How to Stop Android Battery Optimization from Killing Apps

Users and developers managing Android devices must navigate the balance between battery life and app functionality. Android's aggressive power-saving features can mute notifications or suspend background processes, leading to a state known as “sleeping.” To maintain app functionality, users can exempt specific applications from battery optimization through the Settings app under “Battery” or “Apps & notifications.” This feature, introduced in Android 6.0 Marshmallow, allows apps to operate seamlessly in the background. For example, disabling sleep mode for essential apps like WhatsApp can prevent missed notifications. Samsung's Adaptive Battery is particularly aggressive, often pushing unused apps into a “deep sleep” state after a few days, which can disrupt vital functions. Users may need to manually exempt applications in Samsung’s “Device care” settings. Other manufacturers like Huawei and Xiaomi impose similar restrictions, while Google’s stock Android offers more straightforward adjustments. Developers can incorporate foreground services or request permissions like “android.permission.WAKE_LOCK” to keep apps awake, balancing user privacy and battery health. Android’s Doze mode activates during inactivity and organizes background tasks into maintenance windows, but apps can request exemptions. Monitoring battery usage statistics can help identify problematic apps. In enterprise environments, tools like Ivanti’s mobile device management can automate these settings. Combining exemptions with notification settings ensures that apps remain active, although blanket exemptions may lead to faster battery depletion. The dynamic between operating system efficiency and app demands continues to evolve, particularly with Android 14’s enhanced foreground service requirements.

The Tor Project quietly launches a beta Android VPN – and looks for testers

The Tor Project has launched a VPN app for Android users, currently in beta, aimed at enhancing online privacy and circumventing censorship. The app is available on the Google Play Store and operates under an open-source model. It routes user traffic through the Tor network to conceal real IP addresses and features split tunneling, allowing users to select specific applications for Tor traffic. The app is built on advanced infrastructure using Arti, the Tor Project's next-generation implementation, and includes built-in bridges to disguise Tor traffic. Users are cautioned against using the beta version if they face severe surveillance threats, as it is primarily a testing platform.

These 20 free VPNs with 700 million downloads all have the same problem

Recent research has identified that 20 free VPN applications on Google Play share the same underlying code and a common vulnerability that compromises user data encryption. The study, conducted by researchers from Bowdoin College and Arizona State University, analyzed these apps, which have over 700 million downloads and generate revenue through ads while offering minimal value to users. Notable VPNs included in the study are Tetra VPN, VPN PotatoVPN, and VPN Proxy Master. These applications may mislead users into thinking they have diverse options, but they provide a uniform experience. Additionally, there are concerns about potential vulnerabilities that could expose private data and possible ties to China, a country known for weak privacy protections. The examined VPNs include Turbo VPN, VPN Monster, Snap VPN, and others. In contrast, established VPNs like Proton VPN and NordVPN are noted for their reliability and security.

Russia targets WhatsApp and pushes new ‘super-app’ as internet blackouts grow

Marina, a 45-year-old freelance copywriter, has experienced disruptions in WhatsApp and Telegram services due to new restrictions by Roskomnadzor, affecting communication for millions of Russians. The restrictions coincide with the launch of a state-sponsored app called Max, which is being promoted heavily and is required to be pre-installed on devices sold in Russia as of September 1. Max is designed to integrate various services, including government and banking, similar to China's WeChat, but raises privacy concerns due to its data-sharing policies. In addition to app restrictions, many regions in Russia are experiencing regular mobile internet outages, justified by the government as protection against potential drone attacks, but criticized by experts. The Kremlin's tightening control over internet freedoms has been ongoing since 2012 and intensified following the invasion of Ukraine. The government is working on a plan to limit online access to essential services during outages, further increasing control over the population's digital activities.

Russia promotes ‘national messenger’ to vanquish WhatsApp in fresh crackdown

Russian government minister Maksut Shadayev expressed concerns to President Vladimir Putin about foreign messaging apps like WhatsApp and proposed creating a "fully Russian messenger." Putin supported this idea and signed a law establishing a national messenger service, granting the status to the app Max, developed by VKontakte (VK). Roskomnadzor has begun restricting services like Telegram and WhatsApp due to their involvement in harmful activities, marking a significant effort to limit online freedoms since Russia's invasion of Ukraine in 2022. Digital rights activists worry Max could facilitate government surveillance as it lacks end-to-end encryption, allowing data storage on VK's servers and sharing with law enforcement. Max's user base grew from 1 million to 30 million following a marketing campaign, and schools are now required to use it for official communications. Putin's administration is working to limit software from countries deemed unfriendly, putting WhatsApp's future in Russia in jeopardy. The status of Telegram remains uncertain, as the state has previously attempted to ban it but now utilizes it for communication. Recent legislation has criminalized searching for "extremist materials" and mandated migrant workers to install a surveillance app.

Popular Android VPN apps found to have security flaws and China links

A report by researchers at the University of Toronto’s Citizen Lab and Arizona State University reveals significant vulnerabilities in several Android VPN applications on the Google Play Store, indicating that many are owned by a Chinese company and mislead consumers about their ownership. The study analyzed the 100 most-downloaded VPNs not based in the U.S. and identified three families of providers with shared technical infrastructures and security flaws. Family A includes eight VPNs linked to providers like Innovative Connecting, which have a hard-coded key for Shadowsocks, allowing eavesdroppers to decrypt communications. Family B consists of six providers, including Global VPN, also using hard-coded passwords for Shadowsocks, raising concerns about anonymity. Family C includes providers like Fast Potato VPN, vulnerable to traffic manipulation attacks. The researchers suggest that the obscured ownership of these VPNs may be a strategy to mitigate reputational risks. They also highlight the responsibility of platforms like Google to vet the security of applications, noting that hosting insecure apps could damage Google's reputation. Users are advised to conduct thorough research and choose reputable VPN services.

Citizen Lab Exposes Hidden Ties in 20 Android VPN Apps with 700M Downloads

Researchers from Citizen Lab discovered that over 20 popular Android VPN applications, collectively downloaded 700 million times, are interconnected through undisclosed ownership ties. These applications, marketed as independent privacy solutions, share codebases, servers, and encryption vulnerabilities. The VPN providers are categorized into three families linked to a Russian entity, a Chinese company, and another with ambiguous origins. Apps like Turbo VPN, X-VPN, and UFO VPN share cryptographic keys and backdoors, increasing the risk of man-in-the-middle attacks. Many applications use outdated encryption methods, making it easy for attackers to decrypt user traffic. Some apps route user data through servers in jurisdictions with lax privacy regulations, exposing sensitive information. The investigation revealed identical backend infrastructures among different apps, despite claims of no-log policies, breaching user trust. Hidden trackers within the apps contradict their privacy assurances. Regulators are beginning to respond, with Google removing problematic apps and the EU considering stricter data access regulations. Experts recommend choosing vetted, paid VPN services that undergo independent audits to ensure better security.
