My Kindle Touch's home button has been nonfunctional for months now. It's so annoyed when I need to go to home screen to choose another book, I must tap the back button so many times (especially, if I jump to many different chapters or links in the current book, the process will seem to be endless). I've searched all the forum but I've not found any solution to functional replacing the physical home button yet. Could someone please help me with this!

thank you!
