Device Emulation variable DPI

I really don’t know what’s going on with the device emulator, but it’s definitely not working how it should be. My S3’s resolution is 1280x720, but that’s as big as a normal (but old) screen. Upon adding a new device to the emulator, ROBLOX tells you the resolution that it uses is 96 DPI:

Apparently my Galaxy S3 has a DPI of 306. This would mean that to get the correct size I would have to do:

(96/306)*(resolutionX, resolutionY) to get the correct size. That yielded (402, 226) which is definitely not correct.

Here’s what it looks like on my phone:

I played around with the numbers, and ended up using (640, 360) which yielded what appears to be the exact same as what was displaying on my Galaxy S3:

Would that mean that the DPI is actually 153? I don’t know, but what I do know, is that something is seriously wrong with the device emulator. Would appreciate if it were fixed, and when that happens if we could also input our own DPI so we don’t have to do math conversions to figure out what the correct resolution is.
