I am just starting to develop applications for Android, and I have a question. Is there a standard screen aspect ratio for Android mobile phones, for example, for TV screens or computers (4: 3, 16: 9)? Thanks
This is a common question. It is not standardized, but you should be able to easily find out the aspect ratio of any particular phone.
This is the previous question that will help you.
5: 3 is common right now, but the short answer is no . No specific relationship is standardized.
