Samsung Galaxy S4T L720T [Trimode] User Discussion Thread

[joesake]

Thanks for the advice on disabling the Spark bands. I did not mention that my phone is STOCK rooted, so all of your instructions worked fine. When I am at home I disable both bands and I connect to standard LTE and do just fine. The tower near my house is scheduled to be upgraded to Spark in January, so I will continue to play with it to see if it is enhanced early.

According to http://www.deccanchronicle.com/141107/technology-mobiles-and-tabs/article/samsung-galaxy-s4-confirmed-receive-android-lollipop, the S4 exynos is getting the lollipop upgrade. Snapdragon bar based S4s are not confirmed or denied.

We're supposedly finally getting the 4.4.4 update this month if recent reports are accurate...I'd be surprised to see L before March/April.

And now AT&T's version is starting to get it, hopefully Sprint's won't be too much longer:

I had an interruption in voice over wifi for almost a week, I was beginning to wonder if it was going to come back. It did just tonight. I also had a local tower happen to upgrade from 3g to 4g this week. Makes me wonder if that may have had some effect on the login or handover process. You would think that it would purely be an internet based process not requiring a tower at all, but it made me wonder at the coincidence.

The Note 4 is also not connecting to WiFi calling. I think it's a bigger problem.

Like I said, mine's back up and connecting fine again. Just a weird long stretch of no service.

[Galaxyguy]

Looks like mine is back to connecting too. I tried earlier and it wouldn't connect. Someone else posted in the Note 4 section about it too. Maybe they got it straightened out now.

Interesting, maybe there's some sort of processing center that had an outage.

I swear the title of this thread used to say "triband." Now it says "trimode." I still follow this thread because my wife now has this phone (my old phone). Am I losing it or did the title get changed? If it did, why? I'm pretty sure triband is the correct term, not trimode.

Something very nostalgic about 'mode.' Conjuring up memories of my Sanyo SCP-8100, what a beast of a phone for the time.

would it be safe to assume that if

 

SPHL720TWT (as shown on the box label) is the "trimode/triband"

 

then the

 

SPHL720WTS would be single band?

 

Asking since Amazon has the S4 for .01 with upgrade but there's no indication which model it is. I asked through chat and was told the model number was the WTS one.

 

Seems like TWT = T for Trimode with WT for white vs WTS = WT for White and S for Single band

 

 

 

I don't want to hassle with returns through amazon if this is the case and it will help convince me to do the $50 S5 upgrade since I missed the damn $1 one last week.

If it's cheap, assume it's the legacy models they are trying to get rid of.

 

The "s" isn't single band, tri band was an afterthought.

 

If it isn't SPH-L720T all jammed together then it definitely isn't tri band. Simple as that. Anything after that point is cosmetic and irrelevant to the radios.

I added another S4 to my account in June from Amazon and received the S4T model. I wouldn't think they went back to the original after that.

[SturgeonGeneral]

Amazon isn't just Amazon.  It's more like an ebay free-for-all storefront.  You don't always know who your supplier is.

[Galaxyguy]

It was directly from Amazon, not a third party seller, if that's what you mean.

I mean PMG's - the one in question, not yours.  Besides his model number seems to bear out that it isn't a "T".

Nothing in the official specs references SPARK or 720T or TriMode or Trband, or any of the other flags that denote a spark phone.

[jefbal99]

I got three from amazon in the last few months, all triband, all for a penny

[SturgeonGeneral]

Amazing.

[P_M_G]

Guess I'll give it a shot. Worst case I won't activate it and return it right away. As to the specs not mentioning Spark, It seems like they are just using the generic specs from Samsung and not specific references to any carriers.

 

thanks for the input

 

 

 

PS Sorry for essentially a duplicate post as I just followed the link in SturgeonGeneral's text, browsed down and saw the same question asked back in June.

For those left with this device or had it, anyone have trouble roaming? My wife and I both have the S4T and traveled to Tennessee and once we left native Sprint we had no signal. It would not roam at all even though all the settings were in place to roam. I remember the old coverage maps on Sprint stated that when I put this spicific deceive it would not show roaming coverage in certain areas. They recently changed the coverage maps and show the same area ( North Georgia and Western N Carolina ) as areas where roaming is available. Anyone else have trouble roaming?

***I did download the refresh customization app to try and fix it.

I have the S4 720T. quite honestly, I don't ever recall my device roaming. but, I am in a strong Sprint coverage area. everywhere I have driven since owning the 720T...I am in LTE Spark or strong 3G. if my device has roamed, I didn't know it.
