Thank you for sharing your suggestions here to add flash to the 0.5 camera mode on the Samsung Galaxy phones.
We appreciate the time and effort you put in to share your valuable comments. This helps us improve our products, apps, and services towards enhancing the Samsung Galaxy experience for all.
In the meantime, the current Samsung Galaxy phone camera has a flash that you can turn on, off or on auto.
If the lightning bolt has a slash through it, it is always OFF.
If the lightning bolt has an "A" by it, it will only flash if the camera thinks you need it.
If you want it to always flash, you need to change the flash settings to just the lightning bolt.
