[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

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?

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.

f240k wifi issue with random disonnetion and poor speed and poor reception

LG G3 Signal lost on 3G network

First I want to say to all of you moderators - I'm looking on this site and other for the past week - and there is no similar posts for this problem.
Now for the issue itself:
I just bought my brother the LG G3 D855. It has been working great for about 4 months, but than he flew to NY and when he got back, the signal strength got down to 1-0 bars.
after a week of test, and changing ROMS, and also talking to technical support from the currier (ORANGE) , I narrowed down the problem to this:
the problem only happens when in 3G network, thus going down to GSM or catching the right antenna with LTE, the phone works fine - the minute it connects to a 3G antenna it looses signal and gets stuck without switching to other antennas. I've been on the phone with orange for hours, and since we live in Tal Aviv, there is no way we don't have sufficient coverage. Tried different ROMS and no luck with none of them. Finally today I gave up and send it to the lab.
I'm posting this because I haven't found the proper discussion here for this problem, and also wanted to know if anyone have more experience than I have with this issue.
thanks guys

Thanks for sharing this with us. I am really interested in final results! Waiting them and crossing fingers for resolved issues!

LG G3 D855 dropping signal

Hi guys, my LG G3 started to drop network signal. When I switch to 3G only mode, it gets full tower signal, but suddenly after some time it drops to about 2 or 3 bars. Letting 4G mode I barely get 2 bars.
I tried 3 different ROMs and the issue continues. Is it something related to the antenna? Replacing it could resolve this?
Thanks!

Question Horrible signal connectivity?

Hi all, I just recently bought this pixel 6 pro a few weeks ago and I've been having horrible connection issues. The main one that plagues me is when all of a sudden, for no reason, I lose mobile data connection. I have some bars of signal with the LTE or 5G icon but with an exclamation point in it. Or sometimes it just loses signal randomly like in the screenshot below. Both screenshots were taken minutes apart.
I've noticed this was an issue for most people and have posted about this here, but I haven't seen anyone complain about it recently. Is there a fix for this problem?

Unfortunately for a great manu people, myself included this phone has garbage reception. There is no known fix.

Me to

My troubles began after I updated the phone to A13 enrolling to Beta and then leaving it.
The problem was that the phone will be stuck to H+ all day although weI have good coverage of 4G and 5G in town. Sometimes the connection would just drop and I had to engage flight mode to reset it.
Yesterday I decided that I had enough and did the reset of network settings. Today I have noticed that the problem was solved. Now I have 4g and 5g as in the past. But the problem now is that the Internet just would not work from time to time although it shows full bars. Had to use aeroplane mode again today about 3 times.
It's very annoying to say the least. Had thoughts of changing the phone. Not even speaking about heating issues when on mobile. Horrible.

I also have to occasionally switch on/off airplane mode when the phone cannot connect to the internet from time to time

i agree, terrible signal problems, all time. I`ll try to reset all network settings
for me it`s a disrespect from google to treat all final user like beta tester

Same here. Super slow connection even in areas with towers close by.

Been having this issue ever since I updated to Android 13.
Having only had the phone for 2 weeks, I took it to my provider who said all they can do is return it to Google. With both my eSIM and my physical sim dropping out together, apparently its an RIL problem. They did say that if it's just an issue with one SIM card, replacing it will fix it.

I think this can be solved downgrading to android 12.1 dev you can downgrade to android 12.1 without downgrade bootloader it's safe and don't brick your device because it's a android 12 that runs over android 13 bootloader. Keep in mind that this will erase your data permanently! Do a backup before do it

This has been happening since the phone came out. This is due to the old modem they are using from Samsung. There is no fix.

My coworker has this happen with his 6 Pro, while my 6 is perfect ironically. He has verizon, I got tmobile. He has to leave the store to make a call, but I don't. This has been for the last 6 months though

Had the phone sent away to Google for repairs as the issue ended up happening when I was showing my provider. Got it back and Google said there were "no issues" with it and they couldn't replicate it with either SIM type. Either they put out a hotfix or it magically went away, but I'll see how it goes after using it again.

If you've got another phone (5G compatible), you can try to see if the problem is the phone, or the actual network coverage.
Also, something else you could do is switch to 4G and see if the problem persists.
The thing with 5G is that the coverage is really spotty. That's in general. I don't live in the US, so I don't know what the actual coverage is over there. But that's a general thing with 5G. It cannot penetrate as well as 4G, and even worse than 3G or 2G. When you increase frequency, you lose distance (coverage). So basically 5G needs a lot more repeaters to get proper coverage.
But you could try another phone in the exact same area. Oor..try to switch to 4G and see if the issue still occurs. You could also call the carrier and ask if they have any idea why is this happening.

Facts, I changed from 5G to LTE as my preferred Network and have much better connectivity

Same with me. I keep 5G turned off for a couple reasons.
1, battery life.
2. 4G is fast enough for me.
3. Better signal.
