Introduction
AI Assistants and AI Features: AI assistants like Google Gemini, Apple’s Siri, and Samsung’s Bixby have become indispensable on modern smartphones, handling everything from voice commands and photo editing to predictive text and real-time translations. In 2025, with over 80% of Android and iOS users engaging AI features daily, these tools enhance productivity and convenience, processing billions of interactions worldwide. However, beneath the seamless experience lies a complex web of privacy and security risks: from unintended data sharing to sophisticated attacks exploiting AI’s data-hungry nature.
In India, where 700 million smartphone users navigate under the Digital Personal Data Protection (DPDP) Act, concerns amplify—studies show 52% of users worry about personal data exposure through AI apps. This article breaks down the safety landscape, examining threats, real-world incidents, best practices, and regulatory safeguards to empower you with informed choices for secure usage without sacrificing functionality.
What Are AI Assistants and Features on Mobile Devices?
AI assistants are software integrated into smartphones, leveraging machine learning to interpret user inputs—voice, text, or gestures—and deliver contextual responses. On-device processing handles simple tasks like calendar reminders or camera enhancements via neural processing units (NPUs) in chips like Snapdragon 8 Gen 3 or Apple’s A18 Bionic. Cloud-based features, such as Gemini’s generative queries or Siri’s web searches, send data to servers for complex computations, raising the first red flag: off-device transmission.
In 2025, AI features extend to on-screen summaries (Samsung’s Now Brief), predictive emojis (Google Keyboard), and even health insights from wearables. While on-device AI minimizes latency and enhances privacy by keeping data local—processing up to 90% without uploads—it still accesses sensors like microphones and cameras. For Indian users, apps like Google Assistant dominate with 60% market share, but integration with local services (UPI, Aadhaar-linked queries) heightens data sensitivity. Understanding this split—edge vs. cloud— is key to assessing risks, as hybrid models balance speed with potential exposure.

Common Privacy Risks Associated with AI on Mobiles
Privacy breaches stem from AI’s insatiable data appetite: assistants collect voice patterns, location histories, and app usage to personalize responses, often storing them indefinitely. A primary concern is eavesdropping—always-on microphones in “Hey Siri” or “OK Google” modes capture ambient audio, potentially including sensitive conversations. In 2025, 55% of users report unease over this, per Canalys surveys, as snippets are transcribed and stored on servers for model training.
Data aggregation amplifies risks: AI features cross-reference info across apps, inferring details like health from fitness data or shopping habits from searches—leading to “shadow profiles” vulnerable to breaches. Indian users face added layers with DPDP compliance, where apps must obtain consent, but vague policies (e.g., “for service improvement”) obscure sharing with third parties. Inference attacks allow hackers to deduce private info from seemingly innocuous queries, such as “remind me about my doctor’s appointment,” revealing medical history. On-device processing mitigates some issues, but Android’s open ecosystem exposes more to sideloaded apps embedding malicious AI, unlike iOS’s walled garden.
Security Threats: From Hacking to AI-Specific Vulnerabilities
Security flaws in AI features turn smartphones into gateways for advanced attacks. Prompt injection, a top OWASP risk, tricks assistants into bypassing safeguards—malicious inputs like “ignore previous instructions” could extract contacts or install malware. In 2025, adversarial AI attacks rose 40%, per NowSecure, where altered images fool facial recognition, unlocking devices or granting app access.
Supply chain threats loom large: third-party AI models in apps like photo editors harvest data insecurely, as seen in Wondershare’s 2024 breach exposing 100,000+ user files via hardcoded cloud tokens. Voice deepfakes manipulate assistants—synthetic audio commands unauthorized transactions, a vector up 25% in India via phishing. Ransomware targets AI storage, encrypting models and demanding crypto ransoms, while memory injection alters on-device AI logic mid-runtime.
For Indian contexts, Android’s 95% market dominance amplifies risks—malware like AI-powered variants evades antivirus 30% better. iOS fares better with sandboxing, but jailbreaks expose Siri to exploits. Emerging threats include AI hallucinations generating fake alerts, luring users to phishing sites. Overall, while patches mitigate 70% vulnerabilities, unupdated devices remain prime targets.
Real-World Examples of AI-Related Incidents on Mobiles
Incidents underscore the stakes: In 2022, Amazon’s Alexa recorded an Oregon couple’s private talk and emailed it to a contact, sparking a $25 million FTC fine for lax privacy controls—highlighting always-listening dangers persisting in 2025 successors. T-Mobile’s ninth breach exposed 37 million records via an AI API hack, including PINs, enabling identity theft for affected users.
Activision’s 2022 phishing used AI-generated SMS, compromising employee data; similar tactics in India saw 2024 UPI scams via fake Gemini alerts, defrauding ₹500 crore. An Oregon Alexa glitch sent 1,700 stranger’s audio files, revealing routines and habits. Wondershare RepairIt’s 2025 exposure of user photos via insecure tokens affected 100,000, including sensitive images processed on-device then uploaded.
In India, a 2025 Gemini study flagged unsafe outputs for children, generating inappropriate content 20% of the time, raising parental safeguards issues. These cases reveal patterns: poor encryption (70% breaches), over-permissive APIs, and inadequate auditing—lessons for users to demand transparency from providers.
Regulations and Standards Protecting Users in 2025
India’s DPDP Act 2023, with 2025 rules, mandates explicit consent for AI data processing, defining sensitive info (biometrics, health) and requiring privacy policies—fines up to ₹250 crore for violations. SPDI Rules under IT Act 2000 supplement, demanding notice before collection and opt-outs for sharing.
Globally, EU’s AI Act classifies assistants as high-risk, enforcing audits and transparency; U.S. states like California mirror with CCPA, fining non-compliant apps. In India, MeitY’s AI Mission 2024 sets ethical guidelines, banning discriminatory outputs and requiring watermarking for generated content. Apple and Google comply via on-device processing mandates, with iOS 18 limiting cloud uploads to 50% of features.
For users, regulations mean better recourse—report breaches to CERT-In within 6 hours, triggering investigations. However, enforcement lags: only 30% apps fully DPDP-compliant in 2025 audits. Stay updated via TRAI alerts for compliant apps, ensuring safer AI use.
Best Practices for Safe AI Usage on Your Device
Mitigate risks with proactive habits: Review privacy settings—disable always-listening (e.g., Siri’s “Hey Siri” toggle) and limit app permissions to essentials, revoking microphone access when idle. Use strong passcodes (alphanumeric with biometrics) and enable two-factor authentication (2FA) for AI-linked accounts like Google.
Opt for on-device features: Android’s Private Compute Core processes 80% AI locally; iOS’s Neural Engine does similar for Siri. Avoid sharing sensitive data—phrase queries vaguely (e.g., “remind about appointment” not “doctor visit details”). Install reputable security apps like Avast or Malwarebytes, scanning for AI malware weekly—update OS promptly, as patches fix 90% vulnerabilities.
In India, use UPI-safe modes and avoid AI for financial queries on public Wi-Fi. Educate on deepfakes: verify voice commands visually. For families, enable parental controls on Gemini to filter content. Regular audits—review app data exports quarterly—empower control, reducing breach risks 70%.
Future Outlook: Balancing Innovation and Safety
By 2030, AI on mobiles will evolve with quantum-secure encryption and federated learning—training models without central data sharing—cutting privacy leaks 50%. Regulations tighten: India’s AI Ethics Framework 2026 will mandate bias audits, while global standards like ISO 42001 certify safe assistants.
On-device AI surges to 95% processing via advanced NPUs, minimizing cloud risks, but edge computing invites new threats like model poisoning. Users benefit from AI-driven security—antivirus using ML to detect anomalies 40% faster. In India, DPDP expansions will enforce data localization, shielding from foreign breaches. The future demands vigilance: innovate securely, or risk eroding trust in AI’s mobile ubiquity.
