Issues Identified

• Profile Image is not labelled. Add contentDescription as : Current profile picture (Assigned to @yashraj-iitr)
• Edit Image is not labelled. Add contentDescription as : Edit profile picture (Assigned to @yashraj-iitr)
• *Required texts output is “Asterisk Required” which I think does not make sense. Add contentDescription as : Fields marked with an * are required. (Assigned to @yashraj-iitr)
• Need label for Info icon. Add contentDescription as : “More information on 3-digit PINs”. (Assigned to @yashraj-iitr)
• Allow Download Access Merge talkback content Currently talkback reads step by steps for this section: “Allow Download Access”, “User is … PIN.”, “not checked, OFF, Switch”. This also adds two extra steps for the learner. Instead it can be reduced to single output as per below screenshot.

Note: To understand the above issue(s) completely, it is recommended that you setup Talkback and play with the app keeping it on and that will give you better context.
