I found this issue on the GitHub Unable to set quality when taking still photos · Issue #146 · dji-sdk/Mobile-SDK-Android
Now I’ll say I am not a developer or anything so I may be misunderstanding what is being said said there and please correct...
The most questionable spec is a larger sensor. What’s the next step up of mass produced sensors? APS-C? Seems very unlikely but I said the same thing about the 4/3 so who knows.
