First, not trying to fud, just I'm wondering :

If Peter Todd in his part of "Zcash Trusted Setup Ceremony" https://petertodd.org/2016/cypherpunk-desert-bus-zcash-trusted-setup-ceremony used BLU android smartphone to have internet connection, could it be somehow compromised ?

Recently some chinese smartphones including BLU R1 HD, were identified to have some spyware installed. Not an expert here, but Peter's model looks like Studio X8 HD (2Q 2016).
