hello guys
i bought my lg g3 (d855 32gb ) 10 days ago. phone worked fine for first week after that its signals started to drop . I used to get 2-4 signal bars of 4G on the ground floor but now on the ground floor either my phone loses signal completely or get 1-4 bars of 2G and signal is fluctuating alot .I compared my device signal with my brothers 3 year old xperia arcs and my g3 signal strength was always 10 - 20 dbm less than my brothers arc s . When ever i go from first floor to ground floor my g3 loses signal and it takes time to get signal back but it fluctuates alot. I dont know wheather its a software issue or hardware issue. A little help will be really appreciated. thanks in advance.

EVO Brethren,
My signal will bounce from 4 bars to NONE and back to 2 then 4. Apparently it does so during calls too because I can't talk more than a few minutes before it'll drop. At work it'll bounce from 2 to NONE all day which just drains my battery like mad.
I'm using the latest radio and have tried reflashing it. I'm pretty sure this has always happened even on the older radio. Is Sprint service really this terrible or is there something I can do to fix this?
I can't help you with your problem, other than to say that it won't happen when you are within good service coverage.
I have the same hyperactive signal bar inside my home where I get terrible service (3 bars max when the moon is just right). The signal with jump to full bars and then drop to one or zero.
I would assume that it's the radio trying to boost your signal by cranking up the power. It probably works for a second before the phone realizes that to maintain more than 3 bars of service, the radio would require a nuclear reactor to power it, and therefore promptly lowers the power to the radio.
I have no idea, thats just my guess. When I'm in great coverage it has no problem holding bars, bad coverage - crazy dancing routine.
I am not one who has run into the LOS just yet, and here's to hoping I don't.
However... I do have terrible signal pretty much inside anywhere. Outside or in the car I have had pretty decent signal everywhere I have gone. However whenever I am inside pretty much anywhere I get 0-1 bar at best, and often even roaming does not function.
Is anyone else experiencing anything like this?
Is there any development for fixes for improved signal/antenna? Is this even possible?
Thanks a lot for everyones time.
That sounds pretty bad. I did notice that the Epic 4G Touch's signal strength is often 1-2 bars lower than the Evo and Evo 3D. This does include inside locations, so I've resorted to using Google Voice for texting and Groove IP for phone calls when I have Wi-fi.
Maybe take the phone to a store that has the same phone in stock and compare signal strength?
I just got this phone a few days ago switched from Verizon and this thing is always roaming im outside at a dog park and its roaming this cant be sprints service im guessing horrible signal strength.

Bars are not a comparison of signal strength between phones you have to look at dbs

I just got the phone a couple days ago and I was having the same issues inside my house. I could not even get the xda app to load. I took out the default proxies and it has helped, at least it feels like that to me.

This is a well known issue that's been talked about since its release. Hopefully it will be on the list of things they try and fix in they first OTA update along with LOS and Android OS
Not saying this applies to everyone, but I figured out why the particular E4GT I was testing had such jumpy signal levels. I was doing side-by-side comparisons with an Optimus S using menu->settings->about phone->status.
It appears the E4GT has very little granularity with signal strength reporting. It only goes by increments of 5 dBm, whereas the Optimus reports signal levels at a granularity of 1 dBm.
For E4GT, -106 dBm = 0 bar, -101 dBm = 1 bar, -96 dBm = 2 bar, -91 dBm = 3 bar - 86 dBm = 4 bar, -81 dBm = 5 bar, and -76 dBm = 6 bar.
Problem in my main test area is the signal is somewhere between -93 dBm and -98 dBm according to the Optimus S. Whereas the Optimus S can react to small changes in dBm with equally small changes in reported signal strength and "# bars", the E4GT tends to like jumping from -91 dBm to - 101 dBm and back. It only reports certain discrete levels and it appears to be rounding up and down (based on side-by-side signal comparison to Optimus S) They both go up and down at roughly the same time, but Optimus S does it smoothly over time. E4GT just does the signal change reporting very abruptly with 5-10 dBm jumps.
Second thing I noticed is hand and phone positioning really affect the signal strength. The antennae/transmitter appear to be at the bottom hump on the phone. If I place my hands over that area holding the phone normally I can go from 3 bars (-86 dBm) down to 0 bars (-106 dBm). Data starts getting very iffy at -106 dBm but still kind of works, just real slow. If I hold the phone in the middle or near the top, I almost always get the same or better signal. I also found the phone gets the best signal when it is held flat, rather than perpendicular to the ground. In fact the best signal I get is when I'm not holding the phone at all, and instead lay it flat on the table.
Again, I'm not saying every phone behaves this way nor am I saying this explains everyones' signal issues. I'm just relaying my experiences.
BTW the signal levels when laid flat on a table side-by-side to the Optimus S is very comparable, almost the same (minus the lack of granularity). However when I'm holding both phones, the E4GT has generally 5 dBm worse signal, sometimes 10 dBm if I'm holding normally and covering the bottom of the phone.
That is very interesting sfhub.
I really hope the OTA has some bearing on these issues. I really wish it would come out sooner than later. I have another week or so to decide to keep this phone or not and really don't know regardless of if an OTA is released whether i will keep it or not.
There is a lot to like and a lot to drive you crazy about this phone.
I am using 4.0.2 stock version and wifi signals are pretty weak. Is there any tweak or some settings i can flash to get better wifi reception . . .
I am having the same problem. Out of 5 phones in the hotel lobby (HTC Desire, HTC Wildfire, Iphone 4 and Nokia N97) my Galaxy Nexus had the weakest signal, and sometime even lost the wlan.
I notice wifi signal drop when i cover the top part of my nexus with my hand
tested in speedtest, it also shows slightly lower signal bars, are you using a wireless N router?
Try flashing different basebands to see if signal improves. Also, I recommend franco's milestone 2 kernel since it has a setting to amplify your wi-fi signal (at the expense of lower battery life)
I don't have this problem in fact my wifi speeds are insane

The WLAN antenna is to the middle right of the phone when you look at the display in portait mode.
If I make sure that area is not covered by my hands the reception is quite ok with my Nexus.

I took an old router and made it a repeater bridge, problem solved.

I find the radio on the phone is quite weak to begin with. iPhone lasts much longer out of town where I live.
Hello,
I normally get 3/4 or 4/4 bar of signal inside my apartment. I have had LTE for a few months.
However, last few days, I get no signal inside my apartment. If I just walk out front to the sidewalk, I would get the signal back.
What gives?
I have not dropped my phone or any such thing. Firmware is all up to date.
Hi there!
Several weeks ago and after a fall to the floor, my loved D855 is unable to make standard phone calls. So, it has LTE signal but when you are about to call (or receive a call) it tries to switch to GSM/UMTS network (as my phone company does'nt offer VoLTE) and is in this moment when signal is dropped (and call is not even started).
After a bit of investigation, resetting it, rooting it, flashing LineageOS (BTW i Love it)... behavior continues and I've realized that phone has a general signal attenuation (regarding only to mobile networks), because wifi signal is OK. I can only make standard calls when I am 100 meter LOS a base station...
I spent about 30$ in antenna replacements (PCB Antenna, Upper antenna, Lower antenna ) and also I bought the coaxial cable that goes from upper PCB to lower): Without success
So, I can use it only as a "tablet" without phone functions, and only 4G when there is "good" coverage. When there is bad coverage (a normal phone would show a 50% signal) my D855 loses total coverage.
May be a hardware problem?
It's a pity to buy a new one when a newer phone will have similar specs (new LG G6 will have 4/32Gb while mine has 3/32Gb) and still runs very smoothly (even more with Lineage OS)...
Thanks!
