After a battery repair from authorised service centre black edges have started to appear whereas it wasn’t visble before. They are saying that it is a feature. Can anybody clarify that
I can’t confirm or deny the dark edges as a feature, but you might try a force reboot or restart and see if it goes away. I’d also make sure the screen is fully back into place like before the repair (with respect to the case/rest of the phone), ie no excessive gaps or strange bulges.
