Carrier Aggregation, needs to be enabled? - Nexus 6P Q&A, Help & Troubleshooting

Nexus 6P supports Carrier Aggregation, does it need to be turn on or is it auto config?

id like to know also,thankyou OP

Where is this documented? The specs of the phone say there is no CA, especially B4-B12

If u have T-Mobile and you flash the old radio you will see that the phone has CA. The radio is the one for using band 12. There are threads for the radio. My speeds Lte increased dramatically when I flashed that radio. It uses CA for b4&12 or b12 & b4.

Do I have lte????

I flashed the latest paranoid android and it has come to my attention that when I browse it changes from 3g to h+. I didn't configure anything ... Does that mean I have late???? If yes, epic

Every Rom you flash won't give you lte. The 3g to h means it's just switching to a different 3g from my understanding. To enable lte, go here Nexus 4 LTE mind you, you have to have a 4g enabled sim card and there had to be 4g enabled on your carrier. It doesn't work with all carriers though

You need the latest radio and boot loader for the latest paranoid android. So if you want to have lte, you have to be on stock with the .38 radio not the new one which I think is .48. Also lte is not available on T-Mobile, besides the one lte tower in las Vegas. So if you have at&t and want lte, go back to stock and flash the old radio.img

H+ is TMo and AT&T's 4G service not LTE. I switch between H+ and Edge (E) in my area on StraightTalk AT&T on a stock Nexus 4.
Stock rom just shows H for all HSPA connections, the rom you have must have more specific indicators built in.

T-Mobile LTE down?

I have had the LTE fix on my phone for about two weeks now and today it is not showing up. Is 4G down in the LA area? Is anyone else having this problem?

I'm over in the IE, and LTE is going strong.
This is really weird. All the APN settings and the radio is still there. Nothing has changed except I'm just not getting 4G anymore
Sent from my Nexus 4 using Tapatalk 4 Beta
Have you rebooted lately? I know if I reboot, then the setting in 4636 changes to WCDMA Preferred. I have to go back and change it to LTE/GSM, then turn the radio off and back on before it will connect to LTE.
Not sure if that is normal, but that's what happens to me.
I just did a factory wipe and I rebooted everything works now. Really weird though. It happened right after I put LTE on my girls Nexus 4 and it's not working on hers right now either. I'll wipe hers when I get home I guess.

I get those speeds on occassion in chicago but that doesn't really even matter. the LTE signal seems to penetrate building better.

I noticed that, it still isn't where I need it to be but it's definitely gotten better.
These are my speeds, not the highest but I'm happy with them! I'm in NYC, btw

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.

[Q] Installed Paranoid_Android on VZ G2 and now no TMO LTE

Like the topic says, I installed the following:
[AOSPA 4.4.2 KVT49L] PARANOIDANDROID 4.0+ G2 [beta6]
And latest Gapps.
Phone works fine, but with my T Mo sim installed the best I can get is HSPA+. I am in an LTE area btw, my T Mob HTC One gets the signal just fine.
One other abnormality, the baseband version in the settings shows: "unknown" but the phone does still work
Lte bands arent the same for vz and tmo

Thats not what I've read on multiple occasions. The device does have 3 (i think) LTE bands (2 of which T mobile uses). Now I might just not be in an area where those bands the device already has are used, this I don't know.
Best I have been able to get is H+
As far as i know, tmobile only uses one band for LTE which is one of the 2 bands that att use... but verizon is on a totally different one...

Right, however regardless of if I'm in an LTE area at my house or not, the phone should still show info for things like: Phone number (currently unknown).
This is the video that explains the process of turning a Vz G2 into a T_Mo LTE capable phone:

Ok. I know here claro pr can show unknown and it still works. Iveeven seen phones with unknown or blank imei and it still works with them...

T-Mobile carrier aggregation problem

I'm having a problem with my 6p using CA - carrier aggregation. Both bands 4 and 12 are available and my phone is only using 12. I flashed an older radio that does not have band 12 and band 4 is very fast data speeds. If I flash the newest radio in the very same location my phone only uses band 12 and I see that band 4 is available using Lte discovery but I get very slow data speeds. My phone is not combining both 4 and 12. Does anyone know a fix and have you ever had this happen to you? I've even flashed factory image with no luck. Thanks

It happens to me all the time at work, it's very frustrating. Usually between 7-9am I'm on band 4 with download speeds between 40-50Mb, and after that it seems to switch to band 12 and stays there all day with downloads speed of between 0.22-1.0Mb down...it's ridiculous
I also notice that it can happen when I reboot. If I come to work connected to band 4 and then I reboot I will reconnect to band 12 and never connect to band 4 again until I leave my work area. I don't know if it's a T-Mobile issue or a software issue...It seems more like a software issue, but who knows.

It seems to be software issue because if I flash a radio for 6p that doesn't have band 12 enabled then I will connect to band 4 and have very fast data speeds. ( LTE)

It might be done intentionally by t-mobile. My fiancee's S7 Edge does the same thing.
I flashed an old modem as well to get faster speeds always connected to band 4.

I think it is because band 12 is the lower dBm signal which is stronger. I've asked for a dev to make twrp recovery flashable radio zips and no one ever did. It sure make it easier to flash radios on the fly. If I knew how I'd make one
