3G AT&T Calls on Fuze: Not Reliable!

I wanted to start this thread to discuss making and receiving phone calls on AT&T's 3G network. I find that making and receiving phone calls while connected to 3g or HSDPA is very unreliable on my Fuze. The phone seems to always connect to H whenever there is any signal available, even if the signal is very low and unreliable.
I will sometimes recieve a call while connected to H and the person cannot hear me at all. I'll look at the phone to see that the H signal strength is very low. Instead of smoothly switching to Edge, the phone completely loses signal and drops the call. After having no signal for around 10 seconds, it will then reconnect to Edge and have 2 or more bars of service. Why couldn't it just switch to Edge without dropping my call? Any why hang on to an HSDPA connection if signal is unusably low?
I see other AT&T customers with 3G phones (Bold, iPhone) and they don't seem to have this same issue. Their phones can remain in 3g mode and work just fine. My only choice seems to leave 3G turned off, but switch it on when I need a fast data connection (a terrible solution).
I used to have Verizon and they just connect you to both their 3g and 2g networks at the same time, you can even see 2 signal meters on most phones. They use the 3G (EVDO) for data and 2G(1xRTT) for voice or data, when 3G is unavailable. Why can't my Fuze do the same thing on AT&T? Clearly, 3G doesn't penetrate building as well as 2G and the phone needs to use both, seamlessly, to work properly.
Just for background, I am using a Fuze with the latest EnergyROM and Radio 1.14.25.35 and matching Rilphone.dll. I have noticed this behavior with other roms and other radios also. I can't remember how stock worked since I haven't had it in such a long time.
Does anyone else notice the same behavior as me and does anyone have any ideas on how to improve the way the phone manages 3G vs Edge during phone calls?
Thanks in advance for anyone who can help me understand and resolve this problem.

different radio
Drop into the ROM section, hit the radio thread. I found better luck dumping the stock radio on the Fuze, and installed a different one.

Any particular one that you recommend? Ideally, a radio that doesn't use 3g unless signal is reasonably strong would be best. Ive tried all of the official Fuze ones without any change in the behavior I described at all. Based on your signature, it seems you are currently using the same radio as I am...

I found the newest Xperia radio (1.16.25.48) to be very satisfactory as far as signal strength goes - in fact I had more bars of 3G and dropped a lot less calls because of it. However, you need to be Security Unlocked to flash your phone with that radio. The only problem with the Xperia radio I had was the pitiful GPS accuracy.

sopranos16 where are you located? There are a few cities where users have been complaining about the 3G network. NYC/Northern NJ and San Fransisco are two that come to mind. Check on howardforums.
I'm now using a Fuze because AT&T shipped to to me to replace my Bold which will drop 5-15 calls a day in NYC. I don't believe it is a problem with the Bold, I have other lines with 3G that have problems. But this is the solution they offered so I'll try it.
You cal also check the at&t support forums as there are plenty of complaints there too. I just got the fuze and haven't really tried it yet. See what happens on Monday.

I'm located in central New Jersey: Monmouth County. Edge coverage is pretty good but 3G tends to always have a weaker signal strength and occasionally drops out, especially indoors.

Well the first day in lower Manhattan and not one dropped call. I'll let you know what happens later in the week.

soprano, did you try the xperia radio? Let us know, I have had this issue for a while now...and your explanation was on the head.
Think I may just go ahead and security unlock my phone.

[Q] Signal strenght

Hi,
I' ve just bought a 820 and I am up to now happy with it ...
However I have the impression that the signal reception is quite weak; do you have a similar problem?

is OK, compared to BB and Desire S at the same place-

Thanks...
In fact at some "difficult" places I get only one bar (or even no signal - but rarely) while with my old Samsung I had practically always enough signal.

I had issues with signal prior to the update that went out today for my phone from Tmobile , now I have a good signal everywhere in my house. Can sit on the couch and text,web surf, and whatever else at high speed.

I have Nokia 820 and I also face problem of the signal strength fading out - call getting dropped and after a few seconds the signal comes back. Is there a solution for this.

Reception on 5 vs 4

Hello,
I have my Nexus 5 on order and it's currently in route via UPS. For those of you that already have it in hand, whats your opinion about it's reception vs the Nexus 4's? The reason why I ask is because my nexus 4 has crap reception in my office and I can't get a signal while co-workers on the same network carrier can get a signal just fine (a weak but reliable one). It doesn't help I'm in a basement behind 3 feet of concrete and steal beams, but if I go to the stairs I get a signal right away.
If anyone who previously had "bad" reception in certain areas could test this with their new Nexus 5 and share the info that's be great!
Because of my bad circumstances and office location, I'm hoping I can get a basic signal for just talk/text. I'd be fine without data since I don't surf the web on my phone while at work.

Sooo.. got my N5 yesterday and I normally have bad signal at home. I had the same bad signal so assumed everything was the same.
Got to work this morning and previously where I had a great signal with my N4 where I sat I get literally no cellular signal on the N5. Tried forcing down to 3G/HSPA and still nothing. As soon as I walk out of my area and close to the front of our building my signal comes back almost full.
Anyone experiencing these same issues? Not too pleased with this but I'd feel better if other people are affected at least.
*edit*
So in a completely random way I turned data roaming on and off just for ****s and giggles and within 5 seconds of turning it off I all of a sudden had a full HSPA signal. ????? It appears to work flawlessly now.

Weak Wifi reception

A few users reported weak WiFi signal strength on N5. Good WiFi signal strength is very important for me and this is one of things I like on my current SGS, so Im wondering how good is Wlan strength on yours N5 ?
Also Androidizen posted video about WiFi problem:

I received my N5 yesterday and i am facing this weak WiFi signal problem.
I compared it with my Iphone 5.
i was 8 feet away having my back to router, iphone 5 showed full strength signals while N5 showed 3/4 signal strength.

Ive had my nexus 5 for a few days now, and the main thing that is annoying me is the wifi, the signal is so flaky one minute im on full bars, next minute its on 1 or 2, then back to full. this can be in line of sight with the router. Ive tried a few routers at home and at work, same issue. I have tried an iphone, nokia and samsung and they all have a much better range. I'm contemplating taking this back now and getting a refund, as i don't think its acceptable. does anyone else get this constant fluctuation?
I have also noticed when you put your hand over the top of the phone the signal can drop completely. Not taht i do this, but other phones i have do not suffer with this.

i take it not many people are seeing this issue, are others with the phone able to check the wifi range and fluctuations in comparison with other devices. How can it go from full bars to 2, then back to full constantly when other phones are solid. Trying to work out if its worth exchanging for another. Speeds just change from say 72mbs to like 19mbs non stop. Thanks

Side by side with my Nexus 4 I'm getting the same strength and speed.

Do not use the bars when comparing signal.
Download an app that shows you the actual signal level in dbm. Bars can be set to whatever the developer wants. I could make you have full bars at -110 dbm which would be a useless connection, but still show full bars. For the most part, you should disregard them.

Would be possible to boost WiFi reception with a software tweak? Even if Google doesnt provide a fix, could be WiFi signal strength increased in custom roms? I hope some developer will know to answer this.
I have chance to get N5 32gb next week and I really want it, but since Im a lot in other countries, good WiFi signal strength is very important for me (to connect on WiFi hotspots)
Thanx

Is it an issue of signal strength only? Does it ever disconnect you completely? "Strength" would be much less of a concern than disconnects, now THAT would be annoying.

I have read that some N5 owners lost WiFi connection when they were about 10 m away from router. This is unacceptable IMO. I hope software tweak can boost WiFi reception.

I confirm the weak wifi too.

signal
i have nexus 5 16gb white, signal is very very weak!!! i have N4 and GN and have perfect signal!
the problem of weak wifi, is all about the nexus? we have to wait for a fix or should call google and give it back?

I'm facing the same issue. I'm few feets from AP and I'm getting weak and unstable signal. The worse thing is that it is not picking up signal from my main AP (Edimax) at home... It does not "see" the network at all even all other devices at home use it fine.

Very weak signal with this phone, I got full bars on my previous phones in my office but now only 2 bars. If you put your hand near the top of the phone the signal completely drops.

Same issue here, very weak reception. No issues with may tablet or laptops, but Nexus isnt getting good signal. White 32GB.

Yup weak signal. Initially it didn't want to connect to 3g but that was fixed with the service menu. And now I am noticing weak WiFi signal.
I'm guessing this has to do with the antenna.
Its easy to open the phone I'm going to crack it open and see what I find.

Have you folks tried going into your N5's WiFi settings & look under the Advanced submen (press the 3 dots on the lower right of screen)
Tried turning off 5 Ghz band if your router is on the typical 2.4 Ghz band - and if you have the newer dual band N router, enable your 5 Ghz band - could be interferences from other nearby devices or AP ??
Install the free app, Wifi Analayzer from Play Store & run it - take a look at your AP's signal strength, try switching to a less congested channel since the airwaves are shared, regardless which of the 11 channels you are defaulting to ...
Mine is running just fine, -60 to -50 dBm with the N home router behind 2 sheetrock walls.

Compared to my Galaxy Nexus and Galaxy SIII, I have superior Wifi Signal on my Nexus 5 to a very positive surprise...however network drop outs for Cellular connection is quite annoying...

guys try to disable the wifi optimization under advanced wifi setting and set the band to 2.4 . it worked with me :good:

I have to use my 2.4GHz connection because the phone didn't work at all on the 5GHz.
Sent from my Nexus 5

I have this problem too. Sometimes my signal is so weak that it disconnects with the router and falls back on 3G.
I tried everything. Just went into Safe Mode, but Wifi is still weak, it doesnt matter.
I tried to only use 2,4GHz and turned Wifi optimalisation off. Still the same weak signal.
I tested it with the app "Wifi Analyzer" If I stand next to the router it gets about -50dBm. Then I tested it with my brothers Galaxy S2, he got -40dBm. Thats a difference of 10dBm. -40dBm is a stronger signal.
We tried it at the 2nd floor, and he got a better signal again. So it's obviously my Nexus.
Android 4.4.2, stock, no root or something. Google come with a solution please. My previous phone had the same ****ty Wifi (HTC One X).

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.
