Thank you for your responses
Not trying to get rid of an app, but to build up internal phone storage space.
And I'm not talking about a MAC Program App (btw I have an Android smartphone). My concern was the app deactivating after placing it on the SD memory chip.
After testing and trying, I see that the chip works very well (like a floppy disk). I do this to free up space for internal phone storage to allow downloading more apps.
The touch screen is very good on the phone (but not 100%). This is a new technology to me which I'm getting used to.
Thank you again.
