I am facing so many issues after updating device to latest November update. Some of them which I noticed are as follows
1. Torch function is not working.
2. Video flash not working.
3. Pictures taken for near subjects with screen flash or led flash very shiny and it captures only reflective light and subject is missing at all.
4. USB tethering option does not work.
5. There is sudden dropout in battery percentage.
6. Charging time is very high.
7. Battery backup is very poor.
8. No any improvement in low light photography performance pictures retains grainy and just VGA camera quality like.
I personally think that this recent update is of no use infact it brought many big problems.
I have tried almost all options as adviced in this forum or suggested by Samsung care executives but no result. To solve this either you have to go to the service center or wait for the next update. If you have not updated than kindly stay on earlier version till problem solved.
As I got to know the problems you mentioned above is sort out by pushing November 2019 security update again. You may update to get rid of it. As far as I am concerned I had also same problems for which I got it repaired in service centre.
