It's a shame that this issue still exists in June of 2020 with all the latest software updates (S10+). I'm pretty disappointed cause I've just bought this phone since it's photo capabilities, but the undesired HDR makes very ugly pictures sometimes (not all the time it's true but very often).
The only "solution" was to buy an other camera app to me on Google Play (Manual Camera DSLR Pro) - it doesn't know all the bells and whistles of the stock Samsung camera app, but (at least) if I turn off HDR it IS turned off. Unfortunately I think this issue won't be fixed in the future since S10 is not the flagship device already and more than a year passed away since it's debut.
Thank you, here's hoping as i have found the post processing on my 10e to be gross. At this moment i have the 10e, my wife has my previous s8, the s7 i had before that is being used as a media player and i have had Samsung's before that all the way back to the s2.
I have always felt that each new phone improved on the camera of the one before. The 10e however is the first time i have been completely unimpressed and regretted updating.
Walk this despite the phone being advertised as having a "professional" standard camera, Samsung's advertising not my words. Anyway, still no June update but here's hoping. Thank you for your response.
