Hi. The mode section is obsolete in the latest version of PS Touch. The mode section in previous versions was the trigger point to switch between Effects-and normal painting.
We added a separate Effects Paint Tool to cover this. You can find this tool beside the normal Paint tool.
Hope that answers your question.
Thanks for answer.But can you add more brush with new/next update ?I mean that not only round brush,like Photoshop's desktop versions. Because round brush isn't useful for painting.
