Hello everyone, I live in Hong Kong and bought a Pixel 5 GD1YQ. The phone is great, but the network performance is not as I expected. I even suspect my Pixel 5 has a defective modem. I use the app NetMonster to check the bands that my phone connects to. It rarely shows LTE-A, but only connects to one band. What's even worse is when it connects to band 1 (2100 MHz), it sometimes drops internet connection and shows an 'X' in the signal bar, the signal bar is full though. I had an Xperia 1 before and it always connected to multiple bands (CA) wherever I go.
I have a little request here. Would you mind telling me whether your Pixel 5 always does CA or not. Also, if you have another phone, how is CA on the other phone comparing to Pixel 5? I just want to know whether my phone has a faulty modem or just isn't compatible with the carriers in Hong Kong? Thanks in advance.
Update: I just found that when I use another carrier, the phone changes bands more actively. So, I guess that's a compatibility problem. Now that I want to buy one more of another colour.

Some time ago I purchased the SM-N920C model form Amazon.com 3rd party seller here in US and it turned to be model from Emirates, it worked just fine last months of 2016 but this year I noticed the signal reception is not as strong as it used to be with T-Mobile, even though I live in the same (Miami, FL area) place and use it same way. It is international model version unlocked with 32GB memory.
The Amazon published the compatibility chart recently for this phone which shows "partial compatibility" with Voice/Text and data, whatever it means, the phone receives/sends calls, text and LTE data no problem. It is just the phone sensitivity that dropped in past few months and I thought the possible cause might be that the phone does not cover some GMS and/or LTE bands hence the problem with "weaker signal reception". I am also aware that T-Mobile has been switching between bands in my area in past couple of years disconnecting some of them permanently, not sure about details though.
I am aware most of those modern phones have multiband radio chips that can be configured in variety way so I was curious if there is alternate modem FW out there for my phone that I could flash to improve phone reception.
Is there?
Attached is the existing FW info. I would appreciate help in this matter, thanks for reading.

Hello,
I am new here and this is my first post. I do not know if there is a special thread to present me so let me do this here now.
I am 31 years old an live in Germany, I like to test, repair, restore all kind of things. My english is not very good, but I hope you will understand my problem.
Actually I bought a damaged Samsung Note 5 N920V (Verizon) in the US and now it is working very fine. Some parts have to be substitute by new ones, but everything important is working fine.
I think you all know the problems with band frequency of Note 5 Version in Europe. The signal ist not the best one because in the US they use other frequencys for GSM/LTE/UMTS and so on...I think you know what I mean.
Now I saw that the Note 5 Version N920C is fully compatible with european band frequency. Somebody want to sold the chargin port platine with softkey buttons and atenna and so one...the whole platine.
I want to ask you If somebody knows if it is possible to build in this part from the N920C Version into my N920V Version to get the european band frequency I need? Or is band frequency "blocked" in the software and this parts are absolutely the same?
Hope somebody can help me.
Thank you.
Kindly,
JeBaFe
I'd like to figure out this too. I managed to 'allow' LTE bands via QXDM (like here) but it still did not appear in Service Menu (2263 - LTE Bands Preference) so I guess it is some other low-level software restriction (modem firmware maybe). I'm getting poor signal reception in Europe and no LTE...
Hi,
the first of all problems is, to get into the service mode of an Note 5 N920V....or I am wrong? Actually I found no working solution for this. King root does not root temporarily on a N920V...
The second problem is, if the antenna of the N920C is adaptive to the N920V and if the signals are now covered by the new antenna, we should have problem number 1....we can not get into the service mode to unlock the needed LTE frequency? Right?
Somebody there who can help?
Kind regards.
U can change your network setting by dial *#2263# on your phone keypad.
Hi,
this does not work. I tested it some days ago...
I think the antenna board / modem is the problem.
But I am a little bit afraid to test it.
I rooted my phone (920K).
Usually it is low network signal indoor.
I dial*#2263# then service mode appeared. In Network setting select Band selection. Then i chose LTE/WCDMA/GSM. Then restart phone and wait a while to see what happen.
Hi, my Note 5 is from Dubai, does it mean I may encounter network issues here in Switzerland?

This depends which Networks are used for 3F / 4G in Swiss and Dubai. If they use the same frequenzy it should be no problem.
By the way....I swapped a Motherboard / logic Board from a Note 5 N920C to a Note 5 N920A and it was no problem. Now I can use my Note 5 without any problems here in Germany. :good:
So I can say now, swapping a logic board from one Note 5 to an other is possible. :good:
Hello everyone,
I bought two Realme X50 5g from Amazon uk and I was really excited when the phone arrived, from what I read everywhere was a lot of value for the money. However just after a few hours of use I was really disappointed to see the behaviour I am having in both phones.
I can connect to the wifi 5g band without issues and I get internet, the problem is that after a while (randomly can't tell 1 hour or 10 hours depends) when I check the phone it says "no internet" and I can't access anything, I need to disconnect and connect again and the internet comes straight away.
This issue is a little bit annoying because it means being disconnected for a while until I realise about it.
I am in the UK and I have Virgin Media and was using their SuperHub 3 which has worked really well with any device until now. I tried to change the config from dual band and add 2g to the 2g ssid and 5g to the 5g ssid so they were separated so it doesn't use dual band automatically and is the same. I was suspicious the problem could be the VM router so I bought a new router TP-Link Archer A7 AC1750 which I believe is a middle range router which supports dual-band however doesn't have all the high tech technologies like mu-mimo and beamforming. Anyway I got the router setup everything and have been using the Tp Link instead an the exact same thing happens.
I am with EE as carrier and I don't have yet a 5G plan, however as soon I turned on the phone with my sim EE sent me a test saying that they have enabled VOLTE since I am on a device that supports it. I may be wrong but I am also getting the impression the issue tends to happen more frequently if I have received or done any calls, but I have no hopes on getting support from EE.
I have contacted Amazon support which was hopeless and I have sent an email to Realme support but I haven't heard from them yet.
I am starting to consider to return the phones and get a refund but if I need to get to that will be a shame because the phones does looks nice and I have been enjoying it, I like the UI and the performance is quite good.
With all said I was wondering if anyone is aware of any issues with the Realme X50 5G and the 765G SOC wifi?
Thanks in advance
Hello guys,
I'm using Mi9T Pro with Stock EU rom MIUI 12 version 12.0.4
I have this issue with Xiaomi regarding how the system handles prioritization of Network Band when it comes to using Mobile Data connection.
We know that we have options to prefer 4G, 3G or 2G. But it doesn't define which specific band. Like for example, 4G can be 4G/LTE or 4G+/LTE+. These 2 networks seem to be the same but these actually have different network bands
The question is how does Xiaomi system prioritize which band to select?
Does it prefer the one with higher signal or the one that pings better.
I have this question because as I have experienced, Xiaomi system seem to prefer the one with better signal regardless if it can't even pull any data. In short, it will keep connecting to a network with a better signal strength even if you won't get any internet connection out of it.
I've been noticing this when I set my phone to 4G preferred in my location. When signal indicator turns to 4G/LTE. It may seem to show you that you're connected to the internet but you can't really browse anything because there's actually no data for that band. But when it turns to 4G+, that's when I really get to connect to the internet.
And the biggest problem is that the system prefers to connect to the 4G band. That's why I'd prefer using 3G network because I have a more stable 3G+ signal here.
Another thing that's really disappointing is that my other phone OnePlus 5T handles this well. We share the same APN.
Sadly there's no band selection in *#*#4636#*#*
It would be glad if anyone could provide a better solution to this.
Thank you!

4+ g usually means (specially on Xiaomi phones) LTE Advanced Carrier Aggregation where no other/different bands are used but instead the phone is in parallel attached to more than one 4g band. As such, it increases the speed (and maybe, in your case provides a fail-over?!):
https://www.gizbot.com/mobile/featu...ifference-between-4g-4g-explained-053769.html
However, there is another question why (on that place) you have strong 4g signal with no Internet, so that when your phone switches to CA and in parallel attaches to another 4g band (maybe with a weaker signal) it obtains Internet connection over that second band
At least to better understand on which band (at which place and which base station) you have a 4g signal but with no Internet connection, install an app like Network Cell Info Lite, LTE Discovery, Net Monitor Lite). I think with Net Monster (all apps are on Playstore) you can even see on the map where is the base station you are attached to
If your phone is rooted, you could use Network Signal Guru that will show you, in case of 4+g all bands you are aggregated to with their signal strengths, base stations locations, etc (apps above would always show just one, primary band):

Ohhh thank you for this explanation.... Someone actually mentioned aggregation to me also. This helps make me clear up how Xiaomi does this and that. Does this mean force selection of network band won't work on Xiaomi devices?

I'm pretty sure that with MIUI 11 there was an option to disable/enable 4+, but on MIUI 12 (12.0.2 QFJEUXM) there is no more that option
I don't know of other options (except to prefer 4, 3 or 2 g), specially about selecting bands
choose band mode

I've heard conflicting things regarding band support on this device.
These are the bands supported by the PFEM10 model, with the bold ones used by T-Mobile in specific for their 4G LTE connectivity:
1, 2, 3, 4, 5, 7, 8, 12, 17, 18, 19, 20, 26, 28, 34, 38, 39, 40, 41, 66 - China
The only band missing is band 71, but otherwise the device has 5/6 4G bands needed for connectivity. The reason I'm asking is because I have a friend who imported the device from Hong Kong to the USA and he says when he plugs in his T-Mobile SIM to the device, he can't get 4G connectivity or any connectivity whatsoever. WiFi works fine, but no mobile data. We already called to try to activate the phone and was told by T-Mobile support "this device is not compatible with our network", even though the phone is factory unlocked and GSM-based.
Am I missing something here, or is there more to the picture than just band support?

Try entering the IME numbers in T-mobiles web site(bring your own device page). When I was researching this(I'm on T-Mobile) some were incompatible. I have the global version and have 4g connectivity but no 5G. HD voice also works even though the indicator does not show on the status bar(it shows in the dialer screen.
BTW..forget about AT&T. They wont support the phone AT ALL! I left them because my Xiaomi Mi 10 Ultra worked fine on 5g until the 3g shutdown. They basically told me tough nuts so I left for T-Mobile.

Thanks for the reply man, I feel like we're the only ones here lol. I found an app on the Play store that allows you to take the first few numbers of a dummy IMEI and it fills in the rest of the numbers. I copy and pasted some variants of my Chinese IMEI version, and none of them works with t-mobile. I found a dummy IMEI number for the international version of this phone and made a few variants, plug them all into T-Mobile and they all say compatible, so looks good. So I'm pretty convinced that the international version will have 4G connectivity from your reports and a few other sources. I'm actually on MetroPCS but I know they use T-Mobile's infrastructure so I would assume it would be the same thing.
Another interesting thing is on Mint Mobile's IMEI compatibility checker, it gives some good detail... I typed in the Chinese IMEI and it said the phone did not support VoLTE, but I type in the IMEI number for international version and it says that it DOES support VoLTE. So my conclusion at this point is that the Chinese PFEM10 Oppo Find X5 Pro DOES support VoLTE but not specifically T-Mobile/MetroPCS's USA-based carrier implementation of VoLTE so it won't work despite the device having the compatible bands? Does that sound logical?
So do you have the options for things like volte and Wi-Fi calling under your sim settings on the global version?

Yeah,I thought more people would chime in on this lol don't see the normal options for either but when I'm on a call, HD lights up and my calls are crystal clear.
I have now owned the PFEM10 in USA on T-Mobile for about a week and my unit connected to my service almost instantly after I moved my SIM over from my IN2025(Oneplus 8 Pro). Everything works fine but no 5G indicator on status bar. I have confirmed using the app "Network Cell Info Lite" that it does connect to the n41 band however and still can get over 100 Mbps download speeds. HD calling works too.
Also, something odd but hasn't really caused an issue. On my old phone, when going into Mobile Network settings, you would find a "Preferred network type" option allowing you to limit the phone connection to 5G/4G/3G etc. but on this phone you do not get that, or many settings for cell data at all, at least in my experience on the T-Mobile network.
I just received a new PFEM10 and after inseted my italian SIM the roaming is with AT&T 5G and hd voice (see attached)
They messaged me that I can use sms and data but no phone call.
I don't know if is because the phone is not registered with them or something else. Also msg. work on T-Mobile.
