[Galaxy Note 4 Android Development (Snapdragon)] AnonVendetta:
I have what i believe to be very bad news for users of the stock firmwares i've provided, this deodexed firmware, any possible ROM/kernel i have planned for the future, and for Note 4 owners in general. The gist of it is that i'll possibly be forced to end active development for this device early and move on.

Yesterday i received a text from my carrier (MetroPCS) stating that i would need to have VoLTE enabled on my device by July, or risk loss of service. As for the exact day, i cant remember. MetroPCS is basically a subcarrier/MVNO of T-mobile in the US, so it would probably apply to N4 owners on their network too. I also think this will apply to most other carriers too, especially if they're GSM/SIM based. There is also a big push among major carriers to move away from 3g/4g in favor of 5g. i'm assuming i'm not the only one who got this text, other users on the Note 4 XDA subforum are discussing this too.

As i see it, the possibilities are:

1. My 4g LTE internet/texting will continue to work, but calling will stop working. Not an acceptable scenario to me.

2. Internet, calls, and texting will completely stop working. Obviously not acceptable either

3. Everything will continue to work as usual. i view this possibility as unlikely

This issue will most likely affect users of ROMs that are based on AOSP/LOS/CM, since none of those support VoLTE on the Note 4 (that I'm aware of).

i have to assume the worst and take this text seriously, although i'm still adopting a wait-and-see approach. But i also have to be prepared to buy another phone if/when the worst happens. i had hoped to keep this phone working until the end of the year, but it seems that plan may be cut short. i fully intend to keep at least 1 Note 4 around as a wifi only device, and i will continue to use it until it stops working. So this doesnt necessarily mean development will stop even if the worst happens. it just means that it will probably take a backseat.

At this point in time, i cant make any guarantees one way or another.

However, I'm going to have to ask for help from as many users as possible. I'm hoping that the text just means that i need working VoLTE and things will be OK. 4g itself shouldnt be fully discontinued globally, i'm guessing that most carriers will continue to support it in some capacity until between 2025-2030. 3g will probably die a quicker death.

So far I havent found any firmwares for the N910F that have working VoLTE, although I've only tested a few. I've read that the N4 and F in particular are compatible with it. So it's a firmware/carrier thing, not hardware.

Reports from N910F owners are preferred, but i will accept reports from all Note 4 users regardless of model. The goal is to get as much info as possible by July 1st.

On my Androidfilehost profile (just Google "anonvendetta androidfilehost" to find it) there are 68 N910F firmwares. These are 100% official and unmodified, Odin is needed to flash them. Obviously if you dont have an F then trying to flash these wont work. But i'll accept info from any Note 4 owners.

Download 1 or more of these, flash them, and have working/active mobile data service in your phone. In Android, select your carrier APN, if your mobile data isnt working. If it is, you can skip this part. Open the phone dialer app, go to call settings, see if there is an option to enable VoLTE. Also check for VoLTE options in "more networks" within the Settings app. if it exists in either or both, enable it, reboot, let me know if you have working VoLTE (it should say so in the Android statusbar).

Screenshots are preferred too, if you can get them.

Other info I'll need, if you have/know it:

1. Your country

2. Your carrier

3. What Note 4 model you own

4. What Android firmware/ROM you're running (either from the firmwares i uploaded, or whatever else)

Out of the 68 firmwares i've provided, i just need to know which, if any, have working VoLTE. That's the most important thing to me right now.

Assuming the worst does happen, i may buy a N910T Note 4 (T-Mobile model), i've read that it natively supports VoLTE with my carrier. Or i may just bite the bullet and buy a new, modern phone that supports 5G.

I'm looking forward to see feedback, but i need it soon. And the more, the better. Thanks!
