My 5a sensor is fantastic (it is on the back). I'll be sad when it's time for this phone to go.

Behind-the-screen fingerprint scanners are an abomination.

Always reminds me of 1984's telescreens. We're almost there.

Mine works without issues since I removed the white circle and the unlocking animations.

Not my experience. They are usually instant, but you need a flagship device, of course. Otherwise it's comparing apples and oranges.

First gen in-screen scanners were absolute trash. Borderline unusable. But the tech has improved quite a lot since the first ones. The one in my galaxy tab s9's screen is fast and accurate.
