Installed QPR2.1 update released on 20th of Jan 2023 which mentions fixes to 5G connectivity issues. But it made zero difference to 5G reception of Jio. It doesn’t latch to 5G network at all unless forced using Android service menu. But then it latches to only Band n28 (700 Mhz) and speedtests fail to complete with hardly any data connectivity.
Can’t believe a big organisation like Google who MAKES Android cannot get 5G cellular connectivity right. Bunch of incompetent fools in their wireless radio dept.
