Galaxy s3 i747 No LTE coverage cyanogenmod10 - Galaxy S III General

Hello everyone.
I just wanted to talk about an issue that I've see on a bunch of Canadian S3 running cyanogenmod 10 d2att
LTE does not work. Only 4G. I read somewhere that it was an issue tied to not having an LTE icon; however that was not the case. On stock ROM I get LTE speeds around 18-24 Mbps while on cyanogenmod I only see the 4G icon and can get speeds up to 12 Mbps. How can I get LTE speed on my device?
Another issue is the Bluetooth audio. Sometimes it works in my car sometimes it doesn't. I have to turn on and off the Bluetooth in order for my car to pock it up. Also this was tried on multiple decks and same issue arises.
I hope this was posted in the right place
Thanks.

Hspa+ problem

Hey guys, got my nexus 4 a couple of days ago coming from a galaxy s3, and I notice that I never get h+ like I used to do on my s3,it only gets to H, and the Internet speed of course is slower than it I was on my s3, I'm spending time in the same places I spent before but the speed isn't quite as good, I asume it's because it's only getting Hspa but not hspa+, any idea of why is this happening? Thanks in advance

What ROM are you on?
Sent from my Nexus 4 using xda premium
Depending what ROM you're using. Certain ROMs cant distinguish the difference between H and H+ on the status bar. However, you can manually check via Settings -> About Phone for HSPA+.
I'm using the stock rom, not rooted, I checked and it says HSPA:10 never days HSPA+

The Nexus 4 is a HSDPA+42 device so you should get similar speeds as the S3 or even better with the Nexus 4 (unless you are talking about the LTE variant on a LTE network ). I don't think the S3 in general EVER showed HSPA+ as those stock devices always showed "3G" or "4G" or "4GLTE"
What kinda difference as we talking here anyways? 10Mbps or 1Mbps? Somewhere in between?
When it's saying HSPA:10 that's only HSPA and when it's idling. When you are actively using data it will show HSPA+:15 which is HSPA+ (21Mbps or 42Mbps depending on your carrier).
The s3 was the international, I'm not from the us, and I haven't measured the speed but I feel that it takes longer to load stuff, and it never shows h+ on top, only H :s, maybe it has something to do with the band of the carrier?

Like the guy above said, check manually in about phone>status to see if you're getting H+ (when you're doing something that needs internet). Also try doing a speed test with both phones and see if the results are the same or similar.

Well I started downloading and app and it said HSPA+:15, but it's weird that it dent say it on top, either way I feel the speed is slower than it was on the s3, I will test it when I get home to see what's going on... But it is DEFINETELY not faster

Being throttled while connected to VZW hotspot

I have no sim for my Nexus 4. I tether to my VZW Galaxy Nexus. However, it seems I'm being throttled. While connected I run speed test. It starts slow then jumps up to normal speeds.. 20mbs. When I download or get on the web my speed is very slow. To download a 120mb file takes at least 30 min.
When using my works WiFi, speeds are normal. Downloads are as they should be. It's something to do with the hotspot. I've searched for another thread with this issue and can't find any answers.
I've also tethered my Nexus 7 and laptop to my Galaxy Nexus and speeds are normal. This only happens with the Nexus 4. Any help or ideas would be greatly appreciated... Sorry to add another thread in this maze.

Man, I just can't find a fix for this. Been through many different ROMs on both phones, searched the net and settings and can find no answer. I put an active att sim card in to no avail. Such an odd situation. Unfortunately this is my only access to speeds above .5 mbs at home. Again, any ideas would be great.

I'm seeing the same results. I'm using a LTE xoom as a hotspot, and getting terrible speeds on the N4. Other devices, including the Galaxy Nexus, are all doing fine.
Why would you buy a Nexus 4 only to connect to a Verizon hotspot????

Who said I bought it? It's the only way to get wifi at work. Cant get AT&T or T-mobile signals in the building
I have unlimited data on VZW and LTE everywhere I go. However, at my home, no one offers home internet besides satellite. I get much better speeds on VZW hotspot.
I love nexus devices. I wanted the nexus 4. So I bought one. Luckily however impractical, I can afford all this. T-Mobile and att have no service at my home, so getting rid of VZW isn't an option.
I do now have att and T-Mobile plans. Having an active Sim didn't make a difference. I didn't think it would but I held out hope Lol.

I am having a similar issue with my Nexus 4 (with Tmobile Sim) connecting to my Hotspot on my Thunderbolt (Verizon). When connected to my hotspot, my download speeds are stuck around .5 mbps but upload speeds are normal. The Nexus 4 has no issues at all when connecting to my wifi at home or at work, and other devices connected to my Hotspot have no issues. My friend who has his Nexus 4 flashed to CM 10 (also with TMo sim) has no issues when connected to his hotspot on his Note 2 (Verizon).

Network gsm signal keeps dropping

Hello I have been having an issue where when connected to wifi and on gsm/Lte in the testing menu the gsm Signal drops to no bars and I'm emergency calls only. When I change to wcdma preferred it's okay. When wifi is off its also okay. I have not changed anything for months apart from dling the latest Franco kernel nightlies. I'm on Rogers from Canada. I don't think it's a network thing since when wifi is off I get Lte

Probably a kernel issue. Find a version that works and stick with it instead of doing the nightlies (which are prone to have things break).
It's not the kernel, I put the stock one back on and the same issue. It's been rainy here the past couple days, I wonder if that plays in.

Maybe something to do with how you setup LTE since the phones really not meant to have it. Maybe a good place to look is in the thread specifically for LTE in the General Section, its pinned to the top of the section.

Getting ready for 4G?

HI, the three network in the UK is rolling out 4G this weekend, what rom do I need to flash my nexus 4 with to get it working ???!!....I wan't super fast lol !!!!!!!
I think it's only starting in like 3/4 cities if your lucky enough to live in one of the cities. Also nexus 4 only supports one band on 4g if your also lucky enough for three to be using the supported band.

itll work on the n4 only if its band 4 lte, and no other frequency for lte. and its not about flashing a rom, its about flashing a hybrid radi, having the right apn, and changing the phine info to lte/gsm. there are threads that explain how to do it.
Yes I live in London.....but since updating to the latest 4.3 I can no longer select 4g LTE in the service menu. How would I find out if three is using the correct band !????

for 4.3 the option is in the phone menu, . and you need to ask them what band they are using.
Yes but if I select LTE it just goes back to CDMA ....!? Goes anyone know the three 4G APN details !? What band goes it need to be to work !??? Sorry for all the questions lol
What frequency can the Nexis 4 pick up on Hybrid Radio?

band 4 for lte only. the hybrid radio lets you use lte if band 4 is available.

it goes back because you need to use either the .27 hybrid radio or the .33 hybrid radio. google disabled lte for 4.3, and you cant enable lte in the settings unless you are using one of the hybrid radios.
After a quick search its 800mhz band is that ok !??
So it won't pick up Three mobiles 4G

Anyway it doesn't really matter the 4G chip in our phones doesn't work 100% apparently causes huge battery drain etc

nice rationalization, but not true. the chip works great, everything works. and since switching over to lte permanently, ive been seeing 6-7 hours screen on time regularly. imagine this, when you download things it takes time for it to finish downloading, especially large files. the slower data speed, the longer it takes. the longer it takes, the more battery is wasted. on lte, i average about 30mbps download speed, so downloads finish in seconds. so less battery is wasted. i download 2gb games from the play store in about 13-18 minutes. the newer lte chips are much better on battety than the old days, better than hspa+, hspa, 3g, and 2g.
How can that be possible ? The LTE chip in the nexus 4 has no antenna or amplifier :/ hmm I'm baffled

doesnt need it? whatever it is, you dont hear complaints from lte users here in the states(mostly tmobile) about data signal or data speed for sure. and about battery.
Looks like I'm gonna have to get a nexus 5 then !!! Dam !!!

Battery life is the same with LTE enabled. My N4 has it enabled my wife hasn't let me to it to her's yet and our battery life is the same, but my data is much faster than her's. I get LTE signal with my N4 in the same places as I do with my Galaxy Tab 2. So I would say it works perfectly fine. Yes I am on T-mobile in case anyone was wondering.
3 UK is going to use LTE band 3 and 20 only, so the nexus 4 will not support it (unless Google is going to release a Nexus 4 LTe version, which is pointless because you should get the Nexus 5 anyway.)

Many people are using LTE on their Nexus 4 including me, it only work with LTE band 4.

Question about 4g

Simple question. Sometimes my phone says 4G and it seems at that time the data speeds are slow and sometimes it says 4G LTE and the speeds are normal. So my question is what are the differences? The reason why I ask is because I don't move around and the signal keeps changing between the two both with full signals.

I believe when it says 4g it is referring to hspa, which is technically 4g but not as fast as LTE. It all depends which kind of carrier your ROM is for. On the international ROM '4g' refers to LTE and on my Fido GS4 it just says LTE. I might not have clearly answered your question but I hope I shed some light to it. Try doing speed tests to gauge which one is which.

Lte is faster as you already know. 4g is att way disquising hspa+. Which is like 3g. I think you live in an area with weak lte coverage is why its switching back and forth.
Ah that explains it. I did not know 4G meant 3g on att but it makes sense now. I just think I need a new sim card.
