Connectivity Issues

Anyone else having connectivity issues with this phone? Just seems to disconnect from the network a ton.
I heard there was a rumor of 4.0.3 coming out soon from the Verizon rep. Can anyone confirm that?

The rep doesn't know anything more than you can read here.. 4.0.3 was halted for the nexus s so I doubt we will sew it soon. Try a new radio

I have flashed 4.0.3 to mine and the radio is the latest gsm version. Not much has changed and it still has poor cell reception.

Like seriously. This phone is great when it works. But thats only half the time. The other half I cant text or make a phone call. Its not just a lack of a few bars, its NO SERVICE at all...I'm not sure what gives here.
EDIT** Went to the Verizon store and swapped out my phone for another one. Apparently it was the phone itself that had issues. This new one works great.

Phone dropping bars (Canada)

Phone is dropping bars like every hour or 2 its really annoying I'm with mobilicity and with ugkL1 baseband. Any recommendation what to do?

What do you mean by "dropping bars"? Phones gain and lose bars depending on signal strength. Unless you mean it's dropping right off the network?

Ya 0 bar and no service and it says like that for hour sometimes till I reboot

Are you a new customer to Mobilicity? If not, what phone did you use with Mobilicity?

Try putting a different SIM card with a different provider and see if the phone is still losing signal.

I too experienced this issue. I am on the TELUS network with a Galaxy Nexus (as of the 20th) and have noticed my data and signal would drop quite often. So I tried doing the System update to 4.0.2 and had the exact same problem with modem KL1. So at this point I tried flashing a Android Revolution ROM and that didn't fix it. Finally, I installed the AOSP Kang Project ROM with Baseband XXKK6 and now I have no problems at all. Data works as it should, and my signal stays in the green almost all day (except for when I'm at home, but that's because I live in a Basement Suite).
Give that a try!

I have the same issue.
And so does the people in this thread:

Same fix for me and my wife worked. Flashed Kk6 radio

That's a lot of complaints on that site. Could this be a software issue or bad radio on Samsung's part?

Been thru two phones like this. First one was good for about a day then started playing up. After 3 days it wouldn't connect at all. Sent back for repair, still waiting to get it back but they claim it "should" be fixed with a new ROM - I tried all the available ROMs and radios at the time and none worked for me.
Got another GN while the first was being repaired, lasted 3 weeks and started doing the same thing. This one wasn't rooted, left untouched. It would connect in some places but would drop off the network enough to make the phone unreliable. Sent that one back as well, they're saying its a hardware issue with the internal antenna.
Both were different builds from different places too but the faults behaved the same. I'm waiting to get them both back, will be interesting to see if the software or hardware fix lasts longer... I have no doubt at least one of them will go back again!

Still hoping for a solution to this. Stock galaxy nexus on telus, brand new sim, had this happen. I could literally watch my service go from 5 bars to 0. Go dark grey. then go light grey and slowly creep back up and then go blue again. This process took 15 minutes sometimes. In Calgary, where there should be 0 signal issues.
I've since tried every baseband available, none seemed to solve this.
I've noticed the signal quality in general though is fairly weak. I work in Oil and Gas on remote locations. My coworker has a stock iPhone 4s. His phone consistently gets more bars than mine. I can't even send texts sometimes, and he'll be on the phone talking. I'm jealous.

Phone dropping signal all every 15mins

This is really starting to get annoying.. my signal just seem to drop every 15mins. And my phone jump from 3g to H probly every 2secs. And yes I have full bars

I had that problem with losing signal every 15 minutes when I first got my phone. I reflashed the XXKK6 radio in recovery and it fixed it. I'm not sure why that fixed the problem, as that was the same radio I had on my phone, but it work. There is a thread in Development I think that has all the radios in a recovery flashable friendly format.
As far as switching from 3G to H, that is pretty annoying, but I think it's more of a network thing. Most Android phones will just show an H or 4G whether it's in UMTS or HSPA, so you don't see the change. The Nexus shows what you are actually on.

same here. I flashed my radio many times but nothing fixed it.
That´s the only big issue with my GN and it´s rly annoying.
How is it possible, if I have full signal at home (same place) and after some minutes it drop to 1 bar or 0? Something switch of or what ever.

when it drops signal does it still show signal strength? or bars up there?
i was having the same issue where it would drop data, but it showed the bars there. What i did to resolve it was up the min cpu to 700mhz in setcpu and it resolved my issue, i no longer have data drops.

I did the 700mhz and that made it drop every 2 mins lol. Seriously
I just flash the KK6 baseband it seem all good now. It been 3 hours not signal drop

i had the same problem with XXKK1, when it switches fom 2g-3g sometimes it would hang and give me no reception. flashing UGKL1 solved the problem.

I would try flashing a new radio and if that does not work I'd return the phone for another one. That isn't normal behavior.

Had the same problem on roman's rom, at times it was way more frequent and would dump wifi as well; which was understandably unacceptable due to my use of native voip/sip.
Went back to a CM9 nightly after the experiment yesterday of build 27 and everything is better.
iirc, was on kk6.

I am on AOKP build 27 and just started to see my data randomly stop working but my bars still show and so does my 4G icon. You would also see the data arrows working. I was on 4.0.2 radio and upgrade to 4.0.4 radio to see if that would fix it but didn't seem to.
So has anyone had this happen to them and do they think it was Rom related? My 4G signal sticks so I do not have an issue of signal dropping. When this happens only a reboot gets my actual data back. It is like the Epic Touch 4G LOS issue we had but it still shows data instead of giving you the zero with the line in it.

This has been happening to me on AOKP 27 as well. I've never had this problem before on any other AOKP rom. Hmm, think I might flash another modem then flash back to KK6 to see if it helps.

I just flashed CM9. Going to see if it is the Roms fault.

Did you your phone come with the XXKK1 radio or did you flash it?
If it's the stock radio, then it means your GNEX was imported from Europe.
I had a European GNEX with problems just like you described. I tried flashing all radios available here in the forums but it did not solve the problem, my google voice mailbox would get a lot of messages due to my phone being out of reach. Long story short, I lost that phone in an unfortunate event. I bought another GNEX, this time a Canadian import one. It came with UGKL1 radio out of the box and never flashed any other radios because it's been working flawlessly in terms of signal strength.
I'm not saying it's a generic problem. But that is what I experienced.
I suggest you try flashing a north-american baseband, one that starts with UG and hope your case is different than mine.

If its its not too much of a headache take it back. My wife's had the same issue which they tried to fix with a sim card which didn't work so I got a replacement and its now is just like mine....spot on. Fyi my buddy had to take two back with the same issue. Good luck man.
Sent from my Galaxy Nexus using XDA

Anyone fix this? Mine will just stop having a data connection. It says that it has one and the bars act as if they are working but it will not download anything. Sometimes I have to reset and other times I can just put it airplane mode and turn it back on and it works. I have actually tried all of the radios so far including the newest one with 4.0.4.
Extremely irritating. As far as I know, this happens because it is asleep, because I don't remember it happening while I was using it.

[Q] Weak Signal Issues GT-I9250 GSMH

I have been using the GNex for a couple days and it has been a nightmare.
I have no signal whatsoever in my own house. I used to have Galaxy S II and used it at the same place with no issues. I have tried every single radio available for the GNex and they all seem to fail!
I have also installed custom roms, CM9, AOKP, now using Jelly Bean and i love it but the signal..
Does anyone knows if this has a fix?? Or is just dead faulty phone??
Plz help!

So, gsm model, you on radio LA2? Does it have good network reception elsewhere, or is it just at your home that signal is too weak?
Like the poster before me said, have you tried another sim card? Have you tried placing your current sim card in another phone?
You use stock kernel right? Have you tried a custom kernel with smart reflex activated?

The phone actually gets weak signal and lost of connection everywhere. But since at my house i don't have a GREAT! signal it just vanishes.
The phone was Stock when i bought it and had the Issue it came with XXLA2 Radio and 4.0.4 Lastest ICS Build.
After i noticed the issue i rooted and tried all the radios available and roms with no luck. all leave me with low signal.
I sued to have a GS2 and had 2 to 3 bars at home so its a huge difference .
Now iam running JB 4.1.1 with latest Radio XXLF1 and same issue,
Something i have noticed is that the phone has Very high dBm... compared to other phones from same Provider.
FYI i live in Puerto Rico and the provider is Claro.

Same problem here with baseband XXLA2 and build IMM76I.
I know there were signal issues with updates from 4.0.2 to 4.0.4 (see here but, if I have understood well, the build IMM76I should have solved that problems.
So the question is: my phone has come out with 4.0.4, XXLA2 and build IMM76I (so already with the fix for signal problems) what could be the problem? Hardware??

Thats what I am afraid off.. I had also XXLA2 and build IMM76I when I bought it, after that i started to install Diff Roms and radios to solve the issue but no luck so far.
I have not seen any issues like this over the internet.. usually with the XXLA2 and build IMM76I everyone is happy so iam afraid this
is just a bad batch of phones.
Witch version do you have and where it has been build. Mine is GT-I9250GSMH from Korea

I'm planning to test some other radio and also intall the JB OTA. I will keep you updated.

Crap! Just updated to 4.1.1 via OTA and the problem is still there! I'm experiencing 10 - 20db less in signal strength than the one I have with a gs2.The baseband now is XXLF1. So I have to assume that is an hw defect and send it to repair? Is anyone experiencing this annoying issue?

I had this happen to a white unlocked GSM Galaxy Nexus i purchased. I ended up just sending it in for a replacement. \o/
Seems to be hardware related.

I wonder If there is a way to fix the phone.. If i just knew what piece of hardware is and if it is worth it... I bought it 2nd Hand and dont think its under warranty. Does some one knows where i can send it for repairs to samsung??

I'm more or less in your same situation. Before sending it to repair I would like to know the signal strength from the ones that are not experiencing this kind of problems (just to compare with mine and for being sure that is my radio with some weird issue).
So can anybody please tell me, in average, which is the signal strength experienced especially in closed spaces (e.g. at home, at office, etc.). I' have a range between -100db and -115db.
PS with your invoice I think that you can ship it directly to a samsung center for repair.

I just sent an email to Samsung support to see what they will do. My phone never goes above -90 and I've had drops in the city where I've never had problems before. My BB sitting right beside my GNex says -77 and the gnex says -95, iphone says like -84... I'm going to see about getting a replacement or something from Samsung.

I have the same Problem ...it´s definately the 4.0.4 ROM ... I sent my GNEX to the support 2 weeks ago and I got it back with an 4.0.1. ROM. But I did the update again . After that I had the signal problem again... and the hotline said to me please don´t update!
I don´t think that it is the Baseband or the Hardware... it must be the ROm or the Kernel.

I don't see anything strange.... You are experiencing exactly my same problems.... I haven't seen any sw solution to this yet... Probably I'm going to send my phone to repair.

Nexus is losing signal all the time

Hey,
back a few months ago an update came out which introduced the issue that the Nexus would loose signal all the time. Then Google released 4.0.3 I think which solved that. But now I'm at 4.1 and I still have that problem. Can you please help me to fix this? Signal is gone like all 5-10 minutes and I can't really make calls or stream stuff properly.
Pleaaase help me out, this is so annoying!

I'm on Verizon Wireless in the US, and I was getting disconnected from 4G every 5-10 minutes. My battery was lasting for around 2 hours before it was below 50%.
I switched the network mode from "CDMA/4G" to "CDMA Only" and I do not have any connection issues anymore. Granted, I don't have 4G speed anymore either, but I almost always have a WiFi connection and I only have a 2GB/month plan right now shared with my wife.
I didn't get my Galaxy Nexus for the network speed though, I got it to upgrade from a HTC Incredible to get the bigger screen and the larger storage.

I would check out this radio thread and flash a different radio. I was able to significantly improve my data speeds on AT&T by changing my radio. Unfortunately, you'll will have to try them out via trial and error to find one that works well for you.
