Unfortunately, the sound issue did not go away, the lags are still there. I made a tentative fix to Survivalcraft 2 full version a few days ago, and submitted it to the store as a test. It gradually started to become a problem recently, as Android devices matured, and the framerate was more likely to stay at 60fps+ all the time. But, as framerate in these ancient times was jittery anyway, the drops weren’t very noticeable. The slow audio playback causing framerate drops on Android has always been there, since 1.17 release back in 2012, the first version available on Android. External keyboard & mouse control not working on mobile devices.“Adventure Restart” functionality not working properly with adventure worlds created in older versions of the game.Framerate drops due to sound effects playback on Android devices.

I have finished work on the new bugfix release in the 2.3 series.
