Background

PS my pixel 3a is running android V 10.

I’m back in Canada now and it’s successfully running VoLTE and preferred network type LTE.

Per BobTheE I ran my phone IMEI on the T-Mobile Bring Your Own Phone (for the US) eligibility page and it was successful, details in my post above link.

Question

I’m a late adopter to upgrade operating system(s).

And I’m thinking the android V 12 upgrade might give me some improvements to 4G to increase my confidence when I’m in the US in December.

Are you thinking I should just upgrade to V12 now, or wait until October-November 2022 when’s it’s more patched?

Thanks,

Bob
