Firstly I’d like to say you guys have raised the bar again with this latest beta. You have done a fabulous job with this framework.
On thing I did notice, whilst using the nightly builds of the latest beta over the last few weeks, was the inclusion of Platform Specific Transitions as noted in the release notes for beta.14. This improved the performance of transitions on android devices for my apps
Unfortunately it seems that this feature was removed just before beta.14 was released. I’ve created a codepen to illustrate the problem. Note that the problem is also present in the current nightly
After a brief dive into the code it looks like some code was backed out of the js/angular/service/ionicConfig.js file, which has resulted in android being treated the same as ios for page transitions. Perhaps there was a good reason for this however it does seem at odds with the documentation
