Is the button issue resolved now?

After receiving a 945 a couple of months ago and seeing reports here of buttons not clicking that the up and down buttons on mine were quite squishy.

i didn't see much point exchanging at the time as replacements looked to be the same or worse.

Wondering at this stage if the issue has been fixed 100% or is it still current on new ones as otherwise this one is working ok.

For me the down button clicks if left a couple of seconds between pushes while the up button never clicks.

i'd like to know I'm getting one that's better before swapping otherwise it's not worth the inconvenience. 

I'm in Australia if that makes any difference to the batches being sent out.
