Why does Samsung always have terrible signal? - Galaxy S III Q&A, (US Carriers)

My first 2 androids were the htc hero and evo. I then switched over to the Epic touch 4g GS2. When i first got that phone, i had extremely weak signal strength and would encounter numerous dropped calls, as well as a complete loss in signal. Eventually, after dozens of modems that i flashed, the signal got better.
I now have the gs3 and am experiencing the same issues that i had when i first got my gs2. Will Samsung ever be able to make a modem that is worth a damn? Also, is this only a Sprint thing, or do other carriers have the same issues?
I've had an airave during in my closet because it refuses to work and just had a continuous blinking yellow light, so that's not a solution.
Any recommendations would be greatly appreciated.

I wouldn't know about the sprint gs3, but I heard the 3G isn't that great. I'm getting pretty great signal on hspa+ and lte on att

Yeah, I've owned a Thunderbolt, Droid Charge, Galaxy Nexus, and Galaxy S3 all on Verizon and have noticed that none of the Samsung phones have as strong an LTE signal as the Thunderbolt. I heard Moto's phones get better reception than any of the ones I've owned. On the bright side, the GS3 is noticeably better than the other Samsung ones I've owned.

I get great service on my Sprint S3. I typically have at least 4 bars of coverage wherever I'm at, besides a few places.

I get a decent signal everywhere but my apt. I'm in between 2 buildings, which may be blocking the signal. Even so, i usually have 0 bars or no signal. I didn't have this issue with my htc phones. I guess I'll call Sprint and try to get my source airave working.

That's what I'd do, because I have friends with the att Galaxy S3 and I get better service than they do.

Is there any LOS???

I had the S2 and it always seemed to have signal issues and updated its radio every week it seemed. How's the signal with the S3 so far?
No issues. Radio solid fast 3g insanely fast GPS locks. Buy it
No

This is one of those threads that is meaningless information or worse because the mods combined the forums and the posters failed to flag their carrier. So-called "signal" issues are carrier-specific.
On my sprint s3 I don't have the "los" bug but signal on this phone sucks. Anyone who tells u different is lying. This may be one of the weakest radios on any phone. My photon would have, 4 bars on sprints network where this one will be roaming
Hopefully a radio update will fix these issues

This fits the pattern of other anecdotal reports by some users of Sprint LTE-capable phones, not just the GS3, in some areas.
Since the whole Sprint network is being rebuilt right now on a localized basis, my bet is that these symptoms have something to do with how the new LTE phones interact with the legacy network, or at least with certain regional segments of the network that are under construction right now. Whatever is going on, Sprint is not being forthcoming about the issue.
However, this is a Sprint-specific problem, having nothing to do with the original post, which apparently does not involve Sprint.

Actually I do know how to do a prl and profile update. That doesn't fix a bad radio. The radio on this phone sucks plain and simple. My mobile network in battery settings is all green with blank spots all through it where it looks as if I had no signal but I have a airwave in my house. 3rd s3 and all 3 had this problem so far

I'm just going to assume u have never owned a photon because that's what I came from. This phones radio compared to the photon sucks horribly. I roam at the sprint store. Reps there said they are hoping it's due to the network upgrades

No it's due to Motorola holding several patents that allow the cdma radio to be better in their phone.....no other cdma phone will get as good of coverage....HTC LG doesn't matter Motorola is the best coverage of any phone cdma wise but their phone sucks other than that....
Most people forget Motorola was a radio company before they made phones

How is the Radio?

Samsung devices don't have the best history with Radio quality. I am debating an upgrade and trying to decide between a DNA and N2 on Verizon. I know the S3 and a few other recent Samsung devices have had problems with dropped calls, weak signals in fringe areas, etc. The DNA uses a Qualcom radio so it's pretty stable. It looks like the GN2 is still using their own in house radio design?
My wife's iPhone5 and my N2 seem to get the same signal strength everywhere we go.

After coming from the galaxy nexus anything would be an improvement. But, actually the radio has been great for me

The radio pales to the quality in the DNA (which is likely more due to antenna), but is miles ahead of the galaxy nexus.
Personally working in a 4G fringe area, I had better handoff on my thunderbolt than the N2. Both devices forced into 3G I think the thunderbolt performed better on 3g, while the N2 does better on 4G.

Just want to repeat this. On the galaxy nexus I had to keep my phone in 3G just so I wouldn't constantly drop data. This phone however has been great! My wife has the S3 and she also has great reception and data reliability so they must have fixed something.
It's the first Samsung phone that gets reception similar to my old Thunderbolt. My Droid Charge, Galaxy Nexus, and Galaxy S3 all got poorer reception than my GN2 and TBolt (the Droid Charge and the GNex were tied for worst).
Thanks for all the feedback here. How would you say 3G connectivity compares to an old Motorola Droid X (Current Phone)

LOL, no kidding (I have had both devices)
Personally, I think the GNEX was the biggest POS ever made.
I actually loved my Droid Charge (i still have it somewhere) and after a TON of mods and radio swaps etc it was way way better than I could ever get the GNEX to work.
That being said, the N2 radio is hands down better than either one although it is not as good as the Rezound I still use occasionally and about equal to or maybe slightly better than my Wife's Galaxy S3.

Funny, I've only had the Note 2 a few days and haven't been in any good 4G areas yet, but I find so far that it's much better than my Rezound. Where I live I only have 3G, with 4G being across the lake.. my Rezound would pick up 4g for 30 seconds at a time very rarely (like once a week), and never transmit data, but the Note 2 gets 4g from there off and on pretty regularly, at least in my house. It's 3G signal also seems more consistent, at least going by signal bars and how it "feels" to use (haven't actually compared dBm). The Rezound would routinely drop it's data, sign out of Google Talk, take forever to re-establish it's connection, etc. I HAD to use it on WiFi or it was basically unusable. The Note 2 so far has been great.
While I have Zero issues its the radio, if your coming from a Motorola Device, it's not as good. Motorola just has killer radios. That being said, I have had no problems with the Note 2
I'm in an LTE market in Maryland and my signal is horrible. I can be only a couple feet away from any building entrance and my signal goes out. No 4G, no 3G... just straight up no signal. And the thing that kills me is that the icon will say it's on LTE. I have to be literally standing OUTSIDE to get a good internet connection. And tethering?.. forget it! My connection is intermittent at best. Frequently drops out to the point where I can't even download from XDA via the phone's browser. Love the Note II, been onboard since the first Note but... this is making me think either I have a bad radio or my choice to switch to Verizon from ATT wasn't a smart one. I need PRL's people. NOW!

Coming from the rezound and a inc4g for a week, this phone is just as good as those radios. I can get a 4g signal inside my work where the S3 can't. The exynos set is absolutely badass on this phone and the reason I didn't buy a S3.

I beg to differ. I had the Razr Maxx before my Note 2 (and Droid X before that) and so far I'm getting exactly the same amount of signal everywhere I go. Best radio on a Samsung phone yet. Very happy with it.

PRL only effects the 3g side of the radio from what I've read. I would try to get a replacement device

The radio here is southern orange county has been very good.. better then my Gnex.
I personally came from the Galaxy S3 and the difference in service quality is astounding. Before I got the GS3 I had a RAZR and had excellent service, with the GS3 I couldnt even send texts without hitting resend 5 to 10 times. I had to get something different so I went with the Note 2 and this phone has as good if not better service that all the Moto phones I have compared it with and has way better servixe that the GS3.

Signal Quality

Has anyone who owns the Droid DNA with Verizon tried out the Galaxy SIII at all? I currently have the GSIII, but may switch to the DNA because i'm having problems with the signal strength at my house and a couple other areas. I've heard this is an issue with the GSIII, and have also heard the DNA has much better signal strength on the Verizon network.
I can't say anything in comparison to the S3, however I get excellent signal, especially compared to my Galaxy Nexus.

I got my dna because my s3 had bad signal.
Overall I get signal everywhere and that's one of the reasons that I haven't gotten rid of the DNA yet.
I love this phone!!

I have the DNA and my girlfriend has the s3. I can tell you that the DNA is the better of the two radio wise.
I have the S3 and DNA and hands down DNA has the better signal quality (tested using network info app free from the market). In areas where I get 4 bars on my DNA, I will get 2 bars on my S3.

Thanks all! I think i'm going to be switching to the DNA this morning!
Hands down HTC radios are far superior to Samsung.
What are your opinions on the non-removable battery in the DNA? Any issues? How long does it last on a moderate to high use day?
The signal is great the battery for my is on par with my other phones I came from the optimus g on att which battery wasn't consistent and this one has got me through the whole day depending if I download a Rom and flash it but so far its good for me

About the same as I get with my S3. On a full charge about 12-14 hours with about 4 hours of on screen time.
I dropped the gs3 for the DNA over signal issues. In fact.. after calling tech support a few times they sent me a DNA as a replacement.
Batter is as good or better, screen is amazing. Wireless Charing is awesome

The signal strength has been far above what my Thunderbolt was. I get 3 bars (of 3g) where I had no 3g in the past.
Battery life has just been "meh" for me, I have to keep some form of charger handy.
I also came from gs3 due to horible signal issues. I do miss the sd slot but have since moved my music to the cloud so that had been resolved for me at least. As for non removable battery I don't mind at all since I get the same battery life as I did on my s3
Sent from my HTC6435LVW using xda premium
If you judge by number of bars the DNA looks way better. If you judge by actual signal strength the DNA is only slightly edging out the Galaxy S3. However this phone hasn't locked me out from receiving and sending texts yet. So I'll say it is better in that regard.
The call quality and signal strength on my DNA are WAAAAY better than my last phone, the EVO 3D, but I am coming from Sprint so I guess that's to be expected. Battery life for me is not an issue since I am not a heavy user but it is better than my EVO 3D, if that means anything. I went to Verizon for the 4G because Sprint doesn't have it in my area and the 4G is screaming fast. Not sure if it's the phone or the Verizon service.
Signal on this device is sick! I wouldn't trade it for anything. I went from my Dinc2 to this, had barely 3g at the house to having 4 bar 4g

Note 3 vs G2 reception

Hey guys, torn between these 2 phones. Triband maybe the determinh factor but considering how slow sprints 4g rollout is taking, it might be a non factor for the time being. How is the signal strength on the G2? My galaxy s3 signal is poor and my buddies nexus 4 has poor reception. How is the reception for you guys?

I think Samsung is notorious for weak antennas. My GNex struggled at my desk in my office but the G2 fairs well. A co-worker with the Note 2 has poor signal while the woman next to him with an iPhone is fine.

I agree with this one, Im on Verizon and Ive had so many OTA updates on Samsung devices and every time its at least a radio update. They have gotten better about this over the years but thats not saying much. I still see them hop in and out of coverage and that really takes a toll on battery. The G2 stays on 4G all the time when im not using wifi and it has no problems, its always picking up 4G especially indoors the signal stays strong.
Im sure triband is an attributing factor here too as well

Very poor reception

I just moved and have extremely poor reception at my home. The vzn engineers actually drove the street and proved it t be a dead zone. Network extender works poorly and i rely on my phone for business. Verizon will let me out of my contract w/o etf because of the poor service. Have spent hours on pbone with tech support. Apparently at&t gets better reception here. Anyone have any thoughts about their speed/service in north dallas? I hate changing but this is horrible.
