Pixel Density/Physical Screen size of Fairphone models

Can anyone please check the detected pixel density/physical screen size of the Fairphone models on Andoird? I’m mainly interested with Fairphone 4 and 5. Not sure how to check this on Android but I’m sure there’s an app for this?

I’m asking this because I’m using Ubuntu Touch and the Fairphone 5 is detected to have almost 10” of screen. While the Fairphone 4 is a lot more accurate but it’s still 1/8 inch higher than it should be when displaying a 1x1 inch square.

Based on the developer’s investigation, it seems like something on the Android side (Ubuntu Touch use Android parts for drivers and such). Now I wonder why it seems like Fairphone models always have inaccurate pixel density. I even saw this thread about the FP2 :sweat_smile:
I checked 2 other devices and they basically have exact measurements.

Thank you!

Where is it exactly? Is it in vendor.prop? I can’t find it there.
Also this seems to be LineageOS, it’s probably different from stock?

Just scroll…

FP4 :
Display 2340 x 1080 (19.5:9), 6.3 inch

FP5 :
Display 2770 x 1224 (20:9), 6.46 inch

How ?
LineageOS is a collaborative software editor, not a hardware clone manufcturer

Hi, I appreciate you answering. Thanks for that.
I’m asking about what the system detects and not what these phones are listed though.
So it has to be something from what the system is configured.

I found an app called Display Tester and under Tests > Display DPI measurement, you can measure if the grid is accurate to real life i.e. 1 inch
