Please tell us some basic information before asking for help:

  1. Model Name: Zenfone 7 Pro
  2. Firmware Version:
  3. Rooted or not: No
  4. Frequency of Occurrence: Always
  5. APP Name & APP Version (If your issue relates to the app): Camera


I open up manual mode, set shutter to 1/100th, leave everything to auto -> photo is very overexposed (as if metering is not right). I change shutter to auto, phone sets it to 1/100th, everything is on auto -> photo is normal. Now I notice that in full-auto ISO is 3 times less. I go back to manual 1/100th shutter and set it to lower ISO -> photo is normal (as expected).

The manual camera mode manual shutter only mode sets ISO way too high in good lighting conditions. See screenshots.

I just realized how many shots got ruined by this...
