can someone confirm that VoLTE works?
I thought it was working, but I do not believe it actually is The singal icon changes from 4G LTE to just 4G when I start a phone call. I still think this rom is better than any MM rom I have used, at least until T-Mobile releases their own nougat update.

I seem to not be able to have a lock on my screen. Is there something I'm missing? I set up a pin and fingerprint, but the lockscreen still just says swipe to unlock.

Check the baseband in "About Phone" to make sure the modem updated. It may also be that the bootloader did not update.

Security on past Samsung devices has been dependent on the modem and bootloader. Suggest you check to see the bootloader also reflects G930A.
ADB check, as well as *#1234# show that all of the G930A files are installed correctly.

Edit: Disabled my pin for swipe only, restarted the phone, tried to reenable the pin, settings app crashed, then it allowed me to do it eventually, only for the pin to not be required on the lock screen. Odd. Cant use Goodlock either. Dont want to use a different lockscreen because I like the rotating backgrounds.

Edit2: Am now having a lot of connectivity issues. Says I have LTE, but cant connect to things. Wifi is failing to work reliably as well.

Are we supposed to change the API settings for this one, like the VZW one?

Edit: Nope. Did not work. Would not recommend using this firmware at all.

Flashed successfully. So far, so good. Change the APN to t-Mobile from my note 5 and LTE icon came on but then came right back off. Right I'm on wifi but will report back tomorrow for more results with out of the house use. Call, internet, text, gear are working. I even got the network T-Mobile on my status bar . I also checked on network options in settings and was surprised how many option I had (even project fi). Any way just thought I'd report.

Update: does not lock. Same setup everything pattern and finger print.

Pretty smooth, got a little warm but could be because of all the updates and setting up.

The settings to lock are set to 10mins, change it. Is your LTE working??

I haven't had a chance to get out of the house and see if it works. I tried within my house and the LTE icon never shows up. I have seen it once for a second but haven't again. I get bad reception within the home so I'll let you know when I'm out and about.

Thanks for the info on changing the Lock to instantly instead of 10 mins after.

Update 02/10: lost data finally got out of the house and all I get is text and calls. I played with apn settings and had 4g LTE icon show up but no data. I probably shouldn't of played with apn setting. Going to reflash and see if it fixes anything.

Could we flash the t-mobile modem(CP) with this get it to work?
Tried flashing the latest AP1 CP and had no luck. Decided to start over but had to get back on t mobile,,, the first firmware. Flashed that, then att latest and then the nougat update. I also thought I'd skip wifi connectivity and went straight to data.
So far it seems to be working good (an hour out in the streets now and letting it do it's updates(this might take a while but I have data)). Im going to remember retrack to what I did that may have caused me to lose data and going to try disabling some att apps, connecting my gear s3, etc. (which may be the cause). Will let you know on my results.

Update: disabled att locker, att protect plus, att caller id, direct tv, hangouts, my att, setup and transfer, smart limits, uber, and lookout. So far so good. As soon as I get home going to try wifi calling.

I would recommend reflashing and not connecting to wifi and let the firmware settle in for those that don't have data.

I did the same thing, re flashed and all. I noticed the mobile internet worked before I flashed the update. After the update it forces me to set-up again. :confused:

I figured it out. All you have to do is take out your sim card and put it back in. Works Perfectly!
