Question How to fix faulty mobile network on Exynos? - Samsung Galaxy S22

I have a Galaxy S22 Exynos and I have troubles with mobile network. Although the phone shows it has full 4G or even 4G+ connection, Internet doesn't work at all, and only up arrow lights up. Turning airplane mode on and back off again seems to temporarily fix it. I've tried countless methods in order to fix it, but nothing seems to work. How to fix it?

I has same issue.
Moscow, megafon...

I have the same problem, its hardware issue and samsung doesnt want to admit it. I sended mine to warranty repair and hopefully they will fix it.
I had contacted samsung support for help and they asked to reset network setting, then all phones settings and then full format but none of those fixed the issue. Then they started to ask for log files but it wasnt possible to take the log file they asked for because it needs OTP password which i cant get because its only for samsung repair center. After that they said i should bring phone to repair.

Any news about this problem?
I'm tried switch mobile network to 3g/2g only mode and this is help, but not 4g or 4g+.
It looks like the phone can't switch from 4g+ to 3g mode and stuck.

I looked which band is faulty using the *#0011# code, and restricted bands with the Samsung Band Selection app from the Play store

[Q] ATT signal troubles on H815 US

I purchased my phone (h815 US model) online from swappa and I love the feel and look of the phone, Love the camera, BUT my phone wants to stay on hspa all the time. Where i had 3 or 4 bars on my s5 active I get HSPA unless I go in to settings and sellect ATT:LTE from network operators which only last until my phone goes to sleep then im back on hspa. Anyone else experiencing this? Or anything i should try? Thanks in advance for any help!

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe
I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.
AT&T APN settings

After that, it's been using LTE where available.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......

Help 4g

Hello friend, i bought a new m9 and when i activate data mobile i have only 3g , i tryed factory reset, to setup my network,
I rooted my phone, installed custom room.. still no change.. anyone can know why ?
Well maybe you dont have great 4g signal in your area? Or change apn.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.
at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.
Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

That's a network issue, get a new sim and speak with your provider. Try the things I listed too

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything
Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.

4g/Lte no connection after flashing RR

Hello,
since I updated my OnePlus 3 to the newest Resurrection Remix I have problems with LTE/4g. If i activate Mobile Data, i only get EDGE with a low bandwidth. I called my Mobile Provider and they said, that in my area LTE is working perfect. I eject the SIM Card and placed it into another smartphone and after two sec. i get LTE/4g with a high bandwith. A factory reset, returning to Stock Rom, deleting the APNs didnt work either. Is there any soultion fo this issue?
Maybe I crashed my modem ? Is it possible to flash everything back to Stock ?
Thanks
type *#*#4636#*#* in your phone dialer, phone info, scroll down and set prefered network type to LTE only. you will be unable to call while in this mode so do not have it turned on. just test it if your 4g works

well then your phone is broken or your service provider is messing up. but you already called them and they said that it was all ok on their side. so that means there is certainly something wrong with your phone

Galaxy watch LTE - disabling eSIM on non supported market

Hey guys,
I found LTE unlocked variant for the price of BT (30€ more). ESIM is not supported here so I still cant use the full functionality but I'd buy it just for those 1.5gb memory if not anything else.
Does anyone know if its forcing you to "insert" esim because wouldn't like to have constant popups saying insert sim/no network., or can network connectivity be somehow disabled and normally used as BT/wifi edition until the operators support the LTE?
Thanks,
Maybe if you turn on Airplane mode, then switch on BT and WiFi manually.

Thanks - I actually didn't know that was possible on either Tizen or Android :good:
Maybe this info is useful....
TizenOS allows you to activate airplane mode, but from what I've seen you still need a SIM card in an LTE unit. There may or may not be a way around this yet; all the Telephony packages seemed pretty concerned about checking the SIM card constantly and throwing errors whenever it was missed. Lucky for us the Telephony is left at Partner level, so with an SDB shell you should be able to just type something like:
Code:
sdb shell uninstall org.tizen.telephony-syspopup*
and the nags should cease to be forever. Not sure if that's exactly the right command string to work, but I'll check when I get the chance to.
Hope this helps.
You can simply disable LTE connectivity in the setup Menu, like Wifi or NFC. Before i activated the eSIM on my watch i didn't get any pop up or message to activate the eSIM. So i would say it is no problem to use the watch without the eSIM. With disabled LTE it works exactly like the BT model.

So I bought a LTE watch and found the place to disable mobile networks.
In Settings, go to "Connections" -> "Mobile networks". Anyway, its off by default when I purchased the watch, and I can confirm that I've never had a single pop-up message asking me to activate.
I purchased the LTE version of the watch in the US directly from the Samsung website.

Hi, It is an esim, so techically it is already 'inserted' in your device. You don't have to set up a connection if you don't have to, just use the watch like the BT version. There won't be any popups or errors. Just switch off mobile data completely under settings, as it eats battery like nothing.

I am also interested if there is any difference in battery life between a Galaxy Watch Bluetooth anbd a Galaxy Watch LTE but with "Mobile Networks" off in the setting menu.
I'm basically wondering if there is any additional drain from the LTE services that run in the background even if the setting menu says LTE should be off. If so, I would like to know if I could turn off those background services to extend battery!
Mine was off by default, but I do not have service on my watch, so that may be why. As people have already said its a eSim(embeddedSim), so its not able to be removed, and wont hurt anything by being there.
