I read somewhere that markets where Google does not officially sell the phone don't have the feature enabled, and from what I read on the link above, the whitelisting is an override of the list... am I even making sense? lol
Rootless replacement for persist.dbg.volte_avail_ovr patch - kyujin-cho/pixel-volte-patch
github.com
From my research, this patch won't work on 5G cause that's more technical or maybe that has a whitelisting... well, it's not relevant in the case of Pakistan, so...
Speaking of the Pixel 7, how quickly does it heat up in your experience? I presume you're in one of the major cities where temperatures cross 40 C easily during the summers, so how does the phone behave in those temperatures (given Tensor)?
