Thank you for attaching the screenshot as reference!
You can enable the RAW format when in Pro Mode on your camera (as precised in the screenshot).
You can enter Pro Mode by swiping the left side of your device screen and tapping on "Pro Photo".
The option is available to let you know that yes indeed it is possible to take a RAW photo format but only when enabling the "Pro Photo" mode.
Also, we will take your feedback into consideration and forward it to our development department.
I trust this information is of assistance. Should you have any further questions, please do not hesitate to contact us!
