What Am I doing wrong Droid 48

[Cdcerb]

OK,

So I write an equation, root it and solve. Equation is in the EQ line on the solve equation screen, but I loose the equation when I turn off the calcuator. When I turn it on, the equation is no longer available in the solver.

I went to setting and checked 'Save on Exit' thinking this would work, it didn't. Anyone else having this issue on their Droid 48 app on their android phone??

Pain in the butt to enter the equation each time I want to use it.

Thanks for any help out there!!
