Technical Analysis & Behavior
Package Analysis for 'com.samsung.rcs' (Oem / Recommended Debloat Target): RCS (Rich Communication Services) Has permissions linked to com.samsung.cmh, and com.samsung.android.visionintelligence (and I don't understand why). RCS is a communication protocol between mobile telephone carriers and between phone and carrier, aiming at replacing SMS. Uses IP protocol, so it needs an internet connection. It's a hot mess right now. It aims at being universal but only exists in Samsung Messages and Google Messages, because Google hasn't released a public API yet, so 3rd-party apps can't support it. In a lot of countries messages go through Google's Jibe servers. Android users frequently spot 'com.samsung.rcs' running persistently in Battery Usage, Network Data Monitor, or Developer Running Services. Note: Malicious trojans and stalkerware APKs also frequently spoof legitimate Oem system package names like 'com.samsung.rcs' to evade manual detection.
