Whilst I'm being in area which is 100% covered by lte-a, using the same sim in other lte-a capable handsets (which get a 4g+ lock right away), only the p20 seems to stay only with regular 4g. Is my p20 defective? I already made sure that the high-speed lte is enabled in the menu, and I'm running the latest firmware.

Z0mg, not even one?!?!
Hey, i am on p20 pro and lte_a btw. 4G+ is still available on my Handset.

I've seen 4G+ on mine, but only when roaming. I don't think it supports all the necessary LTE bands.

Hi everyone,
My P9 (L09C432 ver.) cannot connect to 4g even though it has the supported bands to do so. Specifically, I am trying to connect to Freedom Mobile in Canada who uses band 4 & 7. Much help would be appreciated. Thanks!
I have P10 Plus, and im in the same boat. My friend's Oneplus One has LTE. I think this has something to do with Huawei, not the carrier.
there is also a reddit thread
and a screenshot
Hello,
Just switched from a nexus 5x to an honor 9 lite bought from Argos.
I have noticed the 4G signal reception being very poor compared to my previous phone.
I have also installed a tool called network discovery and it shows connected to band 3.
Is there a way to switch to band 20? I'm on EE network.
Has anyone experienced same issues?
Thank you all.
I'm on virgin that use EE not noticed this solid signal and 4G in strong areas

I have the Korean N950N and I would like to try flashing the N950F firmware. My N950N seems to have issues switching between HSPA+ and LTE/LTE+ to the point where sometimes I'll have zero LTE bars, and I get no data, but if I switch to 3G only, I'll have no problems and full bars. I don't think it's the CSC so I'm guessing the N firmware handles the wireless frequencies differently, even though it shouldn't. What's also weird is my G935F (S7e) always has at least one LTE bar when testing from locations where I get zero bars on the Note 8.
How do I create a TWRP flashable firmware package to change the model number/firmware and test that variable? I already know I can't flash with ODIN because the signatures won't match. Also, is there anything else that may be causing this issue? My S7e should *not* be getting better reception than my Note 8, based on everything I've been reading about improved modems.
You might want to check the supported frequency bands of the Korean note 8 and the band your carrier uses. Might be a hardware problem and cannot be solved by playing with software.

The N950F and N950N have literally the same hardware. They support all the same frequencies and have everything I need to connect to AT&Ts network. The only difference is the Korean N950N doesn't have the region lock and "jail" issues of the N950F. Additionally, I am able to get full LTE-A bars and speed in other areas and have no issues.
My problem is at my home I, at most, have one bar of LTE-A coverage. Sometimes that coverage drops to zero bars, and there isn't a switch to HSPA+/3G so I have issues sending texts and accessing mobile data until I either shift the phone and get a bar, or completely disable LTE and use HSPA+/3G exclusively.
Automatic switching between LTE and 3G is the issue, not support for the frequencies themselves.
EDIT: In addition, my SM-935F (S7 Edge) *never* loses LTE reception in the same areas and has never had this problem.
Some providers operate on two lte frequency bands. Perhaps one is supported the other isn't.
Most n950f doesn't have region locking.

Actually, almost all of them are region locked if you're buying for use in the US. And again: the supported frequencies aren't the issue. Even if they *weren't* supported, I should be switched to 3G when there's no LTE reception, which isn't happening. I just get zero LTE bars and no data instead of switching to 3G and slower data.
Additionally, the same exact frequencies are supported by my G935F (S7e) and it doesn't have that issue.
Aah.. american telco.. there is a reason they aren't selling n950f there but the sd variant.
And yes it's the frequency. I saw it somewhere but i can't recall.
Which telco are you on if you don't mind me asking

Yeah, the reason we have Snapdragon is some US Carriers use the CDMA network technology and It's easier to just use Snapdragons + their built in modem as opposed to gluing the Qualcomm modem in with Exynos (which was done only once with the S6 and Note 5 because the SD 810 was so ****ty). Either way, they'd have to pay royalties to Qualcomm for CDMA technology usage. But that's neither here nor there for my situation.
I'm on AT&T. It's a GSM based network and fully compatible. I literally have stated multiple times that I the phone supports all frequencies I need. I have the SM-N935F (S7e) which supports the *exact same frequencies* and I do not have the issue with that phone. My problem is handoff to 3G when there isn't good 4G coverage! It *never* hands off to 3G unless I've got a call active. If I have low reception, I'll just have zero 4G bars instead of switching to 3G. If I manually disable 4G I have full 3G reception. When I go elsewhere with better reception, 3G handoff is irrelevant because 4G is working with full speed.
Just to prove my point: Here is the frequency compatibility table for my International S7 Edge:

Here is the compatibility table for my Korean Note 8
https://www.frequencycheck.com/carr...d-lte-256gb-samsung-baikal/at-t-united-states
All the frequencies, minus one LTE frequency, is supported on both phones. My issue is I have *better* speeds/reception on my s7e and when I have low bars, it actually hands off to 3G where my Note 8 doesn't. AT&T is a fully GSM based network and compatible with the International Samsung phones. I've been buying them for years.
Frequency support is not the issue. If it was, I wouldn't get any 4G reception at all! I'd have to use 3G 100% of the time. I need to solve the 3G handoff issue when there's low/no 4G reception.
Just recently switched back to Verizon from Tmobile and would like to continue using the P20 Pro.
As we know the P20 Pro does not support band 13, Verizon does VoLTE on this band so without it calling is impossible (aside form sms and non VoLTE calling).
Do we have any progress on something similar to what has been done to the Snapdragon phones?
RIP P20
Today, all of a sudden, I see 5G showing up on my HK model G9980. I just did the big update Doesn't feel faster than LTE. Does anyone else know about this?
Has TMOB got additional 5G banks that work in the US ? Did they just switch them on? It means this is now a US and much of ROW 5G phone.
It's Low Band 5G on Tmobile, as you stated not much different than 4G LTE. Tmobile doesn't offer super fast mmWave 5G, only Verizon and AT&T but at this point their coverage is very limited. Since there's not much difference between Low Band 5G and 4G LTE it might be better to stick with 4G LTE as 5G consumes more power. You can check compatibility with your IMEI Number here.

Yes, but the point is the 9880 doesn't have band 260 and 261, and up until today I never had 5G in the US on this device.

It's likely 5G Band N41 anchored to 4G LTE on Band 2. Both of these are functional on the SM-G9980 and utilized by Tmobile.
Can you explain what you mean? I would like to understand better.
I notice there's a developer option called 5G Network Mode (SA + NSA etc). What is that all about?
Wonder why it showed up after the latest update...

NSA anchors the control signaling of 5G Radio Networks to the 4G Core, while the SA scheme connects the 5G Radio directly to the 5G core network, the control signaling does not depend on the 4G network.
It says 5G most of the time now but speeds are essentially the same as 4g in the US. So it isn't real 5G?
OP just got his juices flowing.
?
I've noticed significantly better speeds in Chicago.
Have the new 5G UC Icon
