[Q] How to optimize signal of my N4 mobile networks - Nexus 4 Q&A, Help & Troubleshooting

Hi guys,
First sorry if I ask a pretty noob question here, i just want solution to my problem.
So, I use 3 (three) as one of available carriers in my country. It really annoys me that sometimes the signal is unstable, and the signal goes very bad while i am in my room. Fyi, I live in the biggest city in Indonesia. Is this a common issue in any of your country? Are there any solutions for my N4 to optimize the signals?
Here is some screenshots of my network speed (using speedtest.net)

Okay then thanks before :thumbup:

If you don't mind having slow internet, select use only 2g networks in network options, this helped me go from 2-1 bars to 3-4 bars

The only solution I've heard of is to try and flash a different radio version:
http://forum.xda-developers.com/showthread.php?t=2087227
Some people report that different radio version give different results, so it might be worth a try - I'm actually considering this myself, since I also have a weak signal when inside at home.

Problem is solved, thanks once again mate!
Now my 2G + 3G signals are much much better than before, after I flashed .54. With .48 I usually have 2G gray bars in my room, now it's always blue, even if I use 3G. Solved right?
Thanks!

NS4g ICS radio signal issues

Anyone having them? My 4g radio seems unstable. It disconnects on its on it at times. More than a few times a day. Also, with 4g on I get a Max of 2 bars. Most of the time its at 0 bars. Like in the pic below. Only when 4g is shut off do I notice that I get to 4 full bars. I've done a profile and prl update. Currently on the ke1 radio. Anyone with the same issues? Fix? Everything else is going smoooooth so far. Running nsx 1.3 with Eugene's kernel. Also I've tried all the other ics roms and its the same issue so I know it isn't the rom itself. I read ics for the ns4g has wimax options. As an ex epic 4g owner we had this and it allowed tweaks for more stable 4g connectivity. I forgot the dialer code **** now I have to call sprint and get my msl :-\
Anyhoo, peace fellas.

NS4g radio Issues
yeah i just notice that too, first I though it was my work building I was in (cell phone signal death trap) but lately I have noticed that my 3g tends to drop randomly and my 4g maxes out at 2 bars also. really didn't notice it until Spotify and Google Music both kept refusing to play music saying I was offline Im running vhgomez36-ICS-NXS-4G
Yeah, my data and wifi seem weaker in general when using ICS ROMs.
yes!! it would show that i had 2 bars with 3g but when i would go to make a call it would just drop out and not do anything. very infuriating!
Although i'm running a Nexus S (non 4g) i9023, seem to be having the same problem. Signal is very weak, and completely drops for periods of times in places where i otherwise got full bars, even the WIFI signals are weaker!!! :O
I have a similar problem of my data connection dropping all together. I would still be connected because i can make and receive phone calls but no data (3g or 4g). So far a reboot is the only solutions.
using AOKP crespo with gb55e9ac kernel
Guess ota is the fix here? :-\

Radios by region

Is there a way to figure out which radio is best to use in your location? Like a US-east radio?
Sent from my MB860 using xda premium
With enough user feedback, this thread may become that but a I think the only way right now is by trying them, give each radio about a week unless there is some major performance issue, doing a few speed tests and deciding which worked the best. Although a superthread about radio performance by region is a great idea, it would just take time and a lot of feedback and managing the feedback to work well.

yes because only att sells the atrix 4g in the US. they will most likely work on tmobile just flash different ones til you get the best results. the radio thread has ones for other countries as well check it out. Atrix RADIOS

Be careful with AT&T 36/37 outside of North America. It may have poor WiFi in Europe. N_100 European is seems to me more balanced.
Most problems with battery loss is due to unnecessary Alarm Wake-ups and Networks Locations (especially in my case).
When I disable Network Locations my battery lasts maybe as twice as longer.
All the above is based solely on my own experience for two days of "radio madness".
So AT&T Atrix's can flash any radio?

[Q] n9105f POOR lte SIGNAL ON at&t

Hi Guys,
I just received my N910F, and I notice LTE does not display when it is connected to LTE signal. It displays 4G instead. That is fine with me, but the problem is I only get 1 bar whereas I get full bars with my 2 S4's. using the same sim cards (Starighttalk on AT&T) and same locations.
I tested WCDMA and GSM and the bars are full scale... only when I am on LTE I get just 1 bar...
Is there anyone else having the same problem???
Many thanks

I am experiencing the same issue. I would like to inform you that this is normal for all US carriers. All US carriers, including AT&T has programmed the RSSL cell tower computers to prioritize carrier-branded devices first before BYOD devices. Therefore, you will always experiencing weaker signals on BYOD/unlocked devices on any US carriers.

That's good to hear, at least I know it is not the phone being faulty. I have been fiddling with the phone since morning, master reset it three times, etc... but where did you get this info? Do you have a link ? Thanks
Here is a very long chat about Note 4's on the sprint network having the same problem as mine... I will update this thread as I find more.
https://community.sprint.com/baw/thread/177615?start=0&tstart=0
That's what AT&T Level 3 technician informed me of. I think this is just another method that carriers use to earn more money by forcing you to purchase phones from them.

sprint galaxy s4 Optimized Lineage Os 14.1 stable 4 no signal issue

Hey , i'm using SPH-l720 unlocked. i'm living outside the usa in Egypt exactly.
I've an issue about my ROM . It's getting no signal even in a area with good signal .
My phone can read SIM. Card company and emergency numbers in it. But can't get signal at all. How to fix that issue.

You need a TouchWiz ROM to activate the device.

Hmm, your issue may be related to mine. What type of unlock did you use? Did you downgrade your modem/baseband? To what version?

"LIT" for 4G - what does that stand for?

Hi guys. Since the other day, every time my phone connects to the 4g network, the status bar doesn't show a 4G sign anymore, but a strange "LIT" sign (screen attached).A Google search doesn't explain nothing about it, so I ask you: what does that stand for? Do I have to worry? Tried GravityBox and Substratum to revert back to the 4G sign, but didn't work.
If this can help, LIT began to show up more or less after I played with ADB to hide my tethering activities from my carrier ("settings put global tether_dun_required 0" from cmd). Nothing changed apart from that, network speed seems the same to me. Stock ROM, 8.1 July patch

Maybe it means "LTE" but in a different language
What language did you set your phone?

My phone is set in Italian, but I've honestly never heard about any LTE translations in my language
I’ve hidden tethering using adb as well, and it still displays as LTE for me.
Maybe your LTE signal is just "lit".

In my opinion it is just undiscovered bug. Guess only flashing stock ROM in MiFlash fixes it.
Or maybe you can ask your carrier or operator about that?

I'm a heavy customizer, I just clean flashed the other day and flashing again and re-rooting bothers me. Guess I'll just keep it this way, as long as it doesn't affect my network performance it's just fine - it even gives some swagger to my phone, as some of you noticed lol
