In a matter of weeks we might be seeing the Galaxy S21 series being launched but different rumors surfacing online are giving insights about what to expect when the device finally make it out.

For example, one of the most recent has it that that there will be three Galaxy S21 series which will include the Galaxy S21 5G, S21+ 5G and S21 Ultra 5G by January 14th which is much more closer than expected.

The most interesting is that there have been some official teasers which are already appearing online and now a tipster states the device will have an improved under-display fingerprint sensor.

For the records, Ice Universe is a popular leaker online and with his recent tip, he state that Samsung has improved its popular Ultrasonic Fingerprint sensor for the Galaxy S21 series.

He also said this will be a major upgrade from the Galaxy S10 series back in 2019 which is based on the Qualcomm’s Ultrasonic fingerprint technology at the launch of the S10 series.

There are two popular under display scanners nowadays which are optical and ultrasonic. The latter uses sound-wave to read fingerprint and its integrated within the display and once its touched, the pressure of the finger will send an electric pulse which will nudge the 3D Sonic Sensor that reads and also authenticate the fingerprint.

With the new improvement based on the leaks, the Galaxy S21 will be a 8*8=64mm.

Anyway, considering fingerprint is a necessary feature, Samsung will mostly include the same fingerprint across models. However, we will have to wait and see the real-world testing to believe these early claims.

Another thing is the expectation of the next-gen Exynos 2100 chipset which will probably powers the Galaxy S21 series. At least the in some regions even if not on the flagship.

That is a 6.2-inch FHD+ display and 4,000mAh battery on the former, and a 6.7-inch FHD+ display and 4,800mAh battery on the latter.

Other cool interesting things that will probably be seen on the next-gen S21 Ultra will be the QHD+ 120Hz display and of course retaining the massive 108MP sensor coupled with other secondary sensors.

As far as the power is concerned, we might see a massive 5,000mh battery on the device and the much rumored S-Pen which is usually exclusive to the Galaxy Note series.
