I live on a fringe of T-Mobile service, and our Nexus 4 are not getting as good of signal as our previous optimus T phones.
I am starting to consider a GSM repeater, but was looking for more details inside the Nexus 4 before doing so.
Looking around in the menus, I go into Testing -> Phone information -> Select radio band, but com.android.phone crashes every time.
My question is, how can you tell what frequency band the phone is connected to, if possible?

My phone crashes too when I tried to go into "Select radio band".
Have you figured out the problem yet?
Thanks.

I also have experienced this. Note: this is an unlocked version from Google. Not sure if that's different than the T-Mobile version in case OP has that one.
Just got reformed from the Church of Apple, so I haven't poked into the root process yet.

T-Mobile one I'd exactly the same except it's sold at T-Mobile stores and is more expensive. I think the radio chip in the soc is not configurable like pass devices. The S3 line might've been the last series susceptible to band change.

I also have the same issues. Has anyone found a fix?
If you are on 3G or "4G", 99% of the time your phone is using bands 1700 and 2100. If you are on 2G it is using 850 and 99% of the time 1900. The reason for the 99% of the time is that the 1900 band is being moved to 3G but such has only happened in a few places thus far.
I have the version direct from Google, but com.android.phone crashes for me every time too. I'd like to just be able to see what band I'm on. I get poor 3G/AWS reception at home, but okay Edge. I was hoping having 3G over PCS with the refarm would improve my reception, since it's the same frequency as Edge and supposedly 1900 Mhz penetrates buildings better. But if anything, the reception seems a little worse on the Nexus 4 compared to my Nexus One.
This the only rom that will let you change that with out a fc http://forum.xda-developers.com/showthread.php?t=2130627

I am in the same boat. I've googled around a lot and tried all kinds of secret codes, but I haven't been able to figure this one out. I even spent a fruitless hour on the phone with AT&T support, but they told me which frequency bands they use in an area is "proprietary information".
HOW TO Flash T-Mobile USA Radio Via Recovery (Needs More Work/Tweaking)
All credit goes to he_stheone64 and his thread located here: http://forum.xda-developers.com/showthread.php?t=2245615
Credit: The War Horse - for telling me the obvious, how to get the radio was listed in the thread above all along
I apologize this is my first stab at development and for any errors you may or may not run into. This is fully expected to work with he_stheone64 method above as the only thing I changed was the radio.img.
This thread taught me how to extract the T-mobile USA radio from my HTC One. Now its time for those in the community who really want to have T-mobile 3G speeds to test this out!
This is for you and you deserve it. As I promised with no more words....
This is how you can upgrade your RADIO without S-Off
1. Download Radio update.zip below and copy to your SD
2. Only an optional step for those, who want to have a Radio Firmware backup just in case
a) Connect your device via USB in recovery and open cmd in fastboot folder:
adb shell
dd if=/dev/block/mmcblk0p31 of=/sdcard/radio_firmware.img
You will now have current Radio on SD as radio_firmware.img
Expected output:
PHP Code:
Code:
~ # dd if=/dev/block/mmcblk0p31 of=/sdcard/radio_firmware.img
dd if=/dev/block/mmcblk0p31 of=/sdcard/radio_firmware.img
153601+0 records in
153601+0 records out
78643712 bytes (75.0MB) copied, 11.826523 seconds, 5.4MB/s
3. Now just flash the Radio update.zip as usual in recovery, reboot your device and enjoy the T-mobile radio
In case you want / need to restore your current Radio backup:
Either you adjust updater script to radio_recovery.img or just do it via adb in recovery:
dd if=/sdcard/radio_firmware.img of=/dev/block/mmcblk0p31
Download Radio from:

Give it a try. International radios have been flashed using this same tried and true method listed in the first post. All I did was add the t-mobile radio and viola! At this point everything is safe and its just the question will the developer/ATT phone let us call using T-mobile 3G
If it doesn't then please let us know and flash your original radios back from the back up in step 2.
my order is still in picking status.

Id love to try it on my dev edition, but i havent switched to tmobile yet. hopefully later this week, and my area has LTE and is refarmed. Id like to see a radio that enables all frequencies, but i dont think that its possbile. at least not yet.
I just flashed it. copied the old radio img, then flashed the zip file.
But I don't notice any difference in radio reception. Network connection changes from E to 3G to H to no service every few minutes just as before I flashed it...
I live in a refarmed area, but my G2 would always have a solid 4G connection in my room. Not to mention the service bars are between 2-3 on the One. I usually get full reception here.

I don't want to flash it as I man return the device (for a TMO version, or maybe an S4/other), but I can confirm the same behavior with the stock radio:
1900 refarmed. Gets "H" sometimes, but never for long. Mostly switches between "E" and "3G". Old TMO phone had solid "H" always. My bars are about the same as before... usually... right now my phone is only showing 2 bars and "G" which must be slower than Edge I guess.
you may get same connection with tmo htc one in your area.

I'm on Tmo with a 32gb unlocked One, so I gave it a shot. I have a SGS2 as well so I know I get HSPA+ here and not Edge, which is what I'm getting now on my One.
I backed up the radio, unlocked the bootloader, flashed recovery, flashed supersu, flashed Tmo radio, did factory reset. No luck, still getting Edge on my One.

so it means either there is no 1700 band in unlocked version or need other tricks to unlock it.

Keeping the solid "H" is just a tmobile software trick. Like all carriers they "tweak" their signal icons and bars to keep the icon on while in range of hspa+ but most, if not all, unlocked phones will show "3g" until you start transferring data such as opening a web page or syncing weather or mail, etc. then it'll show the "H". If youre showing "3g" then youre in 1900mhz "4g" range.
As for you only getting "G" it really sucks but you seem to be getting crappy signal.

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.

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.
Just wanted to share my experience with the new Radio on 6.0.1 so far it is much better.
1) band 12 active
2) better signal switch even when band 12 is not there it now could lock on to edge or other. I get signal now inside basement where I get nothing before
3) I noticed that the phone also dynamic switch to wifi calling now when it got nothing. It did not do this before
So far so good

Volte and HD voice worked on 6.0. I thought that was the norm? It works as well on 6.0.1
Yeah, VOLTE and HD Voice were working from the beginning.
The only thing I have noticed is that my phone seems to take longer to grab signal when I reboot. It shows full signal bars as soon as it turns on but does not connect to data for about 10 seconds. This was instantaneous before so I'm not sure what happened.
Update sometime for the wifi calling to lock on, I still have to restart the phone at time. This aspect still need improvement
Sent from my Nexus 5X using Tapatalk
I agree I think it's better than 6.0 radio. It's more reliable and consistent specifically when going through dead-ish cell zones.
I've also noticed that it waits till the very last second to switch to b12 whereas the original radio that was reflashed would swap between band 4 and band 12 very often. It now seems to wait to about -110-115 dbm to switch
I've had great luck with t-mobile service in the Minneapolis, MN area. We have very strong TMO coverage in the cities so I wasn't too worried about it, however it gets slightly better service than my iPhone 5s did (loaned until i could buy the 5X, since i had just switched from Verizon).
radio on 6.0.1 is great for me. Generally where my parents is, there is zero reception with t-mobile; this is true when if first got the nexus 5x running 6.0. To my surprise after I upgraded the OS, and was over at my parents this weekend, I see the signal bar being 3/4 full with the LTE logo and I was able to use data on it, where as before I wouldn't even dream of making a voice calls
I'm in band 12 Area Tampa using latest build, with LTE Discovery, locks on band 12 but when call is placed it will switch to band 4. So no go on VOLTE Calling for the nexus 5X. Maybe there's a certification process that I'm missing.

I sold my Nexus 5x, but I do have Blackberry PRIV and use it with T-Mobile. In some locations, I do see when device is on Band 12 and placing a call, it switches to Band 4. In other locations it stays on Band 12 when call is initiated.

VOLTE works, or else TM wouldn't have approved B12 for the 5x. Otherwise, in cases where there is only B12, you wouldn't be able to place calls, which is what TM won't allow. The fact that it switches to B4 during a call doesn't mean it doesn't have VOLTE.
Just before call connection is where is switches and I can actually tell the dif between HD calls. B12 works great for data, just not voice. I'm testing it against a T-Mobile note 4, a grad prime and a 6plus. Tried diff APN. No luck
This phone was supposed to come with band 12 support, but I've been in areas that I know get band 12 but it does not pick it up.
I had set the phone to lte only and it didn't pick up any signal at all in the area as well. If that's not the case, can someone send a screenshot showing band 12?

I understand it will use band 12 as a last resort, but the phone would rather have no reception at all rather than accept a band 12 signal. My old phone (moto x pure) would switch to it no problem in this area I'm referring to, but this phone will have no reception at all instead.

Band 12 is a requirement for me before I will consider purchasing this phone. Could you try the LTE Discovery app from the Play Store? Maybe it will shed more light on what is going on.
