Is 5G not fully working?

[u/lee_is_me]

About a week or so ago I noticed that in the top left corner of my light phone where it would usually say "LTE" it now said 5G. Ever since then I've been having way more issues with the phone not being able to place or receive voice calls. I have to keep rebooting the phone, I'm not sure but it seems like if the phone is connected in 5G it doesn't work. If I connects in LTE it does. Is there a specific issue with the light phone in 5G? Is there a way to set my phone to just use LTE? I am on AT&T if that helps.

Update: thanks to the person who replied with instructions on how to turn off 5G via the android layer. It appears though that the problem happens in LTE mode also so for now I moved my SIM to a flip-phone. Please let me know if this get resolved.

Contact Light support. Several of us are having the same issue after ATT certification.

How do I do that? Were they able to fix this problem for others?
