# POST /#X-Amz-Target=DeviceFarm_20150623.ListUniqueProblems

`POST /#X-Amz-Target=DeviceFarm_20150623.ListUniqueProblems`

Gets information about unique problems, such as exceptions or crashes.

Unique problems are defined as a single instance of an error across a run, job, or suite. For example, if a call in your application consistently raises an exception (`OutOfBoundsException in MyActivity.java:386`), `ListUniqueProblems` returns a single entry instead of many individual entries for that exception.
