Change the modem - Galaxy Note 3 Q&A, Help & Troubleshooting

I have a really bad signal strength on my note 3 and would like to try flashing another modem/baseband.
Just wondering if its an risk that all data will be lost when flashing new modem/baseband?

No but don t forget to save efs....but back up is always a good idea?

Try to move to another area or have another phone to compare the signal strength?
I don't think the modem can cause the issue

Absolutely no trolling here, please. I need to choose between lg g2 and note3. Only fear is all the issues I've read about the note 3 signal and wifi. Actually I would like to get the n3 but I live in a poor signal area (also I work in poor signal area) and I really don't want to have problems with signal.Some friend living same block have the G2 and the signal is very good and stable. I gor scared of all the issues read about n3, although it is my favorite.
Please, I need honest opinion about N3 signal strength and if wifi is as poor as many forums stated. Tks....

Yes I have compared with other mobile devices in same places with same provider, suddenly note 3 can drop to no signal when the other devices still have good signal.

Thank you, Indeed very strange signal behavior. I also compared the signal between N3 and G2 in same location and same provider. And I didn't care about the signal lines but the measurement with Speednet.apk. The results made me sad regarding the N3, which was my favorite.
Also I observed that wifi is much less powerful and drops many times, even after all the tricks I've made, when the G2 was constant and no drops at all.
Again, NO TROLLING HERE, but I am very sad to see that N3, otherwise a very nice terminal, is very weak on an elementary thing--signal.
I also made the same tests with different N3 and same thing. I will wait N4 and see if anything will be corrected.
Thanks...

I personally don't have any problem with signal strength in my Note3.

TD2-One of the worse Radio I've seen

Hello World,
Though I was happy with my HD (which is about to be sold) I was waiting the TD2 for long. It's really a great device but seems still to have quite a lot of bugs. One of these is the radio
I know everybody will tell me to wait for a new radio version BUT for those who basically have not a good signal at home or work, I'm not recommending them to buy it untill updates are available..
I've 3 phones with me, one 5 yo Sony Ericsson phone, on Blackberry for work and my TD2 for private use. Where my old Sony Ericsson shows full signal, my Blackberry as well, the Touch Diamond 2 shows a poor 1 bar (!). Sometimes I even have no signal where the others are showing 4 bars.. Well, that's one (if not the) worse phone signal reception I've ever seen.
The same for WiFi... where my HD or my netbook showed full signal, the TD2 shows 1/2 bars, even if the settings are set on "better performance" instead of "better battery"
My ROM version is: 1.39.406.0 (47382) FRE (04/07/09)
My Radio version: 3.43.25.19
Sorry but I had to tell you this as I was expecting this phone since long and don't understand how HTC can ship a new phone with such a bad radio and other bugs... On other side, it's a 5 star device but still have these bugs which are making it a 2 stars..
Thank you for having read ;-)
Well, no software upgrade can give you better reception. But I think you should return your Diamond for check-up, as my experience is that the reception is appr the same as my previous Nokia phone, i.e. reasonably good.
But what I hope they will improve with a radio upgrade is the problems for data connections in 3G/HSDPA mode when the signal is low, in my case this results in a one minute "radio silence" before the phone finally switches to GSM/GPRS mode.
I agree it has very poor radio, similar to how the diamond started, they will improve it over time. Mine is dropping calls in a particular place, this didn't happen with the diamond.
The radio is really bad! I remember that my iPhone had a poor radio reception but after several updates it is much improved.
I hope they'll do the same for Topaz!
I have to agree my TD2 has terrible reception, my diamond wasnt brilliant but the TD2 is very poor. Hope they come out with an update soon.
Are manufacturers obliged to put the same amount of bars up for each signal strength? Can you really compare the number of bars between different manufacturers?
I bought my TD2 last month on a contract with T-mobile. As I have always been an Orange customer in the past I have spent the last four weeks blaming T-mobile for my lake of signal at my workplace, and poor 3g at home.....it never crossed my mind it may be the phone at fault. I love my TD2 but the poor radio performance may be a show stopper
This is very weird. The shop I work, My boss got a blackberry (Bold) AND a PRADA II (from LG), and I got better signal than him. i must tell you tho, it's quite far inside the building, the lowest I have is 2 bars, normally it stays at 4.
But then again, even at 1 bar, I never had problem with calls, lessay it's the same quality as a Triband phone.
The Diamond 2 has a HORRIBLE radio performance, especially 3G connections are very weak, absolutely unacceptable. I'd put the Diamond 2 at the same reception level with the iPhone 3G and the iPhone 3G REALLY sucks when it comes to reception.
Yesterday, I took out my HTC Sedna (6500) out of my closet and tried it again, what a difference. I get a much better signal than with the Diamond 2 (same carrier, same position) and I won't even start comparing the Diamond 2 to the Nokia E90 or even the E75, both have excellent signal reception, especially the E90.
Regarding Blackberry: I use a 8900 Curve 2 for business, this thing really rocks regarding reception. I get a signal (of course no 3G, it has GPRS/EDGE only) almost everywhere, even when the Diamond 2 doesn't get ANY signal at all, it is really impressive.
There are however chances that the signal reception is going to improve with a FW update, it happened in the past with various HTC devices and even the Blackberry Storm I also own, has been improved substantially regarding signal reception quality with one of the latest official firmwares available.
So there is hope but of course it is a huge disappointment that HTC couldn't get it right from the start.

How are you measuring signals being "weak" and the "reception level" - by actual behaviour of the phones in use, or just comparing the bars in the UI?
Rohde & Schwarz CMS RSM. Of course also practical usage too.
temprory solution
the signal problem is very very frustrating, especially when it start to drop phone calls, it became unacceptable.
after few days playing with the TD2, I found that
1. the signal strength appears to be stronger when it stays in GPRS(G) rather then 3G (H),
2. some times when 3G signal is too weak, it will switch too GPRS, it takes about 3~5 seconds to switch, if any call comes in at that time, it will drop.
3. if TD stays in GPRS, the signal is good, even you only 1 bar sometimes, you can still may phone calls without any problem.
so I think it is a good idea to turn off the 3G unless you need to use it, so the phone stays in GPRS, by doing that, you get better signal, and longer bettery life.
to turn off 3G, go
Settings> personal>phone>Band>
select GSM for the network type.
then go ok.
by doing that you will not miss any calls, I think that's the most important thing.
meanwhile, let's wait for a radio upgrade to solve this problem once for all.
Just my 2c worth..
I dont think the radio is any worse, it does the job for me and I havent had any dropouts.
Its an improved phone/pda compared to the TD1 and very happy with it so far. Even without any custom roms, I think the TD2 is very good.
no more of that calibration when you do a hard reset!!!!

Yes, the D2 radio really is pretty bad. I went down on the train to Birmingham yesterday and other people were chatting away quite happily on their phones but my reception was almost zero until I go off the train.
I configure our business phones at work - Nokia E71 is a typical device. They just seem to have better reception. Okay, so a different network but still should be better than it is.
On the subject of radio updates (the use of the name radio I find confusing as I assume it's nothing to do with the FM radio - or does it?), is there an official way of updating from T-Mobile or is it "roll your own" from HTC directly? Have HTC released an official radio update?
Also, do I infer that the radio software is separate to the WM6.1 ROM?
Cheers, Rob.
Hi
Just a few comments really regarding the radio, although I have no advice to magically improve it
First of all, the signal reception on the Topaz 2 is exactly the same as that on my Tytn II, so it performs the same as other HTC phones, now some may argue reception was bad on the Tytn II as well so that doesn't say a lot
When making comparisons with other phones a few things that can help your judgement.
1) Is another phone you are comparing reception with one that is 3G? 3G signals are more affected by walls etc and typically there are much fewer masts than with the 2G and it is quite normal that unless you can see the 3G mast you'll have less than full strength signal reported on 3G, and the 3G signal can drop very quickly even moving a smaller distance away from the mast. If you want to compare the signal with an older phone that is 2G, then on the Topaz you need to set the phone and band settings to make it connect to 2G, and when you do you'll see reception zip up.
2) The signal icons on phones can not be used to make a comparison. One dot of signal on the Topaz is equal to 46% signal strength, so while it looks like a bad signal, it is still almost half and so the scale isn't linear. The other phone you are comparing to may not be reporting signal strength at all, but an error rate or combination of signal strength and error rate. It is possible to get a very low signal but have 100% quality (i.e. no errors) which may be used to skew other indicators higher.
3) The test whether reception is good or bad can only be judged from using the phone and does it work or not, and even then dropped calls may not be due to signal strength but an incompatibility with your mobile operator. This relates to 3G and 2G hand-overs. The phone will try and maintain a 3G connection when transferring data, as this provides a faster speed and it doesn't matter if a low signal causes errors as the data can be requested again. When you make a phone call, the priority shifts to getting an error free connection to ensure the audio doesn't break up, so a low signal introducing errors on 3G will be rejected if there is a nice strong 2G mast to connect to. Your phone then has to negotiate a seamless handover from 3G to 2G while you are talking. In the UK I find this 100% reliable with Vodafone on the Topaz, but calls can drop on O2 when it attempts a switch from 3G to 2G. Newer firmware hopefully ends up fixing these issues in time.
As written by someone in this thread who was on a train when other people with phones remained talking while theirs dropped doesn't prove much, as were they on the same mobile network, and were their phones having to move between 3G and 2G or were they just 2G with much better coverage and no complications relating to switching between the two. Switching the Topaz to 2G only would result in a fairer comparison in that scenario.
Other points, the aerial is at the bottom of the phone not the top, so when you hold the phone you need to hold it higher up so as not to block the signal.

Crap Radio
In response to the previous post I can confirm that I have compared the XDA Orbit 2, Nokia 6230i and Touch Diamond 2 all with a Vodafone SIM. The XDA Orbit 2 is most similar to the TD2 yet the reception on the Orbit was considerably better than that of the TD2. Tests were all completed on the same journey home from work in the same place, at the same time of day with the same weather conditions.
My conclusion, the TD2 Radio is inferior compared to the Orbit 2 and Nokia, but you all knew that already, didn't you. (Appart from the person that posted the previous message!!)
Hi
Nokia 6230i

That is the point I was trying to make, the Nokia 6230i as far as I know is not 3G, so did you compare that with the Topaz switched to 2G to make a like for like comparison? The Nokia also doesn't have to try and accommodate antennas and radios for Wi-Fi, GPS and 3G bands, which can cause all sorts of compromises in small mobile phones.
What were you comparing, just watching the signal strength meter or actually using it for a phone call at the time? The other thing is comparing the phones on different journeys. 3G cells breath which means the coverage varies, it can shrink or increase depending on load.
My conclusion, the TD2 Radio is inferior compared to the Orbit 2 and Nokia, but you all knew that already, didn't you. (Appart from the person that posted the previous message!!)

ehh wtf are you guys moaning about?
like have been said, are you guys comparing with the bars shown in the UI, or with an actual tester?
If your judging just from the bars in the ui and comparing that to other phones.. please go drive a car and crash yourself in a tree
Anyways just FYI: with 1bar 3g im getting a stable (250ms constant ping) 120kb/s connection...
My point being that even tho it looks only to be 1 bar, it works flawlessly. So perhaps our htc phones show the *actuall* reception rather then ** normal reception + 2 bars ** like a lot of manufacturers (maybe secretly?) do.
But i guess htc is better off adjusting the UI bar meter so that it shows 5 bars when its actually 1-3, just to keep dumb people happy....

Yes a very good point. There must be tendency for mobile phone makers to over report the signal to make their phone look better when being compared. My old Motorola phone does state in the manual you need 3 bars or more to make a reliable phone call In other words 2 bars or less are really no servicel at all, and from memory it would jump from 3 bars to no signal more often than not skipping 2 and 1 bar of signal strength.

Hi guys, I'm about to buy the TD2 and reading your post I got a little worried about the radio signal of this device!
I have a question for people that complained about it:
Did you complain for the quality of the calling connection?
I mean did you lose signal meanwhile you were talking or have you got bad conversation due to the low signal?

No working GPS? No problem. No froyo? No problem. Bad reception? Problem

First off I'd like to say I'm thankful for everything the devs here do. I've tried the 3g fix and it didn't do anything, so now I'm just curious if there is anything else out there that fixes it.
I'm on the newest DL09 and the problem is still there. Bad reception. I'm serious when I say I get full 3g bars maybe 1% of the time, and I'm dead center in a verizon 3g area. I've never seen a signal jump around as much as on the fascinate. It will switch between 3g and 1x constantly throughout the day, and when it's on 3g it looks like the bars are dancing all day long because they just jump around.
My original Droid will have a steady 5 bars pretty much all day. Fascinate...not even close. It's getting ridiculous actually. I can download updates for apps on my droid no problem, but I actually wait til I get home on my wifi to download updates on my fascinate. I constantly get "stuck" loading a page on the net because of the ridiculous reception.
Now my question is...is there any fix out there that actually works that I might have skipped over? Good reception is a HUGE thing, especially when I'm dead center in a 3g area, and the fascinate doesn't have it. I'm thinking about selling it in the next few days because it's absolutely crazy.
People complain all day long about the GPS and no froyo...and I'm actually confused as to why many do not complain about the reception. That's the biggest issue with the phone IMO.
Thanks for any help.
Have you actually tried contacting Verizon about it? It sounds like you've got an antenna issue, which should be pretty easily addressed with a phone swap.

My friends has the same issue, and I've seen people complain about it before. So I think it's a fairly common issue.

I'm assuming you tried the reprogramming codes?
http://www.ehow.com/how_4532332_reprogram-verizon-phone.html
probably the 1st thing you tried, but just checking. I know for me, i went from being in the -102 range (1 bar) to -89 range (2 to 3) at work. Also at home i went from -92 to -51 (MAX)
You did option 2 correct?
Just did option 2 and it seems to have done nothing. Going back and forth between -96 and -101
If you dont see people compalining about reception, its largely due to the fact that the phone doesnt really suffer from reception issues. If I were you, I'd call verizon and make a formal complaint about the hardware restricting your usage, I'm sure they will work with you.
I'm a sales rep at a Verizon corporate store, 4 of my co-workers have Fascinates and we ALL experience a MAJOR difference in signal quality compared to co-workers with Droid X's and Droid 2's...
There's a five page thread on droidforums (fascinate section) about every single person in that thread having reception issues on the fascinate. And if you do a "fascinate reception issue" search on google, there are threads everywhere about that.
I just have a feeling everyone is focused on froyo and GPS so that's why reception isn't brought up much. I highly doubt, with as many people that have this problem, that it's just a problem on some of the galaxy s phones.
agreed bro i lose signal from my bars are really sporadic

Yeah it's very frustrating.
What's even more frustrating is even when I get 4 full bars I only get -89 on the mobile signal widget..that's far from max reception.
I've never had reception problems per se but I have full bars and 73 dbm. Also for some reason my 3g download rate is nerfed. Earlier today on speed test got 63 kbps and 462 ping dunno why. Mostly hovers in the 300kbps range

I've had two phones now, and they both have very poor signal strength. Comparing my Fascinate to a friends Droid, sitting just a few inches apart, he had a dbm in the mid to high -70's, while mine was in the high -90's.
If you're in a solid coverage area, it gets fine reception and you're not likely to see the problem, but as you travel into a lower signal area, the Fascinate trails off very, very sharply. Even though I live in an area with supposedly blanket coverage, my house is towards the bottom of a small hill and I typically get zero or 1 bars on the display, every once in a while 2, but it'll drop back to 1 or 0 as soon as I pick the phone it.
The Fascinate does have a very week antennae design.
I rarely see 3 or 4 bars...come to think of it, I don't think i've ever seen 3 or 4 bars. This is when I'm in an area which should definitely have excellent coverage.
OP: do you have actual symptoms of poor signal like slow down/up load or dropped calls?
My speed tests when i have 1bar 3G are about 800Mbits up and 500Mbits down. Never dropped a call (rarely make calls, though). I have read that some folks suspect that the Fascinate has reporting issues? I don't know...but since I'm not seeing horrible speeds I've tried ignoring the fact that its always reporting 1-2 bars.
Kind of similar to the TWoS thing. I chased this one for a little bit too before dismissing it as a reporting issue (for now).
I originally was upset about the reception but came to realize that the office building I work in is built like a bunker. Other then when I am in the center of the building I get good reception, at my desk near a window I get 1-3 bars. However anytime other then when I am in this building I almost always have full bars.
However I have noticed that when I am in my office what ever bars I get my friends droid gets one more. But when it comes down to that it isn't Verizon...again the problem is with Samsung.
Hey guys,
what if I did option 1 instead of option 2 in *228 reprogramming?
On another note, my 3g indicator constantly disappears in verizon hotspot areas, it is really quite the annoyance.
Are you on a stock kernel?

The reception for my Fascinate isn't spectacular. I don't know how it ranks among smart phones, but there is a definite difference between it and my chocolate 8550. In known holes in vzw's coverage I occasionally lose signal, but I don't use it as a phone enough to drop many calls.
However, I spend the majority of my time in strong signal environs, so it doesn't really come up as an issue for me, and I just accept it. It will be a decision factor for my next phone though.
Maybe others have a similar situation: worse yes, but liveable.
Swyped w/ XDA App. When in doubt, mumble.
I have noticed the signal over the past 24 hours has been jumping all over the place like Verizon may be running tests or something. The drop being very consistent intervals of no bars but still 3g.

Weak cell/radio signal - anyone else too?

Put simply, the Note 4 has the worst signal strength of any phone ive ever had. I use 3 UK. Signal is weak inside house especially downstairs. Recently i have had the blackberry passport which was amazing signal wise. I currently have an iphone 6 plus too. The 6 Plus can make calls downstairs just about. The Note 4 has no reception.
In fact i have noticed the signal is weaker wherever i am...
Anybody else notice this. .
I really like the Note 4 but the weak radio is going to give me a problem. Maybe samsung can improve the radio with a firmware?

Note 4 N910C, Mexico.
I'm having the same issues, WiFi signal is excellent, no problems whatsoever, but the cellular signal is really low.
Take a look at the screenshot, I'm in the city downtown, where usually I have really good signal using another phone (Xperia Z1)

I agree n910u australia very poor signal
same here
It depends on the phone signal gaining hardware.i too have a sony which has excellent signal strength always.

This is not good. Maybe we should not have asked Samsung to build a phone using metal! I also have the Gear S which is great. But I need the Note 4 to use the Gear S. I also need a phone to make phone calls so this seems like a design issue. Sad.
Here, in downtown Amsterdam I have bad 4G/LTE signal inside my apartment too, but it's even worse with my Galaxy S5. On the other hand 3G is full bars. In the elevator of my apartment building the S5 loses his signal completely (no network) while the Note 4 survives with a very weak signal. But overall both the Note 4 and Galaxy S5 suck at cell reception. You will have to learn to live with it.
Check if you have the latest firmware or baseband installed?
if not, try to update it.
Unlocked N910C Useless as a phone
My reception ANYWHERE is crap. I'm using AT&T's network and I have a Galaxy Tab S unlocked that has a phone and that has 3 or 4 bars to the GSNote 4 having maybe 1. I'm wondering if this happened because I rooted with CF Autoroot, as it seemed to appear after that, but I have no idea. I unrooted and flashed the latest firmware (NK5) and I still has the same crappy phone reception problem.
I too have ****ty reception.. wifi is good. but cell reception is bad..
Same here, N910C
Baseband: ANJ4
Same here , like my old phone m8. It must be metal case problem?
I have the same problem with Note 4 as with 3.
One of the reasons I changed to was the problem with calls was shut down in poor reception areas.
The problem is not there at all with my daughters iphone.
We can drive in to bad areas and mine is cut off and she's not.

It is not just the qualacam. I have the n910C and it too has a very bad signal. I have tried every baseband to date and they have no effect. It is only the 3G and LTE that are bad. GSM is OK.
I sometime cannot even get the 3G while my iPhone has a full signal. I too noticed it after rooting. I just don't remember it being this bad when I first bought it.

The frame metal has nothing to do with reception (see the placement of the main antenna relative to the body on page 8). I cannot comment on other models but I've got the Canadian N910W8 and my signal is EXACTLY the same as my other 2 Galaxy S4's.
In your cases, I believe it's rather a software issue/mismatch (CSC/modem/RILJ, etc), especially If you bought it from a different country/region, you should probably start with the phone's CSC, matching it against your residential location...
Also, try choosing a non LTE network connections under More Networks > Mobile Networks > Network Mode. If the signal improves considerably, you're living in a poor LTE area. As of right now, since VoLTE is not yet widely supported, only your download speeds would be affected by leaving your phone connected to a non LTE network.
Same problem with my brother's note 4 bought from UAE. Its an exynos version. Turning LTE off does not improve the signal strength. On the other hand my note 1 (exynos) and lumia 1020 have excellent reception in the same room.

OK, you bought the phone from UAE, but where are you located/using the phone? If you're using it in a region/location other than UAE, then you should probably consider installing the modem for the region you're currently living in, and also changing the CSC.
Mine is from Slovenia and using in Greece. Signal is crap. I have nexus 7 2013 and has far superior coverage with the same network. So no network different there.

RAZR M Radio/Wifi files

I have an Australian RAZR M Retail XT905. I upgraded it to KitKat from JellyBean and WiFi reception diminished noticeably. I cannot get a signal where I got three bars before easily.
I read on xda: http://forum.xda-developers.com/showthread.php?t=1711603 that you can change the values of antenna power (RSSI).
I was not able to find the files mentioned in the thread. Can anyone point me in the right direction.
I'm guessing it doesn't exist in Moto ROMs. My XT907 doesn't have that file either. HTC phones obviously have different ROMs.
Ironically though I was just going to ask in the Ask any question thread what is the best known baseband version, and if I'm unlocked can I flash it regardless of which ROM I'm currently running. The only one specifically listed in the Index thread was 98.18.78 (which I'd surmise came with that JB ROM). I too would swear I had better signal before (but I also know from older Samsung Galaxy S phones that the number of bars displayed don't necessarily correlate to the actual signal strength between different builds).

I also know that bars and signal levels do not co-relate. Mobile reception is same as before. But my mobile carrier's signals are also very strong. They are at -51 dBm at my house and around town. And you get four bars at -70 dBm. That has remained same (i think it might have improved a bit).
On the other hand Wi-Fi quality has suffered. I used to get 3-4 bars in my bathroom, now I can hardly get a signal. Name of the network just appears and disappears under Wi-Fi settings. Now even in the same room as the router i can see fluctuation between 3 and 4 bars.
I am on bedrest so I have not tinkered much with the phone. I will later soft reset it. The problem is that the KK and JB modems donot work interchangeably. I guess they require their respective bootloaders.
There should be some setting, I guess they have limited the power due to some regulation. You can also see regulation stuff in "About" menu. It was not present in JB.

Wow, I wonder if I've ever hit that high of signal even standing next to a new tower. I'll have to check next time I'm there.
Just yesterday I was surprised by the wifi signal since it was showing just a fair signal when I was in the same room as the router (basement) yet it's the same on the second floor.
I had wondered if the radios could be swapped. I've considered going back to JB since I got great battery life then. Though I do think poor signal was a contributor to the bad life on KK (seemed like that is when the phone would most often really heat up), so far this new Razr M I've now unlocked has not been as bad as my old locked one was. I'll keep it for a few weeks so I have a decent baseline and then may flash back to JB for a while to compare.

I wonder if your high signal is because you're on Edge rather than 4G.
I did check standing about 100m from the tower and the best it recorded was -74dBm for 4G and -53dBm for 1X.

Signal S8 Exynos

Hi all,
i want to know how good is signal/modem (strength, stability and all other stuffs) of the Exynos version. I need this feedback cause i am now on a note 3 N9005 snapdragon and from the first day i take this phone, modem was very very bad, slow on change 2g/3g/4g, weak singal strength, randomly (very often) the signal drops to 0, also when is good (like 3/4 bars on 4); this make me mad and i need a phone that is perfect under signal/moden/call quality.
Thanks.

Same case with Note 4 N910c.....very bad modem...very slow switching from 4g to 3 or 2g...sometimes restarts when receiving calls...so...I'm hesitating to purchase the new s8 especially some people complain about random restarts which I predict them as result of bad modem....by the way, I had Huawei mate 8 but never experienced any problems with network or signal strength ...the problem with mate 8 was the system which I found very bad..
I am still with Note 4 but I use only 2g to avoid modem problems till I see the new Oneplus 5..
Good Luck with your new phone..
I had an S6 edge and now an S8+, had no issues with the modem, found it consistently better than my partners old iPhone 6.
No issue with the signal in the States...
