How much of a target are you?
The phone doesn't actually store your fingerprint, just some vectors used for comparison. You can't recreate a fingerprint from that data, but you could recreate something that'll pass as a fingerprint on that particular device.
If I was a major player and I wanted your fingerprints and DNA, I'd let Royal Mail do all the hard work for me. I'd send you a bogus letter from the DVLA or HMRC asking you to confirm some details or claim a refund or whatever. You fill out the form (leaving your fingerprints all over it) and lick the gummed strip on the prepaid envelope (giving me a nice smear of DNA). The government could of course lift this from a legitimate piece of correspondence.
I could also send someone purporting to be delivering a parcel or doing a questionnaire, then lift your prints off the clipboard. You can usually get a full set from a clipboard - people tend to accept it in their dominant hand when it's given to them, but then switch to their non-dominant hand when they're given a pen. The stooge can also hand you the clipboard twice by asking you to hold it for a second while they tie their shoelaces or faff about with their deliveries; by handing it to you from the paper end and the clip end, they maximise the odds of getting a clear set of latent prints.
If you're really paranoid, I'd lift them off your recycling bins or your car door. I could also bribe a cleaner at your workplace to steal something likely to carry your prints.
With a top-tier DSLR and a long tele lens, it's possible to take a detailed picture of your fingerprints from across the street. 99% of keys can be duplicated in this manner as well.
Don't fuck with nation-state adversaries.
