I had an S3 and upgraded to the Note3. Still not able to take pictures while on a call. Other carriers allow this so I know it's a Sprint issue vs Samsung. Sprint do you know when or if you will release this restriction? I would like to be able to talk a capture images at the same time.
Thank you for reaching out to us. This is usually something that is set in place by the manufacture. There are some brands that can take photos, and some that can not while on a call. Personally I am using an HTC device and the feature does work. Please let us know if you have any other questions.
