Snapshot disappears only when unlocking with fingerprint

I am invalidating and re-creating the snapshot each time the app is resumed.

It works when I switch between apps, when I lock and unlock the phone using a pattern or face recognition. Although if I lock my device while I’m on the app and unlock my phone using my fingerprint, the snapshot disappears.

Any idea what could be the reason?

Also, if I have locked and unlocked the phone with either face recognition or pattern, and then lock and unlock with fingerprint, it works sometimes! :confused:

Here’s the code:

local SnapshotObject = require(...');
local M = {};

function M.new(params)
  local instance = display.newGroup();
  local obj1;

  local function render()
    obj1 = SnapshotObject .new(params);
  end

  render();

  local onSystemEvent = function(event)
    if (event.type == 'applicationResume') then
      if (instance and instance.insert) then
        obj1:removeSelf();
        render();
        instance:insert(obj1);
      else
        instance = nil;
        Runtime:removeEventListener("system", onSystemEvent);

        return;
      end
    end
  end

  Runtime:addEventListener("system", onSystemEvent);
  instance:insert(obj1);

  return instance;
end

return M;
