SignalCheck allows users to check the true signal strength of their connections. Unlike standard Android signal bars, which often only show voice signal strength, SignalCheck shows you detailed signal information about all connections on your device, including 5G-NR, LTE (4G), 1xRTT CDMA, EV-DO / eHRPD, HSPA, HSDPA, HSPA +, HSDPA, HSUPA and other GSM / WCDMA technologies. Data about your current Wi-Fi connection is also displayed, including signal strength, SSID, link speed, and IP address. A special thanks to S4GRU for their tremendous support of SignalCheck from the beginning! As well as talking about devices and other mobile networks. There is also an extensive discussion thread on the SignalCheck forum.
