Benchmark reveals that the Samsung Galaxy Note10 will have a 19:9 screen
The Samsung Galaxy Note10 screen will match the Galaxy S10 phones with a 19:9 aspect ratio (the Galaxy Note9 has an 18.5:9 screen). This is most likely due to the switch to punch hole selfie camera(s).
The new flagship will be available in two sizes Galaxy Note10 and Note10 Pro, both of which will come in 4G and 5G versions. One of these models, Verizons Note10 Pro 5G judging by the model number (SM-N976V), was spotted in the HTML5test database.
Based on the rumors, the vanilla Note10 will have a 6.28 screen and the Pro will go up to 6.75. Assuming a 1440p+ class display, the resolution will be 1,440 x 3,040px (note that the benchmark recorded the virtual resolution of the mobile web browser).
Using this resolution, we can calculate the pixel densities of the two screens 536ppi for the vanilla and 498ppi for the Pro. The benchmark also reveals that the phone runs Android 9 Pie, no surprises there.
