Wrong diagonal screen size calculated leading to wrong dpi

Closed this issue 7 years ago · 1 comments

I'm using a Lenovo A3300-HV tablet. It has a resolution of 1024x600 and a dpi of 169 (Verfied by a third-party app CPU-Z). It is a 7" tablet

Your site http://dpi.lv , on visiting from the tablet correctly displays the resolution but incorrectly calculated the diagonal screen size. It should have been 7" but the site displayed 13.3" leading to a wrong dpi (89, instead of 169).

FWIW, I used the latest version of Chrome for Android when visiting your site

Unfortunately, there's no way to tell how large the screen is physically from the browser, so it relies on the user inputting that value.
