Slow to switch up to 4g, 3g and even 2g - Verizon Samsung Galaxy S 4

I've had my S4 since VZW released it, and one of my only gripes is that the reception seems to be weaker than almost any other phone. Meaning, it seems to default to the weaker service wherever I am.
It is most obvious at home; on the 3rd floor I get a mix of 3g/4g whereas other phones have solid, constant 4g. The 2nd floor is the same. On the 1st floor I never see 4g, instead it is a mix of 3g and 2g whereas other phones are solid 3g. Sometimes I won't even have data service.
Even when I go out and I am in an area that you might consider a fringe zone it seems my S4 will default to the "lesser" service. And it also seems to take longer to switch up to the "higher" service when moving; for example where all phones will have 1x and then moved to an area where all phones will have either 3g or 4g, my S4 will be the last to switch up, if at all.
Has anyone else noticed this?

I'm noticing the EXACT same issues! My other phones (DNA,Rezound,iPhone5,etc) have been much better for both signal and switching.

[Q] 3G Reception Thread

How is your 3G reception on the Vibrant? I just purchased a Vibrant as a replacement for my aging and bluetooth handicapped G1 and I am disappointed with the 3G reception.
T-Mobile's coverage in my area is moderate, and the G1 has been able to hold on to a 3G signal in most locations. Typically, at home the G1 will hold on to 2-3 bars of 3G, and at work I am lucky to get 1 -- usually camps out on 2G with 4 or 5 bars.
The Vibrant pretty much always shows 0 bars of 3G while indoors, and may even flop back to 2G. It is fairly consistently on 2G in my home at 2 bars and at work I can only get 1 bar of 2G with this phone and spend the majority of the time with no signal at all.
I sat down and did some comparison between the Vibrant and the G1 and have found the following:
1. *#*#4636#*#* menu shows significantly worse signal levels on the Vibrant than on the G1, often times showing 0db and 0asu in the same location I am seeing -89db to -101db 3G on the G1.
2. The service menu on the Vibrant indicates a signal level which on 3G is fairly consistently 8db better than the one shown on the info menu. Interestingly, 2G signal levels as shown on the service menu seem fairly spot on with those shown from the info menu in Android.
3. The service menu 3G signal levels on the Vibrant seem consistent with those that I see on the G1 with a variation of perhaps only a couple of decibels.
That said, it seems interesting that battery usage on the Vibrant seems to indicate nearly 60% of its time with no service under cell standby when I get 0% in the same location with the G1. I am wondering if the time being recorded here is in fact the time spent with 0 bars being displayed even if the phone does, in fact, have a signal.
It is apparent that there is at least a software issue with the display here, as has been concluded in prior threads. However, ignoring the bar display I am wondering what others feel of the signal coverage with their Vibrant versus their old phone?
Does anyone have any experience with any of Samsung's other phone offerings? Do you think Samsung will post a radio update for this phone or possibly release one along with the GPS Fix/Froyo update in September?
I work in a position which requires me to be on-call a certain times during the year, and I can't really afford to have a phone that camps out at 60% no signal. I am really looking for reasons to keep this phone, as I like it otherwise, but practically, I need a phone that is going to receive phone calls. Any objective indications anyone can give that Samsung will continue to support this device may help sway my decision to keep it. My 14 days will be up on Thursday, so I need to make a final decision about keeping this phone before then.
Also, do any developers think that modifying the handling of the signal display in Android will cause a change in the amount of time the phone spends acquiring signal between 3G and 2G, or is this something that is purely handled within the radio firmware? If this is changeable, is this something that can be included in a future custom rom?
No coverage issues with mine.matches my mt3g in pretty much every location.

I made a call in the BOONDOCKS of NC, in an old river mill with 22 inch brick walls... NOBODY else was able to place a call other than me (all the big networks and nice phones).
I have pretty crappy 3g service here in new rochelle when at home the phone keeps fluctuating between 0-4 bars for 3G and the data speeds very inconsistent. Sometimes it even falls back to EDGE! This is pretty lame, i called t-mobile about it and they said there nothing they can do! If i am unhappy i should return the phone.
I live in NYC...
That is really all I have to say.
3-5 up speeds
constant 3g connection
The bars on the phone are funky though they look like there are none but you can still make calls. Its just the software is off just like the battery percentage.

If you're at home why aren't you on WiFi?
Seriously it's the most puzzling thing ever. 3G or not, I wouldn't be using it at home. Are you trying to replace your ISP with your phone or something?
You should do a search. Are you aware of the fact that -0dBm is impossible? The bars are off on this phone and the G1 is mediocre overall. It can hold on to a 3G signal for longer because your hand isn't blocking the antenna but the antenna itself is truly mediocre in fringe areas. Move your hand away from the bottom hump on the Vibrant. A lot of questions you're asking.. you're answering yourself.
I am not all too impressed with 3G coverage here at my home, but I mostly blame the network at my location and not necessarily the phone. TMO has spotty coverage near my house....period, and I live less than a mile from the tower. I have a Blackberry 9700 and it has similar issues with 3G. I've called and complained and they give me the usual "you're green on the map...return the phone....blah blah". I was closer to downtown Dallas yesterday and the phone had full bars and never got higher than -80dbm. Speedtest app showed about 3mbps downloads on average. I wouldn't say it was stellar but it's nothing like at home either. Only thing is my phone never automatically drops from 3G to E unless I am making calls. Once again the Blackberry 9700 does the same thing.
However, I am not completely convinced the phone isn't to blame either. I had a week with the new Motorola XT720, aka AWS Motoroi/Milestone that Magenta is/was rumored (who knows?) to get, and if Moto hadn't skimped on the CPU/RAM/screen/app memory of that phone I would have kept it instead of this Vibrant. That phone seemed to get much better 3G signal and HSPA was excellent compared to the Vibrant. I'm lucky if the Vibrant gets HSPA here at all. Overall network performance just seemed faster. It was quite obvious when I powered up the Vibrant the first time that 3G coverage is going to be an issue at my home with this phone.
FWIW my wife has an iPhone 3G which gets great 3G coverage here at the house on ATT. So I borrowed her SIM to test after I unlocked the Vibrant and it didn't make much difference. It did get 3G which I didn't think was technically possible until I saw that this phone has 1900 3G support as well as AWS. I do think the bars and definitely the battery indicators are not accurate whatsoever. I use Battery Indicator Pro and it's definitely obvious Samsung needs a software re-work.
Just because you live within 1 mile of a tower doesn't mean it's 3G or that there isn't something in the way of it's signal and your house.. I live within 1 mile of a tower and it's not 3G. It's supposed to get 3G soon.

Maybe I don't have WiFi in my house?
Maybe I would love to reduce my monthly expenditures by the $60 I throw away to Comcast?
I am well aware of the fact that -0dbm is impossible. This is simply what the phone is displaying. I also agree that the G1's reception is mediocre, but this phone seems worse than the G1. Blocking the antenna with my hand doesn't seem to make much difference on either the Vibrant or the G1.
I asked for objective answers to my questions which basically boil down to the following:
1. Do you think Samsung will provide support for the software on this phone (including the radio) over the long term ie. do you think there will be upgrades in this department?
2. Do you think this is something custom rom developers can address purely via modifying the OS?
Thanks for your snarky comments, but if you haven't got any objective input into the situation maybe this thread is not for you.

You're asking questions that we can't answer. Do we work at Samsung? No. Would stock Android fix this? Maybe.
It seems worse than the G1 because based on your comments the bars are having an affect on what you deem to be "worse". I've had tons of T-Mobile phones including the G1 and the Vibrant is not considerably worse than any. INFACT it will hold on to a 3G signal for longer than most. My CLIQ displayed 3 bars as -105dBm. Accurate? NO.

I know that nobody here is working for Samsung but there are plenty of people here who have developed for Android, and the question I am posing is if this is something that can be addressed in a custom rom.
I think my original post makes it clear that there is obviously a software issue with bar display, but I am wondering if this software issue is also causing the Android OS to force a switch to 2G in an instance where the G1 with a properly functioning display would keep 3G. ie, the phone is switching to 2G early because it thinks it only has -111dbm when it in fact still has -103dbm. I am not clear on whether this functionality is performed within the OS itself or purely within the radio firmware.
My hands are rather large, so holding the G1 basically covers the entire rear of the phone. The antenna is near the top of the phone whereas the antenna on the Vibrant seems to be on the bottom. Though holding both phones in various positions seems to have little effect on the received signal strength so far as I can tell.
The time spent without signal in cell standby I believe to be erroneous. I think it is tallying up that time any time there are zero bars, even if the phone still has a signal. This makes it very difficult to objectively compare the 2 phones. If the OS is in fact driving the switch from 3G to 2G this may explain my poor access in fringe areas as the phone will be constantly flapping between the two. If the functions that drive this behavior are within the AOSP source this could easily be something we can fix in a custom rom even without Samsung's help, even if a radio update would be ideal.

I can wrap my hand around the phone (Vibrant), either top, center or bottom and I do not see any change in either reception, call quality, network throughput or number of bars.

It is perfectly understandable that if he has good reception with a G1, an older phone, he expects at least a similar level or reception with a newer, higher end phone. WiFi would be considered a workaround.
I just received my Vibrant on Monday and it's sadly replacing my amazing Nexus One. I've noticed that the Vibrant antenna is AWFUL. Where I received 4-5 bars on the N1, I'm getting 1-3 bars now and it even goes down to Edge once every few hours.
Like the OP, I've been monitoring the db levels and they're frequently around -95 through -107. While my calls don't actually drop, the quality does get worse. I'm also getting many 3G connection errors when trying to browser or download apps from the Market. It's quite disappointing. The phone is made of plastic as well, so I'd imagine that the antenna reception should be better.
Being that there are only 2 pages on this particular thread, does this mean it's a fluke and others' phones are ok?

4-5 bars on a phone with a 4 bar scale?
Stop looking at -dBm on the Vibrant, it's not accurate.
If you don't want the phone to switch to EDGE lock it on 3G.

Thanks. 3G is spotty at best in the Des Moines Area, so I'll leave well enough alone.
So, in follow up to this, I had downloaded and installed RF signal tracker from the market and went driving around until I found a tower. It seems that via Android OS the best signal strength received was -81dbm and that was sitting right next to the tower. The phone stayed locked at -81dbm for a few miles down the road so I suspect this is peak signal on this phone which should really be something like -65dbm. I think this pretty much confirms that there is indeed a software issue with the signal display.
I also took some time looking at Android code and found that the bars are driven on GSM/UMTS by asu as follows:
if (asu <= 2 || asu == 99) iconLevel = 0;
else if (asu >= 12) iconLevel = 4;
else if (asu >= 8) iconLevel = 3;
else if (asu >= 5) iconLevel = 2;
else iconLevel = 1;
So figuring up the dbm values from these, I went ahead and created a new asu scale which is adjusted -8dbm from "normal" since this seems to be the worst case of the mismatch between the phone firmware and what Android is reporting and applied that within the market app Real Signal to try and get an apples to apples comparison of signal bars between this phone and the old G1. Unfortunately, the degree if miscalibration means we can't set a negative ASU so we don't get any meaningful display on Real Signal until we hit the 3rd bar. In doing this if I go to a moderate overage area I am seeing the bars I would expect.
After my little drive with RF Signal Tracker its actually pretty clear that discrepancy is really more like -15dbm, which adjusting the figures should mean that this phone in reality gets slightly better reception than the old G1.
It seems we should be able to workaround this in a custom ROM by doing one of the following:
1. Modify getGsmSignalStrength() to add the -15dbm to the returned signal strength value(hackish).
2. Modify the vendor RIL to compensate for the -15dbm offset when on UMTS. (Probably the proper solution).
I'm not clear on whether the vendor RIL code gets posted to AOSP...

I haven't done any detailed tests but I can state that in real world use, I am not happy with my Vibrant's reception. My G1 was very noticeably better at getting and holding 3G and Edge connections in the same locations where my new Vibrant won't.
Next to a tower on GSM(GSM/GPRS/EDGE) you should see -51dBm at the most with Android. W-CDMA is different because they really don't use -dBm to determine signal quality. They use power/noise.

[Q] Constant Switching Between 4G LTE and 3G

Hi all,
This question might have been posted already seeing as this phone is about a year old already. I'm running the STOCK ICS ROM OTA 4.0.4 unrooted. I've noticed that after the update my phone keeps switching from 4G to 3G and back but the problem is so bad that I lose every bar of signal (i.e. empty bars and of course no data) for at least a minute when the phone switches. I've already gone through the process of getting a replacement phone and I will need another because the receiver (speaker inside when I make a phone call, not sure what its really called) sounds awfully tinny and when the hang up tone plays the speaker sounds like its about to blow out. I lowered the in call volume to half, but it still doesn't work and my phone sounds tinny when ever someone talks during a phone call. I never had that problem with my old RAZR. As for the data issue, I am aware that I live in an old building because at the most I get between 3-4 bars of 4G LTE but sometimes as low as 2 bars. However, outside on the street I get full bars of 4G LTE and it still switches back to 3G on it's own. I have tried Motorola's restore connectivity app on the play store but that didn't work and I don't have anything like smart actions or LTE on/off app running on my phone.
Is anybody else having these issues? At first I thought Verizon sucks in my house but it doesn't I still get crystal clear sound on calls and text messages are promptly sent and received. I also, of course, live in a 4G LTE area with good solid coverage. As a control I have an iPad 4G LTE with Verizon on a separate account and it consistently stays connected to LTE. It never drops below 2 bars and the LTE of course maintains its fast speed. On the other hand, the RAZR, will switch between both technologies at least 5 times a day if not more. I know that they both have different radio technologies but they should at least be similar in some respect. I have also seen an iPhone 5 at the Verizon Corportate kiosk at my local mall. It's obvious there are repeaters but they are not for 4G because none of the phones are on 4G, they are on 3G. The iPhone 5, however, had one bar of LTE and it loaded up a web page just fine and I never saw it drop back down to 3G. I'm trying to see if there is a solution. Have any of the Jellybean ROMs addressed this issue?

[Q] Data connections being weird

First of all, I live in a suburb of Dallas which is completely covered in LTE according to Sprint's coverage map and I can affirm this by Sensorly and my own personal usage of my phone when I see 4G LTE in many places. However, lately I have noticed on the bottom floor of my house I usually get 1X or 3G, whereas upstairs I get 4G quite nicely. In other houses nearby (less than 1 mile), my phone doesn't even get data many times (and if it does, it is 1X) whereas other Sprint iPhone 5's are enjoying LTE in the same location.
Now I know our phone's have connection issues, but why am I not even getting 3G? Is there anyway to help force my phone to try and get more 4G signal because I know for a fact Dallas has pretty decent 4G coverage? When my phone goes into 1X it also seems to be sucking up quite a bit of battery. Any help is appreciated!
I am running MeanBean 3.09, S-ON, with the newest Bulletproof Kernel.

MeanBean has the Roam only option baked in, just go to settings - mobile network and set it up... The battery drain is "normal" when the phone doesn't have a good signal... Roam or use wifi... I know it doesn't make sense but that's the now network...

Something is seriously not right with the One LTE antenna

This is a typical speedtest where i work with S4 vs my One.
As we know from my other thread http://forum.xda-developers.com/showthread.php?t=2451516 the S4 is a complete and total joke when it comes to voice recognition so I swapped it out for the One. The only problem I have with the One as the voice recognition is second to none, is the data speed. Some days it decides it's not going to pick up an LTE signal under any circumstances and some days it does but it seems that the download speed appears to bleed off to almost nothing as seen in this pic. No programs are running at the time I did the speedtest here and both phones ran their speed test separately.
Something is not right.
I'm not having that trouble with my One. I'd take it back and get another. My LTE is usually around 20Mbps and I've had it as high as 37Mbps.
Something is wrong with your phone. While I wish T-mobile had better coverage, when I am in a good area I am getting fantastic speeds on my One.

While I don't have two tmo LTE phones, I did switch from straight talk and my tmo LTE is horribly inconsistent while the ATT LTE signal on the same phone is solid wherever I had reception. It also has a weird issue with speed test in particular where it keeps routing me to a server in Denver or Albuquerque even though the location services work fine.
Tmo hspa isn't great in my area but still more consistent by far. I may just switch back to straight talk even with the cap as I have zero issues on ATTs LTE network and don't stream anything other than music. The phone is by far my favorite, even compared to my friend's N4 (the camera and screen spoil you, and I can't see feeling the need to upgrade for a few years now that I have a camera I'm satisfied with)
edit: t-mo LTE is -103 inside or out, ATT LTE is -88 with excellent and consistent speed (ping is a bit higher at 240 as prepaid often is, but that's fine for everything I do). And it's certainly not an issue of grip, as I actually get better ATT LTE while holding it than setting the phone down

note 3 low signal issue

Hello,
I'm new to this thread as I've been a HTC user forever.
I just got my first of many N3's last week and it seems that I have very low signal in a lot of places where I typically get strong signal.
For example on my HTC Evo 4G LTE I always get 5 bars and there was rarely any dropped calls at my home and office.
On the N3 I now typically only have 1-3 bars.
I'm sure its NOT a SPRINT network issue but a phone issue. Does any one else experience this issue? Is there a fix to get better signal?
Here is what I did with the sprint and verizon N3.
Sprint:
Purchased at Best Buy and had low signal issue and returned it.
Purchased at Sprint Store had low signal issue and I still have this phone.
Verizon:
Purchased at Verizon store and had low signal issue . They suggested exchanging the SIM card which I did but didnt change the signal strength.
Exchanged it for a different N3 and still had the same issue so I've returned it.

Hello,
I'm new to this thread as I've been a HTC user forever.
I just got my first of many N3's last week and it seems that I have very low signal in a lot of places where I typically get strong signal.
For example on my HTC Evo 4G LTE I always get 5 bars and there was rarely any dropped calls at my home and office.
On the N3 I now typically only have 1-3 bars.
I'm sure its NOT a SPRINT network issue but a phone issue. Does any one else experience this issue? Is there a fix to get better signal?
Here is what I did with the sprint and verizon N3.
Sprint:
Purchased at Best Buy and had low signal issue and returned it.
Purchased at Sprint Store had low signal issue and I still have this phone.

Is it actual signal strength your concerned about or is it bar strength in the notification area? Also you can't compare verizon to sprint signal as a fair comparison as they will be different in different areas. Go into your settings and look at the actual signal strength of both phones. They will be measured in dbm.
i'm concerned with the amount of bars in the notification area which has a direct correlation to the amount of dbm in the settings. the sprint phone fluctuates between -91 dbm and -100 dbm.
I was testing a theory that the lte radio had something to do with it so I just went into settings/mobile network/perferred network mode and switched from "LTE/CDMA" to "CDMA" and the phone rebooted and wham , now i have 5 bars and -69 dbm. Something with the lte is messing with the phone. WTH!!!
That means to get a good signal i have to be in CDMA and only get 3g service. Why is this?
I'm out have no explanation. I have/had that problem too, people at the sprint store tells me its a issue of where the software in the phone isn't recognizing the lte the way it should and that a software fix is coming but no one know when. I was dropping so many calls (89% of them per sprint) on the stock rom I was ready to go back to my note 2, but after flashing a different rom I have only dropped one call since rooting and switching roms .

I don't know if LTE functions on the same frequency as 3g. As a rule from amateur radio, the higher the frequency the transmitter operates on, the shorter distance it travels. 800mhz usually has better penetration of buildings than 3g or 4g if they are on the 1.2ghz+ range. You will need more towers closer together to get better signal overall in the GHz range. Because of cost, I don't think anyone is going to put up more towers in the beginning. Years ago, the guesstimate of putting up a single tower was a million dollars. This is accounting for all costs to go from nothing to a fully functional self standing tower. Costs might be different now but I would say that it's safe to assume that they are putting LTE on existing towers. This is why LTE signal doesn't seem as far reaching as lower frequency technologies. This is as simple of an explanation as I can think of. Until they start widespread rolling out LTE on nextel's 800-900mhz range, and they release phones that take advantage of those bands, you're just going to have to deal with it with what you have as a phone. Spark and ex-nextel LTE transmitters "should" help throughput tremendously once they have the bugs ironed out.
