For the last 3 weeks my phone switches over to loud speaking within 2 seconds of calls incoming or outgoing. The green light on the speaker button is not lit up. When I do turn it back to handset it again changes back to speaker phone within 2 seconds.
I have tried resetting my phone, using in safe mode and by removing recently installed apps and nothing is fixing this problem. Any suggestions as my phone is pretty useless as it is?
