I need you to develop some software for me. Make a software which can do a very simple thing which could remove and save a text which is written somewhere in the mobile and by just clicking some specific button that text comes back on the screen at the same place from where it was removed and save in the memory of the phone or any other memory source please don't do that in the way that a cut copy process works I need it to be very simple we write a text press something the text would remove and save then by pressing the same button the text comes back at the same position from where it was removed I would give 600-750 only for this project if I like the project very well then I will definitely provide you nice amount so why wait start biding
