LTE speed very different from Nexus 5 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

hey guys, I have a N5 and a SGH-I337M and in the exact same location I see on the speedtest app 80Mbps on the N5 and barely 12Mbps on the SGH-I337M, same server too.
I've had the hardest time with this phone, I thinked I tripped knox, I was never able to use LTE on CM10 so I gave up and switched back to stock (I337MVLUFNC1)
But now LTE is slow and I have no clue why, any ideas guys?
Thanks

I rarely see over 30Mbps on my i337m.... if you want a nice rom, check out Mapleleaf in the development section.... the dev provides excellent support.

So this is a ROM issue?

[Q] Nexus 4 LTE in Canada - Stopped Working

Hello,
I have a Nexus 4, my carrier is Telus. I have had my phone for 3 weeks now. When I first got it, I used the *#*#4636#*#* trick to get LTE on my phone. It worked great! According to speed test I was getting 27mbps download, whereas on HSPA+ i got 7mbps.
In the last two days, for some reason my phone will not work on the LTE network. I get full bars but they are grey. Also, when the connection used to work, there would be flashing up and down arrows on the signal bars. Now, there is only a flashing up arrow (no down arrow).
I called telus tech support and had them reset the connection to my phone, I also bought a new micro sim card, neither worked.
I do not require LTE by any means, but it is disappointing that I cannot figure this out. Has anyone had a similar problem? I spent the last few days checking other posts and there doesn't seem to be anything similar posted. If there is, I apologize, I am a noob, and I watched the noob video.
Take care

Hey there. Fell Canadian (and TELUS customer) here. I live in British Columbia, and I just checked my LTE and it seems to be working. Are you using a custom ROM? What Baseband version do you have? I'm on M9615A 2.0.1700.33. Hope this helps.

Hi,
Thanks for the reply. I am not using a custom rom and we have the same baseband version
That's strange. What part of Canada are you in?

I am in Toronto. I told google that my device makes a buzzing noise (which it does) and they are sending me a replacement. Hopefully the new phone won't have the same connectivity issues.
Did you try changing your APN settings? I know for Rogers customers, there is a specific/different APN to use when you want to use their LTE network on your Nexus 4.
does it work without LTE? if you go back into the settings and change it back to the default, does it work on HSPA+ or 3g?
My LTE works, and is really really fast. download is about 90mbits/s and upload is about 75. I am in Barrie Ontario, on Koodo.
However, the speedtest app will not work, no matter what I do. So I have to use some other crappy app. Anyone else?

[Q] Nexus 4 - Low Signal on T-Mo

Bought my mom a Nexus 4 from the Play Store to replace her Galaxy Blaze (piece of ****) and it loses signal constantly at her house and at work. Just looking for some advice on what to do, as I'm not fairly sure it's a hardware problem.
From what I've seen the phone works perfectly fine and has service everywhere else with good coverage. My mom's house and work never had great coverage (always 0/1/2 bars with Blaze and S2) but she had Wi-Fi for internet and calling/texting always worked; they never lost service completely. Does the Nexus 4 have a lower strength antenna? We got her a new SIM card from T-Mobile and I had done the update to 4.3 while it was on Wi-Fi before we tested it at all.
At this point, I'm not sure whether to root and install different radios and void the warranty, or if it shouldn't be having these issues at all.
Thanks for any advice!
Need a little more info, what region are you located in? How long has this been happening, is it persistent or off and on? I've had similar issues lately in Houston TX. I'm here to help if you need it.

Please review this article http://www.androidpolice.com/2013/08/26/bug-watch-android-4-3-radio-bugs-causing-cell-connection-drops-on-some-nexus-4-handsets-fixes-in-sight/ from Android Police for your problem. It's a bug with version 4.3.
BTW, I just bought a Nexus 4 from swappa and I am also with T-Mobile and currently using Galaxy S Blaze What a coincidence!!!

Ok thanks taodan! That actually sounds like what it could be. I'll see how 4.2.2 works before I jump to any other conclusions.
Hopefully you got a good price since Google just lowered it to $199/$249 on the Play Store. Their price protection is getting us $100 back even though we got it a couple days before price change.
I had the same issue with the 4.3 radio, flashing the 4.2.2 radio has alleviated my problems.

Couple days late but for anyone having this specific issue, the 4.2.2 radio has solved all problems!

[Q] LTE Won't work with OmniRom :(

So I've got OmniRom installed on my Nexus 4 and its the only ROM that won't allow my hybrid LTE radio to actually pull in am LTE signal and it really kind of sucks. I know HSPA+ is fast but here in Columbus, OH T-Mobile hasn't had LTE for long so it isnt saturated at all and its faster than my old Verizon GNex with LTE lol and I really miss it. If anyone has any ideas about how to get my LTE radio working again I would really appreciate it. I've been researching for days and I can't find anyone else reporting the same issue.
Thanks in advance for help!
And to answer and potential questions, I've got the hybrid 33-84 radio and yes, I've gone into the #*#*3646#*#* menu and when I typically test it on other Roms by just enabling LTE Only because obviously if I get service then I'm good to go but it doesn't matter what I do I can't figure it out!!!!

[Q] Slow 4G speeds on Note 3

I recently gave the wife my S4 and got the Note 3. My suspicion that 4G LTE speed with the Note was confirmed when I ran a speedtest. I admit I'm not in a great coverage area, but I get about 14mbs download on the S4 with a Wilson booster. I know that's not much, but hey, at least I can watch a video without buffering. :victory: But with the Note I'm getting about 5mbs and sometimes the signal just drops out altogether and I have to toggle airplane mode to get it back. I'm running Hyperdrive RLS7 4.3 with MJE baseband. I've seen other threads talking about flashing different modems and wonder if that would help. Has anyone come across this issue? I'd hate to get rid of this phone, but 4G is all the internet I've got and these speeds are just to slow. Any help would be appreciated.

The connectivity on this phone is horrible. I've had mine since launch and I travel alot. Everywhere I go its spotty. I believe I'm done with the Verizon and Samsung Combo. They are horrible together.

Thanks for your input guys. Sad to say, I think you're right. Seems like the service with my razr maxx was a lot more reliable and faster. Shame, because this is a great device.
Flash different modem/radio if rooted for improved reception.
Are you rooted? If so, you may consider flashing a different modem/radio in Odin. I am currently running the MJ7 modem/radio on the KK NC2 and am very satisfied. If you are interested, check out the link below.

Thanks, I'm willing to give anything a try. Really want to keep this phone. Had to take the S4 back from my wife in the meantime ... She was not happy.

AT&T LTE Speed

After activating my 6p on AT&T I noticed slow LTE speeds compared to my Nexus 5 (not just speed tests, actual browsing/usage). Contacted AT&T support to verify IMEI and SIM information and they did some sort of SIM refresh on their end. After that I was getting around 70-80mbps speed tests for a few days but now the speeds have dropped back down to 5-10mbs (if that).
I've tried switching to PHONE and PTA APN's and no difference is observed. I am not on an unlimited plan so no throttling should be taking place.
My friend who is also using a 6p on AT&T is seeing the exact same behavior and had the exact same results after contacting support (fast speeds after refresh but slows down after a few days).
Has anyone else been experiencing this issue with AT&T or any other carriers? I'm not sure if this is a radio firmware problem worth reporting to Google or something on AT&T's side.
I'm having this same problem, my s4 was at least double the LTE speed of my 6P, I've been searching for a fix but this thread is the only one I've found so far, I did see VZW post where you can dial a certain number and select bands, I'm hoping someone can share a fix life that for us on AT&T
same here ... very slow compared to all the other phones I have that are AT&T branded and much slower compared to Nexus 5 and OPO. Also every time I call somebody, phone drops down to "H" and then connects the call. No calls over LTE.
I'm having the same issue and lately I keep loosing my lte and seeing only the H for 4g

yeah but i was having issues before the update
I wonder if it's something with AT&T network and this phone. I'll have full bars (LTE) and no service quiet often. I live in south florida, so we generally have great reception for every carrier.
The issue started for me as soon as I upgraded. I tried the older radio as well. I went back to Chroma 6.0 and all is well. I did star the issue in the tracker.
Well I just got off with att and they reset my connection to the network and so far so good. Lte all around. I will watch the next few days and let you all know

I have actually gotten the same problem, after updating my 6p to 6.0.1, I have lost my LTE and just stayed at H.
I haven't done nothing other than updating, I really hope this gets fixed soon, the speeds arent that bad but I am used to having LTE all around
Well I called att this am at around 8am and tight now at 6pm its been solid. They made me shut off my phone and basically set up my phone network wise as a new phone and boom LTE everywhere
Happening again. I reset network settings and boom all is well for two days
I found a recent post on reddit where a user was having issues with the phone connecting/losing LTE. After troubleshooting with AT&T support they indicated the "APN type" setting was missing an entry and in the improper order.
Changing to the proper order fixed his and others LTE issues and so far it appears that it has fixed my speed issues as well.
The fix applies to both nextgenphone and phone APN's.
Default APN Type on 6p = default,mms,supl,fota,hipri
Correct APN Type from AT&T support = default,admin,fota,mms,supl,hipri
Hopefully this helps.
