I changed telco recently, to SFR (in France) and am getting very poor 4G reception at home. I haven't used the data connection at home before (because I have WiFi) so I didn't know what to expect.
The mast is only 2.8km away and LTE800, so the OPX should like it. The SIM card works well in my partner's Xiaomi, and in my old cheap and cheerful Alcatel POP4, and both get a strong and stable 4G signal. So why is my OPX struggling? I've been on to the support at SFR and they are going to monitor the line but said everything looks ok (APN details good, no local outages, etc) so it should work.
The only strange thing that might help in problem diagnosis is that I had to create the APN myself. The correct one was not displayed on the OPX - several other telco APNs were displayed (around 15 in total) but not the one I wanted, which I find weird. In the other 2 phones (Xiaomi & POP4), the correct 2 APNs are the only ones displayed.
Do you think there's something wrong with my OPX? Is it simply 'weaker' than the other 2 phones I have? Might it have a problem with that particular mast? (I get good 4G elsewhere) This one baffles me.
Nobody any thoughts on this?
It was suggested to me that perhaps the OPX designers compromised 4G reception (due to limited physical space) and upper band LTE is advantaged over LTE800. because the majority of 4G provision is in that upper band.
I have noticed this too!
Consider I live in a little country where 4G signal is low.
The same happens in Rome where 4G signal is high!
In fact, with Mi A2 lite I have no problems.
Probably the hardware is not very well designed, like you said above.
I don't like to resort to unhelpful, nontechnical language so consider this as venting - 4G reception sucks on the OnePlusX!
I'm seriously considering getting another phone (and I otherwise like my OPX) because its 4G reception is so weak. Sure, it works on occasions but I know other phones do better. Still, I guess it is now 'old' technology!
It looks allright with my OPX in France too, with Prixtel (Orange).
I have my main Sim card with Red SFR in my main phone, but with the OPX, the 4G DL and UP speed are good.
With Prixtell, I get this right now:
Hello,
I have a same problem with Bouygues, I have a better connection with sosh/orange...
the Bouygues/SFR antenna is at 3km
orange/Free is at 1Km
and traveling by car the reception is less cut with orange / sosh
I've come to the conclusion that it's the OPX hardware and/or design. Nothing we can do about it... other than get a different phone!
Fortunately for me, it's not a real problem - i's just a limitation, a bit frustrating and somewhat baffling. As I said, my cheap and ordinary Alacatel phone has a better 4G reception!
Are you by any chance using dual sim cards? I've noticed that my 4G reception is also worse ever since I started using 2 cards.
Also, reception appeared to be better on stock Oxygen OS than it is on LOS15.1 that I'm using right now.

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.
I have a standard EU model on Vodafone. Several times now I have gone to the same pub with friends. Inside, I always drop to GSM connection while my friends' S3, iphone 4 and galaxy nexus consistently manage to hang onto HSDPA+. This happened during a trip in the mountains as well. It's becoming increasingly obvious that my G3 has a worse reception than most other phones.
Is this expected? how can I improve the situation?
I agree with signal issues. I'm sat next to my partner both on Vodafone.she got a iphone 5s. She has 4bars of signal and im on zero.

The G3 has known problems on Vodafone(Vodafones fault)
I have had an M8, 1+1 and the G3 at the same time and the G3 is by far the best and on a par with my Nokia 1520 and the 1+1 was the worst. I have now sold both the M8 and 1+1 but they both lost signal quicker and were slower to get it back again and the G3 has slightly faster speed over 10 tests each. The WiFi was better on the M8 as it connected to my home WiFi before I got out of the car when I parked outside. They all work fine in the house so no difference.
My phone is a sim free 855 on EE and the WiFi is Sky. I haven't tested my other one yet but it seems to be the same.
It's happening to me. Also I had lost completely but fixed when reboot. I don't understand why. I heard put copper tape under the back cover for improve signal. I'll try and then let you know.

Vodafone Portugal I have issues too. Too much I think.
You people do realise "bars" of signal are meaningless? A "bar" is not a measurement of signal (it happens to be a measurement of pressure but thats is besides the point.) Phone signal doesn't really have a unit of measurement so it is given ASU (Arbitrary Strength Unit) which is based off the power of the signal (dBm) Go into settings, about phone -> Network and you will see the quoted ASU and dBm.
Therefore the way signal is represented by bars on a phone is entirely down to how the manufacturer chooses it to be displayed. For example 1 bar could represent 1 ASU on an iPhone, therefore a full 5 bars would mean anywhere from 5 ASU upwards. Whereas on a G3 1 bar could represent 3 ASU, therefore giving a larger display range.
Now I have plucked these figures out of thin air but I think you can see from that example how 1 bar on the G3 and 3 bars on the iPhone would actually be the same signal strength.
Granted if you have NONE and your partner has some, then that is clearly an issue. But don't compare bars, compare ASU.
Just wanted to add my experiences that I've had with my G3 for the past 2 months.
My G3 continuously gets a weaker and more unreliable signal (Three UK) than I have had on any other smartphone I have (One M7, One X+). It's incredibly frustrating as it means I never get LTE indoors but more importantly, my phone will very frequently lose data and cellular connection if I put it in my pocket. What good is a phone if it drops signal while its in your pocket?

Wow, you got 4g on Three network, I went to Three from giffgaff and I had faster speeds on giffgaff 3g than I did with 4g on Three. I'm not on EE and very rarely lose 4g
Are you using a sim adaptor buy any chance?

I moved to Three from giffgaff and my speeds over both 3G (HSPA+) and 4G LTE have been consistently faster than anything I had on giffgaff. The city where I'm at (Newport) was not on the list of planned 4G cities for 2014 from Three, but it just started rolling out near the start of this month. I'm wondering if it was a rushed rollout to cover the area for the NATO Summit that was in the area a few weeks ago. I've averaged 20mbps download over LTE and about 7/8 down on HSPA+ which are both better than the 3mbps average I had on giffgaff. I'm not using a SIM Adaptor either, the Micro SIM that was in my HTC One M7 fit right into the G3.
I just wish the G3 kept a stronger and more reliable signal, these signal drop outs in my pocket and less reliable elsewhere are defo not Three's (or another carrier's fault), I've never had this issue with any other smartphone I have had. Poor show LG....

I would have to disagree with you about the reception on the G3 in my case at least. Both my G3's have better reception than my M8 or my Oneplus One. The G3 even keeps signal(albeit low) in my lift.
I'm in Solihull by the way and according to Three I should of had 4g inside but didn't even get it outside and only got good 4g when I went into Birmingham. Must also say that when I tried Three it was in my Nokia 1520
No problems here compared to my xiaomi mi2.
Same or even better reception.
I have the G3 on T-mobile (USA) and its the best reception phone i've had. Constantly gets LTE where all my previous phones struggled...
(I had HTC One m7, Nexus 5, Z1s, Galaxy S5... to name a few)
Have you noticed your G6SE is dropping calls and has overall poor reception?
I've had mine for four days now and have dropped many calls and lost signal where my previous phone managed to easily retain the network and never dropped calls.
Also I noticed when connected to my car's bluetooth, the signal display never shows full strength where again my previous phone always did. The GS6E only ever shows 80%
20150424_222933-1 by markcaigerwatson, on Flickr
when looking at my signal history in gsam, it also never goes above 80% which ties up with what my car's display.
Screenshot_2015-04-24-22-15-33.png by markcaigerwatson, on Flickr
Now i've made a comparison between my M8 and the GS6E and this clearly shows the GS6E is less sensitive to cell reception and this equates to the dropped calls.
The M8 can achieve -69 dBm at one one one point
Screenshot_2015-04-24-22-52-42 by markcaigerwatson, on Flickr
and the GS6E a lower -81dBm
Screenshot_2015-04-24-22-56-54 by markcaigerwatson, on Flickr
Ok, so the GS6E is not as good as others at cell reception. Is this a hardware limitation? or could new radios help this?
What is your experience of this?
There are various reports cropping up now about this

Veedubs unite!
What country and carrier are you on?
I'm in the US and on sprint and drop calls like crazy with my gs6e. Never had this issue with 10 years on sprint. I've noticed that I seem to drop calls more frequently while travelling on 9 at high rates of speed. It seems to be a tower handoff issue. I don't have the issue whilenjoying stationary.
I'm on tmo (US) and no issues. Honestly I've not read a lot of complaints about cell reception or at least no more than usual on any device. Regardless of that why I chimed in was really to say that my first phone was defective. The issues I had (horrid batt despite trying every fix mentioned here and all across the internet, fingerprint scanner was about 50%, again tried every possible fix I was able to scour up. New device and the fingerprint scanner immedietly worked perfectly and my battery life was fixed without me doing a thing. Keep in mind that by fixed battery I mean I get about 4 hours screen up time which isn't good but about what I would expect for a small battery in a bloated device.
Long story short, consider exchanging it. The lack of reports that speak of bad cell reception imply you may have a lemon to me.
Did you click on any of the links I posted in my original post? There are more too, but i thought that was enough.

Yeah love the VeeDub!
I'm in the Uk on the 3 network...
Here is my wife's 2013 Moto G next to my 2015 GS6E. She is also on 3. As you can see the Moto G performs much better than the GS6E. Moto G on the right obvs. It was also £500 cheaper!

Definitely some poor signal reception on Galaxy S6 Edge. Mine has poor signal reception as well. Bought mine unlocked in Hong Kong model 9250.
If I tell one of the people in HK about this they will give me the same old lame answer that no one has complained about thus issue yet.:silly:
Poor reception on China Unicom in China, poor reception on CHT in Taiwan and poor reception on CSL in Hong Kong. Last but not least is Wifi reception is literally horrible unless you sit or stand right next to Wifi router!
Yep I'm having the same issue with my S6 Edge to. At first I thought it was my network (Three UK) but after doing some research, I'm reading the issue is more widespread, internationally 2. Calls keep dropping when I'm on a call and I'm getting a bad reception in places where my S5 didn't. Really not happy about this. I hope this issue can be fixed with an update.
Experiencing the same issue. I put my S6 edge, old S4 and iPhone 4 + 5s side by side and they all have max signal while my Edge had just 1 bar.
I've been researching and somehow got to the Sprint forums where they were also reporting the same problems. I saw there that you could try switching to CDMA only. Tried it and while it did improve the signal, it prevented me from using LTE which I'm not really willing to compromise.

it is called Network Signal Info.. Free from Google Play.
This is in México City full LTE with my Note 4 , but the EDGE has This really poor reception.
The Phone is faulty or is the same case as others report on signal issues?
Same here for me on EE in the UK, switch to 2g/3g and signal is fine, set it back to 2g/3g/4g and 1 bar
Not sure what the problem is with this Galaxy S6 Edge but the 4G LTE reception is poor and download speeds are slow.
Same for me. I m in France near strasbourg with operator orange. It works fine with iphone but not with my galaxy s6 edge! !! With the same sim card of course!
Sent from my SM-G925F using XDA Free mobile app
I have not been able to connect to LTE since I got the edge a month ago. I'm currently on OE3 if this helps. Could this be a hardware issue?
I have received a few updates on my Galaxy S6 Edge but until now the wifi reception along with 3G and 4G reception suck. Even when reception is great or average the download speeds suck and are about half of what they are on my iPhone 6. Was expecting better results out of this phone but I guess not. My guess is that they either intentionally turned down the power provided for cell reception and wifi reception for longer battery life or their antennas on this smartphone really suck. Definitely a problem that Samsung needs to look into.
Mine is also struggling with connecting to stuff. 4g is spotty, calls drop and break up, wifi is shockingly bad, even in the next room to the router. 1 bar or no service on EE UK in a good signal area.
Going to call Samsung tomorrow and if they have no solution, it is definitely going back.
I am going to get rid of this Galaxy S6 Edge when the new Motorola comes out. The reception for both wifi and cell signal are beyond horrible on this phone. Battery life is quite poor as well. Try making a call using speakerphone if you have to talk while driving and see how many people tell you that you sound horrible. Samsung should learn a thing or two from Motorola,Apple and Blackberry when making phones for phone calls.
Samsung dropped the ball with this phone in two areas: Battery and Reception.
I am moving to a new phone as soon as I can sell this.
Had my x1 for a couple of days now and lots to like about it however I have noticed that it seems to have a very weak phone signal reception.
I am on three in the UK and in the normal areas I travel I have never noticed an issue on my other phones with it struggling to hold on to signal bars.
Anyone else have this?
Signal bars mean absolutely nothing. Many oem even show full bars even when there is actually no signal.
Better install cellmapper app that will exactly show and record the signal where you travel.
Also, do you have 3uk volte working?(calls over 4g network)
Well all I can say is that I live less than a mile from the nearest mast and would nearly always have full signal bars on other phones yet on this phone it drops on and off 1 bar.
I will download the app you mentioned and see what that shows
I've had this problem with numerous Sony phones over the years, always poor signal compared to Sammy's, Pixel's and iPhones that I've had. Same issue with the X1 I have now, always on WiFi calling and no signal, my Pixel 3 XL would be happily sitting on 4G.

Glad it's not just me then.
I do remember having this issue on a previous Sony phone also but can remember the model now. It's been a long time since I had a Sony but thought this one was going to tick every box which it almost does apart from having reliable signal reception which is really should be a must!
Is there anyway they can improve this with software of are we stuck with it due to hardware issues?
I'm in my 14 days returns periods at the moment and like everything about this phone apart from what it should do first and foremost
I am having the same problem, I'm on EE and my LTE keeps dropping from 4 bar's to 1 bar then nothing which causes me to lose data connection. It then jumps to 4 bar's again and then repeats this over and over. This is happening at home where I always have full reception. I have tested my sim in 5 different phones all have full reception and don't lose connection only my Xperia 1 does! Any help would be appreciated.
Same problem for me. I switched my SIM from Galaxy S8 to X1. S8 has 4 to 5 bars while X1 struggles with getting one bar at home.
Ffs... The bars mean nothing. Sony phones take into consideration RSRQ(signal quality) and SINR(s noise) values of the signal. Other oem don't. The actual signal power RSRP (do not confuse it with bars) is same or better on Sony.
Xperia 1 has most advanced modem and antenna setup of any 4g phone. 4x4 mimo even on low bands (first to have it).
3uk and ee are special in the sense that they need phone to support volte to get access to their low band spectrum(band 20).
So make sure you have volte aka 4g calling enabled and check with apps like Netmonster or Cellmapper the band and RSRP of the signal. Then compare it with other phones at the same place.

If it's as simple as that why is it not enabled on this phone already?
I think what you seem to be over looking is the fact that I and others here have said that yes the bars are lower than other phones and flutter slot but also to the point where they drop completely and give no reception at all. A situation not faced on other phones.
Can you explain how we enable this missing band so that the phone can provide a more reliable/stable reception
Does your phone have 3uk volte(4g calling) enabled? Phone should stay in 4g during call. If not then you are out of luck.
ee users can install EE firmware to get Volte working if it's not already . newflasher on xda helps to change firmware.
And please compare signals with abovementioned apps.

If you're having signal drops / dropped phone calls etc... I get it. But Sony is historically notorious for showing lower signals than others on those bars. However, as stated, the bars are pretty meaningless. I've owned many Sony's, and while the bars are lower (sometimes all empty), I still have signal in all the places I should. YMMV.

I don't honestly know. My phone was purchased sim free from carphone warehouse and I use it on 3 network. The phone just set itself up. How would I check this? Is it something listed under network settings?
It's so frustrating as I'm really loving a lot about this phone but just want it to be comparable at least with my other phones I've used with call reception
those who are having signal problem, are you using EE network?
I saw lots of people with EE reporting this issue on official sony forum.
Got mine yesterday from Vodafone and signal is perfect !

Yes
I also have only 1 bar... Orange.
If you are EE UK user, then you need EE firmware on your Xperia 1 to get best network compatibility(Volte and low band support because of it).
3UK users probably need also 3UK firmware but that does not seem to exist yet.
This weirdness of low band access is specific to two UK operators. Everywhere else the device is fully capable of best 4g experience.

So for those of us on three network but purchased the phone sim free are stuck with the problem as three do not sell this handset themselves so unlikely to release any firmware for it.
That does not look good for me so I think I will need to return within my 14 days.
Shame.
There's definitely a network connectivity issue with the XP1 right now though. This seems to affect only XP1's on the EE network, which were *not* bought from EE direct, i.e. ones with stock firmware. (e.g. mine!)
The symptoms are that periodically, first the 4G symbol disappears, then the signal goes to zero and you've lost the internet. Then it reconnects back onto 4G again. Sometimes this repeats 3 or 4 times in succession. The whole thing takes from 5 seconds to maybe 30 seconds depending on how many re-tries.
You can go for maybe an our or so without a problem, or sometimes it happens like every 10 minutes.
And here's the key part: this happens wherever you are, even on a full strength signal. As far as I can make out, this affects ALL XP1s with stock firmware on EE. EE say it's a Sony problem. Sony say it's a network issue. So we are all stuck.
Does anyone know of a suitable network logging app, which will log 4G disconnects and signal loss, so we can provide evidence to EE and Sony?
More info here:
https://talk.sonymobile.com/t5/Xperia-1/Issue-with-network-dropping/td-p/1376332/highlight/false
(My phone is fine with a Vodafone sim. There's something specific to the phone firmware/config - timers, buffer sizes, packet sizes - whatever - and the EE network. But right now, on EE, it's unusable.)
So I purchased a XZ1 G8343 which is meant for Canadian carriers, but also works in the US with T-Mobile. I have years of experience with my HTC M8, 10, and U11 with customs ROMs and they all work amazing with my SIM card.
What I have done is unlock the bootloader on the XZ1 and installed the latest CE1 firmware for the XZ1 and added the oem_X-FLASH-CUST-C93B file from the G8441 firmware to retain VoLTE and Wifi-Calling. This works to enable those features. T-Mobile considers this IMEI not compatible because of this, but flashing that G8441 files fixes it. The IMEI is clean.
My issue is this. The mobile data and sim network signals are extremely polarizing. When I'm in my apartment, it's completely weak and no networks are there. When I go outside on my balcony, great signal strength. I work as a delivery driver and gave this phone a test run . . . and it was BAD. I'd be losing signal almost everywhere and it reconnects randomly in other areas very close by. I don't see what would interfere with it so much, since this doesn't happen with any of my other devices. It seems way too sensitive.
This is weird because none of my HTC devices have these issues. I looked further into the specs and noticed the G8343 model is missing a few signal bands the G8341 model currently has. But it also supports more bands than my HTC U11 (unlocked) which gets network connection everywhere I need it.
Am I looking at a possible radio antenna hardware issue?
I have the G8343 also.
I live near Chicago and mostly have no issues with signal (LTE).
But, when I travel, many places I only get H+, or similar low signal connection.
Any ideas how to make this work better?
I have been looking at flashing other ROMs, but I cannot find any (particularly stock, like one for G8341) that say they improve the connection.
The CE1 is Central Europe, and I am not sure that would make the signal better.
I have not looked too much at the other ROMs, because I'd like to keep all the Google security stuff in place and not have to tinker with something like Magisk, which I had problems with on my previous phone.
Any help greatly appreciated!
