Poor reception on S3 somewhat fixed

So let me start off by saying I have pretty bad reception at home with 4g.
I had an iphone 4 with a 3g range extender before I got the S3 and it worked great.
Found a free app called phone info
Went in under device information, selected cdma auto (PRL). I restarted my phone.
I now have 5 bars and perfect clarity.

You get 4g in CDMA auto (PRL) mode?

I am usually about 2 bars where I am. Making this switch didn't change my number of bars or dbm. I'm glad it worked for you however.
I expect by making this change, you are basically downgrading to 3G until you set it back.

If you have a network extender for 3G then that's the fix. Not turning on thst option.

I am downgrading to 3G and my range extender only works for 3G not 4g. Verizon claims to not have a 4g extender yet.

Not exactly. The phone will stay in 4g with one bar even if 5 bars of 3G is available. So forcing the phone to switch to 3G is the only way I got the call quality I needed to make calls in my house

What's the make and model of this range extender?

Unstable 3G performance
So I've had my S3 for a little over a month and have noticed the poor call reception that people have mentioned,especially in my office building. My old droid 2 global never had a problem, but when I receive calls on the S3 i have to walk to A window down the hall to keep the call from dropping. In an attempt to stay on the more stable 3G coverage in the area I installed phone tools and forced 3G. The problem I have now is that when I'm out of the office or house and not on wifi, I pull the phone put of my pocket to check something and there is no data connection at all now. Even if I open my browser and try to force a connection I get nothing. If I set the radio back to include LTE I have a reliable data connection everywhere but my calls are still poor.
Am i missing something when setting the phone to be 3G only? Thanks.

Ok i tried that phone info program and set it tup cdma auto or whatever, and no improvement. How do i get back to stock? I tried setting to lte/cdma/evdo but it does not stick. I tried uninstalling the program and the phone would stick to 3g. Help!

Just download the phone info app and switch it back to lte/CDMA/evdo when you switch it turn off the radio at the bottom and wait for a couple secs then turn it back on

I wish Verizon and Samsung would just get together and try and resolve why their phones don't work well on Verizon's network. I figured they'd learn what they did wrong with the Nexus - pretty upset they never resolved it with the S3. I'm hoping the DNA/DLX from HTC doesn't have this issue. I liked the Samsung S3 in just about every way but the reception is wretched compared to Motorola phones.

yea I agree...the reception is awful. Literally can't use the phone for business. Everything else about it is awesome though

It has to do more with your location I think..I work in the tri-county are of Detroit and my reception is excellent. Had a Cappy on ATT before my GS3 on Verizon and could not even get a signal in our office building..now on Verizon I'm at least 4 bars and full strength pretty much everywhere else..

It seems to have to do with the technology of the Verizon towers in your area. In LA with a motorola phone I lock on no problem and get great reception. With the S3 you'll switch from 4 bars - drop the call and switch back to 4 bars even when stationary. Motorolas don't have that issue with Verizon's network. I know several people with the S3 including people in CT and TX - all having the same issue on Verizon's network.

LTE not working?! Manual Programming codez (updated)11-7

I got my Nexus 5 yesterday and finally got it working. I live right next to a LTE tower and I can't seem to get LTE.
1. Checked PRL
2 Checked Sim
3 Checked Profile
4. Called sprint
5. Checked network settings.
When i put the phone in airplane mode, and back off. It jumps to LTE for 2 seconds then 3g
Anyone having these issues ???

*manual re-fresh*
*#*#72786#*#*
after that, phone will reboot and "re-fresh network"
Also, my phone wen't into global mode, which you will need to change that back to LTE mode.
- Still isn't fixed ...
will report back ..

Manual Programming Code
*#*#675#*#*
edit: MDN = phone number
MSID: split

UPDATE
doing *#*#4636#*#* and selecting LTE only does indeed make LTE work both visually and functionally, with a loss of voice of course, but as soon as you go back to LTE/CDMA auto it'll require a reboot to take effect and LTE is once again not working.
(from sprint forums) - confirmed

I'm having these issues with Sprint as well. Thanks for your updates. I'll let you know if I learn anything.

You're Welcome,
Yes, this is very aggravating. My friends have LTE sprint phones and get LTE standing right next to me.
There is something wrong here! :/

On phone with sprint now, I hope they have an update.

Here is how I fixed it for myself on Sprint.
Settings > More > Mobile Networks > Network Mode
Change Network Mode from Global to LTE.
It will still connect to Evdo, ehrpd and Lte and switches between them as needed.
Luckily I haven't got hit with 1x since trying this out. My area has maybe one or two spots where I'd get 1x instead of ehrpd.
Settings hold after a reboot. I was driving to work today with my phone playing my music and it seemlessly switched between 3g and lte on it's own.

I guess so because I was having that same initial problem you were where LTE would connect for a few seconds then when I tried to do anything with data it stalled out and went to 3g.

Mine does that too.
BUT, nothing in the settings has been able to fix this.

How long since you activated? Mine would not connect to lte at all until last night... about 30 hours after activation.
Now it connects fine. I tried everything including flashing the modems posted in dev, swapping sims, trying every different network config and nothing worked except lte only mode which then kills 3g and voice.

I too am having the exact same problem as the OP. I can change the setting from Global to LTE and the phone will connect to LTE for a few seconds before switching back to 3g.
I am coming from the Note 3 on Sprint that got great LTE here at home, about 16mb down and 4mb up but I am hoping this gets resolved quick.

I'm on T-Mobile and it favors sticking on HSPA+ instead of LTE. If LTE gets down to one bar, the phone decides it's time to switch back. Compare this behavior to my Nexus 4 and it would stick on LTE come hell or high water. I would stay on LTE while in the office and this phone refuses to even get on LTE in the office. I don't get it.
Some have suggested this is a "power saving" feature, but I call BS on this because my Nexus 4 wasn't even intended to have its LTE radio used and LTE really didn't impact my battery. It felt like it lasted the same as it did before I enabled LTE on it.

Possible Sprint Fix
Customer: Is the SIM device specific? I reused the one from my Note 3. I have seen other information that the SIM's for the Nexus 5 are device specific.
Mitchell C.: Yes, you can get a SIM for the Nexus from a nearest Sprint store. I can fix an appointment for you.
Customer: so they are device specific?
Mitchell C.: Yes, they are.
Mitchell C.: We've come across a lot of these issues today.
Customer: SO just to be clear, I need to ask for a SIM for the Nexus 5?
Mitchell C.: Absolutely.
Customer: ok
Customer: that should correct my connectivity problem?
Mitchell C.: Yes, every service will work fine after you get it.

Well, I got my sim card from a sprint store 2 days ago and I am still having issues. I have been emailing sprint care but no luck.
I hope they fix this soon! Maybe they gave me the wrong SIM? Idk

Doubtful Mitchell knows what he is talking about. People have used HTC One SIMS and GS4 sims and have LTE. But, today is the big day the Sprint phones go on sale. Will be interesting to see if any of those people have the issue.

Still stuck on 3G after activating around 72 hours ago.
To follow up on the Nexus 5's "special" SIM card. I'm also skeptical about this. I'm using a SIM from a GS4 (part #: SIMGLW206R) which is the same SIM mentioned in this post about activating the Nexus 5 on Sprint: http://qbking77.com/google-nexus-5/activate-nexus-5-sprint/.
However, I called a nearby Sprint store to ask if they had any SIM cards available. They said yes but when I mentioned the Nexus 5 the representative seemed to think there was some additional procedure for coupling the phone and the SIM. I don't know any more about this. Could be misinformation of course.

[Q] Stuck on EDGE or GPRS

When I'm on data, my phone is stuck on EDGE or GPRS when it should go up to 3G or H+. I've tried restarting my phone, turning wifi on and off, turning data on and off and made sure my settings looked okay. Any help is appreciated!
Cataclysm 11/26, Franco r14, dalvik patch. And if it's relevant, I'm on Rogers wireless.

I'm not sure but doesn't Rogers use global frequency in which case you need the 821 model?

I've definitely had 3G and H+ on my N5 (abbreviations much?), but it just seems very inconsistent. It'll go from H+ to 3G, back to H+, then cut out completely, then sit on E or G for a while. Just trying to pinpoint the issue because it's getting annoying haha. Perhaps it's the frequency that's screwing it up but that's definitely not my area of expertise. I do have the D820 model if that's helpful.

I'm having exactly the same problem with Fido right now, I tried pretty much everything including
- flashing back the factory image
- tried every modems from the xda thread in the Nexus 5 Android Development section (currently my phone is on the D821 modem but it didn't change anything)
- changing my apn (but it was obvious that this was not the problem since the phone had a edge connection.
I'm really about to call Fido...
Still, I'm kinda glad to see that i'm not alone.

maybe that the data service in your personal area?

Well going back and forth between 3G and H is normal. It picks up H/H+ when receiving/transmitting and goes to 3G when idle to save power.

I called Fido, the technical support told me that they had something that was blocking me from 3G (but he didn't tell me what it was, he just told me that something was blocking me...) I had my beloved H+ back for maybe a whole minute and then it just switched back to Edge network.
All I wanted to know was if many customers have reported the problem or if I were alone...
Maybe if I'm lucky my phone will get back its 3G soon just like you.

I'm still having the issue today.
I called back Fido and they tried different things like desactiving/activing back my line, "updating my line" and more without any success.
Then I called google and told them the problem. They will change my Nexus 5 for a brand new but at the same time I feel like it is a software issue and not an hardward one... Well, we'll see, I never had a problem like that with any other phone before and the Nexus 5 never had any problem with 3G before yesterday.
I haven't tried everything yet, maybe you could try :
If you are in a LTE area, can the Nexus 5 connect itself to this network? Nearest LTE area from where I live is like 40 minutes away, bit too far just for a test.
Try with a sim card from another company like Telus or Bell, is the phone connecting to the 3G network? (I though about this while calling Google..)
Well, hope that the next phone will be ok.
Here are the few pictures just to show you a proof that even when I request a webpage, the phone will stays on 2g only.

Thanks for the update mark1s. Definitely let me know if a new phone fixes anything, although I'm also thinking it's a software problem.
The problem could just be that there happens to be patches of low coverage in the areas we're testing this out, which seems unlikely in big cities. But testing at work seems to have this problem, but testing this at home I pick up 3G and H+ just fine. Odd..

[Q] Nexus 5 only connects to LTE on T-Mobile

I did some searching around and found a couple of pages with ideas but they have not worked so far. Here's the deal, my son's said his Nexus 5 was getting pretty bad reception so I took a look at it. After some toggling of the network settings I discovered that it will only connect to LTE, not to HSPA(+) or Edge. Where we are, we have somewhat weak LTE (2 of the three towers have been "modernized" with LTE and band 2 HSPA+, one has not and it's slightly closer to us). We have a Cell-Fi repeater so we get strong HSPA+ signal in our house. His sim works fine in a Nexus 4 with the hybrid radio getting Edge, HSPA+ and LTE. My nano sim with adapter that works fine in the Nexus 4 exhibits the same problems in the Nexus 5. I tried formatting the cache from the stock recovery menu and am now looking to do a factory reset since I never did oem unlock this phone so I can't just flash a radio to test.
My gut tells me it's hardware so I have my son rebuilding his phone environment on the Nexus 4 so that we can do a factory reset to see if that helps and I'll unlock it at that point. If it doesn't fix it, I've already started the conversation with the play store. My question is, anyone else seen anything like this? Anything else I should try out?

if lte is in your area, and not a perfect signal, itll still choose to connect to lte by default. if you lose your lte connection, then itll connect to H or 3G, and so on. if you do not want it to connect to lte, go to the phones main settings, mobile networks, then change the preferred network type from lte to 3G. or you can dial *#*#4636#*#*, chose phone info, then change the network type to wcdma preferred.

Thanks for the reply, I understand all that. I don't know if I asked clearly enough or not but the problem we are seeing here is that this particular phone can only connect to LTE which is weak inside my house. So, when it tries to switch over, it just won't connect. I also tried to make a call which will switch to HSPA+ and that too fails. Going to the info menu and selecting WCDMA preferred nets me a phone that won't connect, selecting GSM results in the same. LTE only or GSM/LTE works only if it picks up an LTE signal. Ditto for selecting 2G, 3G or LTE preferred in the Mobile Networks menu. I've also reset the APN's, confirmed that the settings match my MotoX, etc and still no joy.
Just looking for ideas that someone might have that I can try before blowing away all my son's data on a factory reset or, if that fails, hardware replacement.

ok, i understand now. i didnt know that it wasnt connecting to h or 3G when it should. to me it sounds like a device ready to get an rma. i mean there is a hardware mod that could possibly fix it, but its not worth the trouble. if you can get an rma, get an rma.

Yea, according to the nice person I spoke to at the play store, I should indeed qualify for an RMA and I should find out in the next day or so. I purchased the phone new in box from someone and they were able to find the phone and they are now attributing the phone to me.
I am curious about the hardware mod though. Is this just for Edge/HSPA or is it for signal in general? If it's signal in general then I'm not sure I'd want to try it since this phone used to work just fine.

Nexus 5 LTE weak signal reception.

Dear experts.
i have finally decided to share my ''unlucky epxerience'' with you.
i have got a serious problem which i have been fighting with since the first day i purchased my phone.
i have a white nexus 5 32 Gb version,D821 model.
and i'm from morocco,which means 4G will work for me because my phone is the indian version not the american version that doesn't support 4G in the rest of the world.
so,my problem is like that: when i first bought this phone i got stuck in ''emergency calls only'' for one week like every nexus 5 users did due to this known problem about the phone.
and after many reboots,clearing cashe,and searching manually for network,i got the signal again.
i never tried to switch to LTE mode,becuz i thought it would charge me a lot of data.
but,after a while i decided on and switched to LTE and got stuck again in emergency calls only !!!
i tried many things like contacting my carrier,searching manually,inserting another Sim card,force switching to LTe by dialing *#*#4636#*#*
but to no avail.
i decided to go to the nearest 4G tower and make sure if the problem had to do with 4G coverage or my phone's antenna.
then,i finally saw the LTE logo with full bar.
to sum up,now,i can't use 4G unless i'm near a 4G tower.
moreover,sometimes my phone loses signal even when i'm using only 3G which leads me to switch to 2G to catch the signal or reboot my phone many times and manually search for network.
i don't know if the problem has to do with the antenna or the bands of my phone.
and since i know nothing about flashing drivers or enabling bands.
i don't wana risk and end up by disabling any obviously enabled band.
i never took my phone to repair,because Lg service isn't available in my erea,plus i don't wanna give my phone to a dumb that would make it worse,because i fix my phone all by myself.
please help me solve this problem.
if anyone has any clue like repairing my 4G with octobox or trying to fix the antenna please.

Edit : yesterday,i removed the back cover of my nexus 5 and found out that it's actually a D820
that's weird because rebooting the phone to bootloader it says D821 (H)
and i was wondering what does that (H) revers to ?
but the thing that confuses me is if it's actually a D820 why does it catches LTE near a 4G tower?
does that mean the bands are already enabled ?
do i still need to enable any other band to make it work properly ?
thank you so much in advance and waiting to hearing from you soon.
