bad reception on sgn

I am on att wireless
I have noticed that in a low service area i get none at all.
However my wife on her iphone has 1/2 bars and my bro on his atrix also has 1/2 bars.
Anyone else having similar issues?
12/7 Update - More information on what I have attempted
Setting APNS for 4g on ATT
getting correct 4g data plan on account
New Sim cards
Replacement Galaxy Nexus
Different Roms
Stock Restore Rom
restore to default and install nothing
different radio
update to 4.0.1
Once the signal drops to almost unusable levels , the only way to get it back is either reboot the phone or toggle airplane mode. After that the signal returns to a solid 89-93 DBM. After roughly 30-60min it will then drop and I have to toggle it again. All other phones in my location have no problem including my iphone 4s with the exact same sim card.
I am in a decent location for signal. On the nexus reboot its at -89 dbm , my iphone 4s is at -87. The iphone stays that way and the galaxy nexus over time drops to -105 to -111.
Still no conclusion.

I only have problem with Wi-Fi where the reception is considerably weaker than any other device just around it.

Bars mean very little, as devices have their indicators calibrated differently. You should be comparing signals, in dBm for a meaningful comparison.
The acid test, of course, is whether you can make and hold a call, and or send/receive data.

Yeah kind of hard to gauge from bars. Nokia and motorola are known for excellent reception. Samsung not so much. They do seem to be improving on all fronts though, including wifi and gps.
Sent from my samsung gt i9250 which is in the wrong country.

I havent got too in depth with testing but its simple to see there is an issue. Everyone around me can make calls and i cant. Cell standbye taking up battery life as well and has been out of signal for a while

I'm seeing a similar issue.
When I have 2g only selected, I get 2 bars -98 asu 7. When I have it deselected I have no bars and signal is -111 asu 1.

Well ive had similar issues
Today I wiped phone and came back to initially 4/5 bars and download speeds of 4 down 1 up.
Then after about 10 min , right back down to 1/0 bars and 800 kbps down 200 up.
popped off back cover and then pulled sim , reset sim and then reboot. Again it initially came back with 4/5 bars with hsdpa. Again about 10 min later back down to 1/0 bars and a -113 dbm reading,
Then oddly enough i was in the status screen just watching it hover around -113 to -105 , it clicked to edge full 5 bars , then came back to 3G 4 bars and now at -93 dbm.
Does this sound at all normal? I havent changed location more than a few feet through all this. My wifes Iphone seems to be having 0 issues right next to me.

just watched it do it again.
Was at 1 bar went to 0 , got stuck on -113 dbm for about a minute or 2 clicked over to edge-2 -87 dbm then back to hsdpa -93 dbm
:/ i got no clue at this point
there is a video showing some of the issue

Is this at home or a place where you frequently are? If so, I would do one of two things (provided you want to keep the device):
Write an NFC tag that you can tap on your way in (and presumably on on the way out as well) that would switch you over to "2G only" (which it seems gives you a better signal), and back to 3G/3.5G on your way out the door. or...
Either write yourself, or wait for one to be written, a kernel that will throw more power to the radio (at the expense of battery life however- but if you are constantly searching for signal your phone is probably wasting a ton of battery right now anyways)...

ya i am at home.
My wife consistently gets 3 down 1 up on her 4s.
No one else seems to be having issues , perhaps mine is just defective?
this is what happens when i lightly grip phone

Maybe, but I can't think of a way to reliably test whether it is defective or not. My Samsung phones have always had lightly weaker radios than my HTC and Moto phones, and my sister's iPhone, so I will wager that it is just that in the name of battery life the radio is under-powered, which can be changed in the kernel. I was in a similar boat back when I was on T-mobile (right on the edge of service), and luckily someone had posted a custom ROM for the G1 that routed more power to the radios, and gave me just enough to hold a signal and use my wifi for data. Whatever that kernel in that ROM did, it gave me about 10 dbm difference. You might want to throw a request in the development section.
you can also try exchanging the device (if ever unhappy at all you should try to), but I am wondering if it will actually make a difference. Do you know someone with a recent Samsung phone like a SG2 (not LTE/Skyrocket) or maybe one of their Windows phones (I don't know what radios/speeds they use), to see if it gives similar results?

Ya , i was at my brothers house yesterday with no service at all.
My bro had an atrix with 1/2 bars and service.
my wife had an iphone 4 with 1/2 bars and service
and my sister in law had a galaxy s2 with 1/2 bars and service as well.
I had 0 at all.
The odd thing is , every time I reboot my phone it holds on to 4/5 bars at the location im at right now for a good 10 minutes , then flatlines.

what APN are you using? Use the same APN settings as your Sis-in-law's GS2- when my Nexus first came I noticed the APN did not match my Atrix and it would not hold an HSPA+ signal for long; I changed it to match the Atrix and speeds/holding towers has been much better. Try the APN thing.
The GN and GS2 would have the same radio chip (I would imagine), and be set to draw the same amount of power by the kernel. If the APN thing doesn't work then you might want to consider an exchange I guess, maybe it is defective
The fact that it flatlines AFTER 10 minutes (presumably after all the syncing is finished for the various apps and services) is suggestive of a sort of "demand" model- like maybe the device amps up the radio when it knows there will be a lot of need, then scales back when demand is less- or over compensates at first, then under compensates later after some sort of calibration? The ten minute thing sounds odd, but sounds like something software/firmware/kernel-based...
[Keep in mind that there is much speculation contained in that advice, the true test for defective or not would simply be another GN at the same location- as that is unreasonable we'll have to speculate. Also, if your sis-in-law comes back over, check her phone status for her signal strength (not bars but dbm and asu) and see if it matches yours. The bars that you see are a software representation of those two numbers, and can be modified to under represent the actual signal.]

I am using the default cingular 410 apn
ive been reading that if support put a 4g data plan on my phone that it could potentially cause data loss. Is that correct?
also changed to 2g only for now and have 5bars -81 dbm constant.

Not sure I follow, if AT&T made your data plan a 4G data plan, it would interrupt your service?
I think you are asking if changing these APN settings will trigger something at AT&T, and they will "bump" you to a 4G plan- in which case I don't really know, I had to jump onto a "4G" plan when I got my Atrix. I think it would never reach that point though, when you set up the new APNs, that step where you touch the dot to select the HSDPA APN, it would default back to your cingular 410 apn if it were not able to connect (via SIM provisioning or whatever). If unavailable it wouldn't be connected at that rate to begin with.
How old is the data plan you are on (is it prior to the tiered plans)? If you are worried about the connection (APN) not matching the SIM, you could request a new (4G) SIM. Maybe stop in your local store, or call customer service and tell them you are thinking about buying a 4G phone, your friend's brother's uncle' pizza delivery boy's nephew has an unlocked phone you could test speeds with, could they switch out your old SIM for a newer 4G one to see if it will be worth your while at your house, then just pop in that new SIM, change the APN and away you go? (Or to be even less complicated take your old phone in with your old SIM, and just ask for a new SIM card, that yours isn't working right, and it should be a new 4G (not LTE) card...
Well, at least the phone is usable on the 2G band for you, and will save a lot of battery. Meanwhile we'll try to get you connected to an HSPA+ tower.

thanks for all the help really appreciate it.
Anyways a few things have happened since I last posted.
I had an iphone for the last 3 years. I went into ATT last week and got a normal 4g sim card in advance. Today I called my buddy who is a manager at a corporate store and he checked my account. Found that the lady had the wrong data on it. He ended up setting the sim to the 4g plan etc (which is unlimited)
I was able to add the ATT HSDPA apn and successfully connected to it. Prior to this I actually installed modaco's rom and restored everything.
At this point I am getting consistently 3 bars in my house (which is more than my wifes iphone 4s) on 4g.
Seems to be working much better now. The only other issue that remains is when I turn on WIFI. If i turn it on the cell reception goes to 1 bar or sometimes 0. I dont have the exact dbm values right now unfortunately. Calls and text still seem to go through however. Is it possible the wifi is drawing power designated for the radio?
Thanks again !

Awesome, glad it worked out.
And possibly yes, depending on how the kernel relegates power wifi could "commandeer" a little from the cell radio, and reduce the dbm just enough to reflect in the "bars" algorithm.

perhaps a new radio will eventually come out that I can test.
either way seems to be at least in service now , signal definitely drops when i hold the phone but as long as I can make calls it should be fine.

in the meantime i'll suggest using the open signal widget https://market.android.com/details?id=com.staircase3.opensignal&hl=en
which will tell you the real reception in the phone, and see what you are getting behind those bars
don't expect to make a good call when the signal drops to -90 dbm and above
and if you have multiple phones like i do, then you can compare if other phone in the same spot, connected to the same tower, is having higher or lower dbm than SGN
for example my Nexus S had worse reception than my Milestone XT720.... go figure

Thanks I will try it out,
Overall i dont think the issue is fixed at all now. Went to bad and signal dropped all the way again. Stuck at -111 dbm. I held the phone i saw it switch to edge 5 bars and then click over to H 4 bars.
I really believe its some kind of software thing. If I cycle airplane mode on / off I get 4 bars (unknown dbm but its working) of 4g service. I know the service is here and working as my wifes iphone is fine but something is causing it to not hold the signal and eventually drop and not recover.
Makes no sense
Downloaded the app ,
Was at 42% signal strengh, I noticed when I picked up phone and lightly held it , it dropped right on down to 5% and got stuck there. This wasnt death gripping it either , barely holding it. Does anyone else have this issue or is it just mine? I know all cell phones have this issue but this seems excessive , worse than my iphone 4 ever was. I then cycled airplane mode again and signal strength went right up to 65% again -89 dbm

[Q] LG G3 Three UK Signal Dropping

Hi all,
Is anyone else experiencing terrible signal on Three UK? My dad just got his G3 and compared to his Nokia 925 signal on Three is atrocious, and seems to drop in an out constantly?
Anyone else experiencing the same?

Not on 3 but I'm on ee (T-Mobile) and I have some prob outs at times that I found has been bit strange but most the time I have great signal.

I am on Three, had no signal concerns at all except in areas of weak signal. The phone doesn't seem great at maintaining a connection when signal is weak, whereas other phones might stay with 1 bar this drops to none, but otherwise signal is as good as can be expected.

No problems here
Sent from my LG-F400L

I have had this problem on 3 UK. I found that going into network settings and choosing the network mode without LTE stopped it from happening! Any idea why this may be anyone? Do we have defective units?
Matt

The g3 is just very slow at finding signal when its lost signal - what is happening is you are losing signal (even if just a split second), any other phone would probably instantly reconnect but the G3 seems slow - this is all software based (well, radio firmware) and can be fixed (and word on the street is that it will be fixed in the next, August, release).

Thanks for the info, I won't be sending this off any time soon then! Also thanks for your unroot and chromecast volume fix guides they have been very helpful.

Wouldn't enabling fast dormancy help to find the signal quicker if it loses it?

I have also seem a connection problem on three in the UK. I figured switching off lte stopped it happening so much but then again I get 4G free and three tell me I have good signal strength for it so it seems silly to turn it off. Having said that I haven't seen it pop up once yet. Anybody tell me what the signal icons are on the G3, I have only had H so far? Cheers

I haven't seen the 4g logo yet either as I live away from any LTE areas, I've seen H and H+, 4g will show up as either LTE or a 4g symbol so I assume that your phone isn't connected to LTE/4g if you haven't seen either of those

Yep that's what I figured. Tweeted three cs but didn't seem to get much help. Thought maybe it's because I'm a SIM only customer. But I have checked there website and to all intents I should be connecting. 4G is good on my area. Not sure what else to try?

Enable fast dormancy for the 3 network. 4G works great on 3 in cities where it is supported.

How to enable fast dormancy? Website gives my area a good signal. I don't even get H+ which I did with my galaxy s3.

Have you tried the options when you enter 3845#*855# into the phone ? I had to use this as I was not getting LTE. See here for more info http://forum.xda-developers.com/lg-g3/general/mod-root-activate-lte-g3-t2819387

The option its already in my network settings menu and switched on. Are these different? Just can't put my finger on it.

I am having the same issue with my LG G3 on Three, the signal is much worse than my galaxy S3. Drops out randomly in my house and then takes ages to get a signal again.
Wondering whether to send it back our not as a phone with bad reception is kind of pointless! Anything perhaps fixable with a new firmware for the radio?

Yep exact same issues. Hoping it's not the phone (bought it myself not from three) really like it and Up to now three was great ? gutted.

It seems the phone either had really good or really bad reception. In poor area's it's quite flaky and can drop out easily when moving between rooms or even how you hold it.
If the reception is good you can get some great speeds on 4G though. Hoping they fix the issues with low signal strength soon as it's quite annoying.

Had a text from three saying they were going to fix my issue within the next seven days. Not picked up a 4g signal at all yet. So watch this space.

I also had problems with signal. I got a replacement SIM & that seems to have improved matters.

4G not working(UK)

I was wondering why my phone always displayed the 3G logo next to signal bar so decided to investigate further. Despite living in the centre of town the 4G around here is quite patchy so I put an identical "Three(3UK)" 4G sim in my old Moto G 4G phone and went outside to compare...sure enough, the Moto G was showing 4G while the P8000 showed 3G. As far as I know I have never seen 4G in the display. The phone will be going back if I can't get 4G!
Anyone else experienced this or am I the odd one out?
4G is selected under preferred network type.

Have you tried Editting the APN settings to that for Three?
Sent from my Nexus 4 using XDA Free mobile app

Go to dial pad and type:
*#*#4636#*#* that should take you to phone info. then on nework mode choose LTE only and see if it works...

APN seems fine, thanks for that hashcode @ferreinf - I will try that when I'm definitely in a 4g area near my flat

My brother has just got one and is having exactly the same issue on Three. Any joy?

I drove to a 4g area nearby today and force enabled LTE only as described(you can also d/l MTK engineering app from playstore to do this) - I did manage to get the 4g symbol above the signal bars but a speedtest didn't really produce what you might expect from a 4g connection...the symbol did change back by itself to H about a minute later so I'm not quite sure what's going on here....I might have an old Vodafone PAYG sim somewhere so my next move might be to try it instead. Haven't got access to EE or O2/giffgaff cards to test. APN settings seem to be correct and 3g data does work quite well so it's interesting that your bro has the same issues, where did he buy his phone and what colour is it(does his have the blue notification led in home button?)

I think it might have been geekbuying, it only came today. Black one with blue LED. I got him to try switching to LTE only and he said he got a 4g signal but lost ability to make calls. I'm also on 3 but with a Honor 6 and I'm due to see him tomorrow so I'll have a tinker myself and see how his signal is compared to mine in the same location.

That will indeed be a good test, I was out again in another location tonight and noticed the 4g come on by itself so perhaps that's a good sign - I'll have to test the calls function when on 4g tomorrow but it should automatically revert to 3g for that surely. I am using the flyme rom by the way...my area is supposed to have 4g according to the coverage checker but it's bloody useless around here!
That Honor 6 better be good for $300 though you probably paid more at the time(did you get single or dual sim?),
I actually bought the P8000 for my wife but she finds it too heavy and the screen too big so I'm stuck with the big gold brick - at least the battery life is pretty good!

Tested the 4g again and it seems to be working better now that I forced it to LTE through the engineering menu and when you make a call it reverts to 3g then cycles back to H then 4g when you end call. Didn't test d/l speed as I had my payg card in and running a 4g speedtest burns quite a lot of data!
So how do you rate your Honor 6 against your bros phone?

4g just popped up on mine, got 25.3 down and 2.2 up. Not sure if that's good or bad to he honest.
Sent from my Elephone P8000 using XDA Free mobile app

That's pretty good I'd say, I would be happy with that! I flashed the stock ROM back today and forced phone to LTE and your bro is right about the calls not working as the phone doesn't revert to 3g for voice automatically so I might have to go back to flyme...hope cm ROM is here soon and that it works well!

Tried again today on stock rom not forced to 4G and the phone did pick up 4g automatically as I was driving around, calls worked too so it seems that problem has magically fixed itself as it wasn't showing 4g at all the first week I had it! Still getting the annoying random wifi hangs and camera crashes when trying to use with other apps(waze in my case).

there's an firmware update adressing this issue, dated august 15th. it should fix this.

Sorry, not been back to this thread since contributing before.
My brother is still complaining about internet speeds. When I sat with him I was getting H+ but his phone was just showing 3G. Tried to force to 4G only but that resulted in no signal (we were in a weak 4G area). So my main concern at the mo is that he might not be getting H+ and is only either getting standard 3G.
It's difficult to debug from afar, but I did all the usual engineering menu stuff when I was with him and none of that seemed to help. I'm seeing him again on Saturday and we'll both be in a 4G area so I'll at least be able to do some more comparisons...
Regarding my Honor, it's a lovely phone. I paid about £200 for the single SIM European version of it back in January. I had a Lenovo A830 prior to that so I'm a big Chinaphone fan, but didn't want anything bigger than 5" which is what made me go for the Honor. The P8000 seems very nice too though!
---------- Post added at 08:21 PM ---------- Previous post was at 07:50 PM ----------
I remember on my A830 having to flash a different modem / radio image to get the correct bands and I notice a similar issue with some import OPOs detailed here forums.oneplus.net/threads/modem-hack-for-chinese-opo-to-enable-3g.46696 - I suspect a similar issue might be at play here.
Might flash the FlyMe ROM for him at the weekend seeing as people have had success with that...

Hi,
I have 4G issue too but have yet to see 4G display once and I"m in a strong signal area.
I have configured my APN for giffgaff, data is enabled, 4g is "preferred" in options and LTE is forced in Eng menu as above *#*#4636#*#*
But still no 4g from my sim which is working as tried in another phone any ideas please?
what does the 3g with a smaller 3g behind it mean?

signal issue

In my apartment I have been getting about 1 or 2 bars with TMobile. I call TMobile and end up getting a signal booster. The problem is when I got the signal booster hooked up it's saying it's getting a full 5 bars of lte in the same spot my phone is only getting 2 at most. So the booster won't actually boost because it says the signal is good, but my phone basically has dial up speeds. The way Thia looks is it's a problem with my phone but I don't understand what it could be. I'm running OmniRom with the current recommended firmware. Anybody got any idea on how I could remedy this situation? I already looked up the signal boosters supported bands and they're just 2/4/12 which is all supported by the mix 2. I don't have WiFi so this is basically my only option to watch anything online

Try a new sim card?

In my apartment I have been getting about 1 or 2 bars with TMobile. I call TMobile and end up getting a signal booster. The problem is when I got the signal booster hooked up it's saying it's getting a full 5 bars of lte in the same spot my phone is only getting 2 at most. So the booster won't actually boost because it says the signal is good, but my phone basically has dial up speeds. The way Thia looks is it's a problem with my phone but I don't understand what it could be. I'm running OmniRom with the current recommended firmware.

Weak antenna?

Seeing 4 bars of LTE signal strength on my phone is like seeing a unicorn.
I live in Upstate NY and I have the A705MN phone.
I have tried three different sim cards, all of them of course GSM compatible. The result is exactly the same among all three. I typically get 1 or 2 bars LTE.
My previous phones under the same carrier and same sim card were typically 4-5 bars. (The Wifi strength, BTW, is equal to what I've seen from my other phones.)
What can I do to improve the signal strength?
I've seen posts by those with S10's where they do something to disable specific bands. But I'm not sure how to do that on the A70 phone. I've tried the specific codes that were mentioned in threads for the S10, but those codes do not work on the A70.
Please help. As much as I like the Samsung otherwise, this factor might be the reason I return the phone.

Yes same problem here

Try LTE only settings in settings>connections.

Thank you for the screenshots.
I edited the access point that I'm using and changed it to LTE. But then when I go to select network mode, I cannot chose LTE Only. That option does not show up. I have tried rebooting after editing and selecting the Access Point, and I still do not see that option.
I have tried using apps such as 4g Network Only and have switched to LTE only, but that change does not seem to make a difference or the network goes down altogether.
Any suggestions?

There was a post in the forum for using settings editor app to enable LTE only option. It will enable this option for both sims.

I haven't been able to do this or find what it is you're referring to. I've tried adding a few values through Settings editor apps. Values such as "hw_networkmode_preference" etc.
Doesn't work.
But besides, why would setting the connection to LTE only fix this problem? I don't see how this is not a herring.
Most of the times I am see 2 bars of strength. Every now and then I get 3 bars, and more frequently than that I get only 1 bar. 4 bars is quite rare.
The real problem with this antenna is that if I step inside a supermarket or bathroom then my connection is gone. If I'm traveling around the state of NY, in more remote areas, I'm sure I will not have a chance of any connection.
I would LOVE this phone if it had a better antenna. I can deal with the subpar fingerprint reader. Just give me a strong antenna like all of my previous phones and then I'd be a happy camper!
I decided not to return the phone so I am stuck with this phone.

Setting the band to lte only would help in better reception even at low signal strength. One thing I had noticed in lte band is its consistency in connection speeds and call quality even with low signal. I think this is because of the high bandwidth of the lte signals. But I'm not an expert in it. Try changing the band to lte only. It should work better.

But I'm trying to get better signal, rather than better reception with low signal.
There's got to be something wrong with my phone. It blacks out if I step inside a bathroom in a building and such and it's very rarely at 4 bars.

A thing I noticed. If I go and select 2g/3g only (switch off 4g lte) my signal reception instantly switches to full (4 bars) Usually I get around 2 bars with LTE active.
The strange part is that even with lte off I can still receive an lte 4g signal when outside..this is perfect for me as it means i have a really strong signal (reception) indoors but still have the benefit of 4G outside. I don't quite understand it tbh. I mean i have switched to "2g/3g only" yet i still see 4G pop up in the status bar on my commute, and it definitely receiving 4G speeds. I'm not sure if it's a bug or not but I kinda like it.

That's a terrific idea. Thank you for bringing that up.
I am implementing your suggesteion and it's nice to see 3-4 bars of strength again.
I don't need the fastest data connection. I just need a strong or secure basic data connection, since most of the time I'm not doing anything data intensive with my phone anyway when I"m away from a wifi connection.
But I'm not sure if my phone hops up to LTE at anytime.. I wish had the same "bug" that you do. I just started testing with your settings so I'll see if I can get it so that 3g is the preferred and basic network and 4g is the optional...

After another day, I'm back to LTE/3g/2g auto.
The general reception even for 3g or 2g is lower overall than what I saw from every other phone I have used. So in areas where I can expect to have a relatively low signal I get a particularly low signal for all bands, 4g, 3g, and 2g. That being the case, there's no practical difference if I cap my connection or not.
Samsung better warranty this phone. Does anyone know who I should call?

Since I bought my phone through an Ebay seller and the phone is West Carribean stock, not USA stock, which is where I am, I have no warranty on this phone.
