I replaced screen / front sensors and home button all working fine. Apart from no sound when answer a call / works on speaker but not to the ear any ideas? Thanks
I would do a Recording Test using Voice Memos to see if the earpiece will work. If that did not work, attempt to Restore the phone. EDIT Check the Earpiece section and make sure the Gold Contacts are lined up and the screws are in the correct position. Let me know how it turns out.
