Performance video between Official Zoom App and Custom Zoom SDK Client

Description
one is official App and the other is custom the other is custom sdk client app.
With same Android Tab devices and same network and same host connetion, the performance of video is not equal. It seems that the custom sdk client app has slower speed and lower video quality than official app.

Which Android Client SDK version?
lastest version 5.5.1.1317

Hi @bnbcompany.ceo, thanks for using our SDK.

Sorry to hear you are experiencing differences in quality/performance between the SDK and the client. Can you please confirm whether you are using the default UI in the SDK or implementing a custom UI?

Thanks!

Sorry. Maybe it seems my fault for testing
