[Q] Wi-Fi Calling - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Last week Sprint extended Wi-Fi calling to the Tri-band (Spark) S4.
I had the software pushed to me this morning, and installed it.
Now I have the Wi-Fi icon in my status bar.
It disappeared when I went out, and re-appeared when I came home and connected to the wi-fi.
I'm guessing that's all I have to know about it?
Does anyone with wi-fi calling experience have any advice or caveats?

I got the update notification this morning, and clicked install, and then the phone rebooted, but into twrp; I then just rebooted back into my sytem, but I don't see anything about wifi calling so I have no idea if I have it or not. I thought it had to be activated on sprint website.

I don't think it installed since you are on a custom recovery. You have to be on stock recovery if not the update will fail.

Thanks Daniel
I just realized the problem and did install the stock recover image file. Guess I have to wait until Sprint decide I'm a good girl and re-send the update. Checking for update doesn't seem to do a thing.

Actually, you can just go to your Settings --> More --> System Update --> Update Samsung Software, and after click on it, you can then redownloaded it again.
I was wondering though, does anyone know what this update file is called, because when I tried to install this, it says, "Rebooting now... - 36.0 MB" but then just sits there, and doesn't do anything. I want to know the name, so I can deleted it and then try downloading it again. A little side note is that I have rooted my Samsung Galaxy S4, and updated it to KitKat. It is now running 4.4.2.

ICS Has landed in the UK!

Hi All
Just did a check for update via my tab, and it is, as I type, downloading the ICS Update!
Anyone else, if you havent done so, check via System Update in Settings.
As per the title, I live in the UK (Midlands).
Running stock rooted 3.2.1 Gen 1 f/ware
At last, the much talked about topic has arrived.
Do you have 3.2.1 com_gen1 or ww_gen1 ?
Yeah your right, downloading now, just outside london very near heathrow airport
Sorry for my English...
What 3.2.1 do you have com_gen1 or ww_gen1 ? Look in setup/tablet info...
I'm in the netherlands and just got the update.

I not sure then, could try powering off tab then power back on, turn wifi off before power down then once booted up turn wifi back on, but this is just a wild guess.
yeah this is bull crap lol still nothing after trying the above

[P907A] New Software Update P907AUCU1ANK2

It looks like Samsung and AT&T have released the SM-P907A's first software update. It's still Android 4.4.2 but fixes a really major bug that caused the System UI process to go into an infinite crash loop when you would adjust the volume while connected to a Chromecast.
As far as the BSOD goes, so far, I have not experienced it with this new firmware. That said, I want to use it for at least a week before I say for sure that it's fixed.
One bug that doesn't seem to be fixed, though, is with VPN. Using the standard Android VPN functionality, I can connect to my work's Cisco VPN via IPSec Xauth PSK on any Android device except on the P907A. If I set it up, it connects, then immediately disconnects. Annoying.
AT&T also added a bigger, more gaudy 4G LTE icon.

Mine is still BSODing after the update. No difference, and maybe worse...
Yep my SM-P907a also getting the blue screen the update hasn't fixed the issue.

Every OTA is going to unroot your device. That's just a fact of life with Android.

It unrooted mine also, I even had the box checked in SuperSU to try to maintain root. Guess I may have to look into reverting back to old firmware...
EDIT: I ended up using ODIN to go back to stock. After doing so, I rooted using towelroot then before installing SuperSU I used the debloat script to disable Knox and the updater. This has allowed me to have root without Knox tripping plus no random reboots. In short use the debloat script and not SuperSU to disable Knox and you will be good to go.

I am working up a post here in general outlining how to do everything I talked about.
I just got mine back from Samsung repair for the 3rd time. So in total, they have replaced the motherboard twice, the screen twice and updated the sw each time. It is still doing the blue screen nonsense! I'm really discouraged. I can't find much online about this problem. I will keep up with this forum in hopes of someone being able to come up with a solid solution. I have lost my faith in Samsung. Lol and that's sad because every device I own is Samsung. Over the past few months, I have managed to teach myself how to root my tablet...any further than that gets really confusing. Lol so any help would be appreciated!

Can you check which bootloader version it is please. Go into download mode/Odin mode and look for the thing that says either B2 or B3. If it says B2 it's still bootloader 2, if it says B3 it's bootloader 3. Report back ASAP. I would really like to know.

It tried to update. Funny story is I accidently booted into recovery mode in lieu of bootloader mode by mistake so quickly changed buttons mid vibration and booted into dl mode instead of completing the update. No idea what completed or didn't.

Hmmm not being able to odin back to stock is kinda scary TBH. It kinda sounds like the bootloader tried to upgrade or something since if the bootloader was still B2 it would flash fine.

That was my thinking. I had a few errors in ODIN, both versions. Also tried several versions of the firmwares from different locations. I got lucky. Hence my hastily FYI on here. Lol

so I'm guessing if I take this update I won't be able to root later if an exploit is found, right?

Not for me...try to
1. reboot, if not fix
2. boot in recovery and clear cache, if not fix
3. Cache and data, if all else fails, sometimes updates are screwy and we need to
4. Factory reset...I hope you don't have to do that. I only reset after major updates...use Helium to backup your apps first (that's what I use)...sorry S Pen is having issues for you
Before any of that find the spen app or settings app and clear that cache and data or reset just the settings of your phone under the general management section

I have a G930F, so it's the flat screen model but i'm having exactly the same issue.
Flashed BTU CSC, not CSC home. let it boot, went into recovery, wiped. WiFi still has issues even after a clean flash. The ! symbol sometimes appears and I lose access to the internet until i turn it off and on again.

The same thing is happening to my S7e and I updated it the same way as you. It's a pain in the arse and I'm considering rolling back to Nougat.

SAME PROBLEM HERE MATE !!! i also created a topic > https://forum.xda-developers.com/s7-edge/help/help-connection-problem-lag-upgrading-t3789737
a lot of times the ! symbol appears, and i have the lag/drop/freeze of connection. Even while using WIFI or 4G mobile !
Yesterday was a really pain to call Uber, since the 4G symbol was there, but the internet was really really slow/sometime now working.
i wasnt having those bugs on android 7 =/.
The funny fact is im from Brazil (ZTO), and i received this Android 8 update... Using S7 edge SM G 935F

The same thing is happening to my S7e and I updated it the same way as you. It's a pain in the arse and I'm considering rolling back to Nougat.

SAME PROBLEM HERE MATE !!! i also created a topic > https://forum.xda-developers.com/s7-edge/help/help-connection-problem-lag-upgrading-t3789737
a lot of times the ! symbol appears, and i have the lag/drop/freeze of connection. Even while using WIFI or 4G mobile !
Yesterday was a really pain to call Uber, since the 4G symbol was there, but the internet was really really slow/sometime now working.
i wasnt having those bugs on android 7 =/.
The funny fact is im from Brazil (ZTO), and i received this Android 8 update... Using S7 edge SM G 935F

I don't know as I haven't looked into it yet. All I know is Oreo repartitions the internal memory so I don't know whether rolling back will undo this (probably not)

Hi, I've updated my firmware to android oreo, ever since the wifi is really poor keeps dropping and lagging. Also network connection is poor drops every now and then. I updated via Odin. Any suggestions would be appreciated

Hi,
My S7e has just upgraded to 8.0.0 and is now having the same wifi lag issue. Did you manage to find a fix?
Thanks
Ady
I tried a different kernel and now both my.wifi and Bluetooth are working like a charm. Before on Oreo my wifi switch went completely gray and in order to get the Bluetooth to work , Everytime I had to do a network reset. But now it's working great.
I had another issue, my security was pattern unlock and it would take a minute for it to unlock and sometimes in between the screen would turn off, that problem also got solved with the kernel .

You do not have the same issue as us and as far as I'm aware a kernel swap would mean our devices had to be routed.
