I have a Galaxy S9 since 1y and it worked fine. Recently I updated the software to the latest version, and I noticed my 4G doesn't work. The symbol shows, but only the arrow UP is constantly lit. The DOWN arrow is blank. I contacted my provider and they saw no problem. They have given me a new SIM-card, without any result. When I put this SIM-card in an old S6 device, the 4G connection works fine. So I think the problem is with my S9 device. Maybe it has nothing to do with the update, but I think this in not a coincidence.
Anyone has this problem too?
I have no 4G symbol either on my S9.
The settings is on 4G.
But if I turn of wifi the 4G or 4G+ symbol comes up.
So I think the S9 prioritaise using wifi and when wifi is not availible S9 goes over to 4G.
I have the exact same problem (4G arrow up, sim swapped, no solution). Also did an update recently. I contacted my provider (Proximus Belgium) and they said this is known issue at Samsung. I have changed the settings to only connect through 3G/2G and that works. Don't forget to reboot after you've changed the setting.
Here, in Belgium, the same problem. After the update: no 4G anymore. Changing the settings in 3G/2G works, but that isn't a solid solution. Hello, Samsung? A reaction please! We want 4G back!
I have the exact same problem since the update in december.
*4g not working
Did a network reset, which solved the problem teporarily, but the issue is back and not even a reset can fix it now.
Hello Samsung! This is a pretty serious issue. Fix please.
Hey guys, glad to learn I'm not alone, upset to find out there is no solution
Got my fresh sexy S10e in December 2019, I bought it in Mother Russia. Nothing even remotely close to the issue in question. As soon as I turned Wifi off - I get connection whatever my phone can receive, including 4G. All was great, even though the network that I use in Russia (called "YOTA") is known to have mediocre to poor coverage.
Came back to the UK and, as usual, wherever I go - the Internet connection is utter garbage (no matter the number of bars your cellular/wifi symbol displays).
I started experiencing the problem right after I came back to London. For me it works like this: after using WiFi, when I need to leave the location - I turn WiFi off and LTE does not pick up. In fact, nothing does. I simply get the network bars without any Internet symbol and, obviously, without any internet. I tried airplane mode, restarting (2-3 times in a row won't help), fiddling with settings. Only now I tried downgrading to 3G and it is working as good as 3G would.
I do blame the network (giffgaff) as I never experienced the problem with a Russian network, however I also need to note that that never happened when I was using my iPhone 7.
Gonna contact both Samsung and the network tomorrow.
