Some speculations from this teaser:

• Gorilla Glass Protection is said to be on front side only and device is going to be lighter. This might mean that upcoming #RedmieNote10 Series devices may ditch the long-running glass back panel design and feature polycarbonate (plastic) back panel instead.

• If you observe the pics in the teaser properly then you can see that 2 different devices are shown. One having a side-mounted fingerprint sensor & the other doesn't.

In today's date, even mid-range devices have mostly shifted to side-mounted fingerprint sensor instead of having it on the back.

One device having a normal power button instead of side mounted fingerprint sensor might mean that it has under display fingerprint sensor, which further implies that it has AMOLED Display panel.
So, atleast one device of #RedmiNote10 Series might feature AMOLED Display panel.

Again, all these speculations could be wrong if the images used in the teaser are for illustration purpose only and not the actual devices.

This teaser suggest that Redmi is doing away with their glossy gradient "AURA" back design and evolving towards unicolor "EVOL" back design.

Generally, Xiaomi gives glossy gradient back design to it's glass back smartphones & unicolor design to it's polycarbonate back smartphones.

This further fuels the speculations that the upcoming #RedmiNote10 Series will feature polycarbonate back panel instead of glass.
