What should we pay attention to in fingerprint sensor tablets?

I got my first fingerprint sensor tablet last year—a Xiaomi Pad 6 Pro—and back then, I only compared its price and display quality. I didn’t think much about the sensor’s everyday use. At first, I felt like a stranger staring at my hand, waiting for it to glide—my reflex hesitated not when looking at the screen, but when pressing the sensor. I quickly learned how easily it could be triggered, even accidentally unlocking my device just by being in my pocket. One time, I didn’t realize I’d turned it off, and while trying to take a photo of my dinner, my phone in my pocket unlocked itself. That’s when it hit me. Now, when checking out newer models, I pay attention to the sensor’s position and placement—having it on the top edge reduces interference from pocket pressure. The brand of the sensor also matters. I once dealt with a cheap local brand that kept giving error messages whenever the lighting changed or my finger was slightly damp. Now, I prefer ultrasonic sensors over optical ones because they work better with wet fingers and different angles. On the software side, I also consider how long the manufacturer supports security updates. My old tablet stopped getting updates after two years, so now I go for brands that promise four years of support. For security, I look for tablets that offer two-factor authentication through both the sensor and the operating system—especially important when using banking apps, where that extra step makes a big difference.
