Hahaha After I installed AZ screen recorder, recorded a couple of videos and closed it, the game returned to its normal speed. For the first time ever on my tablet. Although truth is, my tablet (finally) had a software update that improved the compatibility with popular apps... So now which one is it. Well, not that it matters, all my data in tablet was lost due to uninstalling and reinstalling.. .
Alright, the problem is solved! When I launched the game on my tablet after a while, I sadly found out that I had been returned back to the crappy slow speed I have experienced earlier. So I tried the same thing. I launched the AZ recorder and recorded a short part of myself playing the game. After I stopped the video, the game became faster. So I recorded another video... Only to find out that the game speed increased again! It takes me three or four videos to get a plus minus normal game speed. However, turning the device off returns me back to the slow speed. contributor, maybe it will help you too.
