The German shrooms vendor Pilzhof on Nucleus uses Android. You can see that on this PGP key, which was created by APG v1.1.1 - an Android app.
I have asked him about this, and he claims that he uses dedicated hardware and an anon sim card. Obviously, that doesnt convince me. I would not buy from this vendor - even though he (apparently) has a good product and sweet prices.
Thoughts?
Android is basically a flavor of linux, and open-source. It isn't inherently unsafe like Apple hardware.
Most vendors have a few android phones. However, its unusual to use it to access onion sites. I don't think there is an up-to-date version of orbot.
I certainly hope he's using an android that he never makes calls from. Android phones are for bitcoin wallets, and encrypted messengers The US and UK governments have managed to suppress modern consumer encryption on PCs, which is why some people are still using 25-years old Pretty Good Protection.
Obviously, Apple is in the US government's pocket in return for paying less tax than I do, but android phones with P2P encryption slipped through the net, and are well-rated by privacy groups.
If your vendor is using TOR and PGP on a tiny hideable linux device with its own untraceable 3G internet connection, it shouldn't compromise YOUR safety. If you're a Panicky Prudence, he probably won't miss your business anyhow. Let a better customer get that last bag of good drugs, ordered while the vendor is in the post office.
