In what’s being labeled one of the most urgent security updates in recent Android history, Google’s April 2025 Android Security Bulletin has brought to light a string of critical vulnerabilities impacting millions of users — with particular implications for Pixel and Samsung devices. While updates are a monthly ritual for Android, this one has raised eyebrows due to the severity of the security threats, their active exploitation, and buggy aftermath affecting essential features like Google Assistant.

The disparity in how and when Android manufacturers deliver security updates has long been a point of concern, but the April 2025 update has made it impossible to ignore. With zero-day exploits now being weaponized faster than ever, the need for a universal Android security framework is becoming a critical talking point among industry experts.
Analysts argue that Google must implement a more centralized update mechanism — one that ensures all Android users receive critical patches within the same timeframe, regardless of brand or carrier. Until then, billions of devices remain vulnerable due to a fragmented update ecosystem that prioritizes design overlays over defense.
62 Security Vulnerabilities, Two Zero-Days Already Exploited
Google confirmed that 62 security vulnerabilities have been patched in this month’s update — a staggering number in itself. But two flaws, CVE-2024-53150 and CVE-2024-53197, are especially alarming.
These zero-day vulnerabilities were already being actively exploited in the wild, meaning hackers and even government bodies were leveraging them before Google could roll out a fix. The most concerning? CVE-2024-53197, which reportedly allowed bypass of lock screen security measures — a vulnerability so severe it enabled full access to devices without a passcode.
According to reports, Serbian law enforcement authorities used this flaw in real-world investigations to extract data from confiscated Android phones, sparking a debate about government surveillance and user privacy.
Devices Patched Instantly, Samsung Faces Delays
As expected, Google’s own Pixel line of smartphones received the April update as soon as the bulletin dropped. However, users of Samsung phones, despite making up a massive portion of the Android user base, are once again left in the dark.
Samsung’s updates are often bottlenecked by manufacturer-specific software layers and regional carriers. As a result, many Samsung devices remain exposed to critical vulnerabilities even days or weeks after Google’s initial release. This puts millions of users at unnecessary risk, especially those unaware of the delay.
Experts warn users to manually check for updates regularly and avoid using sensitive apps or services until the security patch is available on their devices.
Google Assistant Bug Causing Missed Alarms, Calls & Notifications
Adding fuel to the fire is a newly discovered bug in Google Assistant, which is affecting the Do Not Disturb (DND) functionality. When users activate DND using voice commands like “Hey Google, turn on Do Not Disturb,” the Assistant overrides user-defined exceptions — silencing everything, including important calls, alarms, and reminders.
This issue has already led to reports of missed appointments, delayed responses to emergencies, and missed school or work obligations. The bug appears to be affecting Pixel users the most, but Android devices that rely on Google’s core Assistant framework may also be impacted.
As a temporary workaround, Google recommends manually setting DND via Settings > Sound & vibration > Do Not Disturb, until a permanent fix is rolled out.
Why This Update Matters More Than Ever
This isn’t just another routine patch. These vulnerabilities and system-level bugs hit at the very core of what users expect from modern smartphones — privacy, reliability, and consistency. The implications of such vulnerabilities go beyond convenience — they pose serious threats to:
- Personal and enterprise data security
- National cybersecurity, especially with foreign authorities already exploiting these flaws
- Public trust in Android’s open ecosystem
Moreover, the Android fragmentation problem remains a sore point. While Google acts quickly, its partners — including the largest manufacturer, Samsung — often struggle to deliver updates at the same pace, exposing users for longer than necessary.
What Android Users Should Do Right Now
- Check for Updates Manually
Go to Settings > System > Software Update and install the April 2025 patch if available. - Avoid Voice Activation for DND
Until the Assistant bug is resolved, manually activate Do Not Disturb via your phone’s settings. - Stay Cautious with App Permissions
Be mindful of apps requesting access to files, contacts, location, and background activity. - Use Google Play Protect or Antivirus Apps
Additional layers of security can help reduce risk, especially on devices waiting for updates. - Follow Official Channels for Fix Announcements
Subscribe to Google’s and Samsung’s support pages or Twitter handles for immediate alerts.
The Bigger Picture
This Android update marks a critical moment for both Google and the entire Android ecosystem. While Google’s responsiveness is commendable, the situation has once again highlighted the need for more unified and faster rollout strategies, especially when dealing with actively exploited security threats.
Users, especially those on Samsung devices, should not have to wait days for basic protections. And while Android’s flexibility is a core strength, its fragmented software delivery remains a liability in times of crisis.
As Android 14 continues to evolve, and Android 15 looms later in the year, Google and its partners must prioritize security parity across devices — not just features.
