So, I've done quite some looking around in this forum and others but have not been able to to find an answer...
Here's the issue: when leaving an area with wifi connection, my galaxy s refuses to connect via 3G. Sometimes the "H"/"3G" is shown but no data is being transfered, sometimes the "H"/"3G" doesn't even show up. I've tried switching to plane mode and back, but that only helps sometimes. Switching to 2G and back doesn't help either, neither does re-selecting my provider from the provider list in the wireless settings or turning wifi on and off.
I'm on JF3 still. And here's the question: Is this an Eclair bug or firmware related? And is there a workaround, besides switching to plane mode and back every time I leave the house?
Your help is appreciated!

I have similar issue too. I hated it.
It appears to be an Android problem.
http://code.google.com/p/android/issues/detail?id=2207
I have this problem too, running an optus one.
I think sometimes.. going into the APn seetings, clicking on the field, dont change anything and press okay.. so it refreshes the APN settings and it works?
Or I rescan for networks. and choose my optus provider again.
Such a fluke.. that first few days i got this phone didnt have this problem.. and now it does... hope it gets fixed soon.
Okay, thanks. will try my luck with the android developers...
I checked out the link to google code and there seems to be a solution: restoring the default apn settings (hit the menu button when in the apn list). Seems to work, at least for now, my 3G connection came on when I left wifi after being on wifi for a few hours.
Greetings All,
Got my Xoom back from its 4G upgrade last week and I have been noticing some issues with connecting over the 3G/4G network now. I use pocketcloud to connect to computers over RDP and when connected over WiFi networks, it works fine (computers connected to networks other than one I am connected to WiFi on), but when using the 3G or 4G connection on the Xoom, there is a network connection error. I tried it out on my incredible and it works just fine. Also, sometimes I get an error "cannot update" from the engadget app.
Also, the new market would not install some of my apps, like ThinkFree Office for example, I worked around it by using the web interface of Android Market on my computer and it worked fine.
I sent in the Xoom completely reverted back to stock 3.1, I recieved it with 3.2.2 stock. I cleared memory after I got it back and did a factory data reset. Not rooted, and no other modifications have been made.
I'm at a loss as to why some connections are causing the network to flake out.
Regards.
I read on here that some of the app installation issues were due to the possible change in pixel density that took place with the upgrade but that is something you can change back if you root.
I'm noticing the same exact issue and have no idea what is causing it - let's see if together we can figure it out. It's extremely flaky so far.
I got my upgraded Xoom back today and noticed the exact same issue. It wouldn't activate on the setup screen and prompted me to reboot. After reboot, it connected to 4g just fine and showed the 4g icon below.
I then went into the market to install my apps. It installed Thumbkeyboard just fine but when I went to install others, it stopped at 8.03k on the download. Did this for every app i tried.
I turned on wifi, connected to my AP and the downloads worked just fine. Even tried a couple reboots before doing this and it didnt work.
My 4g signal is about 75% so it's strong.
Very strange...
Power off
Remove SIM.
Put SIM back in
Power on
Done. Worked for me.
I take it back, still having all kind of issues.
just got mine back this morning, and it wont connect to anything! no 3g, no 4g, no wifi... nothing. WTF!?!?! restarted, pulled sim, etc...
going to do restore next and see what that does.
Same connection problems
Got my LTE upgrade back.
When I am at work I cannot update Touchdown from inside the firewall (not sure why) so I flip back to Verizon to refresh by shutting down the wifi. When I do, I noticed that the xoom would drop the connection (three bars) and then not reconnect. When I try to turn on the wifi it stays grayed out and neither system will connect until I reboot.
Went around with VZW tech support, they reported that the unit was registering on their network but not connecting. Sent back to Moto for further testing, got the unit back (they reported it was a software fix, no other data) but the unit continues to have the problem.
Stock 3.2.2 xoom with LTE
Any suggestions appreciated....
Has anyone been able to resolve this issue?
Hello, I am still having all kinds of connection issues after I received my device from Motorola. After a reboot the xoom will connect to the Verizon network but If it stays idle for some time, I lose the connection and it will not connect until I reboot the device.
sent it for replacement
I had the same problem. I had to send it back once for 'repair' (no improvement) before Motorola replaced the unit due to an undefined hardware problem. Keep calling or go to a store.
I had something similar when I got my Xoom back. Apparently the geniuses at Verizon never added the SIM to my account. Took multiple calls/emails to get it corrected. Once someone realized it was missing it was corrected in about 10 minutes.

In your case did you have sporadic connection or, without the SIM number, were you completely unable to connect?
BTW, I missed this thread when it was fresh (as I was traveling) but I've had the exact same issues since the LTE upgrade. When it happens, the only way to reconnect is to reboot.
I used to be able to get it to reconnect by switching airplane mode on and off. Sometimes I had to reboot. Friday, even that did not help. I was furious. The next day, the update pushed out to me via wifi. I guess the servers recognized me as a customer again even though I already had a 2 year contract. Some people got the dataplan because they don't use wifi. I love the shortsightedness of the people who come up with this... not.
At least I haven't gotten disconnected since the patch was installed.

I had to unroot my device for 4G to start working normal.
I have bought my Lg G2 last saturday. I'm still researching the phone and so far it's great except one thing. Problem is when the phone is removed from charging it refuses to establish a data connection. This happened to me twice and every time in the morning after the charging.
Solution is restarting the phone. If not, it just won't connect . When i go to the settings it is turn on, but there are no arrows at the top of the screen and it doesn't work. Otherwise , after the restart it works normally all day. I keep turning it on and of and it works fine.
I think it is a software problem, since I have a network signal, but I'm not sure.
Is anyone having a similar problem?
Thanks

No, I have read about that today , but as a solution for a samsung g3 . I will try in the morning, because after the restart it works perfectly all day . Do you think it is a software problem?
Are you using different charger and cable or the originals that came with the phone?

I'm using original usb cable and charger, but with extender , because of the electricity. Phone is from England, and I'm from Serbia .
After the last night charging I had the same problem, but this time I used toggle between Airplane and Data . After that everything worked fine.

Hi, i noticed this too since a couple of days... Trying To figure out what the issue is ( in possession for 2 Weeks)
I can re-establish data connection without reboot by clicking in select automatically in network operators in data /mobile networks settings. So it will reregister on the network.
Guess we need to notify lg about this issue/bug for a fix.
my sprint g2, will drop data connection occasionally when switching from wifi to 3g or from lte to 3g. so i would say there is some kind of real issue here
Same problem after rooting
I'm having the same issue, the data connection drops, mostly after going into stand-by. The problem started to occur a few days later after rooting the LG G2. I have tried the temporary solutions above with succes, but there is no final solution to it. I wonder if the device intentionally starts to brick itself after rooting, I heard the LG G2 has a lot of root checkers (says the noob).
Anyone contacted LG yet? Or tried flashing their device?
I'm having a similar issue with my G2.
After switching off wifi, data won't start.
I have to click search network then it would go on.
Would it be something to do with the modem?
When i had my Samsung gs2, I had problems with random dropouts, then I found a way to flash new modem software and all worked fine with better reception and no dropouts.
I sometimes loose network connection completely (no service) when switching from 3g to 2g or vice versa, no issue with 4g what I've seen.
Though I have this BBS, looks very alarming I must say, does anyone have similar to this:https://db.tt/aKsiw0Xe
https://db.tt/9iMHIZvm
issue fixed
hi after a recent software update (mine was D80210c-HKG-XX, build number JDQ39B,...) the data connection issue is solved for me (also made a LG support case).
But my NFC funtcion stopped working now...
Same here. Ive got this issue after rooting the G2. It cannot connect to mobile data after Im away from wifi connection. Switch airplain mode on and off helps but its annoying even if u have more email account. Another problem after rooting was freezing and restarting phone after mouse connection. But next day was everything fine and its untill today. Have anyone similar issues with custom roms?

I am rooted running Digital Dream on a Verizon VS980 with 12B radio installed. I loose data or go down to 1x all the time. I have to toggle airplane mode or reboot to re-establish 4G connection. Is there something else I can do. I love the phone but the data thing is annoying. Is the antenna really that bad in these phones?

I think and Im almost 100% sure that this must be only software problem, because when the data is runnig, it runs fast and stable. No additional inconvenience.I hope next upgrade (update) will fixt it. However Im really surprising that u have same problem on custom ROM. Im using only airplain mode to switch the data on. I needent to restart device, but it is really really annoying.
Hi everyone, as I wrote before got data connection issue while getting away from wifi. The data cannot start automatic. I found out that it happens only if GSM/ WCDMA /LTE automatic connection is selected in the settings. When I adjust GSM/ WCDMA automatic connection - everything is ok. I was trying automatic switching and runs perfect. So if u dont use LTE, better say if the WCMDA is enought for u, it can be less annoying solution as manualy turn on/ off airplain mode. I hope next update fix this issue at all. Have nice day.

It seems better (still not perfect) I wiped everything including formatting the system partition and re-installed... But thanks for the replay!
Also, I don't have to reboot ... toggleing airplane mode takes care of it, i was just saying reboot is another alternative.

This is definitely a software problem, but I have no idea how to fix it... when I first rooted everything was fine (I was on Malladus). Then I went to CM-based ROM and it was still working well.... then I updated my PRL (*228) and things started going south and I haven't been able to get it back working since.
I'm thinking of going back to Stock and starting over from scratch to see if I can fix the problem.... if anyone has an update on this issue I would greatly appreciate some advice!
potential fix for this issue?
Hi everyone. I had this phone for about 3 months. and the data connection thing has been annoying for me.. So the problem to start off with is at first I dont seem to get LTE at all during the first 2 days. I found online that the 3845#*802# or *#*#4636#*#* got me into adding LTE back into the system but problem is when I reboot. it goes back to WCDMA only or GSM WCDMA. and I lose LTE. But atleast I have LTE when I didnt reboot it. Then I found another problem which is losing data after I used LTE for a while. It won't reconnect until I reboot the phone or SOMETIMES it will return if I go into airplane mode and back. After some long research. I found this to be working for me.
So this is my story of how I got it to work for me
To start off with. This is what I am using
LG G2 D802
Android version 4.4.2
Baseband Version M8974A-AAAANAZM-1.0.190082
Kernel Version 3.4.0
Build KOT49I.D80220b
Software D80220b
My provider is Metropcs so if anyone has other issues with other providers. I don't know if this will help you.
First thing this phone needs is it has to be rooted - that part you do your own research and wont be hard since you are on XDA!!!
Then to get LTE working, you will need to type in 3845#*802# on your phone to get into the hidden menu
LTE-only ---> Modem Settings ---> RAT selection and select GSM / WCDMA / LTE Auto (will display SUCCESS) tap OK
This will give you LTE from the phone but it will not give you this option in your Mobile Networks / Network mode section (Preferred network mode) Atleast it didn't display it for me.
For my phone I had to edit the build.prop file for it to show it in the preferred network mode list.
In the build.prop file. You will have to look for this line and change the 9 to a 11. I've also saw some post about it being not a 9 and have to change to 12 for some networks. ALSO MAKE SURE YOU DO NOT CHANGE IT TO A NUMBER 0. It will crash the phone.
From
ro.telephony.default_network=9
To
ro.telephony.default_network=11
After this I got me LTE connection but issue with the lost of settings after reboot started. So next part helps with the reconnection after reboot. I got this from a post in XDA So give credit to the person that posted this. Sorry if I dont have it handy as I wrote this
- Root
- Install and activate Xposed fw
- Install and activate Intelli3G module
- In build.prop change ro.telephony.default_network=9 from 9 to 11
- Create a Tasker profile of type Event -> System -> Device Boot
- Associate the profile to a new Task of type Misc -> Send Intent
- Configure the task by setting in the "Action" field the value "action.intelli3g.CHANGE_NETWORK_TYPE" and in the first "Extra" field set the value "extra.intelli3g.NETWORK_TYPE:10"
Doing this got my reconnection after reboot fixed. and LAST is the problem of randomly losing data connect until I reboot the phone. and after a long test.. This is my result. The phone lost connection due to trying to connect to LTE with non existing band. I don't know too much about those but from my testing. This is how I made my phone worked and it has been working for the last 2 weeks without any issue.
Go back into the hidden menu with 3845#*802#
LTE-only --> Modem Settings --> LTE Band Selection
Here you will see a Band with a number.
MetroPCS supports band 2, 4, 5 and 12
Since this phone doesnt have 12. You only select 2, 4 and 5 then just push back until the hidden menu closes.
Other providers. I dont know what band that they use. but i am guessing if you only select the bands that company supports. You might not have that issue with losing data anymore.
Please press thanks if this works for you.
I'm finding that WiFi calling stops working randomly. A reboot gets it to work properly again. I have my advanced call settings on Global and Wifi Preferred as my option.
Anyone else having this issue with Oreo 8.1 and T-Mobile?

I've had this issue since I upgraded to 8.1. I've been planning on doing a factory reset to see if it fixes the problem, but I really don't want to go through the hassle of setting everything up again.
I have no cell signal at my desk at work, so I use the WiFi calling often. However, I have noticed something rather strange. If I try to make a call or send a text, it will sometimes say something like "No WiFi network available". There have been a few times after it has done this that I have received a call on WiFi, and then it will work fine for a while. Otherwise, a restart fixes it.

Another thing that I noticed is that when on Wi-Fi calling, sometimes the phone will only ring once before a call goes to voicemail. Seems like there may be a delay in the call coming through. I generally have a good Wi-Fi connection, but like any Wi-Fi connection, it can come in and out occasionally.
I want to avoid a factory data reset as well.
I have the same problem Essential on Sprint
I am also experiencing this since the 8.1 upgrade, 8n T-mobile. Multiple networks that had WiFi calling pre-update are no longer functioning on either of our phones(wife and I both have them). I often work in a basement, so this is an important function for me.
SOLUTION AT BOTTOM
Seems like over the last day it doesn't want to stay connected to the Voice over Wi-Fi. If I toggle it it'll stay on for a few seconds and then the icon will disappear.
This is on both mine and my wife's OnePlus 8 Pro.
I've tried to restart device.
I've toggled airplane mode on/off
I've manually entered the APNs per T-Mobile's website even though the auto set ones by the phone were the same.
I went into *#*#4636#*#* and it shows I'm provisioned for Vo-WiFi.
I'm stumped. Is the network just being glitchy right now or is there something I'm missing on two different phones?
SOLUTION: Well in short OnePlus needs to send out a patch to fix this. How can you report a bug to them to fix?
Here's what I found out. Someone feel free to change your own router settings and see if the same thing happens:
My WiFi is set to WPA-PSK [TKIP] + WPA2-PSK [AES]. It doesn't work on that. If I set it to WPA2-PSK [AES] it works fine.
There are plenty of hotspots out there that are set up to one and some to the other. There's no reason it shouldn't work on either. Regardless, I changed the setting on my router and it's "fixed" but OnePlus needs to send out a patch or something.

Well I'm stumped it doesn't work at my house or my local supermarket but at my mother's house all day today maintained a Vo-WiFi so something to do with the routers... The investig continues
Yeah when I'm at work or at home I have no issues of VoWifi, mines works perfect on my 8 pro with TMobile prepaid

That's definitely interesting. My friend down the street got the OP8P the same day as me. He seems to see VoWifi more than I do. If I toggle airplane mode, I'll get VoWifi for about a minute before it eventually switches back to VoLTE. I also am having some stability issues where the wifi signal is there, but goes bad... and the cell signal disappears altogether. If I toggle airplane mode, it goes back to normal (see attachments).
(EDIT: Not sure if both screenshots are showing, as the XDA app seems to be acting weird)
Okay this is DEFINITELY a OnePlus software bug I sent them an email via their customer support.
If I connect the wireless bullet z, wifi calling works and maintains a signal. I disconnect from all bluetooth devices and within a minute bam wifi calling icon goes out.
Updated original post found the "solution" myself. In short, how do you report a bug to OnePlus?
