I'm currently doing an xpub to be used on Samsung Galaxy Tab 4 android tablets. I appreciate these are old tablets (2014) but I'm seeing the same issue on a Huwaei P Smart, a phone which was released over the past 12 months. By contrast, all iOS devices (iPhone 6s, 10.5 iPP and one other iPad whose spec I don't know) work very nicely.
The problem is one I've seen mentioned in these forums before, which seems exclusive to Android. It's the measurable delay as each and every page loads, together with a spinning wheel. I can understand that the specs of the SG4 could explain the lag when dragging items (this is NOT present in the Huwaei, so I'm assuming it's a side effect of the poor specs), but the delay in page loading and the spinning wheel appears regardless. As I said above, neither of these issues present on the iOS devices, even the comparatively old iPhone 6s, which was itself released in 2015.
Is there anything I can do to reduce this lag?
I've tried:
-adding a 'fade' screen as a top layer on pages that's set to fade. Yes, this helps with the lag, but annoying wheel still shows and makes the thing feel even slower than it is!
-compressing pngs. That might have been marginally faster, but it resulted in white screens flashing during the load time, so I disabled it again.
-reducing object transparency (no difference).
Any thoughts? This project is intended for families to use at a local museum, and whilst I know some of the lag is spec related, I worry it could put prospective users off and give them a negative perception of the whole experience. Is there ANY way to eliminate the circles altogether on Android devices?
Hoping for a swift reply,
Lisa.
