tried those. adaptive battery off, battery saver off, screen timout set to 10 minutes. No lock screen time out setting, the screen timeout seems to do the same thing. In battery optimisation for apps selected camera and camera tuner.. put dont optimize in those.
it could help if you could tell me if you understand the problem i am describing and am familair with it ? Because I have had this same issue with every of my 5 to 6 android phones for the past 6 years. So I presumed that all android phones do it .. Is this right ?
It was understandable in previous phones because of cam effect on battery.. , but it finally got really annoying now that Im holding a 4k high quality video recorder with a 5000mah 2 day battery and cant use it for making a 30 minute youtube vid, But it looks like there is no solution except get a dedicated camera or maybe iphone wont do this. In the meantime gonna make a 2 meter pole to use to touch the screen every 50 seconds
