Don't Wait for an Under-the-Display Fingerprint Sensor
It's early, but Galaxy Note 9 rumors claim the device will have a feature the iPhone X and Galaxy S9 don't have: A fingerprint sensor under the display.
Synaptics recently announced that fingerprint readers under smartphone displays would become the real deal in 2018 so there's a chance the Galaxy Note series is among the first to use the technology. There's also a chance the Galaxy Note 9 misses this feature.
A recent rumor out of Korea claims the Galaxy Note 9 might not come with this capability. We're unfamiliar with the source, but a source we're very familiar with agrees with this sentiment.
Ming-Chi Kuo, a well-respected analyst from KGI Securities, claims the Galaxy Note 9 is unlikely to feature a fingerprint sensor under the hood.
In a research note Kuo writes that "under-display fingerprint solutions may currently have many technical issues (e.g. screen protectors and different environments affecting recognition rates and power-consumption)."
This doesn't rule it out, but Kuo is a believable source after correctly predicting many of Apple's product launches over the years.
Another credible source, Ice Universe, also claims the Galaxy Note 9 won't come with a fingerprint sensor under the display.
Samsung is reportedly going to make a decision on this soon, possibly by the end of the month, so it might be worth waiting a few more days to see how things shake up.
That said, if authenticating your identity with a simple press on your phone's display sounds like something you're interested in, you might have to wait until 2019 for the Galaxy S10.
