The TxPwrAdmin app is a hidden system-level application on Samsung Galaxy devices. Part of Samsungโs internal software framework. It appears under Device Admin Apps in settings because it manages certain background permissions and power-related functions. It is safe, pre-installed, and not malware โ though Samsung hasnโt published detailed documentation about it.
If I had to hazard a GUESS, I'd suspect it has something to do with controlling radio power output for either the cellular or WiFi modem, "Tx" being a common abbreviation for "transmit" or "transmission" in networking circles. (In contrast with "Rx", for "receive" / "reception".)
