Every time I make or receive a phone call automatically goes on loudspeaker?
The iPhone switches to speaker if your ear is far away from it. This is a setting linked to the proximity sensor. Sometimes this happens when you push the earpiece even a little bit out of its range, therefore you have to place it close or on your ear. You can turn the feature off by following these steps with IOS 8.1.3
Go to Setting/General/Accesibility/Interaction/Call Audio Routing/Set to Headset not Automatic or speaker. Then reboot the phone.
I was having so many problems finding the setting on my iPhone 8+ and I finally found it below the “general settings” on the fourth option down is “accessibility” Clicked on that and then under “physical and motor“ I clicked on that and went to “touch“ after “touch” I went down to “call audio routing” and switched it to automatic instead of speaker and it fixed the problem of always going straight to speaker automatically. All the other blogs kept telling me to find the setting under general and call forwarding but on my iPhone 8plus it is under “touch” and all the way down to “call audio routing”.
