Please tell us some basic information before asking for help:
Model Name: Zenfone 9
Firmware Version: WW_32.2040.2040.23
Rooted or not: No
Frequency of Occurrence: Depends on scene and/or shutter speed
APP Name & APP Version (If your issue relates to the app): Camera
Steps to reproduce:
Open Camera application.
Switch to "Video" mode.
Frame size and FPS doesn't matter, but I use 4k 60 FPS.
Disable additional stabilizer (set to OFF).
Observe the issue:
Use camera indoors when light is not so high - notice, the stabilization is working properly.
Go outside on sunny day when light is very high - notice, the stabilization is not working anymore.
Go back indoors - notice, the stabilization is working properly again.
The same issue you can observe in Video "PRO" mode when changing Shutter Speed manually.
Set ISO to Auto.
Set low Shutter Speed value of 1/60 - stabilization is working properly.
Change Shutter Speed value to 1/400 or higher - stabilization stops working after a while.
Change Shutter Speed value to initial value of 1/60 - stabilization is working properly again.
I noticed that manually setting high shutter speed values in manual photo mode doesn't disable the stabilizer.
