You can also crack the draw-a-password thing android has by looking at the fingerprint smear you leave when you do it.

That's why I've picked up the habit of wiping my phone screen a lot.
Are there any "secure" methods to unlock a phone anymore?

Long story short, no there is no secure way and this pretty much applies to all devices.
Also damn ratings being close to the reply button. :v:
What about fingerprint scanners? Are they secure anymore or can you lift the prints off the screen with tape?
Couldn't this be solved by just tilting you phone a different way each time?

When you tap your screen, it sometimes will physically move the phone. And if you're doing the password one-handed, the movement of your thumb going to press the numbers or the pattern is picked up. The gyros and accelerometer in phones are often accurate enough to pick up the very minute vibrations of our hands. So all they have to do is have a baseline position and they can decode any movement into the password. Basically you're fucked unless you want to inconvinence yourself by constantly and erratically moving the phone throughout the entire unlock process.
I suppose in theory a way to combat this would be to have the phone randomize the position of numbers/characters on the unlock screen. An inconvinence, but likely would thwart the attack.

I think in the States, finger prints don't count as passwords so police can make you unlock your phone with it.

Fingerprint unlocking is the quickest method, which already puts it ahead of all the others for me, and it also stops opportunists on their tracks. It's shoulder-surfer proof. It can be fooled, but most methods require a direct cast of the finger or a very good, oily imprint. It's relatively easy to avoid leaving those everywhere if you're security-minded.
It all depends on how you handle your security and who you want to be protected from, really.

I don't know about other devices, but after a few failed attempts, my Moto G4's fingerprint scanner will just refuse to work entirely and demand me to fall-back to the gesture or PIN. If I was in a situation where I could be legally forced to unlock my phone "because my fingerprint isn't evidence", it'd be as easy as tapping the wrong finger or even the wrong section of my finger against the sensor a few times to lock it.
Either way, a fingerprint is a user, not a password. It's only caught on because it's more convenient and 99% of phone users value that convenience over security.

Unfortunately, that would be considered contempt of court to willingly error out the finger print scanner and you'd be in jail for a very long time with no trial, as per how the US loves to work~ You'd be more likely to avoid fingerprint scanning and getting the book thrown at you by cycling the phone discreetly. First start disables the fingerprint scanner. Basically, don't use it or set it up at all.
