[Android][Chrome] Mobile Chrome is not recognize as mobile

Reported by: Piotr Jasiun Owned by: Szymon Kupś
Priority: Normal Milestone: CKEditor 4.5.4
Component: General Version:
Keywords: Android Cc:


Tested on CKEditor 4.3.4, Chrome 33 on Android 4.4.2.

CKEDITOR.env look like this:

air: false
chrome: true
cssClass: "cke_browser_webkit cke_hidpi"
gecko: false
hc: false
hidpi: true
iOS: false
ie: false
isCompatible: true
isCustomDomain: function () {
mac: false
mobile: false
needsBrFiller: true
needsNbspFiller: false
opera: false
quirks: false
secure: false
version: 537
webkit: true

So "mobile" is "false" and should be "true".

I did some research and found these articles:

Conclusion after doing some tests on devices and emulators:

  • Android phones include Mobile, Android and Chrome keywords in UA string.
  • Android tablets should not include Mobile keyword but include Android and Chrome keywords.
  • Android phones and tablets in "Request desktop site" mode report desktop UA string.

Proposed solution:

  • For Android phones we can stay with checking if mobile keyword is present.
  • For Android tablets we should check if Android and Chrome/[.0-9]* patterns are matched.

I think that we should not detect mobile devices and we should deprecate That doesn't make sense any more, because tablets are closer to desktops than phones. What's actually interesting for us is screen resolution. Nothing more.

I think that feature detection is a great concept, but it would not work in our case. On mobile devices we have a different interface: no drag&drop event, not right click, no hover, keyboard may appear. Because of these, some functionality may need additional features. Examples?

  • there is no context menu so maybe there should be an additional panel with the context options on mobile,
  • there is not hover, so maybe magicline or table resizer should be show more often?

I agree that such features could be designed that way they work on all touch devices, but it is too late to do it in the CKEditor 4, we need only a solutions for mobile without redesigning everything. I agree that mobile android tablet may have a keyboard and mouse and the desktop laptop may have a touchscreen. But the addition features for mobile accessibility will not be an issue even if the user has a keyboard and mouse and will be unnecessary on the desktop.

Talking about the solution I am not sure about the Android && Chrome check. Is not it enough to check if it is Android?

PJ, you're drifting. There should be a subset of interface which works on desktop and touch devices. That subset should be enough to use the editor. You don't need to know if something is touch device or not. You simply need to handle both kinds of events.

One more thing:
