Wi-Fi and Bluetooth scanning for improving location detection are disabled by - default, unlike the stock OS. These can be toggled in Settings ➔ Location ➔ Location - Services ➔ Wi-Fi and Bluetooth scanning. These features enable scanning even when Wi-Fi or - Bluetooth is disabled, so these need to be kept disabled to fully disable the radios when - Wi-Fi and Bluetooth are disabled. GrapheneOS doesn't yet have an implementation of a coarse - location service to supplement GPS location, so enabling these options doesn't - actually do anything at the moment. Implementing a supplementary location service is - planned but we need a robust, secure and private implementation via a local database. - The initial focus will likely be a cell phone tower database, so these features still - wouldn't be relevant.
