My wife and I have used Ken Magic's plain vanilla ad free Solitaire prog for a long time but my wife's Samsung J5 6.0.1 recent update has altered the menu long-hold 'key'. This has switched from the task display position to the back 'key' position. 

 

My 6.0.1 S5 didn't do this so it is a bit puzzling and I have no idea why mine is OK and hers isn't. And also no idea whether there is some method of diverting the long-hold back again.

 

Solitairecg is an alternative but still wonder why the S5 and J5 would be different in this respect.

 

(Yes, I know this is a first world problem!!).
