Hello @Uragonda, Rajesh ,​

Welcome to our Microsoft Q&A platform!

Using IconOverride we are unable to change the icon of the back button

Is the icon not changed? Or it's displayed as a white square background? For the first case, the icon file may not be placed in the resource folder of each platform. Please make sure that image files are added to each platform project. For more details about this, you can refer to this document.

In the second case, the problem lies in the image file itself. The background of the icon file needs to be transparent. You can download the 'back.png' icon of the official sample for test to check the problem.
