I asked Tmobile help on twitter and they said:We don't have any official date for the rollout of Android 12 on the Galaxy Fold 3. We do keep this link as updated as possible, which shows which devices are in what phase of getting the update. https://t-mobile.com/support/phones-tablets-devices/software-updates… This link is more specific to the Galaxy Fold 3, so this might be a good page to check back on frequently for updates: https://t-mobile.com/support/devices/software-updates/samsung-galaxy-z-fold3-5g-update-to-android-12… I hope that helps!Timo has no idea. It's very strange the other carriers released it a week ago or more in the US. It's tough because I use an unlocked version and still must wait for T-Mobile. I'm going to try buying SIM cards from other companies and registering on their Network and checking for the update and switching back to the T-Mobile SIM card. It just seems safer than flashing.
I ended up buying a Google fi SIM card. I turned off my phone took out the T-Mobile SIM card and put in the Google fi SIM card. Then turn my phone back on and it asked me to restart to apply sim updates. After it restarted I went to settings check for update and it immediately began downloading. I did not sign up for Google fi or even download the Google fi app.
I put in a Google fi SIM card and update started downloading when I went to settings check for updates. I did not downloading apps for Google fi or sign up for it. It made me reboot one time after I put the SIM card in though.
