App Enhancement Services
If enabled, connects to OPPO servers (icosa-service-eu.allawnos.com) every time a new app is installed. Seems to be mostly focused on gaming performance optimisation according to the settings description:
‘[…] a service that optimises phone performance for specific apps and game scenarios. […] frame rates, battery usage, touch sensitivity, network connection, vibration and gameplay assistance features.’
Can be disabled via hidden setting (Settings -> Search ‘App Enhancement Services’ -> App Enhancement Services).
