PhoneCheck Pro vs Nurunuru Checker

evice Monitor is a fast, no-nonsense hardware inspection tool for iPhone. Whether you're buying or selling a used iPhone, or just want to verify that everything works on your current device, Device Monitor walks you through 8 essential checks in about 3 minutes. WHAT IT CHECKS • Screen Colors — Full-screen color patterns to reveal dead pixels, tint, burn-in, and bright spots • Touch — Interactive grid to confirm the display responds evenly, including edges and corners • Camera — Front and rear camera availability and live preview check • Flashlight — Hardware torch toggle test • Microphone — Short audio recording with instant playback • Speaker — Audio playback test using the built-in speaker • Biometrics — Face ID or Touch ID hardware support check • Connectivity — Wi-Fi, Bluetooth, battery level, charging status, and vibration HOW IT WORKS Each step gives a clear one-line instruction and three result buttons: Pass, Issue, or Skip. Automated steps run on their own — you just confirm the result. After all 8 steps, you get a clean summary showing exactly what passed and what needs attention. HONEST ABOUT WHAT IT CANNOT DO Device Monitor does not claim to verify original parts, Apple's official battery health, board-level faults, or IMEI/carrier lock status. It focuses on the hardware checks an ordinary user can meaningfully confirm in a trade situation. NO ACCOUNT REQUIRED Everything runs locally on your device. No sign-in, no cloud sync, no data collection.
