Does Unity prefer Webgl exported content to run on Tablet and ipad browsers???
No. If you’re targetting iPads or Android tablets then you should build for iOS or Android.
WebGL is currently suitable for desktop browsers only.
if you are good with optimization, you can make games who run on any device
where i am working, our game run on pc browsers and apple & android mobile devices browser of medium range (like a galaxy s3)
we still have some issues with ipads but everything else work fine.
(iphone had less issues and ipad for some reason)
