I can trust this guy? And how can you check the the Current battery consumption?

I just received a similar email from them. Did you correspond with them after the initial email?

This seems legit to me. I’ve worked directly with Samsung on app certification in the past and they used similar language.

Doesn’t seem to be legit :slight_smile:
