What is epdgtestapp for a s8 phone

[Android Central Question]

Do I turn it on in the application setting

Welcome to Android Central! It's a system app: https://github.com/yos-one/mt8735-vendor/tree/master/mediatek/proprietary/packages/apps/EpdgTestApp. EPDG stands for Evolved Packet Data Gateway: https://insight.nokia.com/epdg-expanding-your-mobile-services-footprint

In short, leave it alone, and don't worry about it.
