Samsung Galaxy S8 & Dual Sim/Duos


Recommended Posts

People have been saying HPUE has not made of a different. It has nothing to do with your city. It's all about the device.

All of you are misinterpreting what HPUE is.   It does not increase RSRP levels as that is the signal it receives from the eNB.   Hpue increases the TX connection to the eNB so that it is able t

From limited testing, B41 stays connected on the GS8 at a -110-115 B41 area whereas the Pixel and GS7 was mega band swapping between 41/25/26 at -115 to -120 range.    IOTW, HPUE seems to work. 

We are holding an S8 raffle.  We might be late to the party on this one, but, if you already bought one you probably could stand a second one in your household.  Enter early and often and help support

first thing to do is change the device band priority, for some stupid reason it's set to scan 25 first. That makes a big difference.

I did. It shows band 41 first.

I have a question regarding the Sprint Galaxy S8. I have my roaming settings all turned on and all my roam alerts turned off. However, when I "Update Profile" on my phone, all those changes I made reset to the default. Do you guys know why or how I can fix this?

That always happens, just the way it is.

To clarify, when you "update profile" you are doing exactly that, resetting your settings to default.  May I ask why you are changing the settings and then doing an update profile?  You shouldn't have to manually update profile, really ever unless you are having device / tower issues...  There is no workaround.

Hmm, I'm usually not doing a profile update. I think I was mainly playing with my S8 as I just got it. I also saw it update the "profile" on it's own before so just curious. If I remember, I don't think it was like this on my S6. It stayed on the setting it was before. Thanks for your input :)

The unlocked GS8/GS8+ is now available for pre-order from Best Buy and Samsung.  Is anyone going to go with this version?

I want it so bad -- but I already bought a Sprint version and I don't know how I can justify switching it out since I can't return this. I'd have to sell it on eBay or something. I'll probably end up sticking with the Sprint version. Bah!

I want the unlocked version also, but I will PROBABLY get the Sprint version since they get more frequent updates (from what I've heard).

I used Samsung Pay for the first time today. Honestly it might have convinced me to switch over, at least until more payment terminals adopt NFC. I went to CVS (which for some reason doesn't allow you to use Android Pay) and decided to try Samsung pay instead. I held it by the card reader and it recognized my card just as fast as NFC does.

Samsung Pay will keep me using Samsung for the foreseeable future.

 

It will fail sometimes but only because the cashier hasn't enabled "credit". Then just tap again. But that only happens < 1% of the time for me. Normally works awesome and is far quicker than chip card. Works absolutely everywhere a swipe machine is installed (except plunge style readers at the gas station, hit or miss whether it works there).

A stated a few specific use cases that are part of the reason why I plan on going back to Android Pay earlier.

 

One is the ease of use when it comes to certain membership cards, specifically Walgreens. Another reason is easy withdrawal of money from my bank since they have NFC enabled ATMs that work with Android Pay. My last reason is that Samsung Pay still doesn't offer support for all of my banks/cards yet whereas Android Pay does.

 

 

Edit: Samsung Pay works with NFC ATMs. I just tried it and it worked.

This page shows that the GS8+ for Sprint does not support 2g/3g 1900/800 frequencies, just the 3 LTE bands.

 

I have to imagine this is incorrect..... right?

 

When I'm in bumf*** Egypt, I want to know that I'll at least fall back to 1xRTT.

Without those frequencies you would not be able to make a call.

 

So rest assured that they are indeed included.

 

BTW, all versions of the GS8 are in fact the same, once you boot the phone up with the corresponding sim card, it installs the carrier firmware accordingly.

Has anybody else been getting "Unable to establish a wireless data connection"  LTE: ESM-31 EMM-x" error?...randomly ?...I've called support and they did the normal profile update/ factory reset procedures.

Yes! But data is working normally. So.....unsure.

Finally got a chance to test this phones B41/B25 performance in a favorable environment attached to a site with B25/B25-2nd C/B26 and B41-3XCA

 

I tested B25 only and B41 only also did B25/B41 and kept B26 disabled for testing.

 

One thing I noticed about this phone running the latest baseband is that it switches and latches onto B26 too easily. I think their could be some tuning issues on the baseband and network side to better support HPUE.

But my testing mostly affirms Sprint's claim of 90%+ of B25 coverage.

 

Did testing at the edge of B41 signal for comparison...

 

B25 only              -112dBm 4.1mb down/2mb up 52ms

B25 only -2nd C  -113dBm 3.3mb down/1.4mb up 49ms 

 

B41 only              -123dBm 9mb down/.45mb up 120ms (Super impressed that 3XCA kept a connection at this signal level, all 3 carriers hovered around similar signal levels)

 

B41/B25 both enabled, B41 would drop around -124dBm and latch onto a B25 -113dBm signal, once I moved deeper indoors B25 would die out around -116dBm (10-12 ft deeper indoors)  So at the end of the day, they were pretty close in terms of coverage. 

 

For comparison my girl's G5 would drop B41 at -115dBm (around 15ft sooner than GS8+) and switch to a -105dBm B25 signal.

 

*Other small notes*

 

I ran each scenario at least 10 times to assure some sort of consistency, all posted results were peak performance.

 

One negative side of having B41 in such weak levels was the ping times, I almost always had 100+ ms pings when signal level were over -118dBm (compared to 20-30ms when under -115dBm)

 

Surprisingly, the uploads on B41 weren't as bad as I had expected (probably because tower was completely unloaded) Even at the weakest levels, I was seeing at least .50 upload and many times over 2mb.

 

Hope this helps folks have a slightly better understanding of how HPUE could benefit them, and also the fact that its still in its infancy and needs time to be fleshed out.

I turned off WiFi and then rebooted, I haven't had the error for about 2 hours.  I'll wait and see.

 

Edit: The error came back with WiFi off.

I just got this error for the first time today as well... certainly something on Sprint's side that I doubt needs to be concerned with.

      Its almost time for the next iteration of Samsung's Galaxy Phones! I'm planning on pre-ordering either the S20+ or Ultra. Current Rumors have it going on Pre-order February 11.  Let the discussion commence...

      Noticed on TM Reddit that the S8 Active is coming unlocked, so would be compatible with Sprint.
      (Also supports TM B71)

      I'm here looking for answers to a simple question. Where is this mystery Sprint signal coming from? For the past few weeks I've received a signal on multiple Sprint devices, two Sprint devices with roaming turned off, and two Virgin Mobile phones and Virgin Mobile phones can't roam, the other rate plans might be able but I'm talk about Virgin Mobile devices from before they introduced all those other plans. What I'm making clear is these devices have to be picking up a Sprint signal, plus I've downloaded the SignalCheck Pro app which has indicated two different signals 1XRTT and 1X800. 
       
      The signal only last for about 8 hours each morning and begins coming in and out towards the end of each morning. I try making a call and it fails, and it doesn't get any data at all. I try each device and they all do the same thing they have a signal and very strong signal with no data, and voice doesn't go threw, I haven't tried sending a text figured no data, no voice then there must be no text.
       
      I read about some "projects"  that Sprint has going on Project Ocean and Project Cedar. Since Project Ocean is suppose to be taking place in Missouri and I live so close to the Iowa, Missouri line, I figured if there is a tower going up maybe it is possible I'm getting a signal from it, in the early stages. I really don't know what is going on, if Sprint is launching service, putting up new towers and that signal finally comes, and stays, and works. I'll be back full time on the Sprint ban wagon. Unfortunately, I live in an area not served by (according to experience and coverage map) Verizon, AT&T, T-Mobile and Sprint. Not even the two Iowa carriers i Wireless or Chat Mobility serve my area, go 10, 15 or 20 miles in any direction your good, here, wireless dead zone, no choice of carriers. And if Sprint puts a tower here if I finally get an answer and learn that signal will soon come and stay and work I'll finally have a choice.
       
      So if anyone has any ideas, has experienced this in other parts of the country or has any idea what could be going on please say. Any information is better than not knowing, and together maybe this will be answered.

      Try to make this as short and simple as possible. I have three devices; 2 of which are on the same plan and the third on a separate plan.
       
      The third device is my tab 4 which is picking up SprintB41 site 310120 just great. I get 3 bars downstairs.
       
      My other two devices; Galaxy Note 4 & Galaxy Note Edge for some reason will not pick up this tower. I have tried PRL updates, Profile updates, restarted the phones and all I can get them to connect to is a ClearwireB41 site.
       
      More background info...all devices have same Sim card as when purchased, tablet stays off 3/4 of the day and my phones are on when I wake up and turn them off at night. No matter where I go inside or out my phones won't connect to the Sprint site.
       
      Anybody have any ideas before I call Sprint trying to figure something out? I'm not sure how long the tablet has been able to connect to this site so I'm not sure what to think of it besides agitated that the tablet of all things is connecting. I posted two photos; one of the tablet connected to the Sprint site; second of the Clear wire site my phones connect to.
       
      Thanks in advance.
