My note 10 plus takes absolutely terrible selfies and pretty bad photos on the main camera as well. With all the praise that's been piled upon this phone's camera, I was expecting to be wowed but I'm not even pleased. Maybe I have a faulty device??
My S9 plus definitely took way better photos.
2:30am or 2:30pm has very little effect on uploads, most of the time only the peak speeds are affected by off peak vs peak times.
They are almost always stable.
