I've got my unlocked Vibrant running on AT&T, but I can't seem to get it to switch between Edge and 3G. I can go into the settings and set it to stay in WCDMA mode, but then when I'm in an area of bad reception I end up missing calls (All through VOIP).
When its setup for Edge/WCDMA it will stay in 3G at first, but when 3G gets too low and it goes to Edge it won't go back to 3G at all.
I've tried switching modem versions but I'm guessing its unrelated to that.. well, actually all Vibrant modems are going to be setup for Tmobile anyway, maybe a Captivate modem is the solution, I'll try that and get back.
Does anyone have any ideas of how I can get it to switch properly?
If this modem install doesn't work I'm all out of things to try.
Thanks.
As far as I know (and I could be wrong), you can't flash a Captivate modem to the Vibrant, it just makes the radio useless.
You will have to use Vibrant modems, since they are designed for the hardware IN the Vibrant.
Hi guys. Me and my wife both have gs2 and we both are on tata docomo 3G network. The speeds are good and this phone is awesome, specially for someone coming from a blackberry like me. However there is a peculiar problem both of us are facing. The data xonnection sometimes hangs on 3G and does not move to h or h+, and in 3g therd is no data transfer. The data transfer happens only on h+. That means for all practical purposes there is no data transfer. Sometimes it alsi so happens that the phone is showing the h+ icon but again there is no data transfer and i cannot access any internet related app. In these cases when the data hangs the only option is to activate the flight mode and then again reconnect. Then the data works fine. Off late this has started happening a lot. I have tried a couple of things like deactivating h and h+ and working only on 3g but to no avail. Can anyone help with this. I have not been able to test on other networks so i cannot be sure whether this is a device related problem or due to the network. Any help would be highly appreciated.
Regards

I am also facing this exact issue. I am on Airtel (India) network. For me, it seems to happen when I am at some particular locations, and works smooth at some other locations.
I just deactivate data network mode and re-activate it (long press power) instead of flight mode, takes only 10-15 seconds.
Don't know if rooting and using custom roms will fix this issue, because I strongly believe it to be network-related. I used to have similar problems with HTC Desire with various sense/AOSP custom roms.
He y buddy. But if ur on airtel and i am on tata docomo and we both r having the same problem, maybe it is not a network problem and is rwlayed ro some handset setting. Did u try the *#302179# trick. Did it work for u. Same problem in othe networks and for some of them this trick worked.

And by the way thanks for the data connection mode trick ( long press). Atleast it is a better way to make it work.

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Happening to me as well.
I always thought it was vodafone's poor network as my phone never downloads data when 3G is showing, it will only show upload arrow, then when it change's to H I get both uplaod and download arrows and starts working fine.
One thing I did notice though is when in Gran Canaria 3G was showing and working and data speed were ridiculously fast compared to here in the U.K
Surely this must be related to kernel used???
I have the same issue on my I9100 KI3, KF4, KG2 stock rom with either KG2, KF4, KI3 or KI4 modem. This is a combination of tower and our phone modem or kernel issue. I am having this issue with AT&T USA on KI3 and KI4 quite often in Champaign, IL. But when I went back to my country in Asia(Taiwan) 3 months ago, KI3 rom and modem have no 3G issue at all. I was on 3G 24/7 for 3 months without any issue there. However, I had the same 3G issue in Taiwan when I was on KF4 modem with KF4 rom when I first bought the phone. This is really a funny issue. I tried all the tricks and switching so many rom and modem, but 3g hang still happens to me with AT&T network. Now I am trying to lock the WCDMA band to 850 only, see whether it helps.
having the same issue here, but im quite sure its network related, inside my office the 3g dissapears at all and the same happends to a friend of mine who owns a SGS2 as well. whenever my outside the internet works as intended
also flashed trizillions of roms and modems before i gave up and blamed it on network rofl
Hi all,
I'm having a data connectivity issue on my phone when moving from 2G to 3G. If I'm connected to 2G, then move into an area of 3G coverage the phone will successfully migrate to the 3G network, however the data connection will often not start up for between 30 minutes and severanl hours. Flipping airplane mode will *sometimes* fix it, but more frequently, even rebooting the phone won't work. However, if I lock the phone to 3G from the settings, I do not encounter this issue at all. It only happens on my home provider (Jersey Telecom - they're small). In the UK, on Three, it didn't happen.
So, given that the problem can persist over reboots, and doesn't happen in the UK, it makes me think it's more likely a network issue, so I called them up. The network engineer managed to reproduce the issue on his colleagues Samsung Galaxy Note, but they are adamant that it's a phone issue and not a network issue, and is a matter of Samsung not sticking to the specs. The phone isn't currently rooted, but I can root it if it will help me debug the problem. From the sounds of it, it may be problem consistent to all Samsung radio phones on our network.. and I really don't want to switch to another phone.
They say that from their logs, the phone is not always trying to create (or presumably, migrate?) a PDP when moving to a 3G network. It's hard to say whether it's a problem with the phone or their logs.. has anyone else experienced a similar issue? Does anyone know how to access logs about the phone trying to create a PDP etc. so that I have something to compare with theirs?
Thanks
check out the modems thread and try a better modem

Hi,
I have been experiencing a few issues with the 4G LTE on my LG V10 H901 (T-Mobile). What happens is this.
In Network mode I selected GSM / WCDMA / LTE Auto. This initially worked fine and could get a data connection. 2 days after, I noticed I couldn't get a data connection anymore, the 4G LTE icon at the top was displaying with a down arrow lit. So I went in the Network mode and checked my APN everything was ok. Decided to switch from GSM / WCDMA Auto where I got a 4G connection (icon 4G displayed at the top) and I finally got a data connection.. Changed it back to GSM / WCDMA / LTE Auto, and there I was back on LTE... I had to reboot my phone and that is when I noticed the same thing happened again!!! No LTE connection and had to first select GSM / WCDMA Auto to get 4G.. If I reboot with GSM / WCDMA Auto I get a data connection fine.. The problem only occurs when I have the Network mode on GSM / WCDMA / LTE Auto. Anyone else having this issue? Is there a fix?
Thanks
I would say it's a hardware problem with the phone I've had mine for a month i never touched network settings and the phone gets a better data connection then any phone I've ever had LTE pretty much all the time where other phones wouldn't maybe a factory reset would fix it worth a shot
The first V10 i got from T-Mobile had somewhat of a similar problem but with WiFi, it would connect but speed was horrible. And LTE isnt that great in my area either. I read around the forums and notice that many have done factory resets and that fixes everything. I did that and lowe and behold, it did. WiFi was fast again and LTE speed improved but still sucks....its my area, not the phones fault. For some reason, a reset helps.
However, I was still just 4 days in since I got my phone so I just went back and had them replace it. I just told them that the WiFi doesnt hold....they didnt really ask me tons of questions. I replaced it only because I am paying for the phone and me having to do a "fix" to make it work doesnt sound right...so I want a new good phone lol. The new phone worked fast from the get go...no reset needed.
Just got the V10 was having those wifi issues initially so brought phne back n exchanged for another 1 and this 1 workes fine but now Im having dropped call s inside my house ,verizon said no antenna issues i can bring phne back n replace for something else or another v10 but that is time consuming ,please anyone having drop d call s....I live Long Island NY so verizon overage is better then most carriers...INaNYmin...
I began having the exact same issue on Jan 16. Had the phone since Dec 25th, worked perfect. Then, all of a sudden, it began to lose LTE connectivity. At first I thought it was a down tower, but the problems persisted an eventually got much worse wherever I went. On a full charge the phone will behave normally for a while, but eventually it starts losing data connectivity altogether, cycling between 4G LTE, 4G, 3G, 2G, trying to connect. during this process the battery drains a lot, it never really connects, and sometimes calls and text messaging fail. Tried every network setting, soft reboot, hard reboot, safe mode, clear cache, factory reset....problem persists. T-mobile concludes it must be defective. We shall see. Awaiting a replacement.
Having the same issue. Looks like it's a common problem. Any fix for this yet?
I have a similar issue.
it always seems to find the LTE signal, however I have no data and the battery drains very quickly.
If I have it on GSM/WCDMA/LTE, it seems to have connection issues. However, the data will connect on GSM/WCDMA. Once I have data, then if I select GSM/WCDMA/LTE, and it will connect to LTE
It is a Tmobile version. I am using it on Bell (Canada)... however it works fine with Wind & Tmobile, with no issues.
I am hoping that this will be fixed with the Marshmallow upgrade.

Wind works on hspa not LTE. That's why it works. I've noticed that it works fine on hspa(4g) but when I put it on LTE(4gLTE) it works for a while then stops.

For me, Wind works fine on GSM/WCDMA or GSM/WCDMA/LTE
With Bell, it will not connect on GSM/WCDMA/LTE.
However, with Bell, if I put it on GSM/WCDMA, it will connect. Then if I change it to GSM/WCDMA/LTE, it will connect to Bell's LTE.
Occasionally, it will lose its data connection... and then if I toggle between GSM/WCDMA & back to GSM/WCDMA/LTE, it reconnects. This seems to happen once every 2-3 days
I don't know why it does this. It was actually very frustrating until I figured that out. I almost dropped Bell because I was not able to connect on LTE for the longest time!!
I just keep my Wind plan for the US roaming (on Tmobile LTE down there)

Yup exact same issue with me and that's how I resolve it as well I'm with koodo and I lose LTE. I was going to warranty this phone but I think it's a common issue.
I just want to quickly point out that I am seeing the exact same issue on Virgin Mobile (Bell). I also noticed that the performance of the phone decreases drastically when it is connected through mobile data instead of WiFi. Anyone else sees this and knows how to fix it?
Lg v10 t mobile no connection
I'm having a similar issue I get a 4G LTE signal but if I make a call once I end it I loose all signal including the bars it wont let me text or call it says network not available and it will do that till I travel a few miles. I'm not in a dead zone because it does it in the heart of the city and on the buisest streets in Tampa Florida then it will come back and sometimes I won't get a signal for a entire day out shoe have any solutions?

Hey,
I'm using this phone in Canada too, on Telus. Ever since the OTA update 2 days ago I've been having data connection errors over the network. Did you find a fix?

I'm seeing this too, but it just started after my OTA update. So frustrating bc I love the phone.
I had a similar problem. With The latest software (,,v20c,,) With the LGUP Software I software put it back (,,v20a,,) . And it seems the problem disappeared. Last part of the modem software is not good. Even test elements. Sorry for my bad english for knowledge. LGUP software very simply . ( i have V10 960A Unlocked (Eu version) android 6.0 and T-mobile LTE )

I just bought a LG G5 RS988 (Unlocked Model) recently and at first I had really bad connections indoor I said to myself this is probably normal.
Then I just saw that the phone seems to be only in 3G in the corner but apparently it's suppose to be able to get 4G.
I googled it and apparently it happened since the nougat update, many users lost the ability to use the 4G connection.
I'm I the only one with this issues ?
The phone boots, it stays on LTE, on the main screen then once you logon it switches to 3G WCDMA and stays there.
I have 3 options in the data menu tried all the ticks (Global) and it picks up the LTE 3G, the LTE/GSM somehow disable the whole data mode and the other one too, and the only way to get the phone to have a very good connection is on GSM only by accessing the secret DEV debug option :
*#546368#*988#
Select Field Test, Modem Settings, and RAT Selection, then selecting GSM Only.
Then my data bar goes full or 4/5 inside my apartment near the window.
GSM / WCDMA / LTE Auto :
LTE only : Makes it a X Disabled
LTE / WCDMA : Goes on 3G 2/5 bars
LTE / GSM : Goes on 3G 2/5 bars
GSM / WCDMA : Goes on 3G 2/5 bars
WCDMA : Goes on 3G 2/5 bars
GSM Only : Goes on normal G 4/5 bars
It's like the LTE doesn't work at all...
My experience
I've been researching the issue myself. I have found that it's either your carrier's network doesn't "whitelist" your IMEI number, so it won't connect to LTE, or your phone doesn't fully support all of the bands that are needed to connect. I have the RS988 and mine needs to have airplane mode toggled on and off or the carrier settings toggled to global and back in order for it to go to LTE. Otherwise if I try to use the LTE only setting, I cannot make or receive calls.
In other forums, they mention downgrading the OS to marshmallow to get LTE working again. I tried this... It was painful to perform and after a bootloop I finally got the phone to stock marshmallow. However, once I finally got it working and I made a call, it went right back down to H or H+ and stayed there.
My impression of the issue is that someone could make an app to toggle back and forth from the original carrier setting (LTE/GSM/UMTS) to a second setting (GLOBAL) and back to the original network setting (LTE/GSM/UMTS) after a call is made... This would be a simple way to fix the issue and get back on LTE even though it isn't perfect. This is probably your best bet to get on LTE because even custom ROM's don't seem to fix the issue for me.
It's a very bizarre issue. If anyone else has a better answer or more knowledge on the issue, please let me know.
If anyone knows why this phone seems to specifically have these issues, also please let me know.
