No Service for a few seconds, happens all the time

Hey everyone, just another thing I'm facing with my Note 4...
Ever since I got my Note 4, it's been having some problems with No Service, so I thought it was my old SIM card (that had to be hacked off into microSIM shape), but since I got it exchanged for a new one it's still dropping into No Service very often, like twenty times in 5 minutes. Then it seems to be fine for a few hours, but then it happens again a few times and so on...
Basic info:
SM-N910F
Stock, unrooted NK4 ROM with NK4 modem as there is no way to not trip KNOX yet.
O2 Czech Republic
In the same places, my S2 never had a single signal drop (No Service)—not sure if these two things are identical?
Questions/thoughts...
Could this be modem related or could it be something with the device itself?
Is there any way to test it?
I mostly notice it on H and H+, not so much (never) on EDGE, 4G coverage is rare in my area, so I can't say exactly.
Factory reset: could it change something in this case? I'm saving it as the penultimate solution, before getting a new one.
Thanks for your help.

I think I found a little bit of correlation between when and where it happens. Not really sure if it happens only when I'm close to some WiFi network, but I just noticed that when I'm in proximity of a WiFi network, the NO SERVICE is very often.
Plus, when I think about it, I haven't noticed it anywhere else, but in WiFi areas. Is the phone trying to tell me to use the WiFi?! Well, I can do that at home but nowhere else as I don't want my packets sniffed more than they already are by the provider...
Seriously, is there any way that WiFi networks could interfere with my phone's signal/service?

if smart switch is on, yes.

Thank you for the reply, I thought that smart switch was meant for transferring data from an old phone to a new one? Or do you mean some different "smart switch"?

look in settings. smart switch moves data from your mobile network to wifi and back.

Yeah, found it, Smart network switch in Wi-Fi settings. I have it unticked. So this shouldn't be affecting me(?) As the No Service happens to me when I'm on mobile data, in Wi-Fi range but my Wi-Fi is off...

no solution yet
I still haven't figured out what's the problem exactly.
But me and my colleague have the same provider, but she's got an S4 and when I had them side-by-side I noticed that both phones dropped to No Service at the same time, but my S2 didn't. The area is fine, signal-wise, there's even a mediocre 4G, but at the time all of them were on H+. And when they "regained consciousness", they were starting from zero signal EDGE back to full H+.
This makes me wonder, as it seems it's got to have something to do with some setting in both phones / SIM cards' setup. Both of them have new SIM cards and both of them did it even with the old ones.
I'm gonna call my provider's tech support to see what they have to say about it.

I am experiencing the same problem here in USA. I bought the phone from Amazon Germany, using it on AT & T network in US. For no reason the phone drops the phone call and goes into " Not registered on network" message. This lasts anywhere from 20 seconds to 5 minutes, then without me doing anything goes back to normal. I was using this phone in Czech republic for a week in January and had no issues.

I was experiencing no service on my Exynos n910u and I ended up reflashing ONLY the modem, and it's fine now.

Hey guys, thanks for the replies.
It seems to me like a modem issue too. I remember that I had to change modem on my S2 in order for H+ to work.
And since I can see there is an issue when changing countries, it would suggest it as possible... However, does flashing modem only trip the Knox counter or something? I can't read through the forums right now, so I'm asking politely here.
Anyway, I isolated the issue to 3G networks, because when I force my phone to be 2G only it never drops, my signal is green and seldom grey. No service never occurs, but as soon as I switch it to 2G/3G/4G or something else that includes 3G, it starts again.

Wanted to thank you for the input, this just suggests that the modem/radio is at fault. Because you relocated to a different area and it doesn't work properly with the bands there.
I had the same problem on my S2, which was unable to connect to 3G until I flashed the modem recommended to me by someone here on xda. But that was almost 4 years ago, I just don't understand why this happens, what's so different that the modem just wouldn't connect, plus the S2 was bought from my provider and it was branded with their bloatware and still, it didn't work.
But here on my N4, it's similar, but it seems to work just fine and then, all of a sudden, you're facing No Service message for a few seconds or minutes, then boom, you're back on.
I spoke with Samsung support today, and I guess they didn't even understand what I was saying. I'm gonna have to visit them and ask around, if they could flash the modem to something more compatible with my area. Can't use the phone like this, that's why I bought it in the first place - I need to be online and as fast as possible. But now, it would seem like I'm better off with my S2

Well, that sucks...
So, I had my phone serviced and they said everything was fine and that it's working the way it should.
Of course it isn't, the second I walked out of there I had a No Service a few times again, I already tried changing the bands only to what my provider has, didn't help at all, switched it back to all available bands. Naturally, I got really pissed. There seem to be only two viable options:
a) flash a different modem, as suggested in a previous post
or
b) get rid of the phone, which I really don't wanna do, but it's really annoying having to resend every second message (often twice), be it SMS or IM, because it drops into No Service...
ad a) I did a search and I was unable to find a modem thread or anything regarding modems for N910F, am I blind or there isn't one? Or am I supposed to extract it myself from a stock ROM file? (I don't even remember how to do that anymore, lol.... I guess there is a guide for that, but again, I haven't found it?! Or is it universal across Samsung devices?)
ad b) I love the phone but this makes me wanna throw it out the window
Thanks for any kind of help! I'm desperate.

Thank you for your reply!
I haven't solved them yet, but it got a lot better when I updated to Lollipop. It's got a different modem (BOC4) and it seems to have improved my situation. So happy I didn't have to throw the phone away after all.
To be clear, it still happens but a lot less since the update, maybe once a week, for a few seconds which I deem acceptable but not ideal.

I took my Note 4 and a hammer into the garden today...........

I took my SM N910L Note 4 and a hammer into the garden today because no matter what I've tried
(and I've tried everything http://forum.xda-developers.com/note-4/general/im-bonkers-ill-pay-50-dollars-to-fix-t3169748)
I just can't get it to work. I put the Note 4 on the grass and I raised the hammer above my head - but I just couldn't do it....... it's not the money......it's the waste.............
So, I'm upping my offer. If you can tell me what to do to get my NOTE 4 receiving and sending DATA again (basically connecting to my carrier) I'll send you 100 dollars. The first person to to show/tell me something that allows me to make a skype call or receive even 1 email through my DATA connection gets the money. INSTANTLY!!!!!
Please read the thread above, all the info is in there except this. I have been trying to flash a different custom ROM in the hope that that will fix it but none of the ROMs I have downloaded will flash thru TWRP (even though I can backup and restore thru TWRP). I get an error message saying unable o open zip. Anyway, if anyone has any ideas please post.
A very big thank you again to all those who have tried to help me already.
I have a hundred dollars pinned on the wall in front of me .................. I'll be sooooooo happy to see it go !
P.S. I know that you are not helping me just for the money, I know you are helping just to help me out (and I have had so much help already), but I just want to make it worth your while too.

Is it the modem? Perhaps try installing the official docomo 4.4.4 rom for the note 4 via Odin. See if that fixes it?
I'm a noob but it's all I can think of. I hope it helps somewhat and if not then just return the phone?

I think it is the modem too, but I've re-installed 4.4.4 and 5.01 many many times. I flashed individual modems too. Nothing seems to sort it out. Can't return the phone - bought on Amazon from Korea, seller sucks, Amazon unhelpful, that's a dead end - I need to fix it.
Thanks anyway (I'm a noob too )

Might sound stupid, but have you tried a different SIM card?

load stock rom on it for the 910L with all stock CSC, do a complete reset, turn off carrier data in settings, select carrier network manually then turn on wifi carrier data bluetooth. make sure smart network switch is off. disconnect wifi and try it out.
and if that doesnt work ship me the phone instead of using a hammer on it lol.

Have you called your carrier to make sure it's not some sort of problem with how they have your account set up?

Yup I have 2 sim cards now with two different carriers and have spent hours and hours on the phone with them both trying to work out why it is not getting data. My only glimmer of hope is that although they are different carriers I have found out that they both use the same network (dohhh) so maybe it is specific to that network - DOCOMO.
thanks for your help.

OP, does Settings -> About Device -> Status show that Data is In Service?

If yes, you probably have some sort of APN issue with Docomo. If not, you may be boned.
IF YES:
Go to Settings -> More Networks -> Mobile networks -> Access Point Names
Press the plus symbol on the top right, set the name to DOCOMO, set the APN to mopera.net, set the MCC to 440 and MNC to 10.
If this doesn't work, use 0120.mopera.ne.jp as your APN instead.
If that still doesn't work, have you tried a b-mobile SIM? I had this issue once when I was in Japan for some time - Docomo doesn't like people using unlocked, imported devices on their networks for some reason.

Yup, I think that it is about time. Hate doing it because Im sure it's a software issue, but I don't have any more avenues to go down now. But it will cost more than a hundred dollars though - I live in Japan, I'll be lucky if I get out of their spending less than 200 dollars. Still, let's see.

Talked to Samsung Japan today. They wont fix try to fix it even if I offer to pay - has to go back to Korea. The company I bought it from said it is user negligence, Amazon says it was working for 7 weeks so it is not there problem.
So, seems I'm left with a very pretty, extremely useful Samsung iPod. No phone though.........................
At some point it is stupid not to give up...................

Seriously considering saying yes
At this point I'd consider human sacrifices, voodoo dolls, or crystals too.

Are you sure that SM 910L is your local Note 4 variant? There might be hardware differences in different variants that only accepts certain signal bandwidth for a specific carrier.

Nexus 6p no longer works on verizon after using with vodaphone sim card on a trip

Hi all,
My 6p that used to work great on verizon can now no longer make or receive voice calls, even though 4G data works!
I have been using my 6p on a verizon prepaid plan for months, and it has worked flawlessly. I popped a sim into an S4 to activate, then put the sim in the 6p, and everything worked great.
I recently went out of the US for a week. Verizon prepaid doesn't work at all in Europe, so I bought a tourist SIM with some data to be able to use my phone while traveling. Again, this worked great.
When I got home, I put my old verizon sim back in my 6p, expecting to go right back to where I left off. The problem is that can't make or receive any voice calls on the 6p. Whenever I try to make a call, I get a verizon message asking me to enter the 10-digit number again. Incoming calls are going right to voicemail. SMS works fine though, and 4G LTE works fine -- just no voice.
Verizon tech support is no help. They say that if I use the device on anything other than verizon's network, it has been flashed and will never work again fully on the verizon network, which is obviously BS.
I have tried putting the sim card back in an old S4, and voice calls work fine there, so I know it's something with the 6P.
Any ideas on a setting that I might need to change on the 6P to make it work again? The Vodaphone person took my phone for a second and may have made a change or two that I didn't see to the settings? :/
Any help is appreciated! I use this phone for work, and if I can't get this resolved soon then I guess I'll just have to switch to tmobile ASAP.

I'm on Verizon and Every time I use a project fi sim in my Nexus and then go back to the verizon sim...the verizon sim doesn't work any more. I have to get a new sim every time. I think it's just the way Verizon does sim card management on their phones.

Thats where your problems at. At the bottom mine says LTE/CDMA auto prl does yours say the same? If not you need to change it. If that doesn't help you can hit the 3 dot menu on the top right and click on band 6. It's possible your network band was changed. I had this problem after mistakenly changing mine to USA band.

I actually went to verizon and got a new sim and still no luck. Verizon is crazy. I'm about to just switch carriers.

I changed it to LTE/CDMA, but it couldn't find any service at all under that option.
On the three dot menu, weirdly I only have US, Cellular 800, PCS, and Class 10 (800mhz secondary), but no class 6.

It sounds to me like your radio bands were modified. You can try flashing your radio again in fast boot or install a custom ROM like chroma that has a lot of extra bands to choose from. A while back I saw a thread in this section where someone had made a zip you can flash for this same problem also.

I had a similar problem with Sprint. Text and data worked fine but no calls. Might be a CDMA related problem.
Mine was caused by me changing the band the "USA" in the phone info (*#*#4636#*#*) menu. I had no way of getting it back because whatever ROM I flashed I never had the "Auto" band option. The Vodafone guy may have changed your phone's banding to Europe and for some reason it's a pain to change it back. I ended up complaining to Google and they allowed me to RMA the device.
However, I saw this thread later which may help fix your problem. Flash the ROM from that thread and go to the info menu and click "Auto".
Good luck.
Edit: Found another thread here describing the same or similar problem and the above fix worked.

I started having the same problem today, with my wife's 6P and my daughters 5X, it turns out the HD Voice feature from Verizon was my problem, since that was the only thing I had modify before they lost phone call capabilities, I went back to the Verizon website and under "My Products and Apps" you are able to disable or remove that feature, I then rebooted each phone and they are able to make calls again. Hope this helps someone.

Sorry to bump an old thread... I've run into this exact same issue. I've tried the rom in the post above - had lots of errors of services stopping but eventually managed to set it to automatic... nothing helped. I tried another purenexus 6.0 rom and while that works better as far as rom goes, it still doesn't let me place voice data calls.
The only thing that halfway works is enabling HD voice - and VoLTE on the phone. This means I can make phones when and where I have LTE but still nothing over the normal cellular voice network.
Anyone find any way of fixing this?

VoLTE and WiFi calling on Three UK

Hi all,
I grew tired with the lack of VoLTE and WiFi calling on my unbranded, bought direct from Samsung S8 - there's no sign of Three enabling either on unbranded phones.
So I did the unthinkable and flashed the H3G branded firmware - all went fine.
Only trouble is - I have no VoLTE - the option isn't there - and I don't get VoLTE in places where I know I should and have had in the past on my S7.
Three are useless and haven't a clue what I'm talking about. So I wondered if anyone here knows how VoLTE is actually supposed to work with the S8 on Three. I don't have the VoLTE on/off toggle like I did in the settings on my S7 and I don't get VoLTE in places where I used to get VoLTE on my S7. I either get nothing or a very low H/4G.
Is this expected behaviour and are the options just hidden now? Do you still get the little VoLTE indicator as with the S7 when the S8 is using VoLTE?

I was in the same situation, unbranded from Samsung, had to do a full wipe + H3G flash through ODIN and both VoLTE and Wifi calling work.
I had trouble getting them both, until I re-partitioned the phone in ODIN, which was a pain.

I was in the same situation, unbranded from Samsung, had to do a full wipe + H3G flash through ODIN and both VoLTE and Wifi calling work.
I had trouble getting them both, until I re-partitioned the phone in ODIN, which was a pain.

Hi,
Does it now work as described with the on/off toggle in settings? Three basically told me that this is just how it works, any options are hidden and it won't go near VoLTE unless there is literally no other signal of any other kind. Where as on my S7 I had the option to switch on and off plus I got the VoLTE symbol in a lot of places.
Is there a guide to link to regarding the re-partitioning you did?
I'm reading some pretty scary things about the re-partition button in Odin!

Yes, re-partitioning was a pain, I got some bootloop issues as a result so wouldn't recommend it (no specific guide from memory)
I actually cannot see any on/off toggle in settings, VoLTE icon appears on most 4g areas.

I went for it - no problems, carried out exactly the same process only this time I ticked 're-partition'. I've just restored all my apps and had to reset my Gear S3 again.
I also downloaded the small (40MB-ish) OTA update that comes down after the re-flash, which I assume is the VoLTE settings from Three.
So far, all I've noticed is that WiFi calling is a lot more stable - before, the WiFi calling icon was appearing and vanishing all the time. Now it's solid.
No sign of VoLTE - or any VoLTE toggle. I'll see what happens when I'm out and about later, hopefully it'll have worked.
(Although I'm sure I got VoLTE at home on my S7, I might be mistaken. Checking the coverage checker I'm in solid VoLTE territory though.)
I must say, factory re-store/re-flashing is so much better now that the Samsung back-up and restore app actually restores everything properly! Right down to the shortcuts and widgets on your homescreens. I was dreading it.

Does any one mind hosting the three s8 firmware on a store some where like google drive or drop box
PLEASE I could do with a quick download and rebuild of my phone tonight

or even a ftp share (OLD SCHOOL)

I got it from the Sammobile site. You have to sign up and the download is slow, but it does the job.

i was hoping you could share your copy. of course i am downing from sam mobile but its taking an AGE.
i flashed it... no problems wifi calling there but no volte for now.

I've been doing some reading, it seem that the way they have it set up is so that VoLTE is a last resort when you lose all other 3G and 4G signal. So if there's 3G available you'll never see VoLTE (or WiFi calling for that matter).
Also explains why you have to have their firmware and they've blocked access to it on unbranded phones? Because surely with regular firmware, if it's there - the phone will log on to it and they can't control that on an unbranded phone. Or is it controllable by the network?
I wonder why they've done this? Seems odd. Also odd that there's no switch, one of the reasons I hate branded firmware is that they can mess with stuff like that, I hate the idea that they're hiding functions and messing with stuff on my phone, that I paid £650 for! - along with the horrible boot logos and bloat.

Wish they would allow it to work on unbranded phones, I'm running dual sim so no chance of ever being able to install

If you decide to unlock your device and go down the TWRP and Custom ROMS path then feel free to use the attached ZIP to flash the H3G Three CSC to enable WiFi Calling/VoLTE and Call Recording.
I took the CSC utility posted by Tkkg1994 and created a flashable TWRP zip with just the relevent files removing the APK that Three put on when first setting up the phone as well as the Three boot animation leaving the Samsung stock one in place. I did this to save having to have a 1.5GB file on my phone with CSC's that I don't need. All credit goes to Tkkg1994 for the CSC Utility.
I have only tested this on the single sim SM-G950F however and I also recommend making sure you have an EFS backup beforehand as I know the CSC Utility does do that even though this zip doesn't mount and do anything with the EFS partition.
Thanks

That is really silly. EE do the same thing in terms of needing their firmware to use VoLTE but they do not limit it only when you have bad signal lol that is foolish. Funny how things are with different manufacturers. On my U11, VoLTE works for all UK networks with stock unbranded firmware and it even has a toggle, unlike the S7/S8. You'd think there would be more options on the more popular phone.

Use updato.com. no download speed limit

I spoke to three over twitter and they advised they do plan to release this to unbranded phones but there is no date in mind at present

I had to do the same to get Volte on EE.
Does work everywhere though.
WiFi calling worked out the box on BTU unlocked.
Only issue is EE is **** slow at releasing updates.

Is there a file I can flash to enable WiFi and VOLTE on EE when using a custom ROM? Works great on the stock EE firmware but I would like to use another custom ROM.

You have to edit csc files to enable them

Samsung Galaxy Note FE having Operator signal problem.

Hi All,
Recently I purchased my NOTE FE from KSA and was very excited to use this fabulous phone but unfortunately have been facing Network Signal problem. Let me explain what steps I have taken to troubleshoot it.
1. Used three different Operator Nano SIM which are working absolutely fine in Galaxy Grand Prime and Iphone 8 but when I insert it in NOTE FE signals just vanishes after a while when the phone is in standby the I have to turn ON the screen and at times have to change NETWORK MODE LTE/3G/2G , 3G/2G , 3G only or 2G only but after a while again I have no Network it keeps on fluctuating. Due to this reason when I try to call to my NOTE FE the message I receive is that the dialed number is not responding.
2. I have tried both slots i.e. Slot-1 & Slot 2 the issue remains the same.
3. I have also tried to factory reset but the issue remained the same.
Rest all features of my NOTE FE are working fine including WI-FI and all APPS of the phone.
I am very upset kindly If any of you can guide me or tell me what could be the reason behind this. Looking forward to your valuable suggestions.
For the reference please see the attached Pics.

Dear "megamanrave" as per your suggestion I did the above mentioned procedure but issue still remains the same.
Looking forward to further suggestions.

Model: SM-N935FZKDKSA
SM-N935F/DS dual SIM variant
I have tried all carrier Network in my country Mobilink, Ufone & Telenor but the issue remains the same.

Have u tried other apps to fix data connection issues I don't know what's going on other than correct apn setting also what firmware are you on?

Have you used this mobile in KSA before using it in Pakistan??
As it has a sim lock for Middle East & North Africa Sims only, which get unlocked by using your KSA sim for 5 minutes calling.

Yes I did that as well before bringing it to Pakistan I made sure to use it in KSA. Had made calls for more than 10 mins both local and international. Secondly Pakistan is already in Middle-East Region as per Samsung list of regions so in theory there is no need to do that. People from India have to perform this as India is listed in Asia Region as per Samsung.

Try this setting
In sim manager, set network mode to 3g/2g instead of lte/3g/4g and then inform if things solved?
Please also inbox me your WhatsApp number.
I am trying to send you msg via inbox but not successful.

Plz take it to Samsung Service Center and inform them this issue. Goto Samsung KSA website and ask you can do Lice Chat as well.

I agree with the option to go to the service centre. I had the same issue, they replaced the motherboard for me as it's a modem issue. Since then haven't had it recur unless I'm in an area with no signal (partially caused by my thickass Spigen case but that's another issue altogether).

I have the same handset i.e, bought in KSA and using on Jazz network in Pakistan without any issues. So yours need to be checked by Samsung service centre.

Hi Guys, Well I sent my Samsung Galaxy NOTE FE to Samsung Service center in Jeddah and they fixed the Network Signal Issue i was facing before. Now My device is working flawless. AL-HUMDOLILLAH. Word of Advice for Samsung is that their QA needs to improve their department performance before releasing Flagship devices in the market to avoid such issues in the first place.

what problem?
