When I tested my game on an older device (Galaxy S2), it crashed without message. Debugging showed a segmentation fault similar to the one on this post: Crash on older Android devices
I’ve tracked the error back to the Tilemap, which I was using for particle effects. When I disabled it, the error stayed away. In the above post, there was a link to an experimental fix (in Shader.hx), that so far seems to work well for me: https://github.com/openfl/openfl/commit/8b9e389be12ae7b69699847a43dee2822422936a
Now I wonder if that fix could affect behaviour on other devices?
The reason I ask is because that fix is not part of the official OpenFL branch.
OpenFL 7.1 was released yesterday, and includes fixes to older Adreno GPUs (tested on a Galaxy S4) as well for the Tegra GPUs.
Go ahead and download the latest versions of Lime and OpenFL, and see if that fixes it for you
