Thorfinn So i just dont know how safe the "nearby devices" is and what exactly it does, if someone could clue me in on how it works then maybe i would be comfortable using play services with just the nearby share on my main profile as well.
Here is some information: https://www.thelasttech.com/android/what-is-nearby-devices-in-android
There is a privacy issue, which is that some businesses may use Bluetooth beacons, and meanwhile home devices with Bluetooth may have their MAC addresses and locations harvested over time (the same is true of Wi-Fi AP MAC addresses). So if a program (such as Play Services) watches for wireless MAC addresses it can track location.
But Quick Share inherently needs to scan for nearby phones in order to share with nearby phones.
It's up to you.
