I’ve seen those settings in the various scripts in the vendor partition, os / public / devices / brax / vendor_brax_brax3 · GitLab, this partition contains all the Mediatek binaries and several scripts that load services and kernel modules during Linux initialisation.

They have an app in play store but every app there is not for this phone!

Use Aurora or download the apks manually.

I am using aurora…Google is blocking me!

That’s ok-I don’t particularly like them either and dont trust apps from their store!

Kill Aurora and run again, if it persists there is a setting where you spoof the phone model, use Pixel for example, else download directly the apks from apkmirror etc
