How to make sure your Android phone is secure

Android devices have various features to enhance security and privacy. A 2025 Pew Research Center study found that nearly 75% of Americans have faced online scams, which have become more sophisticated, including vishing scams using AI-generated deepfakes. Android offers tools to mitigate these risks, such as AI-driven scam detection and theft protection. To safeguard devices, users should keep their software updated by checking Settings > About Phone for the current version and navigating to Settings > System > Software Updates for updates. App updates can be managed through the Google Play Store under Settings > Network preferences > Auto-update apps. Securing Google accounts with two-factor authentication is recommended, which can be set up via the Google Account management page. Automatic backups can be enabled in Settings > Google > Backup. The Find Hub app helps track lost devices and can be configured in Settings > Location and Settings > Security. Android includes scam detection tools that alert users to potential scams in calls and texts, which can be activated in the Phone app settings. Privacy settings can be managed by adjusting app permissions in Settings > Apps and using the Permission manager in Security & Privacy. Users can opt out of data sharing with advertisers by navigating to Settings > Google > Ads. Google Play Protect scans for harmful apps and should remain enabled for safety. Theft protection features, such as Theft Detection Lock and Remote Lock, can be activated in Settings > Google > Personal & device safety.

New JK Terror Tactic: Pornography Apps, Tor Network Used For Secret Messaging

Security agencies in India have observed a shift in the tactics of terrorist groups, which are now using pornography websites and niche encrypted applications for communication instead of traditional social media. These groups, often collaborating with Pakistan's ISI, utilize platforms with real-time chat tools disguised as dating services to send instructions to recruits in Jammu and Kashmir. Security agencies are monitoring various digital tools, including Tor-based applications like Coatex and Conion, which obscure user identities. Some privacy-focused platforms do not require phone numbers for registration, complicating tracking efforts. Despite bans on certain pornography applications in India, they are still accessed illegally via VPNs, which mask users' IP addresses. The use of the Tor network presents additional tracking challenges, as it obscures data origins and destinations. Security agencies are adapting their surveillance methods in response to these developments, which include the use of virtual SIM cards in terrorist activities, as highlighted during investigations into the 2019 Pulwama attack.

Z-TEXT, a zk-SNARKs Blockchain Messenger, Launches Channels, Completing a 4-in-1 Privacy App on BitcoinZ

Z-TEXT has launched its Channels feature, transforming its platform into a comprehensive 4-in-1 privacy ecosystem built on the BitcoinZ blockchain. This system features a four-layer security architecture, including local device encryption, zk-SNARKs shielding, BitcoinZ blockchain settlement, and post-quantum protection. The Channels feature allows creators to maintain control over their broadcasts, with subscribers connecting directly through their wallets, ensuring no central authority can seize or delete subscriber information. Users can restore their channel and its history on any new device using a 24-word seed phrase. Z-TEXT emphasizes the importance of permanence in privacy, contrasting with the trend of automatic message deletion. The application requires no phone number, email, or SIM card for identity verification, relying solely on the 24-word seed phrase. Z-TEXT has been in closed beta without critical vulnerabilities and is preparing for public release on major app stores. The average message fee is approximately [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Z-TEXT, a pioneering zk-SNARKs blockchain messenger, has recently unveiled its innovative Channels feature, marking a significant evolution in its privacy-focused ecosystem. Built on the BitcoinZ blockchain, Z-TEXT is designed with a robust four-layer security architecture that includes local device encryption, zk-SNARKs shielding, BitcoinZ blockchain settlement, and post-quantum protection. The Shift to a 4-in-1 Privacy Ecosystem This launch signifies Z-TEXT's transformation from a conventional messaging platform to a comprehensive 4-in-1 privacy ecosystem. In this new paradigm, users' interactions are securely housed within their wallets rather than in centralized company databases. As Eric Pierrot, the founder of Z-TEXT LLC, aptly notes, "Needing to disappear is proof you can't survive the erosion of time—or what's coming with quantum computing." The Channels feature empowers creators by allowing them to maintain control over their broadcasts. Each subscriber connects directly to the channel through their own wallet, eliminating the risk of a central authority seizing, selling, or deleting subscriber information. This decentralized approach ensures that the integrity of the channel remains intact, regardless of external pressures. Subscribers can receive messages from the broadcaster at a fixed cost, whether the audience comprises ten or ten thousand individuals. In the event of a lost device, users can effortlessly restore their channel and its complete history on any new device using the same 24-word seed phrase that secures their entire account. A Commitment to Privacy and Permanence The launch of Channels builds upon Z-TEXT's commitment to privacy, a principle the company has championed since releasing its privacy manifesto on IPFS and timestamping it on the BitcoinZ blockchain earlier this year. While many messaging applications promote automatic deletion as a feature, Z-TEXT argues that true privacy is rooted in permanence. Pierrot emphasizes, "If your encryption actually holds, the message doesn't need to vanish to stay safe. Eternal memory is our signature—we built for permanence, not for disappearing." Having successfully navigated a closed beta phase without any critical vulnerabilities reported through its on-chain bug bounty program, Z-TEXT is now gearing up for a public release on major app stores, including Google Play and the Apple App Store. The application requires no phone number, email address, or SIM card, with identity verification based solely on a 24-word seed phrase. In addition to its messaging capabilities, Z-TEXT integrates a password manager and a crypto wallet, all while maintaining an impressively low average message fee of approximately [cyberseo_openai model="gpt-4o-mini" prompt="Rewrite a news story for a business publication, in a calm style with creativity and flair based on text below, making sure it reads like human-written text in a natural way.

The launch completes Z-TEXT's shift from messenger to a 4-in-1 privacy ecosystem, where audiences live in subscribers' wallets, not company databases. Needing to disappear is proof you can't survive the erosion of time—or what's coming with quantum computing.”— Eric Pierrot, founder of Z-TEXT LLCSHERIDAN, WY, UNITED STATES, July 11, 2026 /EINPresswire.com/ -- Z-TEXT, a zk-SNARKs blockchain messenger, built on BitcoinZ, has launched Channels, a broadcast feature where the creator—not a platform—controls the channel. Each subscriber holds their own connection to the channel in their own wallet, so there is no central list a company can seize, sell, or delete. Channels joins Z-TEXT's existing privacy ecosystem of shielded messenger, password manager, and crypto wallet, all accessible through a single 24-word seed phrase.A single Channels transaction reaches any number of subscribers, from ten to ten thousand, at the same fixed cost. No company sits between the broadcaster and the audience with the ability to suspend the channel or hand over the subscriber list. If a device is lost, the channel and its full history can be restored on any new device using the same 24-word seed phrase that recovers the rest of the account.The launch extends a position Z-TEXT has held publicly since June, when the company published a privacy manifesto on IPFS and timestamped it on the BitcoinZ blockchain, arguing that permanence, not disappearing messages, is the stronger privacy guarantee. Most messaging apps market automatic deletion as a safety feature. "Needing to disappear is proof you can't survive the erosion of time — or what's coming with quantum computing," said Eric Pierrot, founder of Z-TEXT LLC. "If your encryption actually holds, the message doesn't need to vanish to stay safe.

The application requires no phone number, email address, or SIM card; identity is derived from a 24-word seed phrase. Z-TEXT combines a shielded messenger, password manager, crypto wallet, and channels in one application, with message fees averaging approximately $0.00003 per message.

How Your Location Influences Android App Availability

The Google Play Store customizes its app offerings based on the user's location, which affects app availability and functionality. App developers often set distribution rules that vary by region, leading to differences in user experience even for identical apps. Android devices determine location through a combination of signals, including SIM card data, GPS, and Wi-Fi positioning. Connectivity issues, particularly in rural areas, can limit app usability, while social habits influence regional app demand. Developers analyze engagement data to adapt their offerings based on regional preferences, creating a feedback loop that affects app visibility and features. Users should verify app functionality based on their location and connectivity before assuming an app's absence is due to obscurity.

Over 200 Fake Android Apps Are Quietly Stealing Money From Phone Bills

Zimperium identified a sophisticated malware campaign that exploited nearly 250 Android applications, posing as popular games and social media platforms. The malware ensnared users into premium subscription services without consent, using techniques like JavaScript injection and interception of one-time passwords. The campaign primarily targeted users in Malaysia, Romania, Thailand, and Croatia, with the malware capable of reading SIM cards and activating for specific mobile carriers. Zimperium first detected the scam in March 2025 and monitored it until at least January 2026. Google stated that none of the compromised applications were available on its app store and emphasized that Android users are protected by Google Play Protect. The hackers deployed three malware variants, with the first using an automated subscription engine, the second targeting users in Thailand with premium SMS messages, and the third combining SMS fraud with real-time notifications to attackers via Telegram. The campaign primarily affected Malaysian SIM card users, with significant activity also in Thailand and Romania. Despite the campaign's last known activity in January, parts of its infrastructure remain operational. The attacks highlight vulnerabilities in application security and the challenges of policing app downloads from third-party marketplaces.
