Yatca is built using the OS 4.6 development tools. As such, it doesn’t have any Storm awareness and depends entirely on the automatic compatibility mode that Storm devices enter when running pre-4.7 applications. If you’re seeing UI problems such as unresponsiveness to the accelerometer, poor layout with ridiculously large buttons, or strange focus behaviour, the most likely explanation is an…issue…with the compatibility mode.
I would love to be able to offer a Storm-specific build of Yatca with support for gestures and greater cognisance of things like button sizes but I simply don’t have the resources at this time. I need to target the largest possible number of users (subject to the 4.6 restriction that is intrinsic to Yatca) and the reality is that the majority of 4.6+ devices out there are not Storms. With the release of fantastic new full keyboard models like the Curve 8900 this is unlikely to change any time soon.
Edit: User catstide has reported that he/she has a much better Yatca experince on the Storm when compatibility mode is disabled. So this might be worth a try. You’ll find details in this article.
