Adding this in a separate comment so it's easier to find.
While I need to do some quick testing to make sure everything is in working order, I have an old Samsung that I may be able to send you for testing the 32-bit build. However it's still a decently large maybe, mostly due to potential shipping costs and not knowing if it'll actually run or not.
For context of how old the Samsung is, you can take the back off and hot swap the battery.
Edit:
One additional note, the testing I've been doing is on a Motorola Edge+ (2022), which, as noted in the screenshots, has a tall screen compared to most phones.
