Sony A7IV manual mode auto adjusting settings

[gimmetherecords]

Help please. I can't work out why, when I'm in manual mode, the settings are still auto adjusting. If I set the apeture, the shutter speed auto adjusts and vice versa. The same happens if I adjust the iso. Am I missing a setting somewhere? I currently do not have full control in manual mode.

Never happened here.

Can you take a pic with your phone camera to the back lcd of your A7iv while the issue is present just to see your settings?

Have you tried to reset the camera to initial configuration? https://helpguide.sony.net/ilc/2110/v1/en/contents/TP1000616558.html

Have you updated the camera to last firmware? https://www.sony.co.uk/electronics/support/e-mount-body-ilce-7-series/ilce-7m4/software/00288927

Are you by some chance using non Sony lenses, I had this problem using a Sigma lens, I had been adjusting the aperture on the ring on the lens and I was getting the camera suddenly adjusting it's shutter speed and sometimes it's ISO on its own, actually the camera was putting itself in auto ISO. When I put the aperture ring into A and started setting the aperture on the camera this problem disappeared. It was a Sigma lens compatibility problem. So now when I shoot full manual, (which is what I do for video) I set the aperture ring to A and adjusting the aperture on the camera.
