the notification drawer)
10th- Cyanogenmod (well, maybe switching to cyanogenmod will fix it)
11th- Gummy ROM (*sigh* switching back? Nope, still didn't help my signal)
12th- Stock ROM (you would expect it to be fixed right about here, but nope)
So what's up what is the exact problem with my signal? Here's the thing: My signal works! That's a start atleast. However, if I turn on my Wi-Fi while I'm home, I can still call/text people, all of that works. But after maybe 2 hours or so, the signal bar is still there, it's telling me it has signal and it's connected, SOMETIMES it will be empty meaning I have no signal(when I really do). But in reality, I can't receive texts, nor calls, none of that. So how do I fix it? By restarting my phone sadly, that has been the only solution for me for these past 2 months. People have complained to me because I don't answer my phone anymore, well I'm sorry my phone can't receive those calls due to this messed up signal. There are 3 other T-Mobile phones in the house that have no problem! The problem here is with my Blaze phone.
So what if I turn the Wi-Fi off for the whole day and see if it's the main thing causing the issue? Well, I did this. Turns out that the signal stays on longer than when I'm on Wi-Fi but it still goes out. I have switched SIM Cards, I have tried switching my APN: from "epc.tmobile.com" to "fast.t-mobile.com" but the problem appears to happen more quickly on the "epc" one than the "fast" one. Please help me with this, this has been frustrating me a lot lately. I'm not sure if anyone has even had the same exact problem that I'm having, I've searched online but haven't seen a similar problem.
Some of you might say, wow that is a lot of ROMS you've switched to, I'm sure there were more that I missed but that's as of recent. I can install ROMS correctly, I know how to use CWM when installing a .zip and using Odin when it's a .tar(or other supported file extensions). I've factory reset, wiped the cache, the dalvik cache, all before installing a new rom. After installing each rom, I've also factory reset and wiped the cache to make sure no other problems could affect the way the rom would work. Hopefully I did the procedure right, thanks for anyone who's willing to help me!
Right now I am running:
Baseband Version:
T769UVLH5
Kernel Version:
3.0.8-perf-T769UVLH5-CL990184

SMP PREEMPT Fri Aug 17 15:12:14 KST 2012
Android Version:
4.0.4
Another Issue is that I can't even transfer files to and from my phone when connected to my computer! This is another big issue, here are some images:
http :// i.imgur.com/xx699ss.png
http :// i.imgur.com/1wRzJpX.png
Here's what happens when I turn Wi-Fi Calling on but maybe it's just a built-in function that I forgot it had and it's probably normal:

By the way, sorry for the links just copy and paste them in a browser to and remove the spaces between the http :// and i.imgur, thanks! Unfortunately, I can't post links until I reach 10 posts. If the links don't work for you, I've also provided attachments.
Many thanks!!!

That last picture does show the proper function of Wi-Fi calling however I don't know what to say about the rest of your problems.

There are two things I would recommend trying...
1. Use Blackhole System Wipe
I know you've been following all the proper steps in CWM (and I would say to keep doing so), but I've added using Blackhole, in addition to the first steps, and I always get great system performance on my phone, and my parent's phones (I put them on ProvisionMod after stock was being stupid). It works well for pre installation for ANY ROM and helps prevent pesky issues. However, chances are, your issue is baseband related and this probably won't solve it... But still! You never know! It's worth a shot!
2. Reroot your phone
I know this will be annoying and pesky... but sometimes the process goes wrong from the beginning and starts giving issues later on... When I first rooted my mom's blaze, something went wrong, despite my following all the directions, and one of her partitions was completely disabled, no matter the ROM. I redid the process of rooting her phone (not from GB though... From the ICS stock) and fixed the issue instantly! I would try these two steps first and see if they do anything! Good luck!

[Q] WiFi and BT Issues with Peregrine Carbon-ROM

Hi, i was happy seeing that the dev of the CM/Carbon/Slim-Roms didn't just stop but moved from the old original shabbypenguin-thread to xda
the latest Carbon-Build ( CARBON-KK-NIGHTLY-20140825-0209-peregrine.zip ) finally works for the most part on my side, pretty happy with that.
unfortunately 2 things aren't and i wanted to see if anyone else has this issues or has some idea to solve them
first one is, that WiFi won't connect to all networks - at home on a netgear-repeater everything is fine - in the office it won't connect to D-Link and TP-Link routers.
the other, more troubling issue is that bluetooth isn't working as it should - as long as no device is connected, everything is fine, but as soon as it connects to my car-system (MB C-Class w204 without command if that makes any difference ) the bluetooth-process stops, reconnects, stops again and so on...with my laptop everything seems to be working fine and i think the first drive after coupling also worked fine - any idea what can be the cause of this? never had this kind of problem before, be it stock or older unofficial CM-Builds etc...
i'm refering to this thread btw: http://forum.xda-developers.com/moto-g/4g-development/rom-carbonrom-kitkat-t2847887

*push* nobody got any ideas? i would post it in the appropriate thread (especially since this rom is still only nightly) as a potential bug report, but as a new user i'm not able to :/

just another push...somebody must have any idea on what i can try to either solve or at least track down the cause of the issue(s)
sure enough, the BT-issue is worse..
tried the newest build (dirty update and after that clean flash), but still no luck

The WiFi bug is a known issue since early August. It affects almost every Moto device (G, G 4G, X and defy?) it's reported several times to CM-s bug tracking system, but nobody cares... You can use custom kernels. Maybe they aren't affected.
I don't know anything about the BT bug.

i found some posts about people having the same kind of wifi-issue, but it is good to know, that the devs are aware and - kind of - working on it
the BT-thingy is driving me insane though...fiddled around a bit, stopping BT-Related processes etc...this somehow did something...my phone now connects and stays connected, i can make phone calls...but the contact list is incomplete - only 3 random contacts are displayed on the car system
haven't rebooted since then, i kind of fear that rebooting will bring back the issue :/

BT still working after reboot, so it seems my "fix" is permanent...must have something to do with deleting the BT-data/cache while process was killed i would think - in case someone else also encounters this problem
still can't acces all my contacts from Car-system though :/

Most nights roms have a lot of issues and it is pretty hard to stay aware all of bugs. Why don't you try something more stable like Pac Man RC or some. Sometimes a different kernel will help sometimes it's the opposite.

Well, i'd rather use a stable version for sure...
sadly, i didn't know about falcon<->peregrine, so i thought i can use all the Moto G roms with my xt1039...
and to this date there are no stable roms for peregrine that i am aware of - an old unofficial CM-Build worked pretty good for me, but CM unfortunatley doesn't offer all the features i want - carbon covers pretty much most of it, so i'm hoping that it will be "bugfree" soon enough ^^

All AOSP rom uses the CM device tree and kernel as a base, so the low level kernel bugs are the same.. Also the last "stable" CM for falcon is dated back to April, so you didn't lose anything with peregrine...

Just in case anyone encounters the same Issues:
with CARBON-KK-NIGHTLY-20140922-0414-peregrine the BT-Problems seem to be resolved, connection works and the contacts are accessible from the car.
WiFi still has problems with dhcp, but as stated, devs are aware of that :good:

bad news: flashed to CARBON-KK-NIGHTLY-20141103-0939-peregrine and the BT-issue is back as in the beginning - com.andoird.bluetooth stops working - but only following the first connect -.-
interestingly going back to my pre-flash-backup didn't resolve the issue (doesn't matter if i just restore or wipe prior to that...but after flashing/restoring the first connect works perfectly)...perhaps that leads to some ideas about the cause?
was just trying to get it to work like the other time by stopping/deleting data of com.andoird.bluetooth, but didn't work this time

ok, figured it out again, this time i'll post my steps in case anyone ever encounters similar issues (and for my future reference in case i encounter them again, too )
1) unpair
2)switch off bluetooth
3) stop com.android.bluetooth in "apps"
4) delete data of com.android.bluetooth
5) reboot
6) pair
7) unpair
8) delete data of com.android.bluetooth
9) pair
10) reboot
at least these are the steps i did and it seems to be working now, again

Intermittent Data/Cell -Exclamation Mark in Signal Indicator

This happens on every Lollipop ROM I have flashed, no problems on 4.4 ROMS. I do clean installs, do not restore anything from Tibackup. So basically what happens is I will randomly but very frequently lose all data and cell service. Like once every three minutes frequently. It only lasts about 5 seconds at a time. The signal bar triangle will have an exclamation mark in it (see attached example). I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option. I have read some threads about this exact same thing happening on Nexus 5 after Lollipop update but they are old and it seems to have been fixed with an update. Does anyone have any ideas about what is going on? I'm on TMO in the US and like I said, it ONLY happens on Lollipop ROMs it does not happen of Kitkat.
I read this as sort of an explanation as to why but nothing as to how to fix it. It is driving me insane.

I'm in the same boat, I cant make calls with hangouts or with Dialer or it will disconnect. I haven't seen a solution yet. I've tried every ROM I can, but it keeps crashing. drives me up a wall. I want to logcat it, but having issues while at work.

Only discussion about this I have seen is in the Nexus 5 forums, nothing in OPO

Any insight to this would be greatly appreciated.

Come on guys, am I really the only one with this issue?

You're not alone, I have this as well but I don't get the exclamation mark but instead the triangle appears completely empty, as if I have no signal at all.

anyone know a way to fix this awell? i flashed the new lolipop alpha modem and still same thing if not worse

The only time this has happened to me is when I toggle Wi-Fi. It for this every time, but have no data issues otherwise. Seems to be when switching between ip addresses. Are you possibly between towers or roaming on another network? May be the issue, but I can't say for sure. Running the lollipop rom exodus, no issues at all.
EDIT: also what baseband are you guys on? I thought I saw something similar and someone flashed a test baseband and it fixed whatever issue they were having. Link coming shortly.
EDIT 2: just now noticed the list above mine about the alpha modem and it not working for them. If anyone else needs to try however, link is http://forum.xda-developers.com/sho... work for some and not others.
from the one+

Does anyone know if we can flash the CM11S modem on CM12?

Go to Settings -> More - > Mobile Networks. Make sure all the items are set correctly.

In OP "I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option."

Same issue here. Running SlimSaber using alpha radio.

Same problem on two OPOs here, both running Temasek CM12

Anyone found a solution yet?
I have the same issue on CM12, BlissPop and Validus ROMS.
Strangely I do NOT have the issue on Euphoria.
Think it happened after I flashed the Alpha L modem.
Tried flashing an older CM11S modem, but no luck...

Hi,
Sorry for the noob answer but anybody tried settings>mobile networks>preferred network type and set it to 3G? I flashed a new rom from stock CM and noticed that I was experiencing signal trouble, I checked my status and the signal detected is LTE so I changed my network to 3G and network signal improved. Downside is that you cant use LTE (but thats ok for me since here in our country, LTE signal is still kind of limited)

Zino same for me. Ever find a fix or a rom that doesn't do this?

OP here, it's strange that all of us have this issue, the same issue that came up on the Nexus 5 thread when L was first released but know one else seems to have any knowledge of it. I am almost certain it doesn't have to do with our carriers but rather something software related.

I'm also suffering from this issue, until now the only way I knew how to fix it was to wipe the cache in recovery which takes ages!

got the same problem :<

I have a similar issue. I use t mobile in the USA and LTE works, H+ works, but 3g shows signal and won't load anything. No idea how to fix it.
