Hello,

I currently have implemented the carousel with a custom item template which includes an image and a few buttons below, with the carousel vertical and horizontal settings set to "Fill". This seems to work great until I increase the number of items in the carousel beyond 20 on the Android platform. Once the itemsSource count is greater than 20, the transition effect between items (when swiped) will be a quick flicker rather than an animating transition. 

I have modified the sample by adding a few buttons below the image inside of the data template, setting the carousel vertical and horizontal to "Fill", and increasing the item source count to 20 items. This issue can be more visible when adding more items to the itemsSource if necessary.

Hi Trevor, 
 
Greetings from Syncfusion. 
 
We have checked with the sample attached and we have found the animation working little slow since the ItemTemplate has been added. We have attached the video with which we have checked the issue. Please have the video from the below link,

Please check and confirm whether you are facing the same issue in your application then only we can proceed further with this and able to provide an appropriate solution.

Yes, I am seeing the delay shown in the video or a "flicker" as the carousel item moves into place rather than the transition. Both scenarios seem to happen when the carousel items are greater than 20 with the custom item template on Android.

Hi Trevor,  
  
Thanks for your confirmation, currently we are checking the root cause for this problem. Due to the source complexity we need some more time to work on this. We will update you the details on or before June 13th, 2019. We appreciate your patience until then.

Hi Trevor,  
  
Due to the stability concern we have not moved the performance fix in our past releases. We will fix this issue and merge the fix in our upcoming volume 3 release, which will be available on end of September 2019.
