Hey there! Quick question: are you using an unlocked phone from another carrier?
Thanks for the reply. It is an unlocked phone and not from another carrier.
Thanks for that! Have you tried resetting the APN settings to default? Press the 3 dots in the upper right hand corner and select Reset. Are you able to create a new APN and set it as the default? It's certainly worth a try. Don't forget to reboot after making any changes to the APN.

- APN protocol: IPv6
- APN roaming protocol: IPv4
Failing that, the only way I've been able to find to permanently disable IPv4 is to root the phone, which at the least may void the warranty, at worst may brick the phone. Good luck!
Thanks for your reply back. I did reset the ACN to default as suggested. I also created a new ACN and restarted the device. I'm still seeing a fallback to IPV4 as shown in the attachment. Do you have any other suggestions? Thanks for your time!
I see! I get the same when I run the test on that website.
My understanding is that it only flips to IPv4 when a website takes longer than a 1/3 of a second to load. Perhaps there simply isn't a way to avoid having a fallback assigned (without a root, or maybe even then)? This is only speculation on my part.
I'm really sorry that I'm not more help! Are you noticing a specific change that would signify that your connection has flipped to IPv4?
Not sure what you mean. That is only applicable if v6 doesn't work. Why do you want it to not fall back?
The reason why I want IPV6 only, is because I connecting to an application that only supports IPV6 and when there is IPV4, it doesn't work properly.
Ahhhh, I see! I was a little curious about that myself. Digging around, looks like the only way to do that is to root the phone and that's like Greek to me! I do wish you luck figuring this out!
The fall back will only occur when the ipv6 can not connect from my understanding. And if that is the case you won't be able to connect at all.
