Hi @Maxwell
I have a Honor 8 (Huawei Clone, Model numkber FRD-09) Smartphone with Android 7.0 (EMUI Version 5.0.3, Build Number FRD-L09C432B412).
I tried to use PowerApps (Version 3.18124.25) and PowerBI (Version 2.2.190109.112411). I'm not able to authenticate with my work account on both Apps (Different error messages).
SharePoint and OneDrive are working on the Smartphone.
I tried these Apps on my Samsung Tablet (Tab A6) with Android Verion 8.1.0 and Samsung experience version 9.5 as well.
On this device all apps (including Flow, Planner and Teams) are working without issues.
for instance, Power BI detects that I'm connected to the same tenat with another App and connects immediately.
I suppose that's a problem with the Smartphone OS.
I was not able to find a setting to fix this issue so far.
Thank you for your support.
Regards
Salvatore
