One of my favorite aspects of folding phones is the return of the fingerprint sensors built directly into the power button. This is objectively the ideal design, for reasons I assume I don’t have to explain.
Lately, however, the novelty of folding phones is wearing off and I’m starting to think I’d just like something lighter and sleeker. Are there any recommendations for a phone with a power-button sensor that still has good specs and cameras?
Edit: for the purposes of this post, physical sensors on the back of the phone also count, since they can wake the phone and unlock it simultaneously.
And to clarify (I thought this was a thing everyone just inherently agreed on), the benefits of physical sensors are:
accuracy. A physical sensors will always be more accurate (and thus have fewer issues) because it doesn’t have to work THROUGH the screen. This has been improved a lot with newer technologies like ultrasonic readers, but it is literally impossible to be better than the same technology utilized without a screen in the way.
wake/unlock in one motion. Since it’s also a button, it can wake the phone and unlock it in one motion, rather than 2 separate ones. Again, newer tech has sort of worked around this with things like lift to wake or just having the sensor area ALWAYS scanning so you can unlock it from sleep regardless, but these are clunky software implementations that rely on your phone constantly actively trying to to figure out whether you’re doing the thing or not, so it again can’t be as efficient as just a normal button. Battery impact for these is also pretty minimal for the most part, but it’s still not zero.
tactility. You can feel the button, and manufacturers can put it where your hand naturally rests, meaning that you can unlock the phone BEFORE you have even taken it out of your pocket.
cost. Physical sensors are hella cheap y’all. The technology to read the ridges on your finger through a sheet of plastic and glass is (turns out) kind of expensive. We’re all being forced to pay for this dumb gimmick.
durability. Screens get scratched and dinged up, which compromises the sensors ability to read. Physical sensors on the other hand are basically the most durable part of the phone. Again, mostly a non issue on newer phones, but it’s yet another thing manufacturers have had to dump money into working around (and thus charging you more for).
not impacted by screen protectors, rain on the screen, etc.
I prefer a full-size physical sensor on the back of the phone myself. It tends to be more accurate and faster than the under screen ones I’ve dealt with. No idea about the power button ones. Convenient placement probably. Not sure about performance though.
In my experience rear-mounted sensors are the most accurate, closely followed by under-screen sensors. Side-mounted sensors are utter garbage.
Accuracy isn’t even that much of an issue, it’s that the side-mounted ones are far too easy to accidentally trigger just by handling the phone. I can’t count the number of times my last two phones told me I had three incorrect fingerprint attempts after I had just pulled them out of my pocket.
Then I got a Pixel and I have no more such issues and virtually perfect accuracy. Same on a Samsung tablet. Same on an old phone I had where the power button was on the rear and had a full-size sensor.
Basically, I’m perfectly happy with any front- or rear-mounted full-size sensor. Those tiny side-mounted ones suck.
I loved the rear-mounted sensor on my old Pixel 2XL, as it could be configured to allow some swipe gestures too. I had mine set to open notifications on swipe down, which was really useful.
