Samsung introduces Multi Control feature with One UI 5.1, are you ready?

One UI 5.1 is official, thanks to Samsung’s new Galaxy S23 smartphone lineup. Since the update is yet to release for older Galaxy devices, we are closely exploring all the awaited features. It’s clear that Samsung will roll out the Multi Control feature with One UI 5.1 for Galaxy phones.
As showcased during the Unpacked, the Samsung Multi Control feature allows you to control your Galaxy smartphone, Galaxy Tablets, and Galaxy Book PC directly from the Galaxy Book3 series’ keyboard and trackpad. This capability enables you to copy, paste, or drag and drop between devices.

Benefits of Multi Control
Samsung usually brings additional benefits to connected experiences across the Galaxy S lineup of smartphones. The new Multi Control feature connects mouse and keyboard functionality between a Samsung Galaxy PC and tablet to serve ultimate flexibility between devices.
Besides this, enhanced text usability makes it easy to copy and paste text, like URLs, from one device (smartphone) to another (Tab / PC) to pick up activity on another device. There are more new features in the One UI 5.1 software, check them out right here.
Additional notes
To use the Samsung Multi Control feature, your Galaxy smartphone needs to run the latest One UI 5.1 software. However, consumers having Galaxy Tab running One UI 4.1 or later and Galaxy Book launched in 2021 and later can also enjoy the Multi Control.
Notably, Galaxy users are required to sign in with the same Samsung Account on both phones and PC. There are fewer chances of the expansion of this feature to non-Samsung laptops. Hence, you are lucky if owned a Galaxy Book as Samsung is greatly enhancing the ecosystem.

Samsung Galaxy S23 Light Mode
Galaxy S23’s Light Mode function improves heat generation and current consumption by partially adjusting the AP’s maximum processing speed. It is difficult to experience the Normal mode in normal usage environments such as surfing the Internet, SNS, making calls, and watching videos even if you use the light mode.
It does not reduce the refresh rate of the screen like power saving mode, rather the screen refresh rate remains constant when it is set, so you will not have any inconvenience in using it.
Also, Light Mode has no effect on running games instead it minimizes heat generation and uses battery efficiently.
How to enable Light Mode?
You can easily enable the Light mode feature on your eligible Galaxy devices. Just need to visit Settings >> Battery & Device Care >> Battery >> Other Battery Settings >> Select Performance by Usage Type >> Select Light Mode. You can also add Light Mode to the quick panel to easily turn it on/off it.
