Focus will be more on the Video instead of the Camera
Technology : Before 2020, most of the focus of the smartphone's cameras was on 'it captures the picture well', but by 2021 the focus of the smartphone's cameras will be 'This video records well'.
Indication of this, in many smartphones launched in the last quarter of 2020, companies gave you gestures.
As much as the focus on Dolby Vision in the iPhone 12 Series, the Note 20 Ultra also had 8K video recording and manual video shooting mode. At the same time, Vivo's X series was done by giving features such as stabilized video like Gimbal and videos like I Autofocus.
You can see this in almost every second-third smartphone launched in 2021.

In the year 2020, many smartphone companies launched their own smartphones with folding screens. Most of these smartphones are either open like an old claim shell design, or fold up the screen like a book, or strange dual screen phones. Now in 2021, many more designs will be seen in folding smartphones. Which will also have smartphones with Rollable screens.
By design, the Rollable screen will be much better, because the folds of the screen like the book start to appear in the middle of the fold and the phone becomes thicker after folding. There is also a fear of wrinkles in the Clamshell design. This design looks beautiful, but the phone cannot be of the size of a tablet computer in it.
Seeing the concept design of the Rollable screen, it seems that the design will be more 'practical', because the motors inside the phone will cover the screen. Like we roll the chart paper. By pressing a button, the screen will be pulled from 'phone mode' to 'tablet mode'. All this will be done with the help of motors inside the body of the phone. Which will also increase the life of the foldable screen.
