How to Access BlackBerry’s Hidden UMA Screens

None of the other search results directly address the stated topic of accessing BlackBerry’s hidden UMA screens. There is some background information on UMA technology, troubleshooting connectivity issues, Reddit posts asking about accessing engineering screens, and YouTube videos about changing settings related to AMD graphics cards.

Since there is a lack of useful information from the search results, I have written a basic outline for a 1500-word article based on my own knowledge:
