Samsung Galaxy S4T L720T [Trimode] User Discussion Thread

If you guys remember Ascertion said it's in the Best Buy database but who knows when it'll be available for sale.

I haven't seen Ascertion post in awhile... my Galaxy Nexus has been broken for awhile and I don't know how much longer I can wait.  Hopefully the Best Buy close by me has a GS4 with the big T on it, else I might have to settle for the SVLTE one because I can't afford $250 right now upfront.

I think if you order it online you don't have to deal with the rebate crap and it would be $199.

Still no dice.  I think it's only available online from Sprint.com for the T version.  They're still removing old inventory from current stock.

I had a report third week of December from a Sprint store that it showed up in their database for a very brief time and was removed again by the time of that visit.

 

I haven't been back since I bought online so I have no idea of current status in their database.

Just got some information to pass along.  If you see intermittent LTE connect, they are possibly caused by towers in the process of being set up for LTE.  You will see intermittent connections on them from the GS4T for a few days until the setup is complete.

 

As it was explained to me:

 

===

 

eCSFB is your issue. so far anytime they turn on a new 4G tower it doesn't have this enabled until 12-48 hours after its accepted. so if you want to connect to the newly accepted towers you will need to put your phone into LTE only mode, if you don't want to do that then you will just have to wait until eCSFB gets enabled on the new towers to connect to them.

 

===

 

Since we need eCSFB for the Tri-band version of the phone, we have to wait until that has been activated in order for us to reliably connect to the LTE signal.

 

Here's some extra reading on the subject:

I realize page 6 of the thread is a horrible place for this to be hidden, but it can be hot linked to on the web version and probably via tapatalk someplace.  I'll update it as I find more information.

 

**caution** access and use of these screens is at your own risk

study hard before throwing random setting switches.  They are hidden for a reason.

You should NOT have to hit "dial".  Tapping the final "#" of the trigger should take you to the screen.  If it doesn't, re-check what you "dialled" for errors.

Best Buy on Virginia Street in Reno, NV as of yesterday ALL their GS4 stock was GS4T (when I asked if they had SPHL720Txx they had NO IDEA what I was talking about, but the manager came over and opened the locked phone storage cabinet so I could see the boxes and every Sprint GS4 they had was a GS4T, SPHL720TWT and SPHL720TBK, white and black repsctively).  However at the ONLY Sprint company store in Reno where I'd been earlier in the day yesterday they assured me that ALL GS4 phones ever made had the hardware for Sprint Spark and only needed a software update (they had no idea what they were talking about).  When I questioned this further, they went in back and "asked the tech" and came back with the same story.  Then when I asked to see the actual box, they brought out a GS4, SPHL720xxx and not a GS4T, SPHL720Txx.  So, it's buyer beware, check the model number on the outer box.

It's amazing how inept cellular reps can be. I've dealt with similar reps who had no technical knowledge whatsoever. I would rather they just say they don't know than make up something that's completely wrong.

Just curious, does anyone know if Amazon has the 720T yet?  Their product description is not only horrible inaccurate, but it doesn't even list the model number.

http://www.amazon.com/Samsung-Galaxy-S4-Black-Sprint/dp/B00CEKXJ3Y/ref=sr_1_1?ie=UTF8&qid=1390875780&sr=8-1&keywords=galaxy+s4+sprint

 

I'm just curious.  After a few chat attempts someone finally said it was the original 720, but I don't know if they just said that to get me to go away.

Android 4.2 suggests S4, the S4T shipped with 4.3

 

Sent from my SPH-L720T using Tapatalk

Well, they're also saying it support Edge, HSPA+, and GSM.  It neglects to mention any of Sprint's bands or support for them.  The Amazon page is just a copy/paste from other carriers/international version.  I've seen many places where it'll say Android 4.1 installed but it comes with 4.2 or 4.3 installed.  The people that are in charge of product description just don't understand the differences.

Well, I have had ny GS4T, SPHL720TBK, for just under a week at this point. 

 

I like it and it's overall performance has been good.

 

The BAD:

 

When leaving a 4G LTE served area - it takes a while to acquire a 3G data signal.  Once you leave a 4G LTE served area it generally takes its about 2 minutes and even up to several minutes sometimes for it to acquire a 3G signal for data transfer (during which time you're without data service and the dreaded "This page canNOT be loaded" message pops up).  We have many areas where 4G LTE is not yet up in Reno, NV - and, I'm often a passenger in a vehicle and when it drives out of a 4G served area - no data for at least 2 minutes - so this has been a bit annoying.

 

The GOOD:

 

But, on the other side of the coin, its ability to acquire a 4G LTE signal is dramtic.  It seems to aggressively hunt for and change to 4G LTE when entering a 4G LTE served area (even on the fringe of such an area). 

 

My previous phone, an S3, seemed to be just the opposite pouncing on a 3G signal, even when 4G LTE was available.

 

Calls have rung through easily even when I've been browsing - though of course there's no SVLTE.

 

Then of course there's the cute - sometimes spinning - SPARK symbol added to the top of the homescreen.

I do not want to wish any bad luck on to you, but I hope you have a bad S4T and it can be exchanged for a good one.   The lack of a fast transfer to 3G when LTE drops is a totally undesirable trait.   I will soon be looking for a Tri-Band phone and if this is confirmed on other S4T's, I probably would look at another Tri-Band. I can see it now, you walk into a building with somewhat poor coverage, and you need to use your data for some important reason, and you have no LTE or 3G.  Not good. That is FRUSTRATION.  Nobody needs that.   I can not believe that Samsung would put a device out that acts this way.  It is a very simple task to scan for 3G anytime LTE is not available.

We need to have this verified by somebody else with a new S4T.

Could part of the slow fallback be because the LTE site are 100% positively NV and 3G sites are often legacy so the issue may go away when all are on the same network. This issue did give me another good reason to wait a bit longer to upgrade to see if others have it and maybe other phones too.

There are no legacy sites left in Northern Nevada. All are NV upgraded. Only waiting for backhaul on the 3G sites to turn on LTE.

In Omaha, my S4T has never exhibited any such noticeable access lag (changing either direction) for data.  If the LTE signal drops out, and there is a 3G signal available, it jumps to it without any inconvenience.  Streaming *may* hiccup for a few seconds, but nothing unreasonable.  A page being loaded will instantly start downloading again if a manual reload is triggered.

 

If the phone is using data in 3G, it will not hunt for 4G until it is done with an active data connection on that 3G.

 

If you are streaming or otherwise stressing the 3G connect so it doesn't go idle at any time, S4T will not start to hunt for 4G until the 3G data stream goes idle for a few moments.

 

Once it does connect to 4G, the data can be used practically immediately.

Now this sounds about right.  Your experience is fine with me.  Nothing there that would sound unreasonable. We need a few more users to verify that their S4T works like yours.  If we get that, then there is some unusual situation with the phone or the location of the S4T that will not grab 3G when LTE service drops.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
