Seriously. I'm tired of blinding myself at night when trying to sleepily check my phone. The sensor on the back of my old pixel could also be used to pull down the notification shade which I can't easily reach with one hand, now, since the screen is so large.
I forgot about the gesture to pull down the notification bar. The was far superior. I could reach in to my pocket and have the phone unlocked before I even see the screen
There is a one-handed mode gesture that you can enable. It allows you to swipe straight down on the gesture bar to pull the entire top of the screen down.
Motorola had it right, the sensor was right where my index fingers rested on the back. Unfortunately this isn't "premium" nor "hi-tech" enough to sell phones.
I had a phone with one on the back and currently have one with it on the screen. Personally I had absolutely no issues with its functionality in the screen and do prefer it over the back. I like that I can unlock my phone without having to pick it up off the desk or while its still in the mount on my vehicle dash.
Seems to work perfectly fine to me but maybe it's a quality issues with the brand of phones. Mine is a OnePlus and it's almost 4 years old now, still works fine and never had any issues.
I miss the back fingerprint scanner. I could unlock my phone as I'm taking it out of my pocket . The in screen one on Samsung phones is really unreliable.
My sensor is on the button that turns on the phone, and it's on the right side where the thumb is placed anyway. You press it, phone turns on and you can enter the passkey, you slide your thumb over it, you unlock the phone directly.
I have it deactivated though. There's no need to store my fingerprint anywhere to save 1.5 seconds.
All of the phones I have had have had practically flat fingerprint sensors, For example, the Pixel 3a XL which is closest to me right now has an inwards facing sensor.
