Some Questions Regarding Nexus 4 - Nexus 4 Q&A, Help & Troubleshooting

Oh well.

LTE is possible for T-Mobile only and if they cover your area. You can check this thread for a flashable zip: http://forum.xda-developers.com/showthread.php?t=2358931
You also need to be using the correct T-Mobile LTE apn which is different than the normal 3G one, and you need to search for network operator in the settings and join T-Mobile LTE.
This phone support dual cell HSPA which is 42mbps. In the phone setting HSPA is referred as WCDMA, so select that. GSM refers to 2G. Once you correctly flash the LTE package you will start to see options for LTE as well.
I don't use any battery saving apps, but I underclock my phone and limit it to two cores since it feels fast enough. You can do this by buying Franco kernel app, but there are other ones like Semaphore, you don't have to flash any kernels but the app should still allows you some control. I also update to the latest baseband (no lte) and disable data when I can. It seems the screen eats battery so I watch the brightness as well. This phone does eats battery I think the best thing is to buy a portable battery charger or one of those battery case if it's an issue.

Ahh, so it's not possible with AT&T then. I'm maxing at 10mbps here but data drops pretty often.

Also ATT do not support DC-HSDPA, only T-Mobile, so HSPA speed on ATT will be slower as well, depending on coverage of course.

stop going from 3g/HSPA/3.5g/"4g" to Edge

I don't think this was working before the update, but now u can enter the
*#*#4636#*#* command and select WCDMA only to stay on 3/3.5g.
And before anyone asks
WCDMA only means 3g and 3.5g which means if your signal is strong enough, HSPA+/4g
Im just curious where do u enter that code?

in that case, shouldn't it be WCDMA Preferred?.... if you end up in a EDGE... only area...?
also... I thought GSM Auto PRL.... was the best option...

Fair warning... this move will impact your battery life heavily.
gsm auto prl can save u a bit of battery life but usually prefers edge if the 3g signal isn't strong enough.
Wcdma only wont allow for a 3g to edge fluctuation. It will force 3g. Problem is, if your in an area with poor coverage it'll be either 3g or nothing and you may find yourself with no connection at all since the phone wont bring u to edge.
Wcdma preffered is like the opposite of gsm auto prl. It will prefer 3g.

Thanks sheek, I guess my best bet would be to good with WCDMA preferred, since reception is shaky in my area...
I think this might be better since it will waste less energy capturing a weak edge signal in a weak area.
working so far. ill report bat life in due time. i cant see how it would really affect it. i hate when my g2 hits edge. if by not using it because of edge saves battery then im fine with a dying battery. i have spares and extended bats anyway

Yup. That's exactly what I do too.
I have a friend who lives in Philly; one of the best tmobile footprints exist in this city. Wcdma only and wcdma prefer netted no gains or losses except when he crossed and passed Camden new jersey.
Or search "radioinfo" in the market and get the app named network that pops up in the search.

That's not the only difference between the modes.
WCDMA Only will only lock in the 3G signals and switch over if there is no more signal for 3G reception.
-Only use this if you're in a metropolitan area or are covered in abundant 3G signals.
WCDMA Preferred will drain more battery, the reason being that it'll scan the airwaves constantly in search of better 3G signals. You are right about it having a wider 3G signal threshold.
-Use this if you're in a 3G abundant city but not where if you're noticing frequently 3G to E switching as it'll adversely kill your battery.
GSM Auto PRL will shrink the threshold for 3G signals as well as less frequent scans for better signal. Generally E to 3G/H transitions happens on 1.5 to 2 bars of 3G signal, but the phone will remain on 3G unless there is an EDGE signal that is better and thus may provide better data transfer speeds or if 3G/H signal is gone.
-Benefits for battery life but not great when better signal is a necessary. Would not recommend this mode if signal is scattered.
As you can tell from my city in my sig, I have a choice between the three, I went with GSM Auto PRL due to battery life being of importance to me as I'm not necessarily next to a tap in 8 hour gaps.
Hope this helps better than my original post.

confirmed xxxxxxx
I have never even touched an HSPA+ connection and I live in an area where it's apparently abundant.
Switched SIMs for a newer one and still nothing. I was told to wait for the 2nd OTA that's coming out by the 8th (And I'm still calling BS on that)
Why in the hell would they push out 2 different OTA's in 1 week for a single device?
I'm hesitant to do this because I don't know if it is my phone being flakey or the actual area. According to TMobile's data coverage website I am in the middle of a massive solid high speed zone... but I constantly flake to Edge.
I don't want to change this setting and it cut out on me entirely, that it may be the actual area. But I guess all I can do is try :shrug:
The one thing I've noticed about the phone is that signal drops when holding it to use the keyboard, if this information's any help.
I found I was hemhoragging battery at some point with 50% no signal according to cell standby. But it wasn't caused by selecting WCDMA only - i am bathed in hspa/umta. Instead I turned on airplane mode while plugged in, waited a bit, then off, then unplugged. Then restarted phone to recovery (clockwork), wiped battery stats, and restarted. Running fine now.

Why is my LTE device displaying as HSPA+?

Hey guys. I Have a Samsung Galaxy Note 2 (SGH-I317M) and for some reason it fluctuates between HSPA+ and 3G signals rather than LTE. The device is originally locked to Rogers but I unlocked it and am now using it with MTS. I am running on jelly bean 4. 1.2 and CleanRom 4.0.5. Anybody have any ideas as to why I'm not getting LTE?

Yes I'm getting fast speeds but I can't help but wonder why this is happening. I mentioned that I'm with MTS so I'm not sure if that's what you're looking for. I live in Canada so it's probably not familiar to you. They just started carrying S3's which are running on their LTE network and they show 4G at the top of them when activated rather than HSPA+.

It is either the towers or your phone isn't compatible with the bands of LTE (there are multiple bands like there is with UTMS).

I'm pretty sure it isn't the towers cause my friends iPhone 5 is running off LTE and he live about 5 minutes away from my house. I've also been at distances one minute away from his house and did not pick up LTE then either. I don't know much about bands or frequencies but my carrier just launched the Galaxy S3's and they run off LTE and I'm assuming the Note 2 has the same hardware. S3: 700 (Band 17), 1700/2100 (AWS) MHz , Note 2: 700(band 17) 850 AWS 1,900(band 2). I'm clueless as to what those numbers mean but i'm guessing the important thing is Band 17, right?
Try going near his house then. Or have you checked the network settings? You may have to flash something.

I have to no avail. I had a friend try to help me out over the phone with network settings and his phone appears to have a setting that mine does not. When he goes into settings > wireless and network more settings > mobile network there is an option for him to toggle between LTE, HSPA+ etc. My phone doesn't have that for some reason. All that's listed is Mobile data, data roaming, Access point names, and network operators. Nothing to toggle between networks, which is probably what I need to enable LTE. I have no idea why that setting would be absent from my device. My friend was using an S3 on the same operating system as me btw.
From what i can tell it's the frequencies . The frequencies your device have seem to be different than the frequencies the s3 have on your carrier. If it's not that then you can check your apn settings.

What model is your phone, and what model is his phone. You said you brought your phone from a competing carrier who is likely using alternate frequencies that your phone might not be picking up either due to hardware or software limitations. Without knowing the hardware, and where it came from in the first place, we can't figure out what frequencies your phone is looking for and can't answer your question effectively.
download an app that will show you what is the type of connection you are actually on.
I think that maybe its the matter of incorrect icon.

LTE not appearing in notification Bar

I saw LTE yesterday in my notification bar, and that was the first time I saw it in 2 weeks. I always have 4G, but I believe that's HSPA+. Anyone have anything similar, and how they would fix it?

Maybe there are issues with LTE in your area? If you didn't change anything on the phone I would reboot it just to be sure but it's probably a coverage issue.

HSPA+ is H+, not 4G. Test your connection speed if you're unsure, anything over 10mbps (especially for upload) is most likely LTE. I get around 24-36mbps up here in Canada.
Edit: Ah, that might be different for each carrier then. I definitely get H+ when I am on HSPA+.
8mb/s. On download, I don't believe those are LTE speeds, and if they are they're pass poor.
Also, never seen H+ on my GS4, so I think 4G is HSPA+.

On the AT&T version, when on LTE, there is a small print "LTE" under the 4G symbol. The term 4G has been abused so much, God knows what it means on any given device.
I`ve got the rogers one and it says LTE when theres LTE and 4G when there isn`t.
Check your apns and make sure its ltemobile.apn set up ?

I think it might be a radio issue with the stock ROM. It was the same on the S2 Skyrocket, some radios worked better than others. The Radio I had on my S2 when I switched over to the S4 showed LTE in my area constantly. Previous radios on that phone were hit and miss...some a lot better than others. I guess we will have to wait until the BootLoader is unlocked (for AT&T S4s) and other basebands (radios) are released until we can test and see which one works better in each area.
My S4 has a pretty good connection now, but it too shows 4G where it use to show LTE. Like I said, some radios do better than others when handling LTE connections.
So apparently the representative lied to me and said that I would have LTE, but my region doesn't support it. That's awesome : /. Thought it doesn't explain why I had it for a brief period. Maybe it came from a tower with LTE. Weird.
Well, This things going back unless a representative can give me a decent deal : /

Are you positive that your area doesn't have LTE? Just because the phone is capable of having LTE doesn't mean you are guaranteed an LTE signal. You have to be within the LTE broadcast area and, your phone's modem (radio) has to pick up that LTE signal. Like I said before, the phones radio has a lot to do with it. Some just handle LTE connection (and all connections) better than others. Radios are flashable, but the bootloader has to be unlocked, with custom recovery installed and different versions of the radio have to be available before Devs can make them flashable. Some will do better than others. It's just a matter of trying them when they are available.

[Q] LTE preferred

I have huge LTE issues. The coverage where I live is amazing, but my phone will not prefer LTE no matter what I do. Does the phone software just suck or is there something I can do?
LTE only - works, but then I cannot make or receive calls. All other modes will prefer 5.9 bars of 3G over 5.8 bars of LTE. Which doesn't make any sense.
Btw I am on CloudyPro II but I don't think it is a ROM issue because I never had had the phone prefer LTE even though I have almost max LTE everywhere.
I have also tried with fast dormancy enabled and disabled. It makes no difference.
Is there a way to make this phone prefer LTE?
Same problem here. Even though i got 4g on my place, it will connect on edge or 3g. Sometimes i got no signal at all. I dont have thos problem on JB. Im on rooted stock KK international. Is this a kernel or baseband issue?

Hmmm... I had the same problem on JB stock...
Another thing that I noticed is that if I for instance set this phone to LTE/GSM/WCDMA it will go nuts. Sometimes changing between H and 3G almost every second. Just back and forth.
It is almost as if this phone will poll the network several times each second and then prefer the strongest signal while completely disregarding data speed.
First, why are creating new threads when already exist similar topics? Do you read old topics? Maybe it has contained answer

And what could it possibly do? You prefer it to connect to some 5miles fay away LTE cell only if it's speed is faster but your modem will then constantly drop packet and reestablish connection to drain the battery? Or should phone grab a nearest and most powerful signal from 3G cell?
And third, wait for Kitkat, it contains a newer 190084 baseband, maybe it will relieve your pains
Then again, why do you complain here instead of going straight to you operator office? It surely is their fault to tweak their cell wrongfully. We can't change their settings

I have tried with different basebands and in case you didn't read my first post I have full LTE signal (6 of 6 bars) if I force it to pick LTE only. If I don't, it will pick 6 Bars H/3G.
I have also tried many different ROMs and I have checked the settings of the Sim card. It is set to prefer LTE.
Btw, did you read the last post in the thread that you linked to?
With LTE i get a ping of 34 ms and 15/5 Mbps. But the phone will pick a HSDPA connection with 47 ms ping and 6/1 Mbps.
And I am on the stock KitKat baseband but like I said I had the same issue on JB
If I force it in my office downtown I get up to 70 Mbps. And as soon as I switch back to default settings (if I boot) I go back to good old HSDPA if the phone is in a good mood. Otherwise I get 3G.
Sent from my LG-D802 using xda app-developers app
I have the same issue, I don't get why WCDMA preferred exists and not an LTE preferred (in *#*#4636#*#*). I'm running stock everything, only thing I've done is rooted, and I'm updated to the lastest firmware with Knockcode that T-Mobile pushed out.
Best way to discribe it is the phone gets "stuck" on whatever band it falls on. If my LTE is weak, it will fall back on 3G or 2G and just stay there - it seems like networks aren't prioritized. The phone should (in a perfect world) look for 1) LTE, 2) WCDMA, and then 3) GSM in that order and only pass one over if weak or doesn't exist, and should it pick up a higher ranked connection it should switch back. It seems the LG G2's just don't... If it falls back on 2G it's perfectly happy staying there until force it back to something else (default mode LTE/GSM/WCDMA) and it's rather annoying. LTE only is viable only when T-Mobile enables VoLTE on the G2's, but as of right now it stops all calls from happening, and I can't even change my phone to only use LTE/WCDMA, because where I work we just got a tower upgrade to LTE and they took the 3G offline, so calls still won't go through since it has to fall back to 2G.
I'll give Samsung some credit when I had my S3 and S4 on AT&T they would always follow the pecking order of what I stated above (in a perfect world) and I never had an issue, but the G2 blows the S4 out the water in performance in my opinion.

Phone keeps switching between 4G and LTE.

Received the phone today. It keeps switching between 4G and LTE in my home. When I walk around the house, it changes constantly. It might be LTE in the living room one minute, and when I circle around and go back there, its on 4G. Does this all over the house. I am two blocks away from a TMobile tower. My Samsung Galaxy S6 stays on LTE. Wonder what the problem is? As of now, its a deal breaker for me and the phone might go back unless there is a satisfactory solution.
I also have the same problem. It always switches in SIM card status between HSPA and UMTS like it has some kind of a bug. Wifi connections works fine, can make calls and SMS, but the big problem is that I can't connect to the Mobile internet. Please can someone help because this is really disappointing.
---------- Post added at 09:48 AM ---------- Previous post was at 09:35 AM ----------
Also this constantly switching and searching for network is draining my battery very fast. So I need to switch to 2G to stop the consumption.
I have the 6gb Version and the Chinese Stock Rom and with Tmobile i got 4g and in a City area i get 4g+ but it always works. Do you have a Shop Rom installed.

I don't know which Rom is in my phone, but I think it's Shop Rom because I received it from Honorbuy.com. My phone model is LEX720 6GB ram & 64GB storage.
mine ( dual sim, 6g/64g) was initially from the shop and it had customer rom. but the 4g was very stable. however, i still flashed the factory rom 017s . but with either rom, the phone have been working fine on 4g network.
Mine does 4G and Let switching too. Seems to prefer 4G and kicks up to LTE if needed based on demand. 4G has a theoretical speed that no provider even dishes out that I know of so I wouldn't worry about that. Battery drain could be an issue, but doesn't seem to hurt mine at all (US version on T-Mobile in Dallas). In fact I suspect it does that to save battery, trying to go with whichever is strongest. Total guess though.

I manage to fix data connection by setting the real APN address. Now 4g works well and there is no switching.

How do u get the real APN number. I am on T-Mobile
LeEco Pro3
When you guys see LTE go to 4G, do you see a little + sign behind the 4G icon? If so, that's normal. It's indicating that you're getting TWO simultaneous LTE connections at once (or in other words, Carrier Aggregation is active). Try doing a speedtest and you'll see pretty quick speeds. It's one of the first things I noticed when I got mine.

You should ask on T-Mobile to give you APN number. I got it from my own operator.
I might be wrong here, but isn't LTE and 4g the same thing?
or is it like HSPA+ and 3g (which is not the same thing)
i get 4g everywhere i go, it never changes to 3g or HSPA+ i can't really complain about that, i do however also live in denmark with GSM
I had to change the APN on mine too. Kept going between 3g 4g and no service.
The new ipdate fix this problem. The switch between 4g and lte. Now its lte every time.
