Hi there,
I need help. I am on a NZ Note 4 N910U. What often happens is that my phone prefers or "hangs" on low 4G reception instead of changing to 3G or HSPA+. While this is occurring SMS fail to send constantly until it decides to change down to 3G.
Has anyone else had this problem? My carrier is having difficulty accepting this as a problem because the SMS that fail to send apparently do not show up on their servers and I am currently at a stalemate with them over this.
There appears to be some spotty coverage of this type of issue on the internet but nothing with a solution.
I have tried a logcat but it only seems to show that the messages fail.

I am on an AT&T 8525(see signature) running WM 6.1. I am in an area where my phone shows that I am on AT&T's network in the southeast US with 2 bars but I have no service. I cannot make a phone call although I occasionally receive a call, I cannot answer it. I also cannot get any data connection to work except the occasional SMS message. My wife is on T-Mobile with an 8125 and she has about the same coverage although she can make and receive calls about 90% of the time so there is no doubt that we are on the fringe of coverage.
I've tried changing the network band on my phone with no luck(trying to see if for some reason T-Mobile is on something different than AT&T). I tried upgrading my radio ROM as well to see if that would help(see sig) but didn't change anything. In other areas, with just the one bar of signal strength I've been able to make calls 100% of the time. It's only this one area that gives me fits.
I have FieldTest.exe on my phone but must admit that other than looking at the pretty numbers, I don't really know how to interpret the results of that app. Any suggestions?

I am having same problem, tried something like 3 roms , and it sometimes work for a while then stop working again, i was a new rom when i found it was making calls but no 3G connection, i tried another rom, made few calls then now it is unable to connect to anything , please let me know if you find a solution
Sprint LS980
Looks like most of my issues have been solved so far with this phone except for the fact that sometimes when a call comes in (or sometimes even out) the hand off between the 4G network to the 3G network is either very slow or doesn't take place; as in I get missed calls with a full signal or the phone gives up and makes me roam even though I have a full Sprint signal.
Anyone else have this issue or could offer any advice on a fix for this?
Are you aware of this?

Unfortunately I have read that article before. It does look like all of the towers in my area were upgraded last month and the service bulletin confirms this. Wasn't sure if anyone else was experiencing a hand-off issue; doesn't seem to be there when I set the phone to 3g only...
Hi All,
I have a Galaxy Note 4 SM-N910F with BTU firmware N910FXXU1ANK4 (UK) which I flashed from the older O2 UK firmware N910FXXU1ANJ4 when I bought it.
I am having problems receiving calls and making calls when 4G LTE is enabled on the phone (I get 4G signal bar). When someone calls me my phone rings and the signal bar is 3-5 bars usually and when I slide to answer the phone it seems to answer (timer starts clocking up) and I can't hear anything (sometimes for a split second) and the other person can't hear me, then the person is directly kicked to my voice mail!
If I try to make outgoing calls with 4G enabled it sometimes works but other times it sits there saying "dialling..." then after 10 second or so gives up and stops. If I do manage to call out I get terrible phone recetion breaking up and high pitched noises sometimes. Sometimes it is ok for a while talking but eventually the call drops at some stage.
If I force my phone into 2G only or 2G/3G only then the phone seems to work completely normally.
I have had multiple SIM swaps with no luck.
Samsung walk in repair centre was useless as the empolyees all appeared to be undertrained kids.
O2 was no use saying there is no transmitter faults reported in my area.
Before I try a hard reset and flashing back to the old O2 firmware and then possibly sending my phone away for repair, is there anything else that might be going on here? Has anyone else seen this or know if it is a known problem?
Cheers,
Richard.

Most mobile providers still don't support VoLTE (don't know if that is the case in UK) so your phone needs to go down to 3g/2g when phone call is received.. So maybe there is some problem between BTU and O2 firmware (I am no expert, but may be CSC related)..
I suppose your network selection on 4g/3g/2g automatic mode, not LTE (4G only)?

I only have the option of :
LTE/WCDMA/GSM (auto connect) - Have the issues with this mode
WCDMA/GSM (auto connect) - No issues in this mode
WCDMA only - not tested
GSM only - No issues in this mode.
In phone dialer hit settings. There should be a volte toggle if there is turn it off.
I don't have any issue like that. 4G turns to 3G or 2G when receiving/taking a call. May be u hav an issue with ur firmware
I've tried flashing back from the BTU UK firmware back to the original O2 UK firmware and the problem remains. I also tried a hard reset afterwards leaving the same issue.
I have noticed that the issue does occur with 3G as well as 4G but it seems to be a bit more stable. 2G seems the most stable.
I have arranged with Samsung to send my Note 4 for repair so hopefully that will resolve the issues.
I have the same problem using 4G. Sent for replacement. Waiting for feedback..
got information that warranty service did find the problem and in a week or so I will get new one
I HAVE THE SAME PROBLEM!!!! THANKS A LOT !!!!! I WAS LIKE CRAZY TRYING WHAT CAN BE WRONG WITH THIS....
In my situation i can
send and receive sms on all mods
I can call in 4g but i can't receive calls when im on 4g... - just only hire is a issue
Last time my charger when i was charging in night get burn and i think meybe form that time... i have phone 3 weeks brand new.
Greetings.
I bought a new imported LG G2 from Germany, at least I think so since it has paperwork in German.
I live in Lithuania, one of the Baltic countries.
And my signal seems to disappear from time to time, maybe it's because it switches to GSM/WCDMA from LTE and vice versa?
And other annoying thing is that I receive messages from my sim card carrier that I have no money left to browse the internet. It's an automated message when you have no money left in your sim account so it means my mobile data is being used somehow but I have it disabled.
..Anyone?
My G2 randomly loses signal for at most 30secs before reconnecting to LTE or hspa+ on T-Mobile. This happens randomly even when signal strength is high, therefore it could be a hardware defect or hopefully a bug that LG can patch with a new modem.
As for the messages from your carrier I believe those service messages are handled by WAP Service/Push (system app). But check the messaging app for the setting that controls service messages.

The problem was probably not with the phone (Unless it's something with LTE modem) but with my signal itself.
The LTE signal is really low here so the phone disconnects from it a lot, resulting it switching to other signal and being disabled for few seconds.
The fix was to go in to mobile data settings and disable LTE. Now I'm not losing connection and neither I'm getting messages from my carrier about the internet.
From the beginning, I experience this issue and it is really a dealbreaker. A phone's main and most important feature is to make and receive calls... I constantly miss a ton of calls almost every 3/5 calls are missed. To the people who call me it says that I am outside network coverage or the call cannot be completed at the moment. At the same time I look at the coverage on the phone and it displays FULL coverage + 4G mobile data running without interruptions. When I try to call or return the missed call I don't have any problems at all. I live in Eastern Europe, the bands seem OK, they are according to the EU standards. Does anyone else have the same problem or does anyone know how to fix it? The OTA updates don't help for now, nor changing the SIM slot.
