Some timeouts when having lot LTE signal, but generally very good.

I'm disappointed. Few dropped calls with "Missed call" SMS after few minutes, on Nougat.
Found many complaining people on Russian forums....
Yes, they found a solution. Flashing modem from MM via Odin, but no OTA updates until original modem is reflashed.

I just purchased the OnePlus X and I use ATT. I haven't received the device yet, but I bought it knowing about the missing bands. How prevalent is the LTE issue?

It's an unlocked phone, which OnePlus advertises as compatible with LTE networks on both AT&T and T-Mobile. However, the OnePlus X lacks support for AT&T's most widely used LTE frequency. Further, it doesn't have support for a frequency that T-Mobile is rapidly transitioning its network to. (It almost goes without saying, but the OnePlus X doesn't work at all with Verizon and Sprint's networks, and it is not advertised as being capable of doing so.)
IF YOU USE THE ONEPLUS X ON AT&T, EXPECT HSPA DATA
That means that while the OnePlus X is capable of connecting to AT&T's LTE network, it can't in many areas because it can't talk to the 700MHz frequency (also known as LTE Band 17) AT&T most often uses. In my experience, using the OnePlus X on AT&T in New York City and surrounding areas for the past week, I was unable to keep an LTE signal for more than just a couple of minutes. Most of the time the OnePlus X was stuck on AT&T's HSPA network, which is much slower in both uploads and downloads than LTE. All of these issues also apply to the MVNOs that use AT&T's LTE network, such as StraightTalk or Tracfone.

My oneplus X doesn't seem to have too good 2G, 3G or LTE reception. I've been testing lately with different providers. The phone, in battery menu, mostly shows yellow or orange signal strenght under the battery bar. See the attached screenshots. My S3 shows mostly green bar, sometimes yellow or orange, in the same conditions. I would like to ask you: do you have something similar?

my cell coverage looks the same
never had a problem with my nexus 4
sadly i dont remember if this issue popped up with 2.2.0 or was there from the beginning

I'm on tmobile in arizona and my reception is a improvement over my old nexus5. The tmobile rep said the phone was missing band 2?? I think he meant band 12.
Anyways think the oneX has the same bands as the old nexus5.

I've issue with instable mobile network reception. Here are two videos, one of OPX and one of GS3. The OPX signal strength fluctuates between -91 dBm and -105 dBm during the video. The GS3 signal strength fluctuates between -97 dBm and -101 dBm during the video.
So it more than incidentally happens that my internet connection is lost or down from EDGE to GPRS (as well as H+ to 3G) so my internet speed drops. I also think my idle battery drain issues have something to do with it. By the way running CM13-20160521 nightly. OOS2.2.1-x is no different.
Edit: network is Hollandsnieuwe, that's Vodafone. Videos are uploading now.

opx lte
It works the band 4 (1700/2100) for OPX white? Any rom that band is unlocked in E1003?
I need this band for LTE in my country and i like the white!

The phone is LTE cat4 (150/50Mbit), so don't expect ultra fast LTE speeds.

UPDATE: I flashed the 2.2.1-X modems and the signal strength became normal
ORIGINAL TEXT:
Exact same situation with mine. I'm in Italy on TIM and I get orange levels more often than not. I never got these low levels of of reception with my previous phones.
So, either it's some bug in the displaying of the signal strength or there is some problem. I hope it's a software\firmware problem that can be patched.

I was on my way up northern Michigan and my wife drove for a bit and I compared the axon to her Moto G (2016) and it they both had to about the same signal. Both had issues shedding weaker towers. Now that we are up at the cabin both phones have very similar signal. So I think the axon is at least as good as a Moto G (2016).

Now that I am back at a keyboard I can expand a bit. I was testing via running speed tests. When I first started the Moto G was destroying the Axon. I started getting a sunken feeling, but then I noticed the Axon shifted off a tower only getting HSPA ("4G") to one using LTE so I reran a few speed tests and the Axon trounced the Moto G, as it was still stuck on the under performing tower. So that's when I thought maybe a rural roadtrip, with an iffy signal to begin with, wasn't the best way to test this. Once we arrived at the cabin we both had between 1 and 2 bars of HSPA connection that would only work in specific corners of the cabin effectively. Seemingly the same.
I know this isn't an empirical test. I wasn't comparing the actual db numbers or anything. But to my eyes, Axon is about on the same level as the Moto G (2016). I don't know how good the Moto G actually is but I remember reading it had good signal when I was originally reading reviews for it.
Once again this was all tested on the Cricket (via AT&T) network.

Up in Canada on Rogers and am having severely low signal rate. Cannot find service in any basement ive been in throughout the city. Signal of around -120dBm inside buildings. The signal seems very erratic and jumps from 96-143dBm extremely quick. I seem to think there may be a modem problem with this network. If anyone else is on Rogers please chime in on your findings.

The signal strength is worse than my s4, I checked the db and it is 5-10db worse, but occasionally will jump to being on par to the s4. Tested on tmo lte, neither phone was being held. Not sure how the rating is 4.5/5 as a reddit post agrees that there is some issue.

The signal quality is definitely not stable, had a few minor call drops if I am not in certain parts of my house and inside stores which can be tough on signals but it's nowhere near as strong as my other test phones such as the S5, Note 4, and S6 Edge+. I was dropping calls earlier this week and switched back to Note 4 and I was able to talk everywhere w/o dropped calls. This is on Tmobile and signal is decent in my area. Then on WIFI strength, the Note 4 beats it by 20-30% throughput. That's a 2014 device.
My problem with all these Chinese brand phones is they have great specs but software is lacking. Looks like I maybe back to my workhorse Note 4.

So I used this phone to drive Uber in Los Angeles all last night and had some pretty major problems.
GPS Signal would randomly shift positions so Google Maps would keep rerouting during trips. This didn't always happen, but happened enough to be annoying.
I'm pretty sure I lost a bunch of trip requests because they just never got through to my phone.
This is either because the OS wasn't allowing the notifications to come through correctly, or because of the network performance.
Interestingly I was streaming podcasts the entire time which came through fine for the most part, but they would cut out every once in a while if I ended up in areas with 1bar (which happened often last night).
This is a pretty major problem for me, I don't know if something like Cyanogenmod will fix me not receiving requests, but the cellular and GPS performance are very clearly performing poorly.
Edit:
Cellular performance is now much better after the update.
I would say it's on par with average smartphones (I still lose reception where most people do), and it no longer just drops and stays of signal for no good reason.
GPS performance is OK, it tends to shift around while I'm driving a bit (thinking I'm on the street next to me).

Antenna Strength
Has anyone been able to confirm that this is due to a bad physical design of the antenna and not a software issue?
I was ready to buy this device until I saw these reports of bad signal strength

Hi guys,
Can any European users comment on radio signal performance? Could the issue be limited to the US version?

To asnwer my own post, it seems some amazon.de customers are returning the phone due to very poor reception.
I was soooo looking forward to buying this phone and am shocked that ZTE would put it on the market with such a problem. Time will tell if it is hardware related (which it probably is), but most likely my money will go to another brand. I sooo wanted good sound :crying:
EDIT: please, any feedback from European customers?

There are some reviews about the cellular strength on a german forum (android-hilfe.de/thema/empfang-des-axon.792336/) but without any comparison to other phones.

Radio Performance
The Pocket Now review of the Axon 7 mentions potential radio issues and compares it to other phones.
Axon 7 Signal Strength
It doesn't look good.
I wonder if the new "Mini" version of the phone has the same issue and if not, perhaps they corrected a hardware flaw.
There is a new software update for the Axon 7 coming soon. I hope it addresses the signal strength issue, but I wouldn't hold my breath. We may have to just wait for the Axon 8.

when new software coming.

Note 3
Cellular: -93 dBm
Wifi 5ghz: - 46 dBm
Axon 7
Cellular: -118 dBm
Wifi 5ghz: -59 dBm
Can't perform an LTE speedtest on the Axon 7. It won't hold a connection long enough. Web pages constantly fail to load.
Signal strength is significantly worse than my 3 year old Note 3. So much so the phone is unusable at home.

I commented elsewhere on this as I'm mainly sending the phone back because of the very poor camera and the disappointing audio.
The radio however is the worst I've had since 3G was launched. I've been all over Brussels today and barely seen a 4G signal. I'd forgotten 3G existed until today. I managed to get the Axon to connect to 4G by toggling the mobile data on and off but it quickly went back to 3G.
My bedroom is in the basement but thanks to a nearby base station I get four bars 4G on my Honor 7. The Axon get one-two bars on 3G.
I'm bailing out now. I'm not waiting for a software update to fix the radio and I'm not sure the camera *can* be fixed, it's that bad.
The lovely screen apart, the A7 is a downgrade from the much cheaper Honor. Shame.
Grey Axon 7 purchased from Amazon Germany.

LTE: Nexus 5X: -105 dB, Axon 7: -113 dB
Forcing 3G on both phones: Both about -95 dB.

European version
Indoors in a café. Both of our phones are on the same network using the same base station. The Nexus 5x shows -106dBm on LTE while the Axon 7 shows -111 dBm on HSPA and is unable to load a page.
A bad camera, broken audio and a weak radio now seem a heavy price to pay for a nice screen and a top of the line chip.... it was too good to be true.

When I was walking home from campus today, I had 4G with a maximum of 2 bars missing (one missing most of the time, sometimes full bars) 90% of the 3km trip. Don't have any other LTE phones to compare it to, so take that with a grain of salt.

I get a low 4g signal at work whereas on my s7 edge I didn't get anything

Mine is a lot better than any phone I've had before. Usually at home on all my other phones I have 1-2 bars and on the S8+ I have at least 4 bars.

Bars are no indication of true signal strength. My S8+ doesn't get nearly as strong of a signal as my Pixel XL. I drop signal a lot more often now. I was rather disappointed with the performance of the cell radio actually.

For me, the signal is about the same at home. But at work, the S8+ performs much better than the Note5 that I had... Must be an extra band or something. The Note5 would hang on to an unusable LTE signal or drop to 3G/1x inside my job. The S8+ stays on on LTE with a usable signal.

It's worst Then S8 as I used that before shifting to S8 plus. But download speed is great.

My S7 was better. The S7 ised a new duel antenna tech, I am not sure the S8 used it or not.

My AT&T Note 4 and my new S8+ get about the same signal, which is really disappointing

I generally see around 5-8dbm better then I did with my pixel xl at home..notice the s8+ does drop signal little easier tho then my pixel in fringe areas

Tested right outside my house. Never had these speeds on my Note 5.

Comming from a S6, the signals and speeds are far better, also my s6 was missing a few bands so never ever got speeds like this on my Jio 4G Network in India

At work on LTE Im getting 31 Mbps down and 6 Mbps up. Not bad! Faster than our company wifi!

Poor Reception in Canada on Bell Mobility
I just got an unlocked S8+ that was apparently originally from Sprint (because that is where the home page goes in Samsung Internet).
I do not get very good reception on it – even in urban/suburban areas. Sometimes, when I am inside a building, it disappears altogether. I often get 1 or 2 bars on the reception indicator. If I check the “Sim Card Status” screen under settings I get -105 dBm 3 asu. I don’t really know what those numbers mean.
Is there anything I can do to improve reception? Should I be calling Bell and maybe they need to know what kind of phone I have? Should I expect an S8+ purchased directly from Bell (they also carry this phone) to have better reception? Or is the reception of “105 dBm 3 asu” fine and it’s just the indicator showing low levels?
As much as I like this phone I cannot be missing calls randomly. I have a business to run.
Thanks.

Hey fish you want it down, the dBm i mean. Here's a quote "-50 dBm is great signal or full bars. -120 dBm is very poor signal or a dead zone." you at 105 dBm is garbage, no wonder your missing calls.. Since you are experiencing network issues, you could get a replacement, but i don’t think it will make much difference. as it's all same hardware. Why not get a Google Pixel XL i heard they got awesome reception! Or if you’re at home a lot, purchase an lte repeater booster ? Problem Solved!

I went through a whole “carrier switching” routine (details found somewhere on these forums) and after changing the CSC to Canadian I flashed Bell Mobility's firmware. The phone now shows that it’s an SM-G955W which is the Canadian model. And apparently now supports additional LTE bands 29(700) and 30(2300) which were missing from the SM-G955U (I determined this by dialing *#2263#).
I have no idea if it *really* supports these bands or just *says* that it does but my gut tells me that it really does support them. I suspect that the hardware for the SM-G955U and SM-G955W is 100% identical and any differences are controlled through software only.
And I seem to have better reception now. I am getting 4 to 5 bars in most places and under -100 dBm in most places. Plus Wi-Fi calling works now so I have reception in my basement at my house.
The true test will be when we go camping next summer.

I've had really good signal on this phone, along with great LTE performance. On 5G NR, performance is decent considering it's a new technology. I leave my phone on LTE 99% of the time because 5G drains the battery however.

But I've never seen over 5mbps in actual use.
But wait:
