Hi there! I'm Joey, and I'm happy to assist you today!
with almost all memo and text fields on the Galaxy Y -- you should be able to just tap on the screen in the location where you want to edit, and then use the delete key to delete and edit the part in question
sometimes, you may have to click a couple times to get the exact spot, but you should see the cursor move as you tap in various locations on the screen
If you have any further questions, or if I've misunderstood or failed to answer your question, please feel free to let me know… Just REPLY here at any time.
Thanks for using JustAnswer and have a great day!
Please give me a positive rating if I have helped you today so I am credited for my time assisting you.
