With the release of Android 15, Google has made a significant improvement by introducing true adaptive refresh rate (ARR) support, which optimizes the screen refresh rate on Android devices.

This feature aims to reduce power consumption and improve user experience by dynamically adjusting the refresh rate of the screen according to the content. LTPO displays on Android devices use preset staggered modes to deliver variable refresh rates, typically between 1 Hz and 120 Hz. However, these displays do not offer a seamless VRR experience like on PCs by matching the refresh rate with constantly changing frame rates. Before Android 15, the software framework only allowed switching between certain modes, which limited the expected smooth transitions and high responsiveness, especially in games.

Upgraded Implementation of ARR on Android 15

In Android 15, Google introduced true ARR support with updates to the Hardware Composer (HWC) hardware abstraction layer. The new HWC HAL v3 enables the display to optimize the refresh rate according to the content type, without switching between different modes. This improvement aims to deliver smoother transitions by reducing “jank” or visual stuttering.

Hardware Compatibility and Limitations

Full use of ARR requires new hardware and powerful devices like Snapdragon 8 Elite. with processors Requires devices with incoming HWC HAL v3 support. Older devices may not benefit from ARR due to lack of hardware or kernel support, even if they receive the Android 15 update. Additionally, Google’s ARR approach doesn’t provide game syncing like on PCs; it only allows the tearing effect of the panel to match certain speeds.

ARR support offered in Android 15 is seen as a big step towards providing a more dynamic and energy efficient display experience. However, widespread use of this feature will depend on hardware compatibility and device manufacturers’ adoption of HWC HAL v3, which may limit ARR primarily to new flagship models.

DeX App is Removed with Samsung One UI 7

Samsungnew OneUI 7 with update DeX announced that it will discontinue its application for Windows.

DeX was a feature that allowed Galaxy phone users to get a desktop-like experience by mirroring their devices to a PC screen. However, with Samsung’s latest update, DeX support for Windows will end as of One UI 7. Instead, users are encouraged to connect their phones and computers through the “Connect to Windows” feature.

This change is considered as Samsung’s effort to offer a more integrated and flexible solution. The “Connect to Windows” feature is not limited to Samsung devices only, it works with a wider ecosystem. In this way, users can provide a more seamless connection between different devices.

Other Changes: Removal of Third Party Panels

Samsung also plans to remove support for downloading third-party edge panels with One UI 7. This step aims to make the system more stable and faster while simplifying the user interface. However, these changes may impact usual workflows for some users.

Although not much information has been shared about One UI 7 yet, leaks design and indicates that there may be significant changes in properties. New icons and interface improvements aim to improve the user experience. However, the removal of DeX and the end of support for third-party panels may affect some users’ satisfaction with the platform.

It is important for Galaxy users to pay attention to these changes while preparing for the One UI 7 update. DeX app discontinuation may require them to change the way they connect their phone to the PC. Also, if you are using third-party panels, it is worth considering removing this support.

Bootkitty: Linux Users Are Targeted

Security researchers have discovered the first UEFI bootkit designed for Linux systems, dubbed Bootkitty by its creators. This discovery is the first evidence that UEFI boot kits are no longer limited to Windows systems.

An abbreviation for Unified Extensible Firmware Interface. UEFIis known as motherboard control software. UEFI is software that is activated when the computer starts, before the operating system starts.

If cybercriminals change the UEFI code, they can use it to deliver malware to the victim’s system. Bootkit It is defined as a type of malware designed to gain low-level control over the computer without the owner’s knowledge.

bootkitty

After a previously unknown application named bootkit.efi was uploaded to VirusTotal in November 2024, Security researchers discovered that it was a UEFI application.

After in-depth analysis, it confirmed that it is a UEFI boot kit called Bootkitty by its creators; surprisingly, it is the first UEFI boot kit to target Linux specifically several Ubuntu versions. The bootkit contains many artifacts that suggest this is more of a proof of concept than the work of a threat actor.

bootkitty

Bootkitty is signed with a self-signed certificate, so it cannot run on systems that have UEFI secure boot enabled by default. But since Bootkitty patches in memory the necessary functions responsible for integrity verification UEFI It is designed to seamlessly boot the Linux kernel whether secure boot is enabled or not.

Bootkit is an advanced rootkit that can replace the boot loader and patch the kernel before it is executed. Bootkitty gives the attacker full control over the affected machine as it hijacks the machine’s boot process and runs the malware before the operating system even starts.

During analysis he discovered a possibly related unsigned kernel module that he called BCDropper, with signs suggesting that it may have been developed by the same authors as Bootkitty. It distributes an ELF binary responsible for loading another kernel module, unknown at the time of analysis.
