G2x Data Issues (No 3G or 4G)

Hello i just picked up the G2X phone today and upon leaving the store the phone had begun to have data issues. Meaning it was not keeping its connection, which left me with no functionality to the internet.

No such issues or complaints on this. Were you on wifi in the store?
Sent from my LG-P999 using XDA Premium App

No, wifi wasn't enabled in the store. As a matter of fact, i actually tried to use the wifi when 4G begun having data issues and was unable to find any networks.

Mine has randomly disconnected from 4G as well, although the status bar still shows it connected. If I restart the phone it comes back on.
I think it may have something to do with toggling on wifi, but it has also happened after just sitting idle for an extended period, and wont come back on.

Well, I think LG should of did a lot more QC before they even though about dropping this phone on the shelves. There is also a lot of little stuff that this phone is just not doing that my optimus T did flawlessly.

I'd have to agree. I'd recommend having your sim card replaced to see if that helps.

Had the same issue. Out was my sim card. I had been using my original card which wasn't compatible with the new technology. Once I put in the new card it was all good.

Interesting ill tell you how i was able to get the phone. I was actually on flex pay the TM rep ported my number to a new line on our family line. Before that happened i was using a different number that wasnt attached to the sim card i am using now and 4G internet was working correctly on that sim card.But, Now that you have stated your issue. i think im going back to the tmobile store and see if they can get a new sim card for me.

So I'm not the only one with the network issue. seems like as soon as I disconnect from wifi I lose network connectivity. I still see my signal but can't access the internet at all. Totally locks up until I reboot. Which is proving to be a pain in the butt.
I'm going to t-mobile today to get a new sim card to see if that changes anything, mine is currently from Oct 28th 2008. The day the G1 was first released. Can't even read the numbers anymore. But to my knowledge the cards haven't changed. Guess I'll see if this fixes the issue.

I get real sluggish results from my g2x, my nexus one ran fine...
I am going to try the sim card and see if that fixes it.

That is the way it is designed. When you have WiFi on, it disables your Cellular data to save power. Hence why the 4G icon disappears.
When you disable WiFi, it has to reenable the Cellular Data. So it takes a sec.
Now if it NEVER comes back then there is a problem. But don't expect it to be instantaneous.

When I have wifi on, the 4g icon still comes on and off constantly. When wifi is off, 4g icon still blinks on then off constantly. Still don't have any data. New sim card didn't help either. I go through a battery in about 4 hours because its constantly connecting and disconnecting to the network.
LG sucks.

I'm pretty much convinced this is related to Wifi calling. Try disabling that (this will also help your battery life something serious - take a look at devices logs when wifi calling is enabled.)

When I upgraded my G1 to my G2x, they said they had to give me a new SIM card because the old one won't do 4G. According to the sales person I spoke with, you will need a new SIM card.

Can you keep your old number with a new sim card? My sim card is the same one from my first phone, nokia 3390

I'm having the same problem.. I used a new sim card and I still can't get any 3G or 4g for that matter.. Any ideas or is my phone defective??

i believe all the phones come with the setting already on GSM Only. YOU NEED TO CHANGE IT TO GSM-WCDMA AND YOU WILL GET YOUR 4G SERVICE TRUST ME IT WORKED FOR ME, SO GO INTO WIRELESS SETTINGS AND TAKE OFF THE GSM ONLY SETTING

4g down or buggered phone?

Im in the DC area and my phone wont connect to 4g for life of me (im in a strong 4g area). tried toggling. tried forcing LTE only(either 1x shows up or nothing at all). tried turning off data for 10 minutes. tried removing battery. tried full wipe (wiped three times cache, tried clearing davlik cache and battery stats...three times) reinstalling 1.7. I can still connect to 3g and 1x. Just no 4g
i was initially on bamf's 2.0b5 and noticed i couldnt get 4g. so i restored back to 1.7 and still no 4g. and no i didnt forget to flash the appropriate radios. i called verizon to see if there were issues with the network in the area and they came up with nothing. is my radio broken or am i missing something here?

Try starting the phone up once without the sim card in and then reinstall the sim card and see if it works.

just tried that. no dice. any other suggestions?

Maybe take it in to vzw and have them test the sim. It could be fried.
Sent from my ADR6400L using XDA App

whoa. i didnt know that could happen.

same thing with mine I am in Manasasso area and i get 4g off and on but cant get on the market or google, then i back to 1x so is it a phone issue or a system issue.

Well with me its not even on and off. I get nothing at all.
Sent from my ADR6400L using XDA App

I'm sure this is a stupid question but it must be asked. Do you have the back of the phone off?

no such thing as a dumb question. just dumb people. hahaha im kidding. just trying to make light of the situation a little at least. i had a teacher that would always joke around like that so i had to say it.
but i digress, no the battery cover is not off. like i said, 3g and 1x works. just no 4g. can it be possible that just the 4g radio could be broken or if that were the case, i wouldnt have any data network at all?......
and as i was typing this message, my 4g connection had just connected. i think it has to do with the area where i live because I am now in my work building and it seems to be working fine now...i guess verizon lied to me... thanks for the suggestions. will post if things change.

Well, according to Verizon and their coverage map I'm supposed to get 4G at my house but I don't. Granted, I am on the edge. Now, here at work is a different story...solid 4G and it never looks for 3G.

Yeah, I am supposed to have 4g at where I live too. And I would get a strong signal too, which was why I was totally stumped when i couldnt get a 4g connection all of a sudden and verizon told me there were no problems with the network in the area.

this is happening to me as well. Phone keeps jumping between 1X and 3G all the time. I rarely get 4G anymore
I'm on Perfect Storm1.5 running the MR2.5 Radio chingy leaked
I have tried 4 different radios as well as ROMs over this past week, no change on either

been 4 hours and phone hasnt dropped 4g since. even flashed back to bamf 2.0b6. I would get no signal on reboot, but toggling works like usual again. i guess where I live is having problems right now. will post when i get back.

working now. im guessing its the network. running 2.0b6 with mr2.5

This was happening to me as well. I would sometime get "4G", but it's fake 4G, as I would not be able to receive any downstream data, and connectivity would soon cut out. I've gone from GingerRemix 2.1 back -> 1.7 -> 1.63 -> stock -> stock unrooted, and could not get 4G back.
I decided to throw in the towel and go to Verizon (with GingerRemix 2.1 loaded), to compare. They definitely had 4G in store while I was carrying 3G around. I told the "device specialist", and without much questions, he popped in a new sim card for me. I had 4G then until I was about 4 steps out the door, and it would fall back to 3G. The dude and I spent the next hour swapping out another card, placing my sim card into a returned TBolt, but no luck. Finally, he did a factory reset on my phone. With no further luck, he resorted to ordering me a new one.
Still unsure what the issue is since he did give me a new SIM, and that SIM didn't work on another TBolt as well. We'll see whether the new one that comes in the mail tomorrow will fix the issue. I've since then reverted back to stock, since I need to mail my "broken" phone back to VZ, still no 4G.

[Q] G2X 4G Problems

I've had this phone since release and have loved it. I have only one issue with it. I'll be trying to use my internet on the phone and it will show the upload arrow but the download will never do anything. I have full signal so this is not the problem. This happends a lot and in the middle of browsing it will do it... It will load a page and I'll click a link and it wont load and then it will work again after awhile. Does anyone else have this problem? Does anyone know a fix or the reason its doing this. Also I have full 4G coverage where I am.

It happens to me a lot too! Its very inconvenient and I know its not the area where I reside because I also have a g2 on my spare line and the g2s data works perfectly fine when the g2xs is stalling. :/

Did you get yours at release? If so it may just be the first batch or something...

Could be lots of things. Have you activated and are using the SIM that came with the phone. Supposedly the G2x uses a new SIM format.
What OS are you running? Are you on WiFi? 2G, 3G, 4G? Where does this occur?
I surf my with my phone a lot and I don't get that intermittent data problem you are describing. I am running the latest CM7 (#70) and in a 3G area with average signal quality.

I'm using the SIM that came with the phone and this is only on 4G I reverted back to stock ROM unrooted and still has the problem

I've never rooted my phone. I've actually swapped the sim twice already thinking it was the problem. Hard reset has been done. I've pretty much tried every trick in the book and the problem still persists. Its my 2nd replacement(1st one had the same issue)

P.s I got the first one at release then had it exchanged(buyers remorse period) for a new one towards the end of may so I doubt the 2nd one was from the first batch.

Like Player said, could be alot of things. For a sim, the G2x does not require a brand new sim, but it does require a newer sim. If your sim is older than 18 months, put in the one that came with the phone. Last years TMOBILE sim will work with the G2x.
Also, data plan. Didn't happen to me, but did happen to my son, the plan was not enabled for 4g Android. He got signal, rarely 4g...but did get 2g.3g. Walked back in the store..asked what was up...they checked...1 mouse click and finished. Funny thing was, he bought the phone from them, earlier in the day. You would have thought they would have covered that.

Your sons phone was showing 3g? Hmm... I thought on tmo 4g was a fast version of 3g and that the g2x only showed 2g or 4g. I am probably misunderstanding something.

So I went to T-Mobile just now and they gave me a new SIM and it fixed all the problems so if anyone else is having trouble try getting a new SIM first....its free

[Q] Only 4G Network Working

Well I have this SGS4G and I updated it to kd6 and it messed up the network. I almost never got a signal (it would show the circle with a line through it). I flashed it back to KD1 rooted and now it works but it only gets 4G network. Whenever I get out of range of a 4g tower and the phone switches to GSM it gets no network. Is their anyway to fix the radio firmware on this?

Please use the Q&A Forum for questions Thanks

Go to the market and download an app called GPS Aids. Go through the initial set up with it, then under the Tools menu at the top (not the actual menu name, but it's similar), then scroll down the screen until you see an option called Hard Reset. Give that a shot. Bear in mind that you will lose any data you have on the phone when you do it.

Kd6? Never heard of it... Have you tried flashing a different modem?

KD6 would be the gingerbread update. Phone was fixed with a new sims card even though we got a new sims card when it was bought, turns out it was one of the older defective ones

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?

I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.

iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only

Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw

I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

In the original post, I stated that was one of the things I've done.

have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...

I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.

I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps

Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it

Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:

Backup 4g Partition
REMOVED - was a bad idea.

I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
