How can you tell if someone is spying on your phone?
Detecting spyware or unauthorized access on your phone starts with noticing unusual behavior. Here are some signs that may indicate your device is being monitored, tracked, or tapped.
Increased data usage
If your monthly mobile data usage suddenly spikes without a clear reason, it could be a sign of spyware. Spy apps often use your cellular network to transmit collected data, leading to unexpected increases.
Unusual activity on linked accounts
Suspicious logins or activity on platforms like Google, social media, or iCloud may indicate a breach. For Apple users, flaws in iCloud security could allow access to linked accounts when using saved credentials. If you notice odd behavior, immediately change your passwords and review login activity to secure your accounts.

Weird pop-ups
Receiving unfamiliar push notifications or fake virus alerts could signal adware or phishing attempts. While cookie messages or ad blocker prompts are common, totally unknown pop-ups from untrusted sources are a red flag.
Slower phone performance
A noticeable slowdown in your phone’s performance, even on newer devices, might be caused by spy apps consuming processing power. While aging devices naturally slow down, persistent sluggishness warrants investigation.
Random reboots
Frequent, unexpected reboots without your input or a major error are concerning. These could indicate a hacker has gained remote access with admin rights, using reboots to execute malicious tasks. If your phone is not overheating, it’s probably a security breach.
Longer or impeded shutdowns
If your phone takes an unusually long time to shut down or refuses to turn off, spyware might be interfering. Malicious apps are often designed to prevent shutdowns to maintain access. If you notice this issue, search for suspicious apps that could be the culprit.
Blocked emails
Emails to friends or coworkers being flagged as spam or blocked by firewalls could mean malware is infecting your messages. Hackers may also gain access to your email account to send spam, causing legitimate emails to be flagged.
Random wake-ups
If your phone’s screen lights up without notifications or incoming calls, it might indicate background processes from spyware. While legitimate apps can cause this, consistent unexplained wake-ups suggest you should check for malicious software on your device.
Interference with other devices
Hearing static or buzzing from nearby electronics when not on a call could be a sign of spyware. These apps can cause interference when recording audio or transmitting data.
Strange noises during phone calls
Unexplained echoes, static, or distant voices during calls may indicate interception due to poor encryption or spyware. Modern phones use noise cancellation, so persistent audio glitches, even after restarting the call, could mean your security is compromised.
Weird texts
Receiving strange text messages with odd symbols or typos, or noticing sent messages you don’t recall, could point to spyware control messages. If this happens consistently, it’s likely a hacker has taken over your device.
Faster battery drainage
If your phone’s battery drains more quickly than usual without new apps or heavy usage, spyware might be to blame. These apps consume significant power to record or transmit data.
Warm battery when not in use
Your phone should cool down when not in use. While occasional overheating can occur, regular heat during idle periods suggests spyware or stalkerware running in the background, straining your device’s resources.
Autonomous app storage permissions (Android)
On Android devices, if apps are granted storage permissions or installed outside the official store without your consent, spyware could be present. Check Settings > Storage Permissions for unfamiliar apps with data access and remove them if suspicious.

Bad screenshot quality
Spyware like keyloggers can interfere with basic functions, including screenshot quality. If lag or performance issues affect screenshots, it might indicate something is wrong.
Malfunctioning autocorrect
If autocorrect starts behaving oddly or delays persistently, a keylogger might be tracking your typing. Spyware often targets keyboards, so any unusual typing behavior should prompt a security check.

Keeping your phone spyware free is paramount in protecting your personal and professional life. By recognizing signs of spying, such as data spikes, unusual account activity, and performance issues, you can act quickly to safeguard your privacy.
