Question Answer
Is anyone who wants to develop themes allowed to create one? Only those who have been selected through an internal review are allowed to develop and register themes.
How do I apply to become a Theme Developer? Theme Developer applications open on the third Wednesday of every even month and remain open for two weeks. You can submit your application in this page.
What can I submit as my portfolio? You can attach a mock-up file containing a home screen, lock screen, and icon in .jpg, .pdf, or .zip format, or provide a URL. You may also submit any portfolios and designs that you have previously made for mobile devices such as skins, themes, illustrations, photos, and icons. [Reference template]
Make sure that you attach files saved in image format (e.g., .png, .jpg), .pdf format, or .zip format. If you add a cloud URL, such as Dropbox or Google Drive, we may be unable to review your portfolio.
What does the review process involve and how long does it take? We review portfolios based on the following criteria: creativity, originality, and theme development ability. The result will be sent to the email address you used to submit your application. It may take up to a month for us to notify you of the review result.
Is it possible to be excluded from a review? Your application may be excluded from a review in the following cases: if you wish to develop a theme for personal use; if you do not submit a portfolio; if you submit an image not created by you; or if you submit the same portfolio multiple times.
Why was my theme rejected during review? To develop and register Galaxy Themes, you must submit a Theme portfolio and apply to be selected through an internal review. Theme Developer applications open on the third Wednesday of every odd-numbered month and remain open for two weeks. 
Once your application is reviewed, you may not qualify for access to the Theme Editor tool for one of the following reasons:
  • You want to develop a theme for personal use.
