I am using Android 12 beta 2 on my Pixel 3xl with Republic Wireless.
The Android 12 beta 1 worked great, no issues. I upgraded to beta 2 and things got messy. First, the Republic app started telling me I needed to activate when I tried to dial a number. When I clicked the “activate” button, it would tell me the phone is activated and suggest I restart. This did not fix that issue.
Then I would start seeing the green screen telling me “Awesome, this phone is supported…” It tells me I can buy a SIM card. below that, a link telling me to install a system update so I can use Republic.
None of that works… so, essentially, there are some issues with the Republic app that need to be worked out. I got the same answer when I shared with Republic support… They don’t support beta releases and suggest I revert to a general release.
Here’s what I found to get it working with Android 12 beta 2:
open the Google dialer app
dial * # * # V O I P # * # *
you should see the green screen showing your phone number and it telling you to restart. You can swipe it away (do not restart for now).
If you restart, the Republic app will crash and you will have to do the dial again.
As for SMS, I had to load Republic Anywhere on the Pixel. It works.
I have filed a bug with Google in the beta program for the Republic app. Fingers crossed they will work or encourage Republic devs to upgrade their libraries, etc. and release a new Republic app.
Enjoy Android 12 beta 2. Lots of new things to explore!
