When you go to settings > mobile networks > mobile data under mobile data does it mention "AT&T Video Call and push notifications over the cellular network"?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
So, my phone has been alright since I switched back to the 935A firmware using the June patch fw posted in the forums. Now just last night and today, I can't recieve calls. It sends people straight to my voicemail. Anyone know why this is happening? Or how I can fix it? I could have sworn I saw someone mention the same problem somewhere in the forums but I can't remember where and the search isn't finding it. What should I do?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Tikerz:
Ok, then I must have done something positive lol. I assume you've enabled the VoLTE and video calling in the others.xml. I went further into others.xml and changed all the product or sales codes from XAA to ATT in the file. When I saved and rebooted I went to the phone app and the AT&T video call popup came up with instructions on how to use it. Then I also noticed that in mobile data it mentions the AT&T video calling. There was also a setting that mentions CDMA and changed that one to FALSE since we're not on Verizon or Sprint.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Skizzy034:
Have you tested it?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Tikerz:

Turn off Enhanced LTE Services under Settings>Mobile Networks>Mobile Data. It's an issue that OP refuses to comment on
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Thanks, Ill see if that works. But still, I wonder what would be causing this? I reverted back to the stock firmware using all 4 files in odin. Do you think there could have been something wrong with the files that Rapazzo posted? Because that's what I used. Its supposed to be the stock AT&T firmware with the June patch update.

Maybe I should try flashing the older stock firmware from AT&T and then do the OTA to the June patch?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] wahoofan5:
No, I firmly believe that this 935U firmware permanently breaks something within the S7e hardware. Myself and a few other posters have actually had to get warranty replacements from AT&T. Absolutely nothing I've tried has gotten it to work again
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Venom0642:
Looks like you can downgrade to PB5 : http://xdaforums.com/showpost.php?p=67649300&postcount=109
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Tikerz:
If you're on non-rooted 935U you shouldn't have that option. I am rooted and enabled that option through the others.xml file and I can receive calls just fine.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] dredq:
It is hard to believe that this would be a hardware failure. It seems like it is software...most likely with the radio....but I don't get why it is not working after being re-flashed. I am sorry you and several others have had this issue. It seems to be an ATT only problem. No other carrier phones have had this issue...correct....which again seems like it is software vs. hardware. I am glad you were able to get a warranty replacement. I believe this should be posted in the 1st post in RED for anyone about to try this firmware. Again, sorry this happened to you.

well i have flashed like crazy trying to get phone to rec. calls but then cant send texts and vice versa. with enhanced lte on i can send and recieve text and place calls but cant receive they go stright to vm, and with enhanced lte off i can make and receive calls and recieve texts but cant send text weird. any help or info would be appreciated
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Well, I'm still learning alot of this stuff.. Ive been doing some looking around through my phones files. My wife also has the S7, totally unmodified. I just went through the customer.xml and others.xml line for line on both our phones and everything is identical. So I can at very least say that the problems with my HD calling and Enhanced LTE does not lie within those files.

I really don't want to have to ask AT&T to send me a new phone. There must be a way for me to restore the features that my phone came with...

If someone figures out a way to enable carrier-specific functions on an unlocked phone, then I should definitely be able to restore the carrier functions that my phone came with using a similar method.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] dredq:
Yeah...I don't know. It really is weird. I am sorry this is happening to you. I would return phone to ATT or try to get it reflashed at Best Buy.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] burna:
can you send and recieve texts also? and what line did you change to get it working
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Ok, upon looking through both our phones, I found one thing that's different. My phone says that IMS registration status is not registered. It says registered on my wife's phone.

Yep, her phone is completely stock, with the June OTA. I just followed a guide online on how to register IMS and after resetting its now saying my IMS is registered! However, i still can't recieve calls while enhanced lte is enabled, and i can't do video calling at all.

I have the same problem and I flashed the roms in so many different ways and nothing helped. I put my friends' ATT sim card into my phone and I could answer calls while enhanced lte is enabled.

Maybe it is a ATT side problem and they blacklist my SIM/phone/IMEI or has some tricky logic.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Actually texts are working just fine with enhanced lte on/off. Just tested. So far it seems that hd voice, receiving calls and video calls are the only thing not working.

which fw are u on? rooted?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] ShrekOpher:
If you are having issues when you go back to stock firmware try using smart switch instead of flashing via Odin. It should fully fix any issues. Use the emergency firmware recovery and do the initialization process. This will apps the phones internal storage though.

Also as an FYI for the T-Mobile users (G935T) this process will soft brick your device if you are on the newest release. G935TUVU3APG1 Firmware
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] dredq:
That is really very interesting. Maybe the solution is to get a new SIM card

So I flashed this 935U software only my 935A, was all psyched but now I'm reading something is broke on the phone now? What got broken? and is it only broken if I go back to the AT&T rom?
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Skizzy034:
Can you upload your others.xml or post the lines you changed? I changed all the sales codes to ATT but I don't get the same things happening as you did.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
Just got off the phone with AT&T. Theyre claiming that support for the S7 should be coming soon for Kies/Smart switch. They couldn't help me with this problem at all. ( not surprised) but I did learn a few things. The IMS registration is tied to the enhanced LTE features. So while ELTE is enabled, it will say your IMS is registered and if you disable it, it will say IMS not registered. So that's why it was different on my wife's phone vs mine. I have Elte disabled atm because i cannot recieve calls otherwise.

Of course I didn't tell them the problem started after flashing back to their firmware, I simply told them the problem started after flashing the June security update. They even checked all the info on my phone. Baseband, kernel etc etc, they said everything matched up to what it should be. So the firmware that Rapazzo posted in the forums is indeed the updated June firmware.

There was a guide on XDA that I found through google. It was for the S6 and 7. Just a simple process of shutting down phone, removing the sim, putting in back in, and starting up again, with a few other steps. I thought it worked but the results were just frok toggling Enhanced LTE on and off like I mentioned in a post i made a few mins ago.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Skizzy034:

I think I found the fix for the VoLTE woes. Dial *#*#4636#*#* and turn off ims registration required

That might be just disabling volte like what the menu setting does when you turn it off.

My wife has the same phone her VoLTE is on and her ims registration is off. I even went back in the data menu and enabled Enhanced LTE on my phone and calls are are now coming through with the enhanced on where before they were not.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Jnewell05:
VoLTE is broken for many after restore. You can call out, however calls made to you are automatically sent to voicemail. Disabling Enhanced LTE allows phone calls/LTE however you don't have VoLTE.

Some report no errors other like me have this issue.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] lovelybai:
doesn't work for me. Did you reboot your phone and you could answer the phone with volte on?

Nope, I'm back on the A firmware. That's when all these problems with enhanced lte started. After factory resetting and flashing the 935A June patch.

Idk if it'll provide any a insight, but here's what I had done to my phone. I tried the eng root on my stock ATT Edge when that came out. Had problems even aftet tweaks, so I unrooted. Then the U firmware came out and I decided to try that. Flashed the U firmware and I liked it, but I was really missing the ATT specific features, especially the HD calling. I have some hearing issues and the HD calling was amazing. I've never been able to hear so well on a cell.... Also engboot root wasnt working well with the U firmware either, soI decided to revert back to the A firmware for now until a one click root or something similar came out for the U firmware, or they figured out how to enable the carrier-specific features.

Then I downloaded the stock firmware (PB5 i think? Id have to turn on my pc and look) The Feb firmware. I tried to flash that but it kept failing in Odin (no matter which version). Then someone in the 935A thread said to flash everything but the BT in order to get back onto the A firmware. That worked... However, not flashing the BT had a negative side effect... The phone wouldn't let me OTA or manually update to June... Kept saying I was up to date on Feb firmware! So that turned out being no good.

Then I found Rapazzo's thread with all 4 of the files for the June patch. I factory reset, and flashed all 4 in Odin. Success! I was back to where I started... Or so I thought... According to everything Ive looked into, my phone is back to stock 935A with June Security patch, but my Enhanced LTE features won't work, and I can't recieve phonecalls :(

And that's where Im at currently....

Were you able to to do video calling? Did you notice if HD calling quality was working?

We all whimsically jumped on this grenade. I said i was done with this life, i said i would just let my very stable and great phone exist.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] burna:
Well it seems i have resolved the issue for the enhanced lte at least for my phone. What i did was flash the full Ufw, setup with login in to gmail and samsung, rooted phone with the engboot and then pushed su. After a while let my phone update but for some odd reason android process kept closing then it said i had no sim. Dont know why, so i flashed the full pf2 fw(bl,ap,cp,csc) not the ap only one, let it boot up and everything back to normal in and out calls work and sending and recieving texts work. Dont know what happened but will not be messing with it for a while. Know im on g935a and will test other stuff tomorrow.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
ATT is sending me a new Sim to try. I doubt it'll fix the issue but I'll let you know. Next step is phone replacement. Honestly I don't mind having them replace the phone if it comes to that.

[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Jnewell05:
No one knows why VoLTE was lost.

If you were to talk with someone using VoLTE it is so crisp/crystal clear. It's the difference from 480 to 1080 on your home TV. Both phones would have to have VoLTE for it to work. Chances are that you never talked to someone with it. Even though it's enabled it doesn't work unless the other phone supports it.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] SinisterDev:
I just wanted to root my phone really. I like several of the root features and utilities. Helps keep the phone running better/longer in my experience. Also, I do some mod testing for apps in another forum I belong to. Being rooted enables me to disable signature verification in lucky patcher, which really streamlines the the process, because then I can install one version of an APK right over another. Without root, im forced to completely uninstall the apk, then install the new modded version being tested and wait for all the files to re-download etc... Just ends up taking alot more time and being really tedious..

I really enjoy modifying and tweaking things.. Idk, Im a nerd lol. PC's are more my area of expertise, but learning all this stuff about mobile devices is quite interesting.
[AT&T Samsung Galaxy S7 Edge Guides, News, & Discus] Raven2k360:
So is VoLTE and Enhanced LTE the same thing? I did the mods, but only found entries for VoLTE, not Enhanced. And is there any way to verify whether Wifi Calling actually works?

Maybe someone can PM him and see what he says. I'm still rooted on the U FW. I haven't gone back to stock yet. Will one of his roms work with all of the variants? I thought I saw he had a U specific rom and the U firmware is the same for all devices.

The only other things I can think of are try resetting network settings only and/or once back on the stock FW, run the rooted engboot and then flash back to stock.

Holy crap. First of all, I'm on 935U firmware and the ENG kernel which has pretty poor performance, lots of lags and stutters even with kernel tweaks.

I had this idea of flashing the CP (modem/radio) file from the 935A firmware to try and fix this VoLTE stuff we've been working on with this 935U firmware. Not sure if it fixes the VoLTE issues yet. Haven't tried video calling yet.

But, an interesting side effect is that performance is WAYYYY better! Stock feel and super responsive! AnTuTu 125K where as before it was only 95K and laggy and stuttering.

So basically, I'm running:

935U firmware (AP, BL, CSC)

935A modem (CP)

ENG Kernel
