My phone is a Samsung galaxy s4. Recently my home button has just been working as a back command. It doesnt wake my phone or function as a home button. I have search and tried many things. I have even backed up my phone and did a factory reset. For a while it was working on and off, but now it seems to be set permanently as a back command. I haven't downloaded any new programs recently. Just started doing it. Thank you for any insight.
