Thanks, I agree with the linked issue that this indicates a 64-bit CPU operating in 32-bit mode. I've previously seen this in watches (chaquo/chaquopy#709 (comment)), but I guess it may also be used in other ultra-low-power devices. See this StackOverflow discussion.

Treating this as armeabi_v7a looks like a correct fix (Mrakorez/pydroid@b9d57f0), but we should check whether anything else needs to be updated at the same time.
