Size or Resolution of a photo image

Hi Community,
Is there any restriction on the size or resolution of a photo image used in AI2 ?
I found that if i use a image with size of a mobile phone such as 900x1600 and with size 114 KB, the photo image becomes very blurry.
How can i fix it?
Thank You!

How are you displaying the image? Screen background ? This is a long standing known issue.


Hi there, thanks for your reply.
No matter i used as background image, used in Canvas or in "Image", the photo image becomes blurry even i packed as apk and showed in mobile phone.

See here for background (excuse the pun) reading
