This was my second attempt to get a DA29-0003G filter for a Samsung model PS277 refrigerator to work as an earlier version ordered from Amazon without having to modify it.  Thanks to those that determined a fix in the field.  These filters will not slide up to let the turn process start to let the filter lock without trimming the left hand sides of first polygon about 1/16 of an inch. I didn't want to remove the whole segment as many other reviewers did since appeared to set the stop point.  The other difference is the diameter of the top hole, but that did not appear to make a difference in fitting since the connector in the fridge is sealed by the set of two o-rings.  I agree with many others that Samsung should address this issue.
