Two months in the past, I reluctantly switched to the Galaxy Z Fold 7.
It was a call overwhelmingly motivated by software program, with Samsung’s One UI 8 providing some key options that helped me tame my doomscrolling.
However the anticipated compromises in comparison with non-folding smartphones weren’t notably interesting, together with the lack of an under-display fingerprint sensor.
The twin-screen design of book-style foldables makes this extremely impractical, with the Galaxy Z Fold 7 integrating a bodily one into the ability button as a substitute.
Nevertheless, removed from being a downgrade, the fingerprint sensor has made unlocking my telephone, logging into apps and authenticating funds a breeze. In comparison with my rage-inducing expertise with some under-display variations, it’s been a breath of recent air.

It’s prompted a wider query: when bodily sensors are nonetheless so significantly better, why are we persisting with under-display ones? Within the eight years since they had been first launched, progress has been extremely gradual.
After utilizing the Galaxy Z Fold 7 for greater than a few months, I’m satisfied that it’s time to ditch under-display fingerprint scanners on all telephones – not simply foldables and cheaper fashions. Listed below are 5 key explanation why.
Beneath-display sensors are merely not ok
If under-display fingerprint scanners had been simply as quick and dependable as bodily ones, there’d be no contest. The comfort of getting it proper there in entrance of you is unmatched.
However that couldn’t be farther from actuality.
As somebody who’s reviewed dozens of Android telephones in the previous couple of years, I’ve examined greater than my fair proportion of scanners. Reliability varies massively, with some unlocking my telephone lower than half the time and others nearer to 90%. However my message is obvious: you may’t belief them.
…in case your fingers are a bit sweaty, or god forbid, you spill water in your display screen, you may mainly overlook about entering into your telephone

Additionally, in case your fingers are a bit sweaty, or god forbid, you spill water in your display screen, you may mainly overlook about entering into your telephone. These points have been happening for years, however in my expertise, no firm has correctly addressed them.
Ultrasonic scanners are typically quicker and extra dependable than optical, however I’ve had loads of points with these, too. I merely can’t depend on them, particularly if I have to get into my telephone shortly.
It additionally proves a serious headache when authenticating funds, logging into apps and even accessing passwords. This sub-par expertise is a daily ache level every time I exploit an Android telephone, and I don’t see that altering anytime quickly.
Apple’s snub speaks volumes
Given these points, it’s maybe no shock that Apple has completely prevented under-display fingerprint sensors to date.
After ditching the Contact ID bodily fingerprint scanner on the entrance of the iPhone in 2017, Apple changed it with a safe 3D face unlock technique referred to as Face ID. The remaining, as they are saying, is historical past.
However somewhat than coming late to the celebration with a greater under-display fingerprint sensor (as is usually the way in which) down the road, Apple has prevented ever introducing one.
When Face ID offers a quick, safe various that works even at nighttime, there’s little incentive to complement it with a subpar various

It’s clear that they’ve by no means reached the standard required for Apple to introduce it. When Face ID offers a quick, safe various that works even at nighttime, there’s little incentive to complement it with a subpar various.
When Apple launched an up to date model of Contact ID for some iPad fashions, it selected to combine it into the ability button somewhat than underneath the show. It aligns with the corporate’s long-standing ‘it simply works’ motto, which definitely can’t be stated for in-screen scanners.
Apple isn’t proper about every little thing, after all, however I feel the Android telephone market actually must comply with its lead right here.
Safe face unlock is extra standard than ever
The truth that the iPhone has by no means had an under-display fingerprint sensor speaks to the efficacy of recent face unlocking strategies.
Face ID goes far past a fundamental face unlock, which may typically be fooled by pictures or individuals with the same look (reminiscent of twins). As an alternative, it makes use of an infrared digital camera to challenge hundreds of dots onto your face to create an in depth map, making it far more safe and dependable.
For a very long time, this was the one face unlock of its sort on smartphones, however Android telephone makers are lastly beginning to catch up.

The likes of the Honor Magic 8 Professional and Oppo Discover X9 Professional utilise comparable know-how to Apple. Google’s strategy because the Pixel 8 is barely totally different, however nonetheless safe sufficient to interchange fingerprint scanners for logging into banking apps and authenticating funds.
With extra choices popping up on a regular basis, it’s doable that fingerprint scanners of all kinds might turn out to be out of date on telephones quickly. And within the meantime…
Bodily scanners could be impressively discreet
A decade in the past, in case your telephone had a fingerprint scanner, the entire world knew about it. The iPhone’s Contact ID stared at you within the face from beneath the display screen, whereas the likes of LG, Motorola and Samsung tried varied positions on the again.
Understandably, this distinguished design was divisive, flying within the face of a minimalist aesthetic. However the days when this was mandatory are lengthy gone.

For a few years, corporations have been integrating their fingerprint sensors into the ability buttons, permitting them to seamlessly mix into the telephones’ designs. As a bonus, it’s typically situated the place you’d naturally relaxation your finger anyway, avoiding the necessity for any finger gymnastics to succeed in it.
I don’t anticipate anybody to ditch the ability button anytime quickly, that means it’s a legitimate long-term choice that fades into the background if you don’t want it. Against this, under-display scanners are sometimes a lot tougher to disregard.
There’s important cost-saving potential
In 2026, pricing is a scorching subject on telephones. The continuing world RAM scarcity, pushed by enormous demand from AI datacentres, is driving up costs and placing enormous strain on producers.
Consequently, we’ve seen many telephones launch with elevated worth tags, very minimal upgrades, or each. In Samsung’s case, it might even increase costs on fashions which can be already out there.

Firms are looking out to economize on manufacturing prices wherever they’ll. Ditching under-display sensors for his or her bodily counterparts is a straightforward manner to do that, with Intel Market Analysis suggesting it’s 25-30% cheaper.
Making this straightforward swap would enable corporations to avoid wasting important cash whereas upgrading the general expertise. It’s a no brainer.
The sunk-cost fallacy
Eight years after they had been launched, under-display fingerprint sensors proceed to flatter to deceive. Whereas they’re slick and extremely spectacular once they work, all too typically they’re beset with reliability points that power individuals to search for options.
With nice options out there within the type of bodily sensors and safe face unlocking strategies, there’s no have to stick with a know-how that’s dearer and fewer reliable.
I completely perceive the attraction, and it was solely proper for producers to experiment for just a few years. Nevertheless it’s clear that the know-how goes nowhere quick, so now’s the time to surrender.
If under-display fingerprint sensors do ever get phased out, I definitely gained’t be mourning their loss when the options make a lot extra sense.
