Subject [jira] [Created] (CB-12910) Cordova Android uses wrong screen density
Date Mon, 12 Jun 2017 08:38:00 GMT
Gaspy created CB-12910:
--------------------------

             Summary: Cordova Android uses wrong screen density
                 Key: CB-12910
                 URL: https://issues.apache.org/jira/browse/CB-12910
             Project: Apache Cordova
          Issue Type: Bug
          Components: cordova-android
         Environment: Samsung Galaxy Tab S and Galaxy Tab S2, Android 6.0.1
            Reporter: Gaspy
            Priority: Minor


In some circumstances, the Cordova webview uses wrong screen density, resulting in blurrier
text and images.

With the default blank Cordova app (cordova create MyApp; cordova add platform android; cordova
run android), at least on two tablets - Samsung Galaxy Tab S 8.4" and Samsung Galaxy Tab S2
8" on Android 6.0.1, if one runs window.devicePixelRatio, the result is 1.5 instead of 2.
Querying the same from Chrome or Samsung browser yields the correct result, 2.

I tested the same app on a Samsung Galaxy A3 2017 phone, also running Android 6.0.1 and the
result was correct, so the issue does not affect all devices.

I tested with a more complex app and the difference between Cordova and browser is noticeable.


Of course, the default app uses the viewport metatag <meta name="viewport" content="user-scalable=no,
initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width"> and no plugins.
