I've been having an issue where item frames with and without items and torches around these item frames popping off walls. I've already lost 24 item frames due to them being on the ground and despawn if I'm in the area.

I'm not entirely sure what's causing this issue. It could be changing dimensions, unloading and loading chunks or some conflict with torches.

Item frames with maps don't seem to be affected as my map wall has stayed intact.

This is happening on my iPhone 7 Plus. There's still no option available for my device.
