[i9505G] Signal/Reception problems on AT&T - Galaxy S 4 Q&A, Help & Troubleshooting

Anyone here had any decrease in signal/reception strength when switching to the S4 GPe and running on AT&T?
I used to have 4/5 LTE bars in my home constantly on my iPhone 5 but now I only get 3 bars top (usually only get 1 or 2 bars indoors). I have switched to the correct LTE plan and got the appropriate SIM card, plus I have factory reset my phone but nothing has worked. Any help would be appreciated. I just hope that I don't have to return the phone. Thanks

How's the call quality? Signal strength bars do not reflect actual true signal strength. My older Motorola shows almost full strength signal while the GS4 only shows one, two, and rarely 3 dots but the calls are clear on the GS4. I am not saying this is alright; just merely asking about call quality.

Pretty good actually. No problems whatsoever with call quality or dropped calls

After a day or so the phone now only shows the H instead of LTE. But signal "strength" is better having H only. Could it be that my LTE signal isn't strong as I thought it was? I will call AT&T to see if my account is provisioned correctly (even though they assured me it was) after the SIM change.

Poor Signal Reception?

Anyone else noticing a lower signal reception with this phone?
I am coming from an iPhone 4. Previously at my house I was at 4-5 bars, now 2-3.
At my work I usually had 2-3 bars, now I get no signal to 1 bar.
I was trying really hard to enjoy the phone but now that I have seen the signal at my work I think it's going to have to go back
I wonder if the Inspire would get a better signal.
Update: It's not just the bars, I make calls and texts regularly at work with my iPhone and have never had a problem. With the Atrix it is dropping to no service and I can not make a call or text.
I was just noticing this same thin as well, i'm coming a captivate and where i normally have full service, the atrix gives me 2-3 bars. That said however, i don't notice much of a difference, if any at all, in the speed of things
Signal bars are different from phone to phone. I wouldn't trust those to much. However I find this behavior odd as I get better reception on this phone vs my old one. A lot better as in 2 - 3 bars better. Were you able to make calls on you iphone when it actually had the 1 - 2 bars at your office?
Vaires from phone to phone, remember when iPhone 4 showed higher signal then it was supposed to? then apple pushed the update
Yeah I made calls and texted regularly in my office, with the Atrix it drops service enitrely (says no service) and I can't make a call or send a text
I wouldnt care about the bar difference if it wasn't for the actual no service vs never having a problem.
That is interesting , my captivate had 0 to no service in my office, while the atrix has atleast 3 bars of edge.

Comparing using the bars is not going to work across different phones, besides the iPhone 4 was known for reporting more bars then other phones.
In Android go to Menu > Settings > About Phone > Status and note the signal strength.
On Verizon you could update what they call "roaming capabilities". It's not really roaming, its more like manually updating or sync'ing tower or geographic locations. It's supposed to help some issues with signal strength.
Does ATT have a method to manually re-sync in this fashion?
HAROLDS Did u even read the bottom of my post?

i think that means your Captivate still tries to look for a 3G signal but the Atrix is so weak that it cannot find any 3G signal and therefore it automatically starts looking for the Edge signal.
I am saying this because I also noticed the same behavior inside my apt building elevator.
This is interesting. I guess I'll find out tomorrow, but several of my friends and I have been noticing that deadspots with our N1's and Captivates. Like no signal, no voice, no text, no data. In the same locations iPhone 4's are good to go on everything. I volunteered to be the guy that gets an Atrix to see how it does. This thread has me worried.

What do all you atrix users think about the cell radio/signal?

i know with my droidx, i got fabulous cell reception and signal. Motorola is known for it. when i had my samsung with the same provider, i had crappy signal..
what do you think? good cell signal?
Mine is fantastic. One dropped call, and I was in a tunnel.
-95 dBm instead of -110 on my HTC Hero (I live in a terrible signal area)
For me the signal is terrible when go to my office. Most of time no signal.
I'd changed from telco companies and all they worked perfectly I got no complains about it.

I've noticed a small increase in reception from my iPhone 3G, but not that much of a difference. In some of my classrooms, I used to get no signal on my iPhone, but I get one to two bars on my Atrix. I haven't been reverted to EDGE yet, though, so I'm not complaining.
Works fine for me
Works well for me. Got crappy reception in my office, but that has been consistent between phones, so no biggie.
No dropped calls and I lose signal in one building I rarely go into but it has a sheet metal roof and walls and no one gets reception in it.

I'm quite satisfied, I've been in a road trip with a guy whose phone was an iphone and our reception was the same or even better
I've been getting better signal on my Atrix then I got on my iPhone 4 especially in areas with weaker signal.
Im haven't had a single dropped call since I got my atrix compared to the lg expo I had previously. I must say that I've had such good reception I'm impressed!

Signal is great everywhere than my office building. I'm very happy with the call quality, which beats my nexus one's.

I am very impressed with the reception I get with this phone. I too live in a terrible area when it comes to cell coverage and this phone seems to be doing a better job than the past 4-5 devices I've used.
Most samsungs were close to unusable where I live.
At work I have a very poor signal indoors (-100 to no signal). With my BB 8900 if I walked out to the door I could make a voice call. However with my Atrix I kept dropping calls after 30 sec or so. I got a microcell to fix that problem.
I am having a reception issue. My Motorola Atrix shows 3 or 4 bars and suddenly drops to 1 or no service for a second and goes back up to 3 or 4 bars.
I live in NYC and never had this problem with my Samsung Captivate. Most of the time the phone does not even show the full 5 bars, mostly 3 or 4 and occasionally 5

Nexus 4 Signal Strength (Bell Canada)

I'm considering purchasing a Nexus 4 (hate my iphone 5!).
Anyway, I've read a few comments about signal strength problems (ie. getting 1 or 2 bars less compared to other phones on the same network).
On my iphone 5 while at work, I usually get a pretty weak signal (1 to 2 bars), but I can still use it for web browsing and usually can stream music with no problems. I'm with Bell.
Can anyone who has the Nexus 4 with Bell comment on signal strength?
Thanks
I have a nexus 4 with Bell and get 4-5 bars most of the time , only one dropped call since I bought it in November

I'm a Virgin Mobile subscriber (same Bell network) and switched from an iPhone 5 about 2 months ago. In general I've found the Nexus 4 to provide as good if not better signal strength than the iPhone 5 did. At home I could barely get LTE on the iPhone but on the Nexus 4 I have 2 to 3 bars of LTE. Same issue at work... I could not for the life of me get a LTE signal sitting at my desk which is right beside a window... with the Nexus 4 I'm also getting 2-3 bars of LTE. Some of this may just be a difference in how the two phones display relative signal strength or how they decide when LTE signal is strong enough to use over 3G, but in general I find the Nexus 4 performs a bit better than the iPhone 5.

Signal strength issue

I received my XT1053 T-Mobile Moto X this past Thursday and have been having signal issues since then.
People I've spoken to notified me that voice quality they heard was choppy, although I heard them fine.
I also noticed that I've been getting anywhere from -95 to -105 dBm, while my old phone and other phones receive -65 dBm to -75 dBm around the house.
These numbers are within my house and outside my house.
I'm running unrooted/all OTAs. Safe to assume something wrong with this particular phone?
Edit: When I set to network type to GPRS (2G), I'm getting a good -58 dBm. When I put it back on LTE I'm getting -100 dBm again.
So when I'm on LTE its just not connecting to the closer tower?

I've had the same problem on 3 moto x's. I think its only the tmo version that has this problem since no one else is complaining about it.
EDIT: Maybe not the same problem. Mine happens on HSPA and EDGE as well. It looses signal completely for hours.
The way an LTE signal strength is measured is not the same as 2G or 3G, that can explain quite a large db difference. Voice calls don't use LTE right now, your phone will switch back to HSPA/WCDMA/2G for voice.
Im on a dev edition verizon phone. Ive noticed Im getting average 103 dbm lte where as my other phones are at about 97. Voice 3G is about 85db which is good. Wondering if there isnt something wrong.

You're right. It does switch to HSPA+ and signal strength does increase back to -60 dBm while I'm talking.
So the phone shows 2 bars while I'm not on a call is simply because signal strength is measured differently and it doesn't take into account the different network type?
I wonder why two different people on two different days told me they were hearing me pretty choppy (I heard them fine) and I even had a dropped call, all within like 3 days of owning the phone, with pretty much no issues that I can remember with my previous phone (it was an HSPA+ phone).
I'm not sure what to do...

Maybe turn off voice privacy in phone settings.

I agree with the poster that LTE is just measured differently.
I have the N5, HTC One, and Moto X and they are both usually is the 90s or 100s for LTE. The X is usually 5-10 dbm better than either the N5 or One.
Best reception phone Ive had thus far :laugh:

Poor 4G Lte signal

I have N-910F variant of note 4 with NK4 fw. Just after I got it, I noticed that almost all the time I have one or two bars on 4G network. Just outside my house I have full signal on my galaxy s5 on the same network (3 Sweden). But on note 4 I get just two bars, and sometimes just one. While browsing this thread, i noticed that almost every screenshot has only one or two bars. Anyone else having this problem?
Yes. I'm in South Africa. And also feel my s5 works better than my note4 not just lte but also call quality is not as good. It also seems to struggle to get online sometimes when not connected to WiFi.
How many asu do you have? You can see asu in "about phone"
I have 1-4 at home.. Outside it reaches ~13 max
