How to manually update Android Auto (and what it might mean if you can’t)

The Android Auto application is available on the Google Play Store and relies on smartphones for its features. It receives updates automatically, but users can manually check for updates if needed. Android 9.0 or higher is required for the latest updates. To force an update, users can reset the app by clearing its storage, which does not affect other apps. If issues persist, users can revert to the original version of Android Auto by uninstalling updates.

Are Free VPNs for Android Actually Worth Using

A free VPN for Android can improve internet privacy, especially on untrusted networks, but it has limitations, such as not guaranteeing complete anonymity or security. The VPN creates an encrypted tunnel between the device and the server, protecting traffic from local monitoring but not ensuring overall security if poorly implemented. Changing your IP address does not guarantee anonymity, as account logins and tracking technologies can still identify users. Free VPNs may be suitable for low-risk tasks, like occasional browsing on public Wi-Fi, but they do not protect against malware or phishing. Providers often rely on alternative revenue sources, such as advertising or data sharing, which necessitates careful examination of their privacy policies. Free VPNs may have limitations like data caps, slower speeds, and fewer server options compared to paid services. Users should evaluate the provider’s background, privacy policy, permissions, and performance before installation. A paid VPN generally offers better reliability, support, and transparency, making it a safer choice for sensitive activities.

4 new ways Android is protecting your network connections

Developers are encouraged to upgrade to OkHttp 5.5.0 and enable Encrypted Client Hello (ECH) for modern networking practices. Android 17 introduces Local Network Protection, requiring apps to obtain user permission before scanning local networks. Android has implemented Certificate Transparency (CT) by default to log all certificates in a public registry, reducing the risk of fraudulent certificates. Scammers are using portable devices known as “SMS blasters” to target mobile users by forcing them onto less secure 2G networks, allowing phishing texts to bypass modern spam filters.

The Truth About Android Antivirus Apps in 2026

Most Android users consider third-party antivirus apps unnecessary due to the robust built-in security features of modern Android smartphones. However, Android devices are still vulnerable to viruses, malware, and security breaches, with a 2025 Gen threat report indicating a tripling of malicious push notifications and an increase in spyware issues. Google Play Protect blocked 27 million malicious apps in 2025 and conducts scans to manage security. Android employs sandboxing, regular security updates, and an opt-in permissions system to protect users. Upcoming features include phone call spoofing protection and enhanced live threat detection capabilities. Social engineering tactics, such as phishing and fake tech support calls, pose significant risks that antivirus software cannot address. Connecting to open Wi-Fi networks can expose devices to risks, and malicious push notifications can mislead users. Third-party antivirus apps may be beneficial in high-risk scenarios, such as public Wi-Fi networks or when sideloading apps, providing an additional layer of protection.

You Can Use Your Old Android Phone As A Universal Remote – Here’s How

Repurposing an old Android phone can enhance home entertainment by connecting it to a smart TV through various methods. Both devices should be on the same Wi-Fi network to use mobile apps like Roku or Amazon's Fire TV remote app. If no official app is available, generic options like Universal TV Remote can be found on Google Play, although they may include ads. Bluetooth connectivity is also an option, exemplified by the Bluetooth Remote app. If Wi-Fi or Bluetooth is not feasible, an infrared (IR) blaster can be purchased to turn the smartphone into a universal remote without needing an internet connection. IR blasters connect via the USB-C port and communicate with the TV's built-in components. Various IR blasters are available, including standard models and more advanced versions that support voice commands. Most Wi-Fi and Bluetooth apps are free, while IR blasters are affordable and widely available.
