If you mean version 0.2.1/0.2.2 on android. Then there is no helping that version have problem that most devices will not be able to run it, needs too much ram.
That is why it is old version and why new versions are called rebuild.

That I'm not sure but I was able to run it in emulator caped at 8GB but it is also 64 bit version. So probably there is more to this problem. But on few devices apparently that version was able to run.
But what LAGS found is that all assets used way more storage a memory space do to how they were made. That is why the rework.
