I've had my Nexus S for about 7 months now. It was working fine until a month or two ago, when I'm at home and I would lose 3G signal. The bars will turn gray completely, but full bars still.
I can fix this by either turning off Airplane Mode On/Off or rebooting the phone.
I've flashed the newest radio (KJ1) for the I9023A, but no help.
I'm sure that it's not the tower that's at fault because I've been using my Nexus One for a few days and I don't lose signal at all. Also, this happens not only at home but other locations as well (work, restaurants, etc.).
Please check my signature for the ROM and Kernel that I'm using.
Would flashing a new ROM/kernel help? Or is the radio faulty?
Thanks
Bump.

Definitely try a different kernel, like Trinity 132 (@ 1000 MHz).

i have a variation on the data network problems, not as annoying as reboots,
but getting close.
normally i am on GSM only, as my data needs are low and it extends
battery life. for hours, everything is dandy. then i notice that
the "G" icon and the signal bar are not blue anymore (stock theme)
but grey. 'settings' say i am still data "connected", but in fact
data connection is out (the operating system thinks there is
data connection, browsers and mail clients keep spinning and
trying until timeout).
turning on and off wifi makes the phone try to connect to the data
network again. sometimes this works, but more often that not, i have
to switch to 3G mode for this to work, and sometimes even that does
not help, and i have to go airplane mode to turn the radio on and off
completely. otherwise it just tries and tries and tries to reconnect,
draining the battery like crazy, and sometimes resulting in these
mysterious reboots others are experiencing as well.
is this the phone or a network problem? (tmobile in the netherlands)
i was on the same network, same SIM with an older LG android phone
and i dont recall having this problem, so i am a bit hesitant
to blame the network for every outage...
should i just send it back for repairs/replacement?
system version: 45.0.74.MB526.Retail.en.DE
baseband: EPU93_U_00.60.00
for a while i will keep the phone in 3G mode to see if the same
problem exists. as my mobile data needs are low, it would be
a shame if i cannot keep it in GSM mode because of this...
I had the same problem couple of months back but since I'm on msginger don't have that enjoying problem anymore.
Ohh and as far as remember it was only when the battery was on maximum save, now I'm using custom and it's fine

i am on custom saving mode. i think that the saving modes, where
the data connection is cut off after some inactivity, just flesh out
the problem more, as trying to connect back to the data network
happens more often then during normal use, when data connection
is kept alive all the time.
since i set the connection mode to 3G or better, i did not have the problem
but that was only a couple of hours ago. sometimes a day goes by
without manifesting itself...
I'm on 2G all the time. And the custom saving still got set up for cutting the data off but i don't seem to have that problem anymore i can check later on if it would still appear on max saving.

so after days, it seems like i cannot reproduce these problems
while on 3G. seems like 2G only for data is not 100% reliable
either because of the phone or the network itself, or both.
pitty.
i m having problems with network reception with the 7.2 CM rom on the defy+.tried the baseband switcher in this link but still little or no reception
http://forum.xda-developers.com/showthread.php?t=1203297
i have been on 3G last couple of days, and no data woes.
however i had a spontaneous reboot, so the reboot problem
is seemingly not only a 2G issue (if it is)..
Hello,
During the past couple of weeks my nexus has been losing its cell signal every few minutes. It's like clockwork. If I completely wipe the room and start from scratch, its fine, but after a few days it always starts to do it again. Has anybody ever seen this? It was doing this on paranoid android, so I decided to leave it and go back to aokp. No luck. Cache wipes do nothing, rebooting it is sometimes a temporary fix. I am not using a custom kernel, and I don't ever flash new radios!
Any ideas? Thanks!

I have similar problem: Signal failure if I charge him.
I had nearly the same issues with my N4! But I don't life in the USA! I'm from Germany...
Over the he last 3 weeks me and my girlfriend lost network signal every 3-5 minutes... First times I was also wondering if that's because of a new rom I flashed or if the baseband doesn't fit with some of my kernel/rom combinations.
After 3 days I recognized that my girlfriend got the also this kind of issues, but she on a galaxy nexus!
So I started searching the Internet if other people have the same problems (especially the same issues but not related the N4)!
So in our case the problem is Vodafone Germany. Vodafone is building a new lte/4G/umts infrastructure and because of this they are shut down some of their network antennas in my area! After switching my phone to a 2g connection most of the problems are gone... And my mobile network speed also! :-\
So try to switch to 2g and see if it's fix your situation!
I get some money back from my provider because of the problems!
But the most important thing is that my N4 is ok!
Same problem as Ümit only losing signal when charging the phone. Does anyone have a potential solution?
This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?
This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.
I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.
Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?
Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?
I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?
I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to
CDMA/LTE/EVDO? Just throwing out ideas

I get this issue all the time & I have to do a battery pull to get my phone working again. Anyone flash a new modem which fixes this? The SGS4 is 10x worse than my HTC EVO 3D was with this issue.

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
Currently using Omni rom and hellscore kernel but I had this problem in all the roms I've tried.
My phone randomly showing H signal instead of H+ and there's no Internet connection sometimes it loses the phone signal completely and the service is not available.
The only way to fix it is rebooting or turning airplane mode on and off.
Been having this problem for a long time and would really appreciate your help.
Do you have any idea what's the cause for this?

H+ only shows up when you are actively using data- it's a feature of fast dormancy. Completely normal.
As for data drops, what exact symptoms are you experiencing?

The H+ symbol turn to H and there's like no connection.
It's just suddenly happens there's no special symptoms.
will install 4.4.3 hope it'll fix it.
will come back in a week and let you know, Thank you.
Hi everyone,
I've had this issue with my D800 for a while now. I've done a full clean install of CM12, following all the proper channels and install procedures.
I live in an area (central California) where I can have LTE one moment and Edge 100 feet later. So there's inconsistency everywhere I go.
When I am in an area with poor signal, my phone with freeze, and then reboot. It's quite annoying and happens approximately 5 times a day.
I put the phone in Airplane mode and try to get the phone to do it again, and it runs perfectly fine. Turn airplane mode off, it starts searching for a signal, then the reboot happens.
I used voltage control in many variations to slow the cpu down and still, it does it.
Does anyone here have any suggestions on what I should do to fix this problem? Has anyone else had this issue? Thanks!!!!
I've also run into this on the LG G2 running Blisspop 4.0 (based on CM).
I had the problem too, but it disappeared a time ago after the fix. Since then only one reboot... (I think 2 weeks ago or so like that)
