Finally got the signal figures for LTE to appear in the bar. I guess this feature has been there for CDMA signals all along. I never realized it because the font is so blurry and faint that I can't read the numerals. This is not an inherent problem. My GS3 displays digits for time and battery level, and I can read those.
-
I tried this new version briefly today on my GS3, stock running current Jellybean firmware. I went to an area with 4G signal, and I had 4G icon in my system Notifications bar.
The app showed the Data Type as "Lte" -- which I already knew from the Notifications bar. Sometimes is showed "Lte Cqi2147483647." This is apparently some buggy concatenation with some random string "Cqi" and Java's max integer decimal value.
But the app's "Lte RSRP" field always showed "null" while I had a 4G signal according to my system Notifications bar. And curiously, the app's screen displayed some dBm value for "Lte RSRP" when I only had a 3G data signal.
None of the LTE connections appeared in the log that was exported. (This feature is what I most want in such an app, because I can always see the basic LTE connections data by watching my stock LTE Engineering screen.) There is no display or logging of the cell/sector IDs that are available in my LTE Engineering screen.
I have not yet tried the feature to toggle LTE signal strength in the bar. (Didn't understand that feature at the time.)
Altogether, not a good first impression. It is called a beta, but it needs work for my device. Also, I assume -- since the app runs on others' handsets not yet upgraded to Jellybean -- that its LTE features are based on some legacy workarounds to harvest the LTE signal strength, rather than on the new standard features supporting LTE in Android's Jellybean API.
-
How do you get the beta version?
-
Has anyone gotten the update through the phone rather than downloading it from the web? I checked for an update, but nothing is coming up. Yet anyway.
Yes, several folks have reported getting the OTA, including my manager. Like other Sprint/Samsung upgrades, this rollout seems to be randomized.
-
For the S3, when connected to LTE if you go to Settings->About->Status is that still measuring the signal of 1x or LTE?
It's shows the 1x signal. The only place to see the LTE signal strength is the LTE Engineering screen. See instructions at the top of this thread.
-
Has anyone received the ota ? I've been reading all kinds of tech websites and it seems like nobody has Received it. I think out of 10 websites there was only 2 people who say they received it.
Yes, users are getting the OTA. But I imagine the rollout will take a while because the update file is about 350 megabytes.
Anyone who is impatient should just download the file and apply it manually according to the link and instructions in the thread above. It really is a non-intrusive, easy and almost risk-free operation for a stock device.
-
I installed the OTA file manually this morning, and only had a short time to test the LTE performance. In that anecdotal test, I found no difference with the previous firmware as far as acquiring an LTE signal goes.
I tried in a place with a marginal-strength LTE signal (about -114 dBm RSRP). My GS3 still won't acquire the 4G signal on its own there, but will after toggling airplane mode. This was also true with the previous version.
-
I just got the Galaxy Note 2 this morning and it comes with jelly bean so does that mean I don't have to toggle airplane mode for lte?
We have not idea how well this device will perform with LTE until people start using it.
Jellybean has nothing to do with it. There does happen to be an OTA just released for the GS3 which has some kind of LTE-connection tweak (a Spring-Samsung thing for that device) bundled with Jellybean. But the tweak is not a property of Jellybean, which is a Google Android thing.
-
There are a couple options. You can get the large update, or the bunch of small, incremental ones. Can't say for certain whether you can flash them on a completely stock device, but I think the answer is Yes:
That's the leaked ROM.
I run stock, with stock updates, and I'll wait for the OTA update.zip file. Typically that is also available for download somewhere fairly soon after the rollout begins. But I don't see it yet.
-
XDA now has the LJ7 update and firmware available for download. The main OS (760MB) is taking awhile to download so I'll probably build a torrent of it and link to the torrent here for anyone else who wants to download it (will be seeding the torrent from two decently bandwidth-rich places).
Is this the leaked ROM, or is it the update.zip file format bit-for-bit that is distributed OTA and can be flashed directly by the handset's recovery update function? The latter is what I want.
-
Yeah same here. Yesterday I took a trip to a 4G area and unless I toggled airplane mode my S3 wouldnt connect to 4G...
Affirmative. I have a GS3, live in a developing LTE city, and have been doing a lot of testing. Sometimes, but certainly not always, it does take a toggle to force an LTE connection or reconnection. Once the connection is in place, the device does hold it well -- down to -115 dBm RSRP or maybe even weaker.
The consensus among those who have tested both the GS3 and the EVO 4G LTE clearly seems to favor the GS3's LTE performance. But the Samsung still needs help. L710VPLJ7 will include the third tweak of the firmware affecting LTE connections somehow. Hoping they get it all the way right this time.
-
This release is finally official. See Sprint announcement here.
The final release version is L710VPLJ7
-
It says update is for "L710VPALJ7". However my S3 says "L710VPL13". Can someone expain?
L710VPL13 is what your phone is running now. The update will upgrade it to L710VPALJ7.

I can't believe the SGS3 is getting Jelly Bean tomorrow on Sprint! WTF HTC?! HTC hasn't even released Jelly Bean on the international or unlocked HOX models yet, which means carrier branded ones have AT LEAST a month or more wait for Jelly Bean. This angers me and I might try what others have said to get the SGS3 with the issues of problematic LTE issues. Arg! Proof below:
That leaked memo posted on Phandroid also says that, in addition to the Jellybean rollout, this version of the firmware also includes "LTE system selection improvements" -- whatever that means. This would be the third consecutive OTA for the GS3 that purports to improve LTE connectivity somehow.

How accurate is net monitor at showing the tower where you are connected?
It is completely useless for showing LTE connections. For CDMA connections, utilities such as this and CDMA Field Test are quite helpful when used in conjuction with the S4GRU tower maps, but it can take some field work to nail that down. See my comment here in the FAQ thread.
Are all Sprint towers to be upgraded to NV?
Yes, except for a very few exceptions.
-
The caveat about the Wilson products is that there is not yet any support for Sprint's LTE band. In a home installation, assuming you have WiFi there anyway, that might not be a problem.
-
There are other devices I believe that don't require broadband you just got to do a little bit of searching on google. I know that they have Wilson signal boosters for while in a car. Not sure about a house one but then I don't see why they wouldn't have one.
See also these other threads on that subject:

boomerbubba I tried to get into the sponsor forum you linked to but it is asking me for a forum password.
You need to become an S4GRU sponsor to access that forum.

Just noticed a week or so ago that apps like CDMA Field Test, Net Monitor, etc are no longer able to get cell tower info like BSID and location. CDMA Field Test just shows "-1" for all those values and of course, isn't able to display the tower on the map. Not sure if this started happening after updating to LI3 or if it's related to the upgrades they're doing to the towers here. Anyone else experience this? I can still get the info in the ##Debug# menus.
I use a stock GS3 running LI3, and CDMA Field Test works normally for me.
-
I wish someone had a google maps public layer with all the towers labeled
You need to join S4GRU as a sponsor. There are exclusive maps here showing the precise locations of all Sprint towers, and other maps showing progress as upgrades are completed and accepted at Sprint. Those interactive maps do use the Google map engine.

New member here. Was bored today and went around Austin looking for some LTE on the iPhone 5. Found a live tower off 183/McNeil (on Technology Blvd) which was transmitting LTE. Got around 23m/8m w/~55ms pings on Speedtest.
I saw some crews upgrading a tower across the street from my apartment near Pleasant Valley and Riverside a couple weeks ago. So far no LTE signal from there, but I hope they light it up soon!! I'm excited...
Welcome to S4GRU.
You might check out this thread over in the Sponsor forums, where we are collecting and documenting such detail about live towers in Austin in a shared spreadsheet. Your contributions there have already helped! (We knew about this tower, but we had not captured the full Cell Identity for this sector. I just harvested that detail from your post for the spreadsheet.)
-
Haha, sorry about that. The tower Im talking about is MI60XC232 in Miami zip code 33144. Funny thing is that that tower was not even in the sites expected to be completed by August; yet there's another tower near the airport which was scheduled for completion in August but is currently dead with speeds of up to 10 kbps and haven't seen any work done on it. Im guessing they encountered some difficulties on that tower and moved on.
But those are too many details for this forum. Details cribbed from the Sponsor maps should be repeated only in the Sponsor forums.

Maybe the iOS solution is manual. Ask the user the number of bars and LTE/3G/. - seems kludgy, but would get better participation than a Cydia solution.

Are you certain that the "bars" display is even based on LTE signal strength on the iPhone? It could be based on the concurrent 1x signal.
Update to CDMA Field Test to read LTE

Further inspection shows that I was wrong here. There is LTE signal-strength data in a few of the records in the log file BSLocationLog.csv, in additional columns that have been added to the record in this version of CDMA Field Test.:
But these values are conflated with the CDMA data on the same records (rows), which I assume were being logged concurrently. But as we know, the CDMA connections and the LTE connections really have nothing to do with each other except timing coincidence. Otherwise, they really don't belong in the same logical record. I presume that the time stamp covers both the CDMA and LTE signals, which of course could be from different towers altogether. But it is not apparent to me what event causes a new record to be written to the log at all. I don't think it is simply driven by timed polling. So some LTE properties that are logged can be parsed out, with big caveats.
The new columns are:
In all CDMA records that presumably have no LTE signal associated with them, all these 5 columns of the CSV log contain the string "null".
So far as I can tell, there still is nothing that logs the LTE cell/sector radios by their own IDs, as we have been doing interactively from our LTE Engineering screens to map against physical towers in field surveys. This remains a major shortcoming of this tool's log. The only identifying IDs present in the log belong to the conflated CDMA identifiers (BSID, etc.). And of course the lat/lon coordinates in each record are broadcast by the CDMA base stations, not the LTE sites.
