If I don't understand how to use a app or certain feature of an app(because UI of some apps are not intuitive enough to understand), can I ask that here?If not which stackexchange site is appropriate for asking this?
If you are having a problem in performing a task with an app, you can seek help on our main site. It is within the scope of our main site.
Per What topics can I ask about here? in Help Center:
If your question generally covers...
- Using your Android device
- Using a particular app on your Android device
- Trying to solve an error or other issue in using your Android device
then this is the right place to ask. Basically, what problem (with your Android device) are you trying to solve?
