i tunes wont connect to my samsung android phone

Then you were lucky, but that is confusing since iTunes is - and has always been, designed for Apple products. It has never been designed to work with - or recognise, Android devices.

Have you perhaps been using the Apple Music app for android? See Use Apple Music with your Android devices - Apple Support.

It's not designed to do that. iTunes is for Apple's products.

To manage your phone and to add music to it, consult the documentation that came with it or look online for help with Android devices.
