I am looking into this and I think I may have found a solution, but I am not for certain since I do not have a newer Android device to test on. However, I will try to add a graphics toggle option that will hopefully address the issue in the next release. I believe it may have something to do with new Android devices not properly rendering all the SVG components correctly, specifically certain filter block data (that the mannequin specifically uses for the glowing edges).
If you are able to test play the browser version (it doesn't have to be the Backers version), do let me know if it's still an issue on there. I think it's definitely a device issue in that specific blocks of the SVG are being ignored or interpreted incorrectly in the native environment (Android in this case).
For the next version, with the new graphics option, try toggling the vector image effect to off and see if it makes a difference. That should remove the glowing edges effect on the mannequin (and any other SVGs that use similar filter data). I hope this helps.
