Does it provide tools to lock down GPS and WiFi-based geolocation? And turn off scanning WiFi APs? Just allow manual selection. Also, can you flash firmware?

  I got some helpful answers from Termux GitHub issues: mirimir> I'd like to totally lock down the GPS chip. xeffyr> Not without root and some actions will be device-specific. mirimir> I'd also like to turn off WiFi-based geolocation. xeffyr> Android settings isn't enough ? Or you think the settings are no-op ? In such case delete the Google Play services immediately. mirimir> And totally prevent sharing of location data, anywhere outside the device. xeffyr> Disassemble your device and cut the all antennas and optionally USB port. mirimir> I'd like to turn off scanning of WiFi APs. xeffyr> Again - go to Android settings and turn off. mirimir> And just connect manually to a private AP xeffyr> Impossible if previous 2 points are performed. mirimir> for connectivity via nested VPN chains. xeffyr> You really think that VPN chain is more secure than just 1 VPN ? From encryption side it is but you forgot about side-channel attacks. Time (worldwide) and connection metadata are your enemy here. mirimir> If possible, I'd like to disable or wipe the GPS and baseband firmware. xeffyr> Find the right block device in /dev/block then fill it with zeros. Example: dd if=/dev/zero of=/dev/block/mmcblk0p8. xeffyr> Some devices do not expose the baseband block device or have it in permanent RO mode. xeffyr> GPS can be completely disabled by recompiling kernel without its drivers + modifying init.rc scripts in ramdisk to disable gpsd service. mirimir> And then use an external WiFi router or cellular modem/router. xeffyr> Good luck with modifying Android OS framework. It does not natively support external wifi or cellular modem.
