HI everyone. My husband has an iPhone 6s and I have an IPhone 6S Plus and we are both really disappointed with the camera quality. 9/10 times the photo is blurry on either phone. No sign of the image stabilisation that is suppose to exist with the Plus. We have tried every troubleshooting option to no avail. Very disappointed that photos of our new son are blurry and unusable. Any assistance would be great! Thank you!
Back to your issue. Try the suggestions below. Tapping on the subject helps, particularly if there is great depth of field. If still unable to take good photos I would go to an Apple Store and have them test the phones.
