Cigurd If law enforcement executes a no knock warrant and breaks into your home, you have much bigger things to worry about than wiping your phone, such as being shot dead. Unfortunately, no knock warrants (at least in the USA), originally intended to be only be used in the case of heavily armed drug dealers, terrorists, and other similar suspects, are being issued by judges with increasing frequency, against people with no criminal records. I know cause it happened to me, but that's not something I care to share in more detail.
Also, standard operating procedure is for all electronic devices to be placed in Faraday Bags, which would prevent remote wiping. To overcome this type of situation, you would really need some type of app or for there to be a GOS setting whereby if you did not enter a pin within a certain period of time (say every 4 hours), yhe phone would automatically wipe itself. Risky, in the event you have a couple of drinks and oversleep, but it would nevertheless keep your data safe.
I am not recommending this type of protocol as a practice to anyone but the 0.1% of us that require such, and everything you keep on your phone is truly disposable, but if you have an extreme threat model, it might be viable.
