That's not bad. maybe move to a window mate. I got only 2 bars on mine as well. More than likely just ****ty signal. I get 3 if I'm outside in a tree or something. Look up a app called lte Discovery and you can get some ideas of strength from it

Note 3 Rubbish Signal... wrong modem? help needed

Hi, I bought my note 3 in UAE and I am using it in the UK. I am on Vodafone. I always get rubbish signal in my house. It is on "emergency calls only" nearly all the time. Also the LTE/4G has NEVER worked since I got it on launch (Sep). Whenever I turn the 4G on the H+ sign never comes up. Some people may argue that Vodafone is a rubbish network. I agree too but I think I may need to flash a different modem? My model is a SM-9005. Do I need to flash a different modem to get the 4G to work? Thanks

You can actually try a different ROM or maybe a custom ROM? At the same time, reception might just be poor in your house. So you might need to make do with regular 3G or EDGE. I no for a fact that in my friend's house i ALWAYS have to switch to 2G because 3G reception is never available, I have SM-N900 tho.

what if i flash a different rom/modem?
I just checked and vodafone operates 4G/LTE at 800MHz. On the samsung uae website it says that the note 3 supports 800MHz 4G/LTE
ROM's won't make a difference as it's the hardware on the device itself.
I also noticed the note 3 doesnt have a superb signal reception... For example in my house my moms s3 and dads s4 have full bars where i on my note have one bar less than they do. Little dissapointed

Check phone status in settings and compare it with the S3 and S4 - you'll see it's just the bar's that show different the dBm's are what counts. You'll see it'll be identical to the S3/4

The device itself has the bands. But you cannot access them by changing the modem. The N9005 supports many many bands but different MPN Codes on each device limit it to specific countries.
It's all a legal thing. Radio frequencies are controlled, unless the UAE version supports the exact same frequency that your UK carrier runs on it won't work. Upgrade to kitkat and test it.

[Q] Galaxy Note 3 modem version - improves signal strength?

Hi,
I have had the note 3 since release here in the UK. I have a unlocked version from car phone warehouse on the three network. However I have poor signal at my desk at work if I hold my phone in the right spot I have H+, but the right 'spot' moves around unfortunately. According to their coverage map I should have LTE signal indoors and out. I do have 4g signal if I leave the building. (I am in the center of London)
So as it appears my signal is close but not quite good enough, I was wondering if there is a good modem firmware out there that people have found helps? I am running the latest software updates (the last 1 I installed was the KitKat upgrade).
Thanks in advance
I am on Giffgaff, they use O2. Currently using the NC2 Modem with no issues and great data speed.

Short off topic, but i dont want to create a new thread: You can only upgrade modem in odin of you have "official status", is that correct? How about a TWRP backup of the modem partition? If s.o passes me TWRP backup of the modem partition, can i upgrade/downgrade modems?

Thanks for the info
my current baseband version is N9005XXUENB1
so the NC2 is slightly newer isn't it? am I right in my understanding that the version number is the last 3 characters of the baseband version?
Is there a good resource where I can get the latest modem version from?

My status is not official. I powered off the phone, waited a few seconds and did the button combo for download mode, and it flashed fine
I have a backup of my current rom/modem in TWRP, i havent had to restore it yet so i couldnt tell you.

Yes it is slightly newer by about a month. If you go over to the alexndr Rom thread in the android development section, in the first post he has just the odin package, its about 50mb.

Katkat modems don't seem to be any different btw, seems they've just rebundled and named the original one - Carrier modem *may* (I say may because I seen no difference) be tweaked slightly different but ultimately it's just a placeholder for APN settings really.
Indoors, always tricky.
It could be related to the frequency band your provider is using. The 800Mhz band penetrates solid concrete with ease, but the higher bands can't.
Any metal in the walls? Killer for any digital signal.
Does anyone else experience the same issues with other phones on the same provider in the same spot?
3G is always weaker than 2G, and 4G is even less powerful than 3G. (Because of the higher required frequency). Have you tried enforcing GSM mode? It'll kill your data speed, but at least you're more likely to get a signal.
Thanks for the help guys.
Yes other people have signal issues too, so I am just looking to get every ounce of signal strength I can.
I had a chat with my network last week and apparently before the end of the month they are rolling out a new spectrum but the support guy didn't know which frequency it was. he was confident it would fix my signal issues. (how true this is or not guess I will see!)
I have tried restricting to gsm and it is still unstable unfortunately
According to the coverage map, 4g signal in my post code is very strong, DC-HSPA i'm on the edge of a strong section. but right on the edge so I can understand dodgy signal. Ive just got my fingers crossed over the next few weeks
Silly suggestion, but... Have you tried opening a window? it could add just enough strength for the signal to stabilize.

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Samsung Galaxy S10's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.
Not as good as my Moro Z Play for picking up signal in. At work most of the times I get 1 or if I'm lucky 2 bars.
The S10 (Exynos) cannot hold on to a 4G data, while the Moto Z can
Tried two different networks (O2 and Vodafone), same result
Even iPhones (seen lots of people with 7/7+) have no trouble
Keep interrupting phone calls whenever the signal is not good (worse than an S7)
4G will randomly stop working even does it displays 4G+ wit full bars.
I'd have to restart te phone to solve the problem
4G/LTE on S10+ Exynos working better than Note9 Exynos on US T-mobile. No issues so far.
Working great. Good speed results on AT&T 5GE

Did you have to change the CSC or anything? I'm getting worse signal than with my exynos s7.

No, it worked fine out of the box. TPA CSC is what I have.
Make sure to compare the actual signal value RSSI as signal bars can be misleading

Thanks for the reply. Yeah I'm at -120ish so basically no service whereas my s7 was closer to -90. I'm also using the TPA CSC and assumed that was the problem but maybe not. I'm tempted to flash an unlocked US firmware.

That's a huge difference. There is no US unlocked firmware for Exynos though. You maybe able to flash unlocked UK firmware for Exynos

Hmm I'd say only flash firmware from reputed sites like Samfirmware. That firmware you mention is likely mislabeled or incorrectly categorized.
S10E at least has a working fingerprint reader lol

True. Do you think it'd make a difference to flash T-Mobile firmware from another country ( like German, Chile, etc.) Or one that's unbranded/unknown CSC?

I think BTU UK unlocked should be a good start. Factory reset may also help. I'd also try different SIM card to see if that bad signal issue is limited to the SIM or T-mobile
You should also check if you live in area that has band 71 primary coverage as that is not supported on this model

I haven't tried a factory reset but T-Mobile did give me a new sim to see if that'd fix it. I checked me local coverage and I have all the bands for my area so I'll try a factory reset and maybe different firmware. BTU didn't show up on sammobile btw, but I may try the "unknown" one.
I think Exynos has multi CSC firmware and the active CSC gets decided on which SIM you put in after factory reset. But since you're on T-MOBILE USA it'll default to original CSC

Same here with Snapdragon S10 in Hong Kong.
I have s10e and after the security update of 1st April I am facing issue with the network. It's like when the network setting are on lte/3g/2g , then only 4g is working with no network for calling, it shows not registered on network. If i change it to 3g/2g then there is no 4g signal, but calling is possible. It was not there before the update.
I am using Airtel (in India)
for best signal, you need Mi9 (the flagship of the year), have both so yeah, Samsung shows very few bars in the same locations.

4G or LTE on s10+

Well, I searched for this thread but couldnt find it, if theres a original post, im sorry for making a new one, but I had S9 and always on the top right corner was LTE icon for my cellular network. I bought S10+ and with the same SIM and same cellular, im getting 4G and 4G+ only, no more LTE. I know LTE is basically the same as 4G, but still it looks nicer to me when it says LTE. Maybe its up to the firmware, I dont know. Some advices?

When I was on the U firmware of Verizon I used to see 4G/4G+. I moved to U1 firmware and now I get LTE/LTE+. Possibly it is indeed uptown the firmware used.

I had the same issue after csc change tht aftr I used *#272*imei# =>>turned my s10+ INS/INS, INS/INS into BTU/BTU/, BTU/INS. It always was LTE in my netwrk tht suddenly became 4G+. I dint worry at 1st but ws shocked whn the phone lost call recording feature, caller ID and spam protection, offers showd in pound in Samsung members app instead of INR. I could never fix ths issue bcz tht csc changing code was unidirectional, it dint work after the phone became a BTU phone. None of the old methods to change csc worked. I got the phone replaced by Samsung aftr few weeks of struggle nd thn all became normal.
Probably have to root your F model phone to get LTE to display. You better off asking this question in the other forum section for a more accurate answer.

Mine has 4G and LTE. I win!
But yes, the icons are dependent on csc.. each carrier can tweak the icons to their liking, if u look through the csc code you will see what i mean.
i dunno if any apps exist (they used to) that let u change the icons but i would just go that route if i were you.
