    Coming from an iphone 4, and my signal is a lot weaker at my office here in Midtown NYC. 4G is showing on top, but nothing is connecting. On my I4, I had no problem with 3g. For some reason my S4 is not attempting to connect via 3G either.

    Is there a way to disable 4G and use 3G only at times when no 4G signal is available, and I dont have my battery destroyed by the phone searching for a 4G signal?

    Thanks
    on the S3 you can't do it *easily*...but it can be done.

    You have to find a way to get to the Device Info screen. I get there by using Battery Monitor widget (under "Tests"), then change the network type to "CDMA auto (PRL)". To change back to turn 4G/LTE back on, you have to go to "Settings --> More Settings (under applications and network) --> Mobile Networks --> Network Mode" and change that to "CDMA/LTE/EVDO".

    Again, that's on the S3...the S4 is possibly completely different.

    I came from a Droid Razr Maxx and my signal strength appears to be about the same as the razr maxx. Of course I have only used it a day and been on wifi most of the time but the 4G I have used seemed fine.

    Again, my comments here are as a current S3 owner...

    The thing about the S3 is that when in good 4G coverage area, the phone works great...it's on the "fringe" areas when things start to get dicey. It doesn't seem to do the switchover from 4G to 3G very well, so sometimes it seems like it's constantly switching back and forth and/or not switching over when appropriate (trying to use a really weak 4G data vs. stronger 3G signal). Also, especially in 3G areas, it seems to get a much weaker signal than other devices, like iPhones, on the same Verizon network. Again, just my own observations.

    Honestly, I'd have to say that radio quality has probably been my *only* consistent complaint regarding my experience with the S3. It has otherwise been a superb device.

    Judging by the posts on this issue over in the S3 forums, it does seem like Motorolas seem to have the best reception for Android phones on VZW, and iPhones are pretty good too...both better than S3.

    I live and work in a pretty solid 4G area, so I haven't had too many issues owning an S3, but I do notice the signal issues from time to time when traveling. Subscribed to this thread because I'm considering an upgrade to the S4, and curious if it has better reception than the S3 does.

    Lol, can't argue with that. But they are starting to get it under control recently. Note 2 has good signal reception just as good as any Moto, HTC phone. GS3 is known to have good 4G but weak 3G reception. I think that's firmware issue as it's using qualcomm S4 multi-mode chip that's used by many other devices without much 3G issues. I hope GS4 is more like Note 2 than GS3 on signal reception. Time will tell.

    Haven't purchased yet, but did take a look during my lunch break. Signal was within 1-2dBm of the RAZR MAXX HD they had right next to it...

    That's pretty solid then. And I am sure with updates it will only get better.

    Surprisingly, my S4 has had identical reception as my iPhone 5. I'm VERY happy about it

    +1. My office building in NYC is on the fringe of signal sometimes and I dont want my data to get any worse.

    I got this phone yesterday. Coming from HTC Dna. The signal on this phone is horrible, and I am not counting signal bars. I also find it takes long to find 4G when it loses it. Some ppl may say don't worry about signal, but to me that's the most important, whose need a phone if you can't make a call or surf the Web. Also from Brooklyn nyc

    signal is adequate but it is a step down from what Im used to. Speaking of 3g and voice. 4g LTE is not in my area yet.

    I just received the Verizon Samsung s4 yesterday. I am having a difficult time picking up a 4G LTE signal at my home with it (If I set it on a counter and don't touch it I get a signal). I also have a Verizon Jetpack 4620. The Jetpack pulls in a 4G LTE signal at -112/-113 db (and shows two bars). When I get a signal on the s4 it shows -114db. Otherwise, the 3G signal is strong at -89db.

    The Speedtest.net app reports between 5.5 and 11.5 Mbits download and between 300-400Kbits upload when on 4G LTE.

    So far I think the radio on the S4 is on par or better than the S3. But I havent done any speed tests confirming this.

    The S4 is not nearly as strong as my DNA was and is slightly worse than the iPhone 4S.

    Coming from a Droid DNA, the signal strength on the S4 seems weaker/lower than the DNA but not substantially so.
    I too came from the DNA and have noticed that in my office I had between 3 & 4 bars of 4G signal. The S4 seems to bounce from 3G to 1 & 2 bars of 4G.

    If you want to use your phone as a phone, I suggest locking 4G out. I don't believe the reception problem lies with the radios in the Samsung. I believe it is the way the power is allocated to the various antenna signals being amplified in the phone. In my opinion (and that's all it is), the Samsung Galaxy S3, only has so much battery power available to it. The screen and the FIVE antennae are all competing for the limited power the battery can deliver. Samsung chose to go for an ultra thin profile rather than using a more powerful, and thicker, battery. By "powerful" I don't mean increased mAh. I mean one that can handle a larger current draw. The phone's reception will drop out when the signal strength is less than optimum, and the phone needs to use more power to boost the antenna signal to make use of that weaker signal. It reaches a point where the phone just doesn't have enough power to do that successfully. All of this comes from trying to understand why calls in my S3 were breaking up, or being dropped entirely. When I boosted the power to the G3 antenna in my S3, the signal strength rocketed up.

    It's half a solution. I live in an area where 4G/LTE is only partially built out. When I bought the S3, to replace my Droid X, there were a lot of places that I could no longer make calls, reliably. The S3 signal kept shifting back and forth beween LTE, eHRPD, EvDO_A, 1xRTT. Even without the Wilson Booster, I improved my ability to make and receive voice calls, by shutting down the LTE on my S3. Apparently that is a violation of some Google "rule", even though there are apps on Google Play that claim to do it. A popular app for closing off LTE on Samsung Galaxy phones, last year, was called Phoneinfo. It was pulled from Google Play and there were reports that users were not able to restore LTE on their phones after using it. :-( What made me start thinking that it was a power allocation problem was when I used the Wilson Amp on the S3, when I had LTE disabled. In an area where the Droid X could typically get -65 dBm with the amp,(which is pretty darn good), the S3 got to -21 dBm! That got my attention.

    I could be completely off base with my amateur phone tech analysis, but it's the best I've got. I was about to exchange the S3 for one of them famous Motorola phones, but now I will see if I can hang out for a while longer on the S3, without going completely nuts. Partial Nuttiness may have been in my nature before I bought the phones.

    Coming from an older Samsung Fascinate, I find the wifi signal about the same.....as far as the phone signal, it shows it to be a little weaker than the Fascinate, but I have yet to have any dropped calls.....I don't think you can really go by the amount of "bars" that you have, but rather if you experience any dropped calls, or loss of signal.

    I thought I read that the S4 had the same radio set up as the Note 2. I was talking to a Galaxy rep at Best Buy last week and he told me the S3 had a few issues that the S4 fixed. One was the S4 has more antennas than the S3, two he says there was a software issues that was causing problems in the S3 and now is fixed, and three he said that the S4 has Samsung components now made by Samsung in which the S3 had another companies components. He said other companies components were not functioning well with the Samsung components that were in the S3.

    Who knows, but that is what he said.

    I also moved from the Galaxy Nexus to the S4 and I am happy to report a very strong signal in compairson......although that may not be a good compareson because the Galaxy Nexus had terrable reception and switching problems. WiFi at my home show a strong signal but i am getting terrable speeds...I haven't looked into it yet but i suspect the problem is with the WiFi on the S4's (all my other wifi devices have good bandwidth).



    On the Verizon 4g map I am in a solid 4g area however i must be directly in the middle of two towers. With my Galaxy Nexus i was alway switching between 3g and 4g but with the S4 i stay on 4g with good speed.....I get faster speeds with 4g compared to wifi for some reason..... good thing i have unlimited data!!

    -Kesnik
    Maybe it's the router settings. First one is LTE and second is wifi. As you can see, I'm getting great speeds.
