One of the big improvements ushered in by the Samsung Galaxy S10 is its in-display fingerprint sensor. This is a first for a Samsung phone and it negates the need for a front bezel or clumsy reach-around. However, it turns out there’s a trick to using the ultrasonic sensor that will make your Galaxy S10 unlock much faster.

According to the Android super sleuths at Ice Universe, the S10’s fingerprint sensor works much better when you caress it gently rather than going for a hard press. Applying sustained, featherlight pressure is key.

Here’s the slightly hysterical advice from Ice:

“The correct way to unlock the Galaxy S10 ultrasound! Please don’t press the screen, you just need to touch the screen gently, it will be unlocked soon, don’t press the screen! This will be slower.

Easy on the exclamation marks, boys. You can see the different result each method produces in the accompanying video:

It’s also good to know that the phone can be unlocked without turning it on first; an ability that previous in-display fingerprint sensors have lacked. This might seem like a minute change, but it really adds up over the course of a day.

Over the course of the next few weeks there are bound to be more quirks and eccentricities uncovered by users – some of which will doubtlessly be addressed in a future S10 firmware update. But for now, it’s best to adopt a softly-softly approach when unlocking your new phone.
