We have created a trojan for phone with similar name sally for all the phone OS and set it to max 15.
Now we saw the trojan in the log file said the trojan max infection reached when we install to our target. However when this limit reach, it remove all of our target which is  5-10 with its trojan name sally of different OS.
It said in the Evidence Protection target remove injection. 

Why does this happen it should only remove the last target not all of them. Moreover its 15 plus other os so thats 30 for android and symbian not 15 both.

This is 4.1 since 4.2 trojan is totally unreliable and does not work on all of the phone.
