After reading all this guff i just went for the 1.0 symos version - the changelog seems to be of less than zilch importance anyway. Game plays perfectly through to level 19 - wow - best graphics i've ever seen on my tab - faultless. Enjoyed the Monument Valley game i got the following day (well, the 1 hour to complete it), but found myself sneering at the graphics of that one when you see the bar being so raised by Leo.
****edit***
The symos 1.0 verison worked right through to completion - completing 19 brings up a hidden final level and you complete that and get the end credits - all worked perfectly without a single pop-up or crash (didn't try and connect via googleplay/+/facebook or any of that shite btw - just played the game offline). So that's maybe the version to try if you're running into difficulties. Just bunged the obb content into android/obb folder, blocked the game's connection with my firewall (no idea if that made a difference - just something i do by default with any offline app) and bingo.
