Don’t Make These Mistakes After Updating Your Android Phone

Keeping system software on Android devices updated is essential for security, bug fixes, and performance improvements. After a significant update, users should review device settings as some may revert to defaults. Clearing the device's system cache and rebooting is recommended to optimize performance, as temporary files can accumulate during updates. To clear the cache, access the Android Recovery menu and select "Wipe Cache Partition." Following an update, it's also important to check for individual app updates in the Google Play Store. Users should verify available storage, as updates can consume significant space, and maintaining at least 10% free storage is advised. If issues persist, rebooting the device in safe mode can help diagnose problems by disabling extra apps and widgets.

Hands on with Windows 11 26H1 and why this update is not meant for your PC

Microsoft has announced Windows 11 26H1, a release intended exclusively for new ARM devices launching in 2026, specifically those powered by the Snapdragon X2 series. This version is not a feature update for existing PCs and will not appear in Windows Update notifications for users on Intel or AMD hardware. Windows 11 26H1 is based on a new internal core designed for ARM silicon, referred to as a "hardware-optimized release," and may carry the codename Bromine. The OS Build number for 26H1 is 28020.1611, distinguishing it from previous updates. Key enhancements include full integration of semantic natural-language search within Settings, an increase in the FAT32 format limit from 32 GB to 2 TB, and UI refinements. Notable omissions include the removal of .NET Framework 3.5 as an optional feature and a safeguard preventing the System Preparation Tool from running in Safe Mode. Windows 11 26H2 is expected later in 2026 for existing PCs.

PromptSpy Android Malware Abuses Google Gemini to Automate Recent-Apps Persistence

Cybersecurity researchers have identified a new Android malware named PromptSpy that utilizes Google's Gemini AI chatbot to enhance its capabilities and persistence on infected devices. PromptSpy can capture lockscreen data, obstruct uninstallation, gather device information, take screenshots, and record screen activity. It integrates Gemini to analyze the current screen and provide instructions to keep the malware active in the recent apps list. The malware uses a hard-coded AI model and communicates with a command-and-control server via the VNC protocol, allowing remote access to the victim's device. It is financially motivated, targeting users in Argentina, and was developed in a Chinese-speaking environment. PromptSpy is distributed through a dedicated website and is considered an advanced version of a previously unidentified malware called VNCSpy.

Fix: UAC “Yes” Button Missing in Windows

The "User Account Control (UAC) Yes button missing" issue occurs when a user with a standard account attempts to authorize an action requiring administrator approval, resulting in the absence of the Yes button. To resolve this, the built-in Administrator account can be enabled by accessing Safe Mode and running the command PLACEHOLDER41726aa2dbf8cb10. After restarting, the user can log into the Administrator account, which has full privileges, and then grant administrator rights to their main account by using PLACEHOLDERd2270d55f540aab4 to change the group membership. After the main account is granted admin rights, the Yes button should appear in UAC prompts. It is recommended to disable the built-in Administrator account afterward for security by running net user administrator /active:no. If the device is managed by an organization, the user should contact their IT department for assistance. As a last resort for personal PCs, if no admin account is available, the user may need to reset or reinstall Windows after backing up important files.
