I was under the impression Android performance was generally working fine for most people, as my own tests look fine and I hadn't seen any complaints about it for a long time. The problem in this thread appears to be enabling worker mode, which runs in to a known issue. Turning it off (which is the default) should mean problem solved.
If not, please file an issue following all the guidelines! I'm not telepathic so I can't solve problems by reading descriptions or watching videos, we need the details requested by the bug report guidelines to investigate, and I don't believe any Android performance issues have been submitted that way lately, so as it stands we have nothing to investigate.
Think we should have more staff to work on Construct? Then we need to grow the business, and a new product is potentially a great way to do that. If it went well it could double the size of the business - perhaps even more if it's a hit - and we could hire more developers as a result. Alternatively we can do nothing and remain a smaller company with limited resources. So if you want us to grow, it makes sense to be in favor of new ventures like Construct Animate.
