Hi,
When data is downloading on the phone on 4G, then when a quit an 4G area, the phone keep trying downloading in 4G, not switching back in 3G.
Causing no network i can't be reachable, only way is rebooting my phone.
Did somebody already seen this beahavior?

I did the fix and i am on stock updated all the way from one of the threads in the dev section and before 4G worked with the old radio but cut out all the time So i decided to do this fix and now the 4G connects for about a minute and it disconnects and i am in an area with excellent 4G coverage. So if anyone knows of a 4G connection problem in the Kansas City area please tell me or if it is just my phone tell me how i can fix this problem.
Edit: It appears that 3G cuts in to do data instead of 4G because as soon as it cuts out 3G uses data.
Edit 2: Now if I go in to Setting>Wireless & Networks>4G Settings It says fair - Poor connection, Assuming because i am inside, but i am not connected.
Edit 3: After disabling mobile data in the network settings it now holds the 4G connection well but now i have to wonder why 3G would over take 4G while it is on.
I been having 4g problems since the recent ota update. I hardly get 4g and it's considerably slower.. I'm running full stock with no root. What fix is available?

anyone experiencing data drops particularly when the phone is in weak 4G coverage? It acts like it cant switch between 4G and 3G. sometimes it might take 5 min or more before it will reconnect to data. the phone works fine when it is in a strong signal area. So far I have just experienced this behavior in low signal coverage.
Yesss! Experienced that yesterday. But came back on in 5 min. Usually fixed when u go to settings and switch from the lte to GSM and back to lte but haven't had trouble with it today

Yours is the first case I've seen where data drops altogether, most have just been going back to 3G too often.

I am having the no data issue as well! I leave my house (on wifi and supposedly 3G or 4G) and I want to start listening to music immediately in my car but I have no data connection once wifi is off. It can take over a minute or more to get a data connection! I was wondering if this had to do with LTE protocol negotiation, as this is my first 4G phone. However it seems way too slow and its very aggravating. When it does get data back, it is usually 4G not 3G. Toggling data mode on and off doesn't fix it. I have not yet tried toggling between CDMA and GSM.

does it only happen when you're leaving wifi and going to cell data?
My experience with data connection was spotty for the first couple days. Going from WiFi into 4G then 3G on the way to work required a reboot to pick up the 3G after I arrived.
I think I may have found my issue.
Settings -> More... -> Mobile Networks -> Network Mode
Was originally set to "Global". I've found that "LTE/CDMA" works better for me.
hope this helps some.
I recently upgraded to Baja ROM from rooted JB stock and ever since have had problems switching to 3G from 4G. If I turn my phone on in a 3G area, 3G data works. However, if I travel to a 4G area and the phone connects to 4G, when I return to a 3G area, 3G data no longer works. The notification bar has a grey out 3G (wifi is off). Voice still works. I cannot get data again unless I either go back to a 4G area or reboot my phone. Turning on and off airplane mode doesn't help. Does anyone else have this problem? I have tried various modems, including NC4, NC2 and MJE. They don't seem to make any difference. Anybody have any suggestions? Thanks for you help in advance.
P.S. I live in Appalachian mountains where I am constantly roaming on Appalachian Wireless. They did partner up with Verizon to get 4G LTE so I suspect when I am on 4G, I am on Verizon network. I don't know if roaming makes any difference.
Hi all
I've been having issues with my 4g connection whilst on roaming since the last update. Everytime the phone tries to connect to 4g the connection completely drops out and then reconnects to 3g. Basically I can only get 3g whilst overseas and as the phone keeps trying to connect to 4g, it constantly drops out. This doesn't happen whilst back in the home country at all, only whilst roaming. I've tried a factory reset but the problem persists. Very confused and would appreciate any tips or help? Thanks all!
It's all too frequently dropping 4G or LTE connection when on the move. It's showing a connection, good strength too, but no data connection working. Often needing an airplane mode toggle or reboot to get online again.
5G is disabled as I'm nowhere near a 5G area.
Anyone got any ideas? Different firmware or something?
I'm starting to regret moving away from the SD note 10 plus I had. That phone was rock solid.

I read that some people have issues with connection with some ISP providers. Try putting it on 3G and see if it works fine then. If it does then ISP has either sn issue with 4G network or phone needs a firmware fix to solve 4G connection issue if this isn't a hardware problem thought. Since for me it works fine here and my 4G shows all time and I even have 4G+ as status without an issue.
try disabling WiFi calling that helped in my case
Tried all that. Went into a town and it didn't again.. Had to force it onto 4g to get a connection.

Haven't had any issues myself, on giffgaff. Tried O2 briefly, it seemed okay too.

Give this app a try, might help fixing it to one band

Yes u have that thanks. It seems to be band switching that's the problem. Or is it possible my carrier has live but unused bands that the phone is locking into? So when I travel I find myself with a dead data connection?
