What's changed in the latest version of Sky Demon for Android? I have SD loaded on a few of my Android tablets. The one I normally use in the aeroplane is a 2012 Nexus 7. I also have a 2013 Nexus 7 which I've now tasked for use in the aeroplane. The 2013 Nexus is set to auto update, and has updated Sky Demon to 3.7.1.28802.  Even on the faster Nexus, scrolling around the map or zooming in and out is now painfully slow and often locks up with the message "Sky Demon is not responding" or such. This also happens in the air, and it also seems to lock up for some seconds when you change direction. Luckily my 2012 Nexus is set to manual update and I haven't updated the app. I am on 3.7.0.27593. This works fine and the scrolling and zooming are ok.

A‌ friend who has as Asus 173 (same architecture as the 2012 Nexus 7) has auto update, it's updated and is barely useable on that.

S‌o what did you do from 3.7.0 to 3.7.1 and can it be undone?

I'm suffering from this Android slowness as well. All my devices were Androids even before I bought SkyDemon.‌‌ New users aren't aware of this differences and will be disappointed by the performance (especially plates).

‌Tim, if solving this issues is not on your roadmap... please abandon Android or make it beta until you'd like to fix it. You should add this slowness to the known issues and warn potential users that the Android version is not as good as the iOS one.

‌Please‌‌ don't blame the OS. There are plenty of complex apps for Android that perform very well. It's the Xamarin framework that causes the performance issues and yes: it is expensive in terms of optimisation.

‌‌I know what I'm talking about, I'm a software engineer and did multiple complex apps for Android and iOS (native and Xamarin).
