Full description

Is your phone really healthy? Device Doctor runs real hardware tests, tracks your battery honestly and gives you a clear health report you can share. Everything runs on your device. ★ REAL HARDWARE TESTS, NOT GUESSES Guided tests for the display (dead pixels and colours), touch and multitouch, buttons, microphone, earpiece, speaker, vibration, flashlight, front and back cameras, proximity and light sensors, and the charging port. A test only passes when the hardware responds or you confirm it worked. Hardware that wasn't exercised shows as "Detected", never as a fake pass. ★ USED PHONE CHECK Buying or selling a second-hand phone? Run the full check in a few minutes, get a grade and export a health certificate (PDF) to share with the buyer or seller. Spec consistency checks help you spot a phone whose reported specs don't add up. ★ BATTERY HEALTH YOU CAN TRUST - Live charging current (mA), watts, voltage and temperature, corrected for your phone's reporting quirks - Charging history and an estimated battery capacity that gets more accurate with every charge - Charge cycle count on supported phones (Android 14+) - Time to full and time remaining - Charge limit alert (for example 80%), full-charge and high-temperature alerts ★ COMPLETE DEVICE INFO CPU cores and live frequencies, RAM usage, storage, network, sensors with live graphs, camera specs, Android version and installed apps with their permissions. ★ HEALTH SCORE AND TIPS One clear score from battery, temperature, memory and storage, with plain-language tips based on real readings. ★ WIDGETS AND SHORTCUTS Home-screen widgets for battery, RAM and health score. Long-press the app icon to jump straight to a checkup or the battery screen. ★ PRIVATE AND LIGHTWEIGHT - Works offline: no account, no sign-in - Test results and history stay on your phone - Reports never include IMEI, serial number, accounts or your app list - Camera and microphone are used only during tests you start; nothing is kept or uploaded - Small banner ads only: never during tests, no full-screen ads ★ MADE FOR EVERYONE Light and dark themes, tablet layout, TalkBack support. Available in English, Hindi, Indonesian, Spanish and Portuguese. Download Device Doctor and run your first checkup today.
