Seems to be Oneplus' Memory Management System according to a press-kit/-release they made for Android 11 (multiple sites wrote "ORM Memory Management System" word-for-word). Runs in the background as part of the system. Runs even if disabled? Doesn't use any RAM when disabled tho, vs ~50MB when enabled. Seems safe to disable, haven't noticed any negative effects in weeks of use, but I assume it breaks the "RAM Boost" feature (which is pointless anyway IMO). Apk file name: OPOmm, mm = Memory Management? Has 2 permissions: KILL_BACKGROUND_PROCESSES and SET_TIME_ZONE. Contains 2 services: OPManagerService and BackgroundCollectorService.
