Very long wrong Order ID

[desmeit]

Usually I get the correct Order ID from Android:

GPA....

But sometimes I get a Number like this:

7689645030334845685.4253362990032550

But I cannot find such a number in my order history and in addition if I try to get infos through the purchachsetoken there is nothing. but the order and the callback was successful.

is this issue related to certain user devices?

That is due to the user using a rooted phone and has altered your app to get free in app purchases. you should do some receipt validation before paying out the in game items that was purchased.

Thanks a lot. Now I check the receipt before. ;-)
