Why is it showing this is lineage os?
How can I fix?
There is nothing wrong. I am sure that you don't have technically a "4G" signal, the usual options in the world are only LTE or... 3G. In some countries (EU included), the providers push to say "4G" when actually the signal is actually LTE.

So just curious, I have this feeling that all 3G connections say H+ on the Atrix. I am at home on an AT&T 3G Microcell and it says H+ on my phone and I know for damn sure the Microcell doesn't support HSPA+ speeds.
Any input?
It will display the H+ on every connection besides 2G (edge).
Probably means HSDPA, which most of ATT's 3G network has (the 7.2 network)

Nope.
The correct answer is: AT&T has turned on HSPA+ connectivity on all towers, even if the backhaul is not there to support it.
So, this means that if you have a HSPA+ "4g" device it will show H+ irregardless of if the tower is actually broadcasting HSAP+ speeds.
Yea but a microcell device doesnt support HSPA+ thus there is nothing to turn on...

Ya, that's not correct at all. There are plenty of user towers (microcells) that haven't been patched or "turned on" for HSPA+ and they're still showing the "H+" in the top.
The reason is because AT&T 3G *IS* HSPA...so instead of saying 3G it just says H.
I need to knew wat means this Sentence
T-Mobile, America's First Nationwide 4G Network Sent by Samsung Mobile
It about HTC HD2 iam in Egypt it means i cant use this device ???
My Best site www.IslamHouse.com
what it means is that tmobile have a nationwide "4G" network setup in the USA, which is bollocks, its not 4G, or at least by the criteria of it. its more like a 3.5G or a Pre-4G it uses HSPA+ which is based on the 3G network but is quite a bit faster
LTE advance and WiMax2 are the only two ideas defined as true 4G, and neither of those is on the market yet.
anyhow, it means bugger all for your HD2 as that only supports HSPA, depending which version of the HD2 you have (which network its setup for) assuming you have had your HD2 working there it will still work there with the "4G" but you wont be able to get the HSPA+ speeds.
Hey folks,
I am currently using an unlocked S4 from Wind Mobile on the Virgin Mobile network. It is technically the T-Mobile variant - SGH-M919V.
In comparison, the Virgin/Bell S4 is the SGH-I337.
My phone usually stays on LTE but it tends to revert to 3G in some areas, but never on 4G or H+. I had thought that the bands were compatible on the virgin mobile network, which brings me to my question.
Does your S4 ever revert to 4G or H+ when not on LTE? If that is the case, I am thinking of trading my Wind S4 for the Virgin/Bell S4.
Appreciate your feedback.
Thank you.
I'm pretty sure the M919 should fully support the 850 and 1900 MHz UMTS/HSPA bands, also you'd never see 3G or be able to do voice calls and texts without them.
I just got my SGH-I337M from Virgin yesterday and it definitely reverts to H+. So far it seems that it reverts from LTE to H+ after the phone has been sitting a while, and then if I start using the data it will kick up to LTE (probably doing that to save battery instead of keeping LTE on all the time?).
Who knows what could be going on with your unit. That is a Wind unit right? Maybe the software is different. One thing I know is that ROMs can show 3G/4G/H/H+ differently. Have you done a speed test while it is showing 3G? If it is true that you are falling all the way down to basic 3G/UMTS and not getting HSPA/HSPA+ then your speeds should be limited to less than 0.5 Mbps I think.
Thanks for the quick reply.
I managed to run a couple of speedtests when not on LTE. And they were around 2 Mbps down and 1.5 Mbps up. I don't think those are necessarily H+ speeds. But it's decent enough. Maybe then the reason I am seeing 3G is because of the way the ROM chooses to display non-LTE connections.
I double checked the supported bands, and it is true that the Wind S4 (T-Mobile variant) not only supports all the bands that the Bell/Virgin S4 does but the additional AWS band as well.
Is there a way for me to force the H+ connection on the phone, just to see that it works? Or should I possibly flash the modem/radio from the virgin/bell ROM?
Open up the Testing Menu, go into Device Info and see what it says for Network Type.
Make sure your wifi is off and hit "Run ping test" as few times and look at what it changes to.
HSPAP:15
HSPA:11
HSUPA:10
If you see these then it's fine, just icons are different.
Solved!
Okay,
I did a few things to verify that despite the phone showing 3G, it is in fact on 4G or H+ when not on LTE.
I went into ServiceMode by entering *#2263# in the Phone Dialer.
I forced non-LTE connections by changing the automatic preference to WCDMA 850 and WCDMA 1900 respectively.
These are the 2 bands that are 4G or H+ for Bell and Virgin Mobile Canada.
Then I ran speedtests to a close by server and got around 7 Mbps down and 3 Mbps, which are definitely 4G/H+ speeds.
Also, following @ChronoReverse advice, I found that the network type was in fact HSPAP: 15 and HSPA: 11 (screenshots attached).
So, in conclusion I can rest my obsessive personality and accept the fact that the phone is in fact capable & is running on 4G networks. It's a ROM thing I suppose.
Or in other words, the Galaxy S4 from Wind Mobile (or T-Mobile) is completely capable of running on Virgin Mobile Canada, Bell Canada, Rogers networks with full support of LTE and 4G/H+.
Embarrassed to say what a small little 3G icon does to a person these days!
Thanks for all the help!
I see in setting - about device: mobile network HSDPA:9
But in status bar - 4G
Is it correct?

Yes; hspa is 4g and LTE will show up as 4g LTE.
Sent from my SAMSUNG-SGH-I337 using xda app-developers app
That's normally.
AT&T tries to hock off their HSPA+ service as "4G" where it is really 3G service. 3.5G (Or 3.75G) if you want to get technical, since regular HSPA is 7.2mbit where AT&T's HSPA+ is 14.4mbit. When connected to LTE it display "4G LTE" on stock roms.
If you switch to any AOSP ROM, they will tell it like it is. Instead of 3G/4G it display "HSPA+". And when on LTE it displays "4G"
Just a ploy by AT&T marketing because Verizon was advertising they had great 4G (LTE), and AT&T's network was very far behind so they got FCC to classify HSPA+ as "4G" so they could advertise against Verizon, where in reality the service is not as great.
On my iPhone it used to display 4G whenever I was connected to any HSPA or HSPA+ tower. The tower at my house was only HSPA (Not HSPA+) as max speed I got was 5mbit/s on full signal. Yet it tried to play itself off as 4G. No AT&T...no...
Thank you for the clarification WoodburyMan.
Hi,
So, I'm interested in getting a cheap 4.7" Android phone to use in the United States and sometimes in Canada. I zeroed in on the Galaxy A3 2017. The model that works best in North America is the A320Y, but so far I've only been able to find it online at some store in New Zealand. Since finding the answer to the question, Will shipping the device from NZ to the United States cost customs fees (and if so, how much)? is a question harder to answer than the question, Where is Jimmy Hoffa?, I've begun considering getting one of the models listed in the title of this thread.
But there's a problem. Those models in the title don't work on US LTE. Actually, according to frequencycheck.com, the A320FL has one LTE band (Cricket/AT&T) and the other models have none of the LTE frequency bands. I wonder if frequencycheck.com is accurate. I'm also wondering if there are other differences between those models. I'm also wondering what happens if I put a Cricket SIM inside these phones. Even though frequencycheck.com says I will get no LTE bands, will putting a Cricket SIM inside suddenly activate an LTE band?
The other question I was wondering: Do I even need LTE if I don't care much about download speed? Maybe HSPA+ or whatever it is will be good enough? If I don't have LTE, will I get less reception indoors or outdoors, or will I get the same exact reception/coverage but just be relegated to 3G/4G/HSPA+ service? What is the benefit of LTE besides data speed?
Finally, which one of these models has the most ROM support? Can they all be bootloader unlocked?
I know I'm asking a whole bunch of questions at the same time. Sorry. I appreciate any help I can get with this!
To answer some:
That website appears to be accurate. Doesn't only list AT&T for a320fl once expanded.
As for SIMs activating bands, I haven't seen it on Samsung, only RRC Release, VoLTE, LTE CAT, maybe individual CA combos. The disabled bands are shown as CAL_DEFAULT vs CAL_PASS. Guess it's like Snapdragon.
HSPA+ vs LTE
The range of 3G/4G is close with the same frequency, but 4G performs better at cell edge (low signal).
Speed (anyway)
Well, 3G is usually given its own spectrum at first, then the 2G is refarmed into 3G. Today, 3G gets refarmed to 4G. This leaves 3G with a small amount of spectrum, it becomes prone to interference. It's bit like multiple tv/fm stations on the same channel number. Other 'tv/fm stations' have to be filtered out by the phone, this lowers the speed. 4G gets some too, along with echoed complex signals, but it gets less.
3G supports up to 5MHz per carrier, 4G up to 20MHz. 3G can have carrier aggregation, so 5+5+maybe 5. Expect up to 2 carriers (not every combo) on 4G, unless a specific SIM is detected in specific phone models. Along with that, 4G can have better spectral efficiency.
If you are going with 3G(HSPA, sometimes called '4G') anyway, you should know that there are these states (usually called fast dormancy) to save power.
DCH = Full speed.
FACH = Up to 32kbps. 4kB/s. Maybe RRC Release downgrade is visible (H+ to H).
PCH = No data.
Anything below is further away from data.
For high performance, keep the speed above 4kB/s, at the cost of battery. LTE has a faster start.
Sometimes, the speed is simply constrained by backhaul, the internet access that goes to the tower.
Thanks. So, to your knowledge, the F and F DS variants shouldn't work on LTE in the United States? I was in a live chat session with someone on Samsung's UK website and she said that the F variant would work on LTE in the United States. I then sent them an email to confirm and they replied with:
As per our resources from our technical review, the following Network is available in our Samsung Galaxy A3 (2017) for the US.
Network
Band: Quad
GSM 850: YES
GSM 900: YES
GSM 1800: YES
GSM 1900: YES
UMTS 2100: YES
GPRS: YES
4G: YES
HSDPA: YES
Works in the US: YES
I replied to ask them why frequencycheck.com lists no LTE frequencies in common for the F variant on AT&T. I'm so confused.
sm-a320f / sm-a320f/ds
According to every other (not alternating) source the LTE band 2 and band 5 is supported in the US (and the entire spectrum of these bands). So, it supports some bands. Check if the signal of those bands (for your mobile network operator) are available in your location. Ask again, specifically for band 2 LTE(4G).
