Last night I went into Service Mode on my SGH-T889 and as soon as Service Mode opened, my 4G icon disappeared and then kept cutting on and off. I didn't even change any of the settings in Service Mode, I just left it as it was and rebooted. Now, after multiple restarts, re-entering the APN settings, and a hard reset, I'm still having this problem.
Has anyone else had a similar issue? Were you able to correct it, and if so, how? I have been searching all day but can't find a fix. I can still make and receive calls and texts, just can't stay connected steadily to use my internet connection. I am not rooted and I am using a Simple Mobile SIM card, running Android 4.3.

you more than likely change something unknowingly...
i did that once back in the day, with 'auto-answer mode'... Lol
didn't know why calls wouldn't come through for the longest time, then with enough playing around in service-mode, i found the option and changed it back. Lol
I'm unsure as to if there is a way to change all those settings back to default...
maybe the samsung flash tool would have something for this...
Personally, i would peek around in service mode, and try to deduct from the available options as to what might have changed, based on how comfortable you are with the options though, that might not be a good idea... google is a helper.
all else fails, if you can't use any warranty services for the device, they checking in the phone-specific forum and seeing if someone with the same/similar device can post their settings relative to the mobile network.
good luck
Hey, so 9 months ago I had the same issue that probably has a different cause now. Back then, I used to get the emergency calls only error and my efs was corrupted because of flashing CM13). I fixed it by restoring the nv_data backup I took. Now, I get the same **** all over again, except this time; I DID ABSOLUTELY NOTHING. NADA. ZILCH. The phone went off on it's own, along with the very ability that classified it as a phone.
The IMEI number hasn't changed at all. I mean why would it, I did nothing that could cause this. Flashing new roms doesn't fix this, and neither does that mystical voodoo **** (reinserting the sim-card so many times that you see gold contacts in your sleep). Oh, and I lost the SD card with the original backups on it.
Whenever I try to connect to a carrier by the network operators screen, it just times out. So is there anyway I can fix this? Or at least PINPOINT the problem so I can fix it?
Oh, and there's a thing going with the IR blaster too. It's dead. How would I go about changing the blaster out? It doesn't seem openable like the S4 I had was (metal frame).
Bump
bump once again
Oh come on, nobody has a clue?
Hi @Peontikos_Desmos, actually I have the same problem as you. I have a Korean note 4 n916k and since 1 month I have this strange problem too. I tried everything I know, reflashing original roms from Samsung(android 5.0.1, 5.1.1, 6.0.1), many custom roms ..., ... No way, no solution. The only thing that I tried to make my phone working as phone is just put the network mode in setting to 2G, not 3G, nor 4G, just 2G. With 2G only as network mode, the emergency calls only disappeared BUT now I can't connect to 3G and 4G anymore. Please please help us guys.

so this is the second S7e and second SIM that I have been having this issue with. The phone will lose connection to the mobile network and the ONLY way to recover is to reboot phone. Reset Network Settings doesn't do anything. Toggle airplane mode doesn't do anything. Search for Network Operators doesn't do anything. I have a third phone on the way - but has anyone around here heard of or experienced similar? Am I missing something that I should be doing to correct this?
Thanks in advance
I too have this problem. Got a replacement refurbished phone under warranty and the phone has this problem

Did you pay the $20? I didnt want to pay the 20 so i sent the device to samsung. Should get it back friday or monday. The issue is definitely phone related. Im using a verizon s7 now and no issues like that arose. I even tried new sim.. My father is having same issue t-mobile s7 edge
Yes i had to pay 20. And it's disappointing I am having this issue with the replacement phone. I am having this problem on the U firmware as well.

I've suffered the same issue from time-to-time and just do a restart....annoying as hell to be honest
Are you guys always in the same location when this is happening or is it just whenever and wherever? Or is it happening a one certain place where cell signal isn't that great? I had this same issue BUT only in my house so I had to get a network range extender from t-mobile to use at home.
This happens to me all the time. It's so annoying. At work, in the car, at home--it doesn't matter where I am. Have reset firmware multiple times and even rolled back once too. I think it has to do with the latest software because I never had this issue before the Fall/Winter. Hopefully Nougat fixes this!

I happens randomly in different places. For me i lose complete signal, and then only get back signal without data. I have to restart when this happens to get back data. Annoying as hell !

I am having the same problem, this will be my 3rd phone 4th sim. I wish I knew how to fix it
I would try flashing different radios/modems, its worth a shot. Maybe try flashing the "U" firmware radios.
Nougat will fix it
My wife and I had the same issue on our tmobile s7 edge ... we got the 7.0 beta and now the issue is gone .... I bet it's radio and software related ... 7.0 will be out by the end of the month hope that helps...
I had this issue with my phone, and it was a huge pain. The biggest concern: I didn't know when my phone was off network (voice, data, etc.). The fix, for me, was simple: a new SIM card.
You may have an issue from a rejected permission on an app.
Had the same issue before but I did a hard reset and realised that I changed permissions on an app that wasn't written for 6.1.

I hope so! Been waiting for that before I try anything drastic, even though this issue is a huge pain in the ass. I'm glad others have come out of hiding to express their concerns with it as well. I thought I was the only one for the longest time having this issue.

Many of us have tried new SIM cards, but it's worth a shot if it's still not working consistently after Nougat is released.

My and my friend's phones are both running pure 100% OEM Tmo stock without any apps disabled or touched at all and we have this issue and have done multiple resets. Pretty sure it's an actual hardware defect, or hopefully just a software one with the modem/radio.

I was thinking about going that route. But I wasnt sure what condition the phone would be. How was you condition?
I sent mine to samsung and the things they replaced is the Coaxle cable "antenna" replaced 3 of them. I have been using the s7 from verizon on the U firmware so havent seen if it is fixed.

I received a refurb. Other than this problem, the phone is alright. I noticed this problem on receiving the phone it was running on T firmware. Then I switched to U firmware and radio but no difference. I called customer support yesterday, they said to go to a retail store to get the phone replaced. My worry is going through this process again and if I receive a bad device again what to do? After all refurb phones are like playing Russian roulette!

I just had this start happening on mine... I really wish they would release nougat already. It is ridiculous they won't post an Odin flashable version of the release candidate if it does indeed fix the issue.
I also think its a specific tower configuration that is causing the issue that the radio can not understand. (Maybe 3xCA). Its happening in the same areas every time.
I just started having this problem in the past month. All at once I've been getting BT sometimes turning off, mobile networks failing to reconnect after I visit a no/low signal area (such as after a plane trip when the phone was in airplane mode). I've also seen wifi mode fight my attempts to turn it back on sometimes - toggling itself on and off a couple of times per second until I poke at enough settings to stop it. When BT turns itself off I have trouble turning it back on, sometimes it just goes back on, sometimes it refuses after a number of tries and if I wait an hour it goes back on just fine.
The folks at a BB Samsung kiosk said they could reflash it if I wanted to go that route, but that the nougat release would be out soon so it might be better to just wait for that. Has anyone had a Samsung rep re-image their phone to try to solve this?

If you were able to fix without a reboot you didn't have the same issue as this.

I guess I wasn't clear about that as I have several problems that are probably related, but behave a little differently.
BT dropping - can usually turn it back on, but sometimes it refuses. Usually don't need to reboot to fix this.
Wifi dropping - often have trouble turning it back on and have seen the widget toggle off and on repeatedly by itself. Sometimes have to reboot to fix that.
Mobile Network data (and voice sometimes) dropping - usually have to reboot. I think I may have recovered that once without a reboot, but the other few times it's happened in the past month since it started I have rebooted and that fixed it in all but one of the reboots - one time I rebooted and still had to fiddle with it a bit after the reboot before it came back. That may have been because I played too much with the network settings before the reboot and so had to undo that damage after the reboot. But, definitely rebooting is a fairly reliable step in fixing this problem.
All 3 started happening around the same time which is why I thought it was a software issue (I remember a small update a little over a month ago, but forget the details of it). It's nice to hear that others also have the mobile network problem, but if that is isolated in those cases then maybe I'm not seeing exactly the same problem. But, it is clear that rebooting is almost always required to get my mobile network data back so that again suggests that at least that part is the same as what this thread is discussing.
In looking at the T-Mobile updates page for the S7 Edge I see that the version I have (G935TUVU4APK1) was updated in early November - which tracks when I started having problems, and it includes a fix for "Domestic data roaming improvements", which definitely sounds like they may have played with the radios.
I am so ready for the Nougat update...
So I have a Huawei p8 gra-L09 with Huawei P8 [ROM][6.0] fRomFuture - Home that I installed a couple of months ago. Everything has worked perfectly up until recently when my phone does not find any 3g networks, only 4g. When I try to make a call it's stuck on 4g. I don't even know if my phone is the problem or if it's my carrier. I tried to call them, they said they "made the network better".... But the problem came back after 1-3 days again.
Can I solve this somehow? My phone is also rooted but that doesn't really matter I guess..
Check the fRomFuture thread, another guy in that thread has the same issue..
did you managed to get the issue resolved?
Well, nope. Turning of 4g sort of fixes the problem I think. The connection drops sometimes but most of the time it works. Also I changed to stock b392 because I could not turn off 4g in the build that was used in fromfuture - home for some reason. It automatically turned it on just after chabging to only 3g/2g.
Still doesn't work as intended though and I am 99.9% sure it is not because I don't know how to flash. Used adb and fastboot and unlocked bootloaders and whatever on so many phones since my first smartphone (htc wildfire).
Are you by any chance Swedish or scandinavian? Could it be that it is not compatible with the networks in some countries or something?

No i am in UK; i bleive the single sim version supports all the bands, at least here in UK; it is a phone i just bought off ebay and i can return it but I wanted to be sure it wasn't something that could not easily be fixed before doing so.
Hi again. I have sort of figured something more out about the problem. This morning 3G did not want to work again. So I googled, and googled and googled. Tried everything basically. Then I noticed that my APN settings are not what they were last time I set them(???). So I went into my carriers website. Set the correct apn values and removed any unnecessary values that did not seem to affect anything. Then it immediately worked again. Now I have no idea how phones sets the default settings but it seems like they are wrong? Maybe this was just random that it started working after applying the correct settings again. No idea, going to see if it works all day or if it randomly stops working as earlier.
Edit: 5 hours later still works and the connection hasnt stopped randomly.
Ok so it has worked for 13 hours. It's actually weird if the APN settings for 4g broke the 3g connection sometimes randomly throughout the day, right? I don't know how apn settings really work but I remember setting a port number and also changed the name of the APN so that I can be sure it does not change to something else.
ugh, I give up. Now it stopped working again since yesterday. It feels like it's my carrier but so many people have this problem so I guess it's something else..
Nevermind I don't give up. I found a solution . When 3g/calls stop working the phone usually gets really, really hot. So putting it in the freezer for a couple of minutes actually fixes the problem for me, atleast until the phone gets really hot again. I have tried it four times now and every time it has worked.
Is anyone having this issue.
I upgraded to android 8.0 and no longer able to get any Verizon LTE service no matter what location I am in. I get frequent notifications stating I am Roaming and my phone is not rooted and the bootloader was locked, yet Android Pay Pop ups stating it cannot work on my 6p because my phone is either rooted or the bootloader is unlocked.
I flashed several different images to no avail.
Advice?

Reset Network settings reset, wipe cache partition. When you say you flashed images, do you mean sideloading OTAs.... or are you unlocked and using full images? Your post led me to believe you were getting erroneous messages about being rooted/unlocked (meaning you were not).

Tried it all.
I installed several full factory image versions, locked the boot-loader and then started up the phone. With the boot-loader locked and phone not rooted Android Pay still gave me the error that my phone is running a custom ROM, the boot-loader is unlocked or the phone is rooted.
I have also installed several OTA images and none of the problems I mentioned in my earlier post went away. The only way for me to get Android pay to work is to unlock the boot-loader and root the phone with magisk. However, I still get intermittent Roaming notifications, intermittent signal lost and no LTE whatsoever.
Today:
I called Google and and did 45mins of troubleshooting, the final thing we did was reset my phone and then the agent acted helpless when nothing resolved the issue.
I called Verizon did 30 minutes of troubleshooting with them, reset network setting about 100 times, turned off my phone so that they could re-provision on their end. Turned the phone on and got LTE signal for approximately 60seconds. Then it went back to 3G, then no signal and then the dreadful roaming notification every few minutes.
Are you using the stock recovery or TWRP? And when you installed factory image did you do it through your computer using flash all? Or did you just install the factory image? Personally what I would do if wipe everything out and use your computer to install the latest factory image using the flash all script. So you are completely stock then relock the bootloader. Then you should be completely up to date with modem bootloader recovery vendor and rom. Your lte issue sounds like a modem problem possibly. And the September security patch broke safety net check and therefore Android pay. That build ended in.017. there is a new one up that fixes those issues and I think also the issue with the phone choosing mobile data over WiFi when it should be choosing wifi over mobile. That build ends in.019. try installing that build like I said above. Good luck

I wiped DATA so there were no files on my phone.
Downloaded july,august,september factory images and flashed, locked bootloader and tested each image to no avail. I saw the build on the google forum for 019 so i flashed that as well and same sh:silly:t different day.
Last thing I did was to flash 7.1.1 and that did not resolved my problems. Got the OTA notification to install 8.0 hoping all my problems might disappear but they did not.
It has been an hour and LTE seems to be working again
I have a 5X on Project Fi and my 6P is on Verizon(the phone that is having problems).
As a last resort tonight I swapped SIM Cards and after a few minutes the Fi SIM in the 6P showed LTE service. (Maybe proof it was not the phone....??? who knows)
It took alot longer but my Verizon sim then showed LTE service on my 5X which is running Oreo btw. (Baffled at this point)
I placed the SIM cards back in their original phones and LTE is functional on both. On my 6P I enabled WIFI, downloaded data, toggled WIFI, rebooted, ran several speed test and the 6P still shows LTE and I haven't seen the dreadful roaming notification as of this message.
I guess problem solved. Now to install Magisk to get AP working.
Wow that is odd. The one thing I have noticed with 8.0 on my 6p on fi is sometimes I lose data when I'm out and the phone loses wifi and switches back to lte. I have to reset the phone to get lte back.
Thank you so much for posting this issue. My Nexus 6P was doing the same thing after 8.01 October security update. Tried everything, same as you listed. I found your post and recalled that during my initial setup I had to put my wife's Verizon SIM into the 6P due to the same issue occurring. I tried it again this time but it failed, issue persisted. So, based on your post, I got a Project Fi SIM for $30 (1 month) and just tried it again. Powered down, put in Fi SIM, power on, activated Fi (with new phone # for new line... will be cancelled if needed...), and got LTE without issues over Project Fi. Then, I did Network Settings reset, reboot, and powered back up. No issues with Fi.
So, to the point now. I put the Verizon SIM back in the 6P and BAM, full LTE, no issues. Whatever the non-Verizon SIM does to the phone internal settings I have no idea, but I can tell you that it was not a fluke that your process worked. The exact same thing worked for me.
Hope this helps anyone else with the same issue - you need to install a non-Verizon SIM, get LTE going, and then put the Verizon SIM back in.
Thanks again.

Just my 2 centers here for anyone else in this quagmire...
I had same issue. I've got a Nexus 6p on which I dirty flashed an 8.1 update of ABC Rom over an earlier 8.1 version of ABC Rom. After that, the issues began. At boot, I'd be on 3g and if I toggled airplane mode off and then on, I could get LTE for about 10 seconds. However, it would then drop back to 3g. I tried everything, as is stated above: revert to stock, older radio images, different SIM... nothing worked. I read about people manually configuring their APNs. However, I've got a Verizon SIM, so that option was gone.
Anyway, after reading this post, I got the idea that I might be able to mimic the solution without buying a Project Fi SIM that I don't want.
Here's what I did:
Open the Phone's Testing Settings by dialing: *#*#4636#*#*
Tap "Phone Information"
Scroll down and set the "VoLTE Provisioned" toggle to the "on" position.
Then, toggle airplane mode on and off.
Profit!
I'm not sure if this solution has any parallels to the solution that uses a project Fi SIM for a brief moment. However, I speculate that it may.
At any rate, I hope this helps someone else with this issue.
UPDATE:
It turns out this method is more of a work around at best. At first I noticed that I had to toggle airplane mode once after a reboot. That didn't seem too difficult. However, I then discovered that I could no longer make calls. Switching the VoLTE Provisioned toggle back off fixes the calling issue, but puts me back on 3G.
Uggg.

Hey is ur 6p still running well with LTE? I did that with a att SIM card and my 6p read as a att SIM so I then put my Verizon Sim back in and it read Verizon LTE but then after like half an hour it changed back to roaming and 3g. I went to Verizon to get a new sim card but that didn't do any help at all. I would like ur feedback if possible. Thank you

Hey is the 6p still working well for you? LTE? I been following ur steps but I don't have project fi and I used my friends att SIM to kinda reset the network and I also reset the network too but it went back to 3g and roaming. Any help would be awesome. I don't want to have to get a new phone

Hello. I have not had any issues with the 6P since posting this. I honestly can't explain why the method posted earlier works, there does not seem to be a visible change in the user accessible settings.... so i don't know if i can help you any further from a technical standpoint. I'm not sure why the Verizon SIM didn't fix it the 2nd time, in my case. Something to do with the internal calibration of the LTE antenna (i'm guessing).
If you're willing to go this far, a factory reset of the phone, then ATT SIM might be an option. I HAVE NO IDEA IF THIS WILL WORK, so take that advice with 'a grain of salt'. Something to consider if you don't mind resetting the phone but don't/can't get a Fi account.
I can say that it was worth the $30 to me for a Fi account since it fixed it, but maybe more importantly the knowledge that if it happens AGAIN I should be able to fix it.
I know that wasn't super helpful but that's been my experience since the post.
(unrelated, but since you're a 6P user you may find helpful, I had the dreaded early battery shut down and it got so bad it almost bricked my phone. I got a new battery by sending it to Huawei customer service and it works like a champ now. Better than when it was brand new, from a battery standpoint.)

I can say that it was worth the $30 to me for a Fi account since it fixed it, but maybe more importantly the knowledge that if it happens AGAIN I should be able to fix it.
I know that wasn't super helpful but that's been my experience since the post.
(unrelated, but since you're a 6P user you may find helpful, I had the dreaded early battery shut down and it got so bad it almost bricked my phone. I got a new battery by sending it to Huawei customer service and it works like a champ now. Better than when it was brand new, from a battery standpoint.)

Tea I bought a new battery on eBay for 10 and got it replaced and it's running awesome. Are you on a custom rom? Just wondering what else I can try to fix this. It's weird while on the att it worked fine with LTE. I'm thinking about getting a fi acct thought

I had this same exact issue... I'm on Verizon and I was running FireHound ROM, which I loved btw, but every time I restarted the phone/toggled airplane LTE would pop up for 30 seconds and I would be stuck on 3G. Huge bummer but I found this to be an issue on every current custom ROM. Defeated and abused I ended up returning to 100% stock, unrooted and locked bootloader, full LTE capabilities now. I did end up buying a new SIM which helped with some of the connectivity issues I was having before granted my original sim was cut twice and I had it for many many years. Try going 100% back to stock, replace your SIM(most places cost about $10) and you should be good to go. I can only chalk this up to be an issue with source provided to developers but I'm not sure where the discrepancy lies for DEVS that isn't consistent with a stock instal...
Tried all these ROMs:
FireHound
ABC
Resurrection Remix
DARK ROM
Cortex - Uneffected by the LTE issue but is a dead ROM as of now and is on a different vendor.
