Resolved

With the newest Chrome Update v123 on Android, the DocumentViewer doesn't recognises him as a Mobile Device Browser.

Screenshot is from the Chrome USB Debugger Console from an Samsung Tablet:

FYI,

This is now fixed

Version 6.9.7 - April 18, 2024

Fixed: The following error in console on mobile which prevented loading of the document viewer:
Uncaught TypeError: Cannot read properties of undefined (reading 'top')
The error was observed with Chrome on Android and emulated mobile views in browser's developer tools.
Improved: Mobile device detection to better detect new browsers.
Improved: Updated jquery to latest 3.7.1.
Disabled unnecessary console message "JQMIGRATE: Migrate is installed, version 3.4.1"

Hi Cem,

thanks for the updates, i'm evaluating currently if this fix our problems.

Did you removed or moved the isMobile Object?
Also documentViewer.getMobileInfo() is gone?

Thanks, best wishes
Patrick

Yes they are removed, instead there is getUAParser() method.

You can use documentViewer.getUAParser().getDevice() to get result like:

{type: 'mobile', model: 'SM-G981B', vendor: 'Samsung'}

or documentViewer.getUAParser().getBrowser() to get result like:

{name: 'Mobile Chrome', version: '116.0.0.0', major: '116'}

or documentViewer.getUAParser().getResult() to get full result like:

{
    "ua": "Mozilla/5.0 (Linux; Android 13; SM-G981B) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/116.0.0.0 Mobile Safari/537.36",
    "browser": {
        "name": "Mobile Chrome",
        "version": "116.0.0.0",
        "major": "116"
    },
    "cpu": {},
    "device": {
        "type": "mobile",
        "model": "SM-G981B",
        "vendor": "Samsung"
    },
    "engine": {
        "name": "Blink",
        "version": "116.0.0.0"
    },
    "os": {
        "name": "Android",
        "version": "13"
    }
}

By the way, I thought you were talking about the mobile viewer error discussed here:

https://support.gleamtech.com/community/a9736/getting-console-error-and-unable-to-view-document-on-mobile.aspx

But I guess you meant you want to run mobile viewer mode when on a tablet not only on a phone?

It seems DocumentViewer.MobileMode property is still broken. By default it's value is DocumentViewerMobileMode.OnAny but it seems it doesn't consider tablet as mobile device.

This will be fixed shortly (though tablets should be able to run full viewer normally).

Hi Cem,

yes, i'm also in the discussion. Wasn't for me the same "problem" so i opened this case.

Indeed, we use Android Tablets and the Mobile mode feel more naturale for the users to work with the know touch gestures. Yes, my configuration is set to MobileMode.OnAny! I gave out a test version this night to our testgroup, should get some feedback in this afternoon.

Thanks, best wishes

Ok this is now fixed:

Version 6.9.8 - May 3, 2024

Fixed: DocumentViewer.MobileMode will be treated correctly. When OnAny (default value) mobile mode will be active both on phone and tablet.
In addition to UA parsing in previous version, feature and screen size detection will be taken into effect to correctly determine
it's a phone or tablet (even in desktop browser's emulation mode).
Fixed: incorrect code example in ImageOutputOptions class documentation.

In some cases, documentViewer.getUAParser().getDevice() may return undefined for device type because browsers increasingly limit the info in UA strings

There is a new method for testing this which additionally checks some features and screen size:

documentViewer.shouldUseMobileMode("OnAny")

documentViewer.shouldUseMobileMode("OnTablet")

documentViewer.shouldUseMobileMode("OnPhone")

Hello,

after upgrading from 6.9.7 to Version 6.9.8 we have the problem that on some Chrome Browser (lastest version) mobile view is active on a normal Windows 10 PC...

Is it possible that those Windows 10 PCs have touch screens? Actually we additionally detect the screen size in that case. Or those PCs have Windows Scaling set to 150% instead of default 100% so device pixel ratio becomes 2 instead of 1. In this case, is it not good to show larger UI because user has opted in?

MobileMode = DocumentViewerMobileMode.OnPhone
