SignalCheck allows users to verify the true signal strength and details about their connections. Android standard signal bars and connection indicators are often inaccurate; SignalCheck shows you true and detailed signal information about all your device's connections, including 5G-NR, LTE (4G), 1xRTT CDMA, EV-DO / eHRPD, HSPA, HSDPA, HSPA +, HSDPA, HSUPA and other GSM technologies / WCDMA. Data about your current Wi-Fi connection is also displayed, including signal strength, SSID, link speed, and IP address. SignalCheck will display all available information that the device is reporting, including details about the NR and LTE connections. SignalCheck was one of the first (if not the first) Android apps to bring detailed LTE information to users.
