AOSP LTE - Sprint Samsung Galaxy S III

How come LTE doesn't work on AOSP as it does on TW. I'm in Virginia Beach and it's very usable on TW but can't pick it up on AOSP. Also I'm on CM10.1 M2. Is there anything I can do to make this better?

LTE works fine for me on AOSP roms, it's not as strong as a TW rom but it definitely works.

That's not necessarily true. TW's signal bars depict 1X / Voice, but not data properly. AOSP on the other hand depicts data strength always.
On a side note, people actually use TW? Good grief.

To an extent. Cm10.1 actually displays voice signal, even when an established 3g connection is active. Though it does display 4G connectivity via signal bars.

Anything I could do to get it working? Like it works, it just can't pick it up. When it does, it's just for a second and there's no bars when it does.

LTE never worked as well on AOSP ROMs for me and a few other people since the switch from 4.1 to 4.2. Sounds like there is nothing you can really do about it because you are in a weak signal area for LTE.

I thought I had weak signal, but, I have a stronger LTE signal than 3G, on TW. I was getting -73dBm on LTE:14, again on TW.

Used both and had minor changes, like maybe two or three numbers different ( so like one said -73 and the other said -75)

Ok because TW will only show 1X strength even under status. Can you show me a screenshot of your values in SignalCheck?

Under status on TW the dbm and asu is representative of whatever network you're on 1x, 3g or LTE. The signal bars however only represent your voice signal strength(1x-rtt).

Co-worker Pantech Breakout catching 4G signals better than my Gnex?

So, an older gentlemen I work with just picked up a Pantech Breakout from VZW - FREE after mail in rebate. He had absolutely no idea how to interact with device so I decided to give him a hand. I was actually pretty impressed with this Android 2.3.3 budget buy but I knew how vastly superior my Galaxy Nexus was compared to his. When I was showing him side by side some of the differences between GB and ICS, I noticed he had 2 bars of 4G and I only had two bars of 3G. I double checked to make sure CDMA/LTE was selected and gave it reboot.....NOTHING.
What a joke. Thoughts?
Its just telling you it has a better signal. According to VZW the Nexus just more accurately displays it.

Why wouldn't you toggle airplane mode? It's faster than a reboot.

Good to know.
I guess a more definitive test would have been a speedtest. We'll see what kind of results that yields.

This is incorrect.
The signal strength displayed in settings for most phones don't show LTE - Nexus does, so you won't be looking at the same thing.
Also @OP, please stop comparing bars, the only thing it represents is that 1 bar is worse than 2 bars to its own kind that is also using the same skin.
His Nexus is only getting 3G, not 4G!
That sucks. I would flash the 4.0.3 radios.

I read that the 4.0.3 baseband had 3G radio issues. You might want to flash the official 4.0.2 baseband to see if your signal improves.

You beat me to it. . Basically you must make sure you are comparing apples to apples. You should use the db measurement for signal strength and not bars. You can not currently compare the GNex 4g signal to any other phone because ICS is the on version that can show your 4g signal in db. All previous versions lie.
The issue the OP had with not being able to lock on a 4g signal is a different matter. As the previous poster has stated, the pantech may not have had a 4g signal. Speed test may shed light on this. Personally I have not experienced that yet so maybe an issue with just his phone? If not then perhaps I have not noticed it when it happened to me. I'll try to monitor it more. I sit near the edge of a 4g signal so at home I'm always on wifi. It takes way to much juice to stay locked into 4g at home but it does stay locked. I can kill the battery in about 4 hours near the rear of my house with a mostly idle phone in 4g. I have to monitor it more when I'm not at home.

Oh yeah Anand Tech is definitely comparing apples to apples.. The Bionic is one of the worst phones in locking in and staying on a 4G signal.. There is a reason why the Bionic and GN was delayed. Crappy radios!
The GN would be the best phone out if it wasn't for its signal issues. I hate to be sound like the glass is half empty but it is a shame one must tweak the radio for a better signal. I'm still hoping that the GN is software correctable . I really like what the phone has to offer in regards to development. Only time will tell, good luck GN users!

Where are you reading about the RAZR showing 4G icon while not in 4G? I have a similar issue with my Droid Charge where I will have a 4G icon but no data connectivity at all (not 3G/1X even).

Basically most phones with carrier/manufacturer involved skins will make it linger and display the 4G icon even when its cutting in/out. Mostly because people will freak out if their connection is changing all the time. The handoff between LTE and CDMA is really slow, so they just make it show 4G expecting it to come back to 4G soon when it drops.
The Nexus is showing your actual connection with no sugar coating.

5 Bar signal.

For the love of god, having 4 signal bars instead of 5 drives me insane. If there's a rom or mod that has this can someone point me in the right direction? Thanks!

imo, no point "cheating" yourself with the bars, the signal is going to be the same.
If you have a custom ROM, you may be able to change the bars into -(number)dBm.

Want to know something even worse? Every rom we have, the bars show DATA signal.

I don't use the signal bars at all. I replaced them with the dBm reading in the top right notification bar. Wouldn't you rather have that over any amount of signal bars?

I don't know anything about how HSPA handles this, but for Verizon it's like this:
1X is used for voice. Think of it as "2G"
EVDO is used for data. Think of it as "3G"
You might have 1X signal, and be able to make calls, but have no EVDO signal, so you can't browse the web.
So while you might have 1X signal and can make voice calls perfectly, your phone will show ZERO bars because you have no EVDO and can't browse the web.

This doesn't apply to the GSM nexus though. But its certainly true for the cdma nexus.
GSM nexus has only one signal both voice and data use the same signal reading.

Samsung S3 sprint Signal Problem Anyone has issue ?

Hi i just came form S2 to S3 and my signal is real bad
i use to get 4 bars in my house now i get 2 bars at work i use to get 3 bars now i get 1 bar with S3
I have Blazer rom rooted LG8 modem ?
i still have the s2 and i get 5 bars with S2 and i get 3 bars with S3
Can someone advise me or help me how to get a better signal cause this is killing me
Thanks
My signal is better/stronger with the GS3 than the GS2 was. Maybe it's just capacity grew when the S3 came out and made your area more congested?

thanks but i have my S2 and it pulls 5 bars easy good signal
S3 is half of what S2 is pulling don't know what to think ?? I hope there is no defect in MODEM or ANTENNA in S3
Signal bars on custom ROMs are meaningless. I've only got one bar and I'm still pulling in 1.2 Mb per second. In other words there just as strong as the s2 just not display properly.

Look in settings > About Phone > Status and tell me if the -dBm signal strength is the same on both devices. The lower it is, the better connection to the tower. Both phones may be programmed to display different bars when it reaches a certain dBm level.

The higher it is (closer to 0), the better.
Really. I question this because my s2 never did this good and if you remember was plagued with los as well as just plain bad radio, GPS was mediocre,and Wi-Fi was bad. Honestly a barn door or a flip phone do better for reception. Hell even after the los got fixed it was typical to see 3%t. W. S.

2 bars on S3 is the same as 4 bars ob S2 cause my download and upload speed are very close.

There is no such thing as "correctly" displaying bars. Bars are undefined. They just show whatever the OEM marketers and designers want them to show. We might as well call them unicorns. It is never valid to compare "bars" across different devices, or sometimes even across different firmware on the same device. About all you can be reasonably sure of is that on any given device with a given firmware, more "bars" should represent a stronger signal than fewer "bars."
The dBm signal strength readings are standard units and useful insofar as you understand what they are measuring.
Be aware that on the current GS3, both the bars and the dBm display for RSSI under Settings -> About device -> Status are based on the received signal strength (RSSI) for the 1x CDMA voice/text connection, not the data connection, although that should be similar. And if you ever want to measure signal strength for an LTE data connection, the only place to find that is in hidden DEBUG menus.

Most of us dont have LTE yet. I didnt see the OP note that he was in an LTE area.

"

Forget the bars. The above means that your GS2 is indeed getting better signal than the GS3.
As others have suggested, try different radios (there are currently 4 to choose from). I tried earlier versions, but my phone works best with LG8.

I've always got lte the house with no bars on ics now that I got the ota I'm getting 4 -5 bars which is awesome being my apt sits between two towers. I'm a happy camper.

You know, I've seen a lot of people post about how, with the JB update, they're getting better 4G signal. I don't think we really are. There is a spot outside my workplace where I pick up 4G, and I have a work-provided LTE hotspot. The hotspot shows the same number of bars that it always has, speed tests on each device are the same as the were with ICS, but my LGOG now shows 4-5 bars, instead of one. To me it seems like LG just changed the way that the phone reports 4G signal strength, and nothing else.
Yes they fix the signal bar. I never or rarely had bars but now I do. More than my other old lte phones. A full 4-5 bars I've never seen consistently on this phone until now with jb.

I was always under the assumption on Sprint phones the signal bars were really indicating 1x and not data. Also I vaguely remember Android API not having a real method to display LTE signal strength, CDMA being RSSI and LTE being RSRP. Unless that change recently?

LTE Singal is Stronger on OOS ROMs

Has anyone noticed their 5T's LTE signal is stronger when using OOS ROMs compared to AOSP ROMs? I've noticed this consistently whether at home, at work, or out and about. It's not like those places have a weak LTE signal either, it's just that OOS ROMs seems to be better from a signal strength, speed, and latency point of view.
Edit: I noticed on AOSP ROMs, AospExtended included, the network mode is usually 3G and not 4G LTE, even though the LTE signal is better than 3G and has lower latency as well as greater speeds. However on OOS based ROMs, it is the other way around, and the LTE signal tends to be stronger as well. I'm using the same firmware and the network towers and carrier is the same, so the only thing that's different is the ROM and kernel. I can force it into LTE mode but then the 3G functions like phone calls and text messages wouldn't work because the network carrier doesn't have voLTE enabled properly yet.
It's because OnePlus cheats the signal strength reported in oos. AOSP based roms do not. AOSP roms tell the truth.

Then it's not cheating if OOS actually has better signal compared to AOSP?
Edited and updated OP
I've noticed signal is better as well but i chalk that up to cheating. As for apps performance, haven't noticed anything different.
One major gripe i have is OOS seems to jump to roaming towers and stay on them a lot more than AOSP. On my walk to work, for whatever reason on OOS, it jumps to USA towers every single time, which are across the ocean about 10km away, cutting off my data connection, and causing my music to stop. On AOSP, it always stayed on the Canadian towers in the same city within a few blocks of where i'm walking. I wish there was a way to manually specify what networks to connect to to prevent this from happening.
