PDF schematic covering the WiFi, Bluetooth and GPS section for SM-A23, which appears to be a Samsung Galaxy A23 phone model number. The document helps a technician trace antenna paths, power supplies and control lines of the wireless module when there is no WiFi, Bluetooth pairing failure or poor GPS lock. It opens in any PDF reader. Because phone variants share model prefixes with different hardware, confirm the exact model and board revision before relying on component locations or values.
