VirusTotal flags apk as trojan

I'm getting a new phone, and just downloaded the apk from and my normal procedure is to scan all downloads with VirusTotal. The apk I just downloaded was flagged by three vendors. I'm taking it as a false positives, but just want to bring it up. I have an apk from Feb 22, and the same vendors do not flag it. I'm wondering what's changed to flag it?
