Technical Analysis & Behavior
Package Analysis for 'com.sonyericsson.android.omacp' (Oem / Advanced Debloat Target): omacp = OMA Client Provisioning. It is a protocol specified by the Open Mobile Alliance (OMA). It is used by carrier to send "configuration SMS" which can setup network settings (such as APN). In my case, it was automatic and I never needed configuration messages. I'm pretty sure that in France this package is useless. Maybe it's useful if carriers change their APN... but you still can change it manually, it's not difficult. These special "configuration SMS" can be abused : Android users frequently spot 'com.sonyericsson.android.omacp' 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.sonyericsson.android.omacp' to evade manual detection.
