Korean tech giant Samsung came under fire for its high-end Galaxy Note 10 and S10 flagships earlier this month, after it was reported that the devices' ultrasonic fingerprint sensor can be fooled through using gel-based screen protectors. For devices that use this sensor to make financial transactions, it's a huge discovery, and Samsung has started to roll out updates that will fix the problems.
