Inquiry about UserAgent value changes based on display size settings

Hello,

We are using UserAgent values to distinguish between tablets and smartphones. However, when setting the display to maximum size in Settings - Display - Screen zoom menu, the word ‘Mobile’ appears in the UserAgent value as shown below:

Mozilla/5.0 (Linux; Android 14; SM-X205N Build/UP1A.231005.007; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/129.0.6668.81 Mobile Safari/537.36

Not only the UserAgent, but also the Configuration.SCREENLAYOUT_SIZE_MASK value in Android code does not return as:

SCREENLAYOUT_SIZE_LARGE, SCREENLAYOUT_SIZE_XLARGE

This issue occurs on devices such as the Galaxy Tab A8 and Galaxy Tab S9+.

Could you please confirm if this is a bug?
