Smartphone battery drains fast, doesn't charge, loses signal, camera glitches, or screen flickers — most issues aren't immediately obvious. Phone diagnostics pinpoint whether the problem is hardware-related (battery, motherboard, flex cables, display, buttons, speakers, microphone, cameras) or software-based (system errors, malware, failed update, corrupted files).
