Use data while in call?

Hady nexus two days. Noticed when I was in the middle of a call I tried using Google maps to locate a place. Maps said I need a data connection. I did also notice next toy signal icon the data sign was gone and a phone icon was next to it. I came from the sgs3 on Tmobile. Is there a setting or an APN that needs to be set? I was in a 3g/hspa+ are. Am on latest 4.2.2 update.

Yep.maybe it was the area. I started the call in a big stretch of the interstate that is only 2g. When I tried using maps. I was in the 4g area but maybe the towers hadn't switched over?

yeah, only happens when you are on 2G... can't have phone and data simultaneously

Correct, data disconnects as soon as you use voice on 2g. :thumbup:

That's what I was thinking but was going to be dissapointed if this phone didn't actually have that basic functionality of a smart phone. Lol.

Is it worth updating Nexus 4?

Hi guys, I just bought my nexus 4. I'm really hesitant in updating because I also own a nexus 7 and when I updated that, my tablet was just flawed from left to right so I ended up downgrading it back to 4.1.2. Also, I hear that there is a way to enable LTE, but that with the new update the LTE function goes away? I would really appreciate to hear you guys' opinions. Thanks!

I updated my Gnex and my Nexus 7 but i won't update my Nexus 4, i wanna keep my lte connection, it's up to you, if you don't need lte go ahead and update.

Even if you do update to the latest you can still flash a different radio which will give you the option to use lte.

Oh ok just wanted to make sure that I wouldn't lose the LTE option. Does the new update have any flaws? Or are u happy with the new update and what are the differences between 4.2.1 and 4.2.2?

I think a lot of us are on the 4.2.2 update. Those who didn't update are of course on 4.2.1 because they want their LTE. I would like to a say a majority of the members are on 4.2.2.
Some folks are still having Bluetooth and WiFi issues. Problems like the difficulty of connecting to their device and the same for WiFi. This is plaguing some users but not all. Just a small percentage. On my end everything is working fine. It's just weird to hear others are having these problems. I never have any issues with my devices. If you want to update to 4.2.2, I strongly suggest you do a super clean install/update.

Oh ok well it's good to hear that there isn't as many problems with the update as there was with the nexus 7. But I am a bit hesitant because I'm on T-Mobile and I hear that they are about to get LTE in my area. I live in Los Angeles.

Lol. I live in NY and I think LTE is available on T-Mobile here as well.
If you want to use LTE, then don't update yet. If 4.2.1 is working fine don't update it.

I couldn't find the 4.2.1 rom on the google website that's why. They only have the 4.2.2 rom.
Sent from my Nexus 4 using XDA Premium HD app

4.2.2 has been better for battery life, at least for me. You should update it. And for LTE you can flash old radio, but might not work with the latest versions of certain ROMs, so do your research on that. I believe you can just do a nandroid for 4.2.1 (not 100% on this)

Yeah thanks for the advice, and your right about the battery life because I feel that considering that the nexus 4 has a 2100mah battery the battery doesn't last long enough. If I can do a nandroid backup then it would be awesome. I'm pretty new to the nexus 4 scene, so I appreciate everyone's help thus far.

anyone have a link to the 4.2.1 stock ROM. i think my speaker for my phone has gotten lower with the 4.2.2 update and i want to downgrade it.

It's the third one down the list on the "images". Use 7zip to unpack the files and flash away!
EDIT: There is the option to have 4.2.2 with the 33 baseband to retain the LTE, however that has caused problems for people so the only official way to make it work with LTE is to flash 4.2.1 with the 33 base.

Random Signal Loss

Hi,
Not sure why, I'm facing random signal loss. Particularly when the phone sleeps.
I'm using Sentinel ROM and Air Kernel.
This has been happening in the past week and my other dumb phone on the same network with another sim card always has signal.
Neither the ROM or Kernel was updated recently.
What could be the problem?

Any chance your Nexus is looking for 3g signal where as your dumb phone is on 2g?

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.

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

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.)
