Drop data issue on Galaxy Nexus

some people say drop data problem on Galaxy Nexus, it is related to radio/baseband issue, a lot of people recommend the following components
Radio/Baseband：
cwm-radio-i9250-xxla2 (latest radio from Google)
Kernel：
franco.Kernel-r158 (best kernel on market)
ROM：
aokp_maguro_build-35 (latest aokp rom)

Just go back to 4.0.2

I have the above combination and it's worse. The radios in my device are going nuts.

How can it be so bad?
I'm like going crazy!!!
Its the worst phone ever !!!!!!!!!!

Was at the Verizon store today and there floor model had no drop issues. Tried mine right next to it and it started to randomly drop. They are sending me a new one and are saying it will be here tomorrow hopefully I don't have the issue after the new one. The tech has a nexus and said he has no issues with his.

i had the same problem, it would drop data even though it showed i had strong signal until i set the min cpu to 700mhz. after i did that i never had any data drop problems
hope that helps

Came here to ask about this. Was wondering why it keeps happening. Was working fine when I was on stock 4.0.4 but since flashing aokp it happens all the time.

I had these issues with aokp and Franco kernel m3. Switched to revolution hd and James Bond kernel. Haven't had a single drop since.

I'm completely stock IMM76I, rooted and I sometimes get data drops.. this happens more frequently when I haven't rebooted my phone for several days. Sometimes the signal letter (H) disappears completely until I turn airplane mode on/off. Other times I see H but there is no data, only a reboot fixes it.
I'm using Tasker to auto-reboot the phone every day at 5AM, but this is gettig really annoying. I wasn't having any issues prior to that IMM76I OTA.

Noticed this was happening only when I was commuting on the highway, my phone loses data connectivity (albeit still showing 'H') and never gets it back until I reboot.
I'll try the set 700MHZ method and report back. But will increasing the min CPU from 350 to 700 hurt battery life a lot?

I'm really hopping they fix this in the next update, it totally ruins the experience of using the phone. You don't know what you'll get half the time.

Based on my exp, you don't lose much battery life. I accidentally left the CPU at minimum 691 MHz and got similar battery life with 307 MHz as my minimum.

If you don't have PRIMELA03* bootloader and I9250XXLA02 radio on ICS 4.0.4 you are going to have these issues. Google even said so!!! ref. http://source.android.com/source/building-devices.html dont blame google or samsung this phone is rock solid when used properly
fyi AOKP is notoriously buggy, every release is

I just noticed I'm on the 4.0.1 bootloader. I'll flash the 4.0.4 one when I get home to see if I can finally get rid of this issue.
I tried flashing radios and RILs and it really hasn't helped...

I had similar issues though mine were mostly when leaving a wifi area my phone would not grab my cell data until I toggled airplane mode on then back off. Later I found out about GetRIL and discovered that most ROMs (due to being based on 4.0.4) have the XXLA02 RIL (Radio Interface Layer) while I was running the UGLC1 radio. GetRIL checks for you and allows you to flash the proper RIL (if rooted with busybox). I flashed the matching UGLC1 RIL and havent had a drop since

u say always the same response to everywhere...but its wrong (PRIMEKL03 doesn't exists..did u noticed?)
the suggested bootloader is the PRIMELA03..that page have just a typo (i asked to jbq and he confirmed the typo, he will update in future that page)
and EVERYONE have the correct PRIMELA03 bootloader
the signal issue is related to some bugs in the 4.0.4 roms
it happens randomly for some people in some network conditions..is like the phone is not able to get the data network...no way to solve this until a next update from google
the people that said "i solved by changing radio/rom/etc", just didnt test long enough to get the same problem again
if u (and of course lot of other people) don't have any network problem, then u are lucky living in a place where the network and ur operator are perfect...end of story
i'm not pessimistic, this phone is perfect, but will be really perfect when they will fix this...i had other android phones before this, and none had this problems...i know everything about radios, apn, networks..but there is nothing i can do to make it working fine ALWAYS..sometimes the mobile network works, sometime there is no way, even after a reboot, only moving temporarly to a different area solve the problem sometimes, even if signal was full bar

As per my previous post I didnt change my Radio but rather matched my Radio to my RIL (Radio Interface Layer). My phone hasnt dropped data in the longest time since I've owned it and shows no signs of ever dropping it (unless of course I lose signal ).

This question has been asked way too many times. I say the same response because it helps people solve this problem. The bootloader and radio configuration needs to be correct at least as a starting point and first step in trouble shooting. you assume everyone has the correct bootloader and radio, now that is just presumptuous. I'm so happy that you know "everything" about radios bootloaders and apns that is righteous! your post was very helpful, a great help thanks so much.

This is actually not true. I was on 4.0.4 but had the 4.0.1 bootloader somehow.
I haven't had a single data drop since flashing the new bootloader with XXLA02. The real test will be tomorrow, when I take my phone into work (big metal building). If I get no data drops at all tomorrow, problem fixed.

Three Uk Signal Dropouts

I no that i am not the only person who has this issue and it is driving me up the wall. for some reason when i loose signal alltogether it wont auto recontect when i come into signal again instead i have to force it to reconect.
At first i put up with this becasue i loved the phone and i thought that three would be doing somthing about it to fix the problem. but as i have recieved no fix i am getting more and more tiered with the phone and im swaying more and more towards the S3.
The only way that i can hold a signal is if i set it so that i am on 3g only which helps but suks becasue there are alot of ares which dont have the 3g signal.
i have also noticed that the phone looses signal when i put it in my pocket so if somone is trying to contact me while i am not actually using my phone its like i might aswell not even own it.
This signal issue is pretty much rendering my phone usless does anyone know of any fixes that i can posibly do i have not applyed any OTAs directly from three but i have unlocked my phne with HTC DEV and have installed the latest stock roms to try and sort it out with the latest euopean radio to no provail.
does anyone have any sugestions for me? a posible fix? news from three or should i just give up on the HOX and switch phones altogether.

Same issue here dude, minus losing signal in my pocket. Also, I have to use the airplane mode and not toggle the network connection to get it to work

There is a thread here http://forum.xda-developers.com/showthread.php?t=1613521 and basically if you dial *#*#4636#*#* choose phone information and change set preferred network type to WCDMA only the problem is solved - for me anyway but only until restart as the setting is reset.

You can make the setting permanent by instead going to "Mobile Network" in Settings, then "Network Mode" and select WCDMA Only. That sticks across reboots.

Im thinking its a htc software issue which will probably get fixed, it didnt happen with my Desire HD with same simcard.

it has been 2 months though and it still hasnt been fixed HTC are taking the piss with this

Also another thing I have noticed is the signal is slightly worse in a case than without.... So mine at work can be hit and miss even more. I am on Three to with the Three firmware.
It has actually been better since I got it back from HTC repair. They seemed to have changed the whole housing and battery in the report for the squeaking and moving lcd screen. Maybe they have done a better job at putting it together than from Taiwan?

Although I didnt have this exact problem with my HOX from Three…. (just had crap signal, would re-connect OK though, but was hard to get from 3g to 2g and back again sometimes) mine just had poor signal everywhere…. so much so, I cancelled the contract. Cost me £500 to get out of it…. but well worth it TBH.
S

I purchased my one x from amazon and got three to swap my sim from my desire to a micro sim. I only get loose network when im at home.
I reported the network drop to them and they got back in touch. They said that there was not a problem with my phone its just the location of my house and the distance away from the mast. After someone from the network team called me they said that we can offer you a "home hub" (for free) which connects to my home router which provides signal in my house. There is always a catch with companies. They wanted me to renew my contract as i have 2 month left. I am not going to renew as i can find cheaper sim only deals.
I guess what im trying to say is that if you have a long contract left with three file a fault online and push for the home hub.
There is no harm in asking.

I have the same problem with Three and at first I was just like ahh I can live with that.
Now its really starting to annoy me no signal indoors what so ever and when I leave the house will not auto connect I have to enter and exit airplane mode for it to pick up a signal again, Ive sent in a complaint will see if they get back to me.

Just a heads up the signal not reconnecting seems fixed in the latest system, custom ROM here http://forum.xda-developers.com/showthread.php?t=1601543

Problems with WIFI, GPS and radio after 2.17 update

A few problems with 2.17 / 4.0.4
After i installed the update 2.17 i notice that my wifi is even worse. I have i good connection with my Dynalink D635 router. So i don't think it is a hardware problem. But wifi works just sometimes. It was the same with 1.29, but al lot beter Now i loses his connection and than it come back, but mostly there is no data-stream at all.
Also the GPS is not working fine anymore. Lost connection a the time. It was working fine with 1.29 .....
The radio (connection with G/3G/H) is also worse. And sometimes he lose my sim-card and even goes into flight-mode??
HTC, i dont know what you are doing over there, but i have to say that this product is absolutly not what i suspected. I waited for the 2.17 to give the product a second chance, but it is even worse

Basic question. Still, have you backed up and tried Factory restore?

recently my phone doesn't read the SIM after a few hours of use. Says there's no SIM.

agree with the first comment. Can't confirm yet WIFI performance but GPS is now really bad. It was working great on 4.0.3 same as WiFi

I used only files from the instalation guide. No other modifications

CUSTOM ROMMERS
Just ensure you have installed the rom correctly, aswell as flashing the right boot.img for 2.17.401.2, then although it seems like a pointless task, please do well to include the command 'fastboot erase cache' before AND after the flash of the boot.img, just to be sure we don't have any kernel bits left behind. You could also go the extra mile and clear the dalvik cache in your custom recovery...
STOCK ROMMERS
You should ensure that your update was successful (check this in settings > about > software information) If the software version is 2.17.XXX.X
Then the update was successful, just double check your radio/baseband is what its supposed to be which is 2.1204.135.20 (i think)

I have a good question: Did you drop the phone recently or otherwise do anything to push the phone case down? It sounds like you crushed all the antenna contacts or your case just isn't seated right.
SIM losing contact would suggest that the SIM pins aren't fitted snugly against the SIM. You can either put tape on the sim to get to to fit more snugly or send it in for warranty repair.

I did not drop the phone, or did something strange with it. The only thing i want from a device that costs € 500,00 is that everything is does work.

I've have experienced a drop in mobile network signal after the 2.17 update. Haven't tested GPS but WiFi seems alright. I have not dropped the phone nor done anything unusual to it, just updated. Before, I had 5 bars/full signal all the time, and when I checked battery stats the network signal indicator throughout the day was green. Now, after the update the indicator is yellow and I have around 1-3 bars if signal.
Also, I'm in Denmark so I got the 1.29.xxx.12 update which was supposed to optimize signal strength. So right now I hope they are working on a similar fix.

The Custom ROMMERS part worked for me.
I had the same Problem. Just checked after a half hour and it still works.
Just try this method

Dear all,
I was using the Lee-droid rom. I switched to insert coin rom 9.xx and even tried the android revolution rom. In both I had the same problem. Using wifi I have almost no data although the signal is strong. It just keeps trying to synchronize like for hours. But for some reason whatsapp conncection works and no problems there, but when it comes to loading the play store it takes ages (5 min. plus). I already searched the internet for solutions but haven't found one. When I use my providers internet, it also just keeps trying to synch (and for some reason never seems to complete??) internet is also really slow and it used to be faster on mobile as wel as wifi. Is anyone else experiencing this?
I am really desperate to get this working, I hope someone can point me in the right direction.
Edit: Confirmed that wifi does drop out sometimes and cant seems to get a signal although im standing right next to the router. But when I have wifi, I have a great connection, but almost no data, only whatsapp seems to work.

I can also confirm taht after the 2.17xxx update wifi is droping a lot. Didn't had that problem on 1.29. Also there are other issues but it will probably be best if I open a new thread or someone else does that, just for the sake that htc will read it and make our phones better

To me, your issues sound like radio related issued, although I could be wrong. You both on custom roms? With custom recoveries? I suggest if 1.29 worked better signal wise that you flash that radio in your custom recovery. That might improve your signal. Its basically different for everyone which radios work the best so basically it's trial and error.
Lemme know how you get on :thumbup:

I'm not sure if it's the same problem but i've been having a strange issue for a while. I believe is started when I began using jellybean roms (Not 100% sure). My phone will work for a day or two with no issues and then I just suddenly lose my gsm/3g connection. Numerous restarts later and if still doesn't work. Can't use it as a phone at all. If I reflash or change the rom, my connection works again for a few days and then then same thing happens. I'm having to reinstall roms every few days to have a working phone. I did have the pogo battery cover on for most of that time. Last time it happened, I removed the cover and I suddenly had a connection. I've left it off since, hoping it was just that but sadly not. Happened again to me just now

Hi, have you flashed any different radios? What's your current software version and does your Wifi drop as well? Or is it just mobile data?

After the 2.17 OTA update, the signal is always medium...but now there r no call drops or loss in signal

sandipbarik said:
I got my 2.17 OTA update last night, immedietly after the update my wifi signal was dropping, which was pretty stable 3 bars before that.
Today morning im getting dropped gsm signal...sometimes its showing no signal...eve a manual signal search gets me no network, omly airplane mode on/off gets the signal back.
I m not unlocked and not rooted...just plain factory stock.
should i unlock it and flash the radio from the 1.29 rom ??

That's up to you, but many users have experienced that some radios work better for different people. 2.17 works ok for me, maybe you should try.

I think i have the same problem, when data On, GPS On he sometimes turn of after i turn in and when put the pin and he try to connect to the carrier turn of again. This only happens now when i flash faux kernel and before with alex-v kernel..

Data "stalling"

I don't really know to describe this problem better. I'm running CM10 (lately AOKP's latest build) with default kernels. I've flashed all the radios and tried a bunch of them in solid LTE coverage, I seem to have the same problem every time, which is the data seems to "stall."
It will show full signal, and then if i click a link, it will sort of just sit there, not really doing anything. Eventually it may load, or i give up in patience. Any one have any ideas?

I am using at&t stock rom and not yet rooted. Even I have the same problem. Tried to disable and enable data from the notification but did not help. But, when I turn on the wifi, and turn off the wifi again, it works fine. When wifi is turned on phone disables the data and try's to connect to wifi or shows the available networks, but I don't connect and I turn off the wifi, phone reconnects to the at&t data again and then it works fine. Not sure why.

I can't even run a speed test because it just sits there. Web pages "load" but wind up stalling. Sometimes they finish, sometimes they don't. I have no idea what's causing it. What modem are you on?

May be a good time to contact your cell phone provider for a replacement.

I was on a cross country road trip running CM9 on my GS3 and I kept running into the same thing. A temporary fix was to reboot the phone. Since I got back, I flashed SlimBean and I haven't seen the issue again.
In my case, I think its the SIM card. I used Google Maps/Navagation on my HTC G2 (using a micro SIM adapter) and my phone got HOT, I mean burn your fingers hot (upwards of 57 degC to 60 degC).
If it happens again I'm going to bring my SIM card back to ATT and have them replace it. I did some googleing and it seems like this is common with the Verizon variants of the GS3.

That's the next step... it means reflashing, and waiting for samsung to fix it though, which sucks a lot.

ive had this same problem and it would piss me off! i found out that busybox was the culprit. i uninstalled busybox and cleard my cache in recovery and all was well once again. if any of yall have busybox installed you may look into my solution.

I recently been having this issue also. But mine is a little bit different. Like my phone will say I am connected to "H" for data but when I load a Page it slightly lags switches to H+ and boom Internet works. When I stall for more then 5 minutes it switches back. I'm not sure if it's some battery conserving feature or what but I have no problem against at.

[Q] need to reboot or toggle airplane mode to regain connection

Hello,
I am running into an issue where I will lose connection after coming off wifi and it seems 4G/3G is not picking up. I must either reboot my phone or toggle airplane mode to regain signal. I've been searching around and I don't think I've found any thread similar...or it's hard for me to pin one down using search terms.
I'm running paranoid 2.16 and lean kernel. Gonna try and flash a radio and see if that helps...but if anybody can point me in the right direction or suggest a few things, I would greatly appreciate it.
Thanks in advance!

Lte or gsm version? Apparently the lte version has reception issues in general.
I used to take the subway to work. When coming out of the train, after losing service while underground, I would on rare occasion have no service while above ground in an area where coverage existed.
This bug existed on every Samsung smartphone I've ever owned (sch-r720 admire, t989 Hercules, and yes the i9250). I'm convinced it must be an android bug.

I'm stock (rooted)/GSM and I'm having this issue since 4.1.2. 4.1.1 was very stable for me. Today it lost it's connection completely to T-Mobile twice, where the status was always connecting even though I had 3 or 4 bars. Additionally, airplane mode would not engage (no symbol in menu) and could not be unselected from the power menu. Only way to fix it for me was to reboot the phone.
Additionally, I received a call today and the phone froze. I could interact with it barely, but couldn't switch apps or get out of the completely black phone screen. I had to unlock the phone to even see anything. After I missed the call, which rang for a long time (still no idea who it was - no logs and T-Mobile only lists connected calls), the screen would not come back on and I had to do a battery pull.
I'm about ready to just say F*** it and reinstall 4.1.1 stock back on this thing. I want my old phone back
Additional notes: The phone is encrypted due to my job requirements.

If restoring your backup cures the issues, then its baseband/radio/rom related. If not, the phone is damaged.
I had an sgs2 t989 which one day decided to lose its data connection. It constantly tried to sync and couldn't. Voice and text worked, but it couldn't get data (even edge). Changing roms didnt fix the issue and I had to exchange it in store.
