LTE poor signal?

Hallo, Vodafone Italy still not offers LTE coverage in my city, but there are some cells that already have it enabled.
I noticed that when I'm under 4G, my signal never got past 2 notches.
So I ask to who is covered: is this right or do I need RMA?
Thanks...

I'm supposedly in a very strong LTE area and I usually see two bars. Occasionally there will be three bars holding steady but rarely do I expect to see four (out of five). My speeds rarely change from 16-18 up and down (downloads always faster. Zero packet loss on T-Mobile. My Nexus 4, on the other hand gets low speeds and between 2-4% packet loss.

Are you talking about the signal bars in notification area as "notches"? Trying to see if thats what you said. If so, the signal bars do not dictate the LTE strength, just cellular call strength. The LTE download could still be great even in no signal bar areas as well, signal does not influence the data strength nor does data strength dictate the signal quality via the bars. Since the phone has to turn off LTE to "switch" to 3G in order to make calls, the "switch" may have something to do with the bars.

Thanks, that's exactly what I wanted to know! And, yes, Italians call signal bar "notches"...

LTE signal indicator issues

I've realised that the signal strength in Phone Status (in dBm) does not seem to work correctly when on LTE. Very often, it'll show that my signal is -113 dBm, which is an extremely weak signal, while showing 2 or 3 signal bars. Something is obviously wrong as 3 out of 4 bars should NEVER be as weak a signal as -113 dBm. Is anyone else experiencing this?

LTE dBm are calculated differently. 113 is good around 140 is bad.

I've read that signal drops off at -120, so -113 is pretty close to the edge, but either way, that signal indicator is wrong. If I go into the service menu (*#0011#) the RSRP (dBm) it shows fluctuates from -91 to -98, which seems to be the more appropriate dBm for 3 bars of signal. The dBm in my phone status still stays static at -113 (it doesn't fluctuate at all)

As per your request in the other topic here are my findings.
I live in Amsterdam and I work in the harbour area (a lot of open spaces). I work next to a 4 x 3 meter window. With every device I've owned I would get full reception. Though under settings > device > status it would always say -113. My reception bar is always near empty.
When I go outside, even in the middle of a park in the middle of the city with nobody around, I will still get the same result. In my apartmentbuilding, on the 7th floor outside on my balcony, same result.
I'm currently in the office so I thought I'd send a screenshot of what the *#0011# screen looks like.
(Apologies for the big image)
In my parking garage I would even get reception with my OnePlus One, which isn't really great when it comes to reception. It would be only a sliver, but at least I would get something. The S6 doesn't get anything. When I leave the bigger urban area I'm immediately knocked off 4G and 3G and I'm pretty much left to calling and texting. The Netherlands isn't really like the outback of Australia, I had expected better
I can live with not having reception in my parking garage, but I'm more concerned with the fact that I've never seen more reception than you can see in that screenshot and that I have close to no reception when I go out of town. I'm using T-Mobile which I know only uses the higher frequencies. In the Netherlands they use 900 MHz, 1800, 2600 MHz. I don't know if that comes into play much. I had a bit better reception when I was still at Vodafone, but that was a few years back. With a top of the line device like the S6 I had expected better. Much better.
Maybe I should have the device swapped?

I see that your RSRP is the same as what it states in the phone status menu. Does this number ever change? For me, I (mostly) always see -113 (such as right now in my office) but my RSRP actually fluctuates. Screenshot of my RSRP attached.

In my phone status window I've never seen it change. In the RSRP it does vary a little bit, from -115 to -110.
I actually just got it working properly for the first time. I went to the rooftop of my office, as far away from anything that could interfere and I got -77. Bars actually went up too which I haven't seen before. So I guess the device really does just have poor reception. Strange that not more people are reporting on this though.
Edit. These guys are also reporting on low signal stuff: http://www.theregister.co.uk/2015/04/08/samsung_galaxy_s6/

Unfortunately, I've noticed the same thing, though not nearly as bad as what The Register is experiencing. For me, it is only slightly worse than my G3.

The review sounds pretty accurate to me, but others are reporting their device has connectivity as good as HTC's M9. Luckily I've got an M9 lying around, so I'll put my sim in that and see if it too gives me poor reception.
---------- Post added at 02:49 PM ---------- Previous post was at 02:36 PM ----------
Haha, I guess I have to blame T-Mobile and not Samsung. The M9 I have gets -112 dBm at the same location where the S6 has -113 dBm. Seems the problem is with the network and not with the device. Not sure yet if that's good news or not

Well, it's good that you know it's not your S6! I was actually walking along a street where I got horrible reception with the G3 (after I posted the last comment) and realised I was actually holding onto a signal when the G3 would lose signal completely. Guess it's not as bad as I thought!

We're just too critical Glad we got it solved, haha. Back to fully enjoying the device!

I have this issue also.
I had a nexus 5 before on EE and pretty much always had 3-4 bars if not full signal. On the GS6 still with EE i rarely see it go above 1 bar.
I am still within my 14 day return time but i am stuck now with what to do. Do i risk waiting to see if this is fixed with a software update or return it. If i wait and its not fixed them im stuck with a phone that gets very little signal. If i return it i have no idea what else i would get as i love this phone. I have also tried another GS6 in store but same issue so makes me wonder is this a software or hardware issue. Seems several people on varying networks have this issue.

I have the same experience. -113 dBm at home inside our house.
1 max 2 bars on the signal indicator. Lots of places where I had 4-5 bars on my One M8 I now have these -113 dBm on S6 4G, or only 3G connection (-79 dBm - 4 bars, the max on S6). Sitting here with my SIM card placed in my M8 I get -98 dBm 39 asu inside our house. Thats 4 out of 5 bars on the HTC indicator. It's the same with other 4G handsets we have in the house. I have a cheap company Nokia 4G phone that also have 4 bars inside the house. I've had a Z3 compact that also had great reception on 4G. I think I have data enough to conclude:
Conclusion: S6 have bad LTE/4G reception. Very very sorry about this. This is a real stepdown from what I otherwise think of the S6 handset. Other than that, I don't know wether this can be made better by software, but I doubt it..
EDIT: Just tried by wifes Samsung A5, which sees -97 dBm on my SIM card.

Different carrier roms seem to deal with the signal differently, but essentially it's a cosmetic issue. I'm using the Three UK (H3G) rom and my signal bars work fine but my dBm signal level in settings is always stuck at -113dBm.
I took these 2 screenshots at the same time standing in a great 4G signal area:
http://i.imgur.com/n6eUmaS.png
http://i.imgur.com/v5KsmgH.png
As you can see, the settings shows -113dBm but the service menu (*#0011# in dialer) shows -84dBm.

Maybe this thread is really about that - the signal interpretation internally. But nevertheless my S6 handset is 'downscaling' to 3G all the time (and staying there), hente twice the roundtrip and less bandwidth for me.

It sounds like you have a different issue. Have you tried checking what your signal is in the service menu using *#0011#?

I'm getting an error dialing the service menu (OSSD code) stating N/A.

Here in Italy very bad signal with TIM also with 3g. Where my Iphone and Note 4 get full signal only 2 bars on my GS6. What the hell Samsung always release buggy phone!!!

I forgot to mention that I was running the Lite version of the stock rom found here on XDA. The service code don't work on that rom, which made me downgrade to my backup of the stock rom.
I'm getting RSRP:-98 RSRQ:-6 RSSI:-71

Bad network signal / reception?

I was wondering how everyones experience with network signal is on their S6.
I upgraded from an S4 i9505 to the S6 SM-G920F and I notice that the signal to my network is about -5dBm worse on average. It means the phone isn't as good at keeping signal in a low signal area, and it drops from 4G to 3G much more often that the S4 in the same place.
Maybe my antenna is bad or does anyone else experience this?
Also, don't use the signal bars as a judge of your signal. Samsung has changed them, for example they now show 2 bars 4G when my S4 shows 1 bar. Both phones could have -105dBm and the S6 will show 2 bars but S4 1 bar. It makes it look as if the S6 signal is the same or better when in fact the true signal is worse on the S6.
If you want to see your true dBm signal on the S6, go to the dialer and type *#0011# and choose STACK 1. Your signal is the RSRP.
Screenshots attached of S4 and S6, you can see S6 shows 2 bars with -109dBm and S4 shows 1 bar with -106dBm. S4 has a better signal, so don't believe the bars.

Well, i have a couple of flagship cell phone, including 2 motorolas ( Turbo and X 2nd gen) , i thing it might have differences from region to region , but from my experience , Samsung and LG was the ones with bad reception from past experience, S3 , S4 and S5 they were always with a bar or two lower than other phones, and when motorola has only one bar , sammy was with no signal at all ,long time already .
Well, motorola are the best in signal strength for me, follow by HTC. This time sammy has improved, i guess it's the in-house chips or something. Still no Motorola tough .
I guess we notice those things because we live or work in a region that has weak signal so a little bit more or less makes huge difference.
Here is my screen shot right now. The signal bar seems to be accurate with the signal db.

Thanks for the screenshot Galinha1. That's interesting that you find Samsung has improved this time around. I notice that your screenshot has "Ant RSRP Diff" at a minus number (-26) but I've never seen mine in a minus, you can see mine is at 14. I don't know what Ant RSRP Diff means though, any ideas?
If you find that the S6 signal is better than the S4, maybe I have a faulty device?

I have the exactly same experience. The S6 is more agressive drops to 3G. I'm coming from an HTC One M which in my everyday, according to OpenSignal, has 70-80% 4G connection 24/7, the rest 3G.
My S6 has around 30% 4G, 40% 3G and 30% Edge . Because of the great camera in the S6 I have decided to stick with it for now. Sadly. The great 4G signal in my area actually made me stay on 4G all day on the M8 and disregard wifi usage. On the S6 I've falled back to wifi which on my connection is a lot worse than 4G.
I'm really hoping for this issue to be in the Modem/radio firmware and not in the psycially device.

Well, i don't know for sure if it's better than S5, it's been around 7 to 8 months i last used my S5 . But i remember that it was a really bad device for signal and call quality. Looks like it's better or is the placebo effect from a shiny new toy . About yours been faulty , well, before last week i would say no for sure, i would assume a firmware or modem software issue, not hardware, but i bought my S6e 2 weeks ago, and i had a lot of drop calls, random reboots , freezes ,and people complaining that they call me and the phone rings once or twice and hung up , and in my end i never saw that attempt of calling, so i tried a new firmware, updated, downgraded it.. still having issues. So i went to my carrier and they didn't even let me finish my complains and handed me a new device. I went back home , thinking that couldn't be hardware issue and this new one would have the same problems. But now it works as it supposed to do . So i guess they might have a lot of faulty devices and software issues for those initial batches . Although i still have some drop calls, and 3g or 4g drops , is not that noticeable like it was before.
I have no idead what ANt RSRP Diff means.
I hope you solve your problem, anything i can help you let me know.

better than my old nexus 6 and m7. plus it holds onto lte much longer

I also have issues with cell reception. I'm on att, and although in areas where signal is strong there are no issues, I have serious issues maintaining a cellular connection when the signal is mediocre. I'm at my wits end with this. The phone seems to run fine, no issues besides the fact that I don't get signal in many areas that my old Nokia lumina 930 had no issue getting reception. Also, ive compared with a few friends iphone 6's and they have signal while my s6 will have nothing. I will be bringing the phone in tomorrow, but if anyone has any other suggestions to fix this besides factory reset, which I've already done, I'd appreciate the help.

I also had problems with cell reception. (no signal, drop calls)
As suggested on several forums I changed the network mode in settings to WCDMA/GSM and this seems to solve the reception problems. This way I am not be able to use 4G but at least I can make calls now XD

Well looks like it's many more of us than I thought... I am on EE and reception is a joke ( joke anyway on EE) but with S6 reception is much weaker than on any previous phones I've had. What firmware r u running

I am on stock 5.1.1 G925FXXU2BOFJ
I believe the version is the same for the G920F

Just came back to Verizon after being with T-Mobile for a year. Signal is pretty much the same at the house as I has always been.

Around town it is normally pretty good. At work, it is much better than T-Mobile ever was.

S4 has better 4G signal then S6
This seems to be a problem world wide. Looks like Galaxy S6 is having issues with 4G. I compared it with my old S4 and it's way worse.
Here are the results.
S4- 4G inside the house signal: -109dBm 31asu
S4 - 4G outside the house signal: -102dBm 35asu
S6 - 4G inside the house signal: NO SIGNAL
S6 - 4G outside the house signal: -113dBm 0asu
On my S4 I'm getting a better signal inside the house than what I get on the S6 outside the house.
Does anyone know the reason for this and is there a fix?

4G is calculated differently than a 3G signal
4G: (113 is good, 140 is bad)

[Q] Signal Strength

What kind of signal strength are others getting compared to other phones they have owned. When I am in an area that has excellent LTE coverage (as consistently shown on multiple other phones I have owned) I am only getting about one half to 3/4 of the signal I had been getting. I have yet to get a full strength LTE reading on the signal strength indicator. I am also having problems with the signal dropping completely (no service) and then coming back at 3/4 strength? Very flaky.....

My AT&T signal was always terrible. Almost always 1 bar but sometimes two. I preordered a H2O Wireless SIM about a week before I got the Idol 3. My AT&T plan expired the day after I got the phone so I just popped in the new H2O sim into the idol 3. With the H2O sim I get really good signal, sometimes full; bars! The weird part is that H2O uses AT&T towers so I can't explain why I am getting better signal except that it could be the phone. Unfortunately I was unable to compare the same sim card in both phones. Overall signal strength is better for me.

i got the same problem i had a moto G lte had all of the bars then i put in my sim card and now i dont get much signal even at work with the moto i had all of the bars and this one i get like half then dissapears goes back to half then of a sudden all of the bars show im running cricket and as same as you we run on ATT towers

I had to set mine to wcdma/gsm on T-Mobile to get good coverage. It wouldn't pull signal unless it was 5 bars LTE.

Tmobile in SF. Brand new phone less than a week in use, also terrible signal. LTE Discovery shows I'm on band 4. Funny enough I still get calls and txt messages when displays shows not signal at all. This is one thing I hate in reviews, they all mention how fast and great display and audio, but none of them mention call reception. IT'S A FREAKING PHONE!!!

My signal sucks regardless of this being a Band 12 capable phone. I know you should never go by the signal bars, but rather the dBm's/asu, but my signal strength fluctuates constantly and doesn't even show signal at all until a few seconds later as if it "reconnected" to the network and jumps 2 bars. This phone needs a major modem update. I don't think I've ever seen my signal bar icon fully lit even when I'm outside. Maybe I just need a new SIM card.

My network is fine. AT&T/AIRVOICE. SLC, Utah.

I compare my Idol 3 signal to varying Androids i know that are on Tmob, it seems to be par for the course. Often it is half a bar better. It is certainly better than the OPO i sent back.

Very poor XLTE speeds & weak LTE altogether

Can somebody please help me figure out why I am getting poor XLTE speeds? In a couple different legit VZW stores I have played with the S6 and also G4 on display and speed tests there are pulling 75mbps down and even higher than that on a few tests yet my S6 doesn't seem to get any speed tests higher than the speeds I was seeing on my Galaxy S3......30-35mbps down at best. I also have noticed my dBm isn't nearly as strong as my S3 pretty much at all times. Driving right by a known VZW tower this morning I was getting -85 to -90 dBm LTE signal when with my S3 I would be getting -55 to -65 dBm LTE signal.
I am currently not rooted, running Build and Baseband AOC3. Will rooting make a difference? What about AOE2, is that build and/or modem significantly better? Also I currently do NOT have Advanced Calling enabled, will enabling that give me better speeds?
I apparently am missing something. This phone operates very quick imo but the antenna is a joke it seems., unless I am missing something incredibly obvious?
Any help on improving my speeds would be much appreciated. Thank you!

I hear you. I have been very disappointed in my S6 connection speed also. I am in 3g in a lot of places my old HTC DNA never was. I am also rooted running clean rom. So rooting will not help the weak signal.

It's ticking me off. Such a great fast device otherwise but the antenna blows and evidently there's no fix for it.

My understanding is that Verizon stores have a mini tower in their stores to shore what the network is capable of (or to get you to use their service) whichever way you look at it. However IRL the network has hundreds or thousands of other devices connected to each tower which slows down speeds dramatically. I live in a bigger city but I'm driving all day and when I'm home I have 4-5 bars but dismal speeds where if I'm in a smaller city I can have 2-3 bars and have great speeds.
