Hello @user5u3zq4Gwd6, Try giving this a try.
Go to Settings > Apps > Show system Apps (click on the 3 vertical dots upper right of screen) > Camera > Storage > Clear Data and Clear Cache.
I have developed the same issue today since upgrading to Android pie.
When zoomed in the phone physically shakes.
Switching between camera modes or photo or video doors nothing, only zooming yo 1:1
It happened to me as well. Which was today :-(
So, apparently the camera was all fine untill this morning. Believe it is a part mechanical part software issue? Coz i was just going through the camera settings....n yes the day i found out that there are two slowmo mode(which was today)....once i activated it the thing happned...plus was also changing various other settings to see what else i could do with my camera....
So i have talked with my carrier here in New zealand.....n i am really not happy with them saying it will be repaired rather than changing the phone itself! Defect is a defect! When you pay more than 1000 dollars you expect the same durability. What if the problem arise after few months again?? Each passing month will shorten the warranty period....
Other issue is, if i give my phone away for repair....i will be phoneless for few days..... so who is going to compensate that period? Really not happy.... i started using note series from note3...... n man i miss my note 3..... everyother note series after that had a issue. After warranty period ends we have to pay for the factory defects....which was not caused by us the user!
