T-Mobile weak LTE - Nexus 5 Q&A, Help & Troubleshooting

Ever since Ive had my nexus 5 Ive noticed weaker lte signal on t-mobile. I have a nexus 4 that has the .33 radio that i flashed and i get lte in more places & better speeds. Both are using the same t-mobile APNs, for example on my nexus 5 half of my home I get HSPA+ and on the other half I do get LTE i guess I'm just in the middle of two towers that reach me. On the nexus 4 though, I always have LTE In my house and In more areas where the nexus 5 doesn't. I then later flashed the cataclysm rom and thought maybe it would help but nothing, I did find a setting within cataclysm to force lte always on and I get even more LTE service than on the nexus 4, but it takes up a lot of battery. My issue is Im back on stock KitKat and dont have that feature and T-Mobile LTE is just weak. Is it just my nexus 5 or have other people expirenced this too?

Have you tried flashing different radios?

I'm located in Forest HIlls, NY On KitKat 4.4, I usually get 3-4 bars, indoors/basement. After updating to 4.4.2, I still get 3-4 bars. Like real estate, it's location, location, location.

Do a search for EFS and Modems, there's a thread that has a link to all of them. Some have said earlier radios like from 4.4 get better signal. I'm on 4.4.2 stock radio and didn't see any change from one to another but that's just me. In Brooklyn and Manhattan NYC mostly btw.

But there's sparse evidence any are better on LTE specifically. In theory, the latest should be the best. I get 4 bars LTE and 30Mbps d/l, yet get 5 bars H+ and 12Mbps d/l...so clearly despite a lower overall signal strength, my download performance remains perfectly acceptable.

Kernel And radio Combo Question......

Whats the best Kernel to use with the i727UVLE1 radio? Im on stock 4.0.4. Using T Mobile on my Unlocked Skyrocket. Im trying to get better signal bars. Mine is 1 to zero most of the time.
Just wondering...does different ROMS help increase the bars? If so...whats the best combination that somehone has while having 3 or more bars of signal constantly.
By the way..mine is showing 3.0.8 in the about phone.
Kernels and roms don't increase signal strength that has has to do with the radio.

Man...what can i do to increase my signal bar if you know? I see the 4G...but 1 or zero bars. I did a reformat 2 hours ago thru odin. It had the wrong radio because i had no 4G or edge...BUT...the signal bar was all the way FULL. In my room..where its never full. That makes me thing my room IS capable of getting the signal. But what can i do...tweak wise...to get the bars high?

You could try flashing some other radios that might do the trick.

I tried the Blaze...which people say is the best. Gave me 4G...but 1 bar of signal. Then now i have the i727UVLE1....4G...but 1..maybe sometimes 2 to zero bars of signal. I mean...there has to be some tweaks that i dont know about. In the settings or anything. Ive only tried those 2. I see a KiD radio....same base..T989...isnt it all the same...just different people uploading em?

I'm not sure if they're different. The area youre in may not have great coverage. Ummmm you could try some other T-Mobile apns if there are any. Not sure since I don't use mine with tmo.

It has to have good coverage. When i put this sim card into my old Slide phone right now...i get 4 or 5 bars. With a 3G symbol. Also...when i factory reset my skyrocket a few hours ago...all my bars were FULL. I mean perfect...but no 4G. Because the radio was wrong. So when i put the radio i had in it before....4G came back...but so did the suck signal with 1 bar. So i know this area CAN get good signal. I need to know what some people on here are doing to get it. What combinations to use and stuff. Im on stock 4.0.4.
Can this ROM:
http://forum.xda-developers.com/showthread.php?t=1763195
[ROM]SKY-ICS 4.2F6-2.5 (8/2) (UCLF6 Base) AT&T-OFFICIAL ICS.PROJ MARGARINE, W/ G-NOW be used on my skyrocket unlocked to T mobile? Or is this radio in here NOT for T Mobile?
[Edit] See,,right now this second...i just installed the 4.0.4 tar again from odin. It has 5 strong bars of signal right now. But no 4G. meaning the radio in there is wrong. Its showing i727UCLF6. Which is (I think) the AT &T radio. I have a T Mobile sim in it unlocked with TMO. Any radio i add from here...will make my signal go down to 1 bar. BUT...it has 5 strong bars now. Man..wish there was a way to keep those bars.
Sounds like you're in a good 3G area...but only borderline 4G area.
I travel constantly & have encountered this many times.
So..shouldnt i at least have bars with a H or something? Bars are 1 or none. Weird. I flashed thru odin 1 hour ago. Got done...5 bars strong. Filled. But no 4G or data. Had put in the right radio. When i did....4G and data came back...bars gone.

Can you share what rom and kernel you are also using.
I experience the same issues as DJR0D. The blaze radio gets me worse signal, I lose about 4 bars. This was with sky ics and stock kernel.
Right now I am back to the att modem since I need good call quality. It might be a placebo, but I think the calls sound worse with the blaze modem.
No one can help you pick a modem. Its relative to area and device. Flash compatible modems until you get the "best" one for you. Locked

Stock ROMs don't show the + ... So it may well be connected to the highest

Really I thought it might be the case I hop so , is there a way of testing ?

Well, you could check your speeds and see if they line up with what you expect for HSPA+.
The most definite way is to start a file downloading (one that will take a few seconds) then go to Settings -> About Phone -> Status and look at "Mobile Network Type." HSPA+ only kicks in when you're actually transferring data, hence needing to set up the download.

Just do speed tests I guess. See what others are getting. Compare?

You may see it fluctuate and go to 2g when data isn't being transmitted.
Thanks very much your right the apps says h+ .

Phone loose signal about 6 times a day

Hi all,
I got my phone 5 days ago and since then, it looses signal about 6 times a day in places where there is full signal.
I used to own Galaxy S2 and never had this issue before.
I'm using the same carrier and living in the same place so the only thing that has changed is the phone.
I was wondering if it's a known issue, if there's a fix or should I RMA this?
Thanks!
Happened to me until the updates. Are you on 4.4 still?
Team Nexus 5 sucks
Nope, as soon as I got the phone it was on 4.4.1 and then upgraded to 4.4.2
Same thing is happening to me, and from what I've Google'd, heaps of others as well.
Hoping 4.4.3 (or whatever they will call the next one) will fix these issues. I switched to a new carrier, to get the Nexus 5 (I could've stayed with my old carrier and got it, but I was unhappy with them). There is so many issues with the Nexus 5 and my new carrier, its not even funny.
I hate it when my phone LOSES the signal.
It still happens to me once or twice a day. Turning on airplane mode for a few seconds fixes my signal.
Team Nexus 5 sucks
Happens to mine constantly. Pos.

With what can I compare it to? The way I was able to recreate this is when switching to 2G from 4G or 3G

Compare your APNS to your network standard APNS. Simply Google that and you should be able to find it. I would Google it for you but I don't know your network.

LTE issue

Just got my Nexus 5, coming from a Samsung Galaxy S 3. With the S3 I used to see LTE speeds around 25mbps, as high as 50Mbps when right next to a tower. Now with the Nexus I barely get over 1Mbps, what's the deal. Do I have to change something in the settings? My device says LTE and my signal strength is about 88-89 dbm.
Thanks for any help.

sounds like its an apn or on att side.
Yes I think i saw something about APN setting on Nexus a while ago. I'll see what I can find. Or if you have a link that would be cool!

Its an APN make sure its correct and your account is provisioned properly to that device

Followed the APN settings here. http://forum.xda-developers.com/showthread.php?t=1434995. It seems my APN settings are correct. I wonder if something is going on with the towers. I live in New Castle Delaware. I'll be going to Philadelphia later I'll check and see if I get the same results.
Problem solved! I didn't do anything special except put in a bunch of apn's that didn't do anything. Upon going back to original APN and doing a bunch of reboots and airplane mode it just started working. Speeds are very normal for my location.

N5 and sprint network handover

After the latest S5 announcement I'm now ready for the n5. I am coming from S3 on sprint and for the time being I will stay with sprint. My question is...with Samsung s3 if I install a ROM any ROM CM for example the handover between LTE 3g 2g is sluggish I believe its because of some proprioty software (though I am not sure) is this an issue with the n5? Basically is this CDMA/LTE problem or Samsung?

Really nothing

Its a Sprint problem... Depends on the tower... Sprint used different hardware/contractors.
Sent from my Nexus 5 using XDA Premium 4 mobile app
I understand that but the question surrounds the handoff when there is a custom ROM like CM. When using TW its an non issue. So my question is will the handoff be okay with N5 and CM because the N5 doesn't use the propriatory software Samsung does.
Sent from my SPH-L710 using Tapatalk now Free
The short answer is yes...just not as bad..
Here is my experience:
I came from a Samsung galaxy nexus that I had about 4 different Roms loaded on. I could never find a 4.4 ROM that would do a good job on LTE/3g handoffs. My favorite ROM ended up being the Avatar 4.2 ROM.
With the gnex, I would be in a known 4g area but it would show 3g until I would cycle the airplane mode.
When I moved to the Nexus 5 three weeks ago, I was hopeful those issues would be over. Right now I'm rooted with the boot loader unlocked but running the stock ROM.
So. far I've tried 2 custom Roms but keep coming back to stock. I still notice the slow radio handoff but it is less frequent and not as often....but still there.
I hope that helps.
Yes it does ty.
