This is what the phone says 
Discussion
Is that chrome? Can you try another browser? I have no idea what is the reason from that message
Were you able to use zapstore on that phone before or never?
No that’s the files app on this phone. I’ve tried though chrome and obtainium, neither worked.
No. It’s never been on this phone
Then your phone probably does not support the arm64-v8a architecture. Other archs will be supported soon
So other APKs install fine in this way?
