Flickering reflection on phone lens render

[jingles]

My phone render has a flicker in the top glass lenses. The main source of this issue is because the phone has Dynamics enabled to add a more natural movement as it re-positions. I've tried tweaking Octane settings to remedy the flicker AND dynamic settings to ensure it has stopped fully but without luck. The wireframes are buzzing ever so slightly so i can tell there is slight movement, though its not visible on screen.

Hoping someone can help.

Octane Settings;
- Tried Direct Lighting and PTrace with multiple diffuse/spec/glossy depths from 3-6.
- Increased samples

Dynamics:
- Linear velcoity Threshold: 15cm
- Angular velocity threshold: 25 degrees
- Mass Density 5 / Rotational Mass 50%
- Force Follow POS: 30
- Follow ROT: 20
- Linear Damping 50%
- Angular Damping 25%

Thanks

Hard to tell from your video but it looks like you need to use the hotpixel removal setting.

Too Big Scene Scale?
Need More Value --> Ray Epsilon

Nearest Surface ?

Duplicated Object?

Thanks for the replies...will try hot pixel.
Not sure about scene scale...Objects are about 160 cm / units and project scale is 1cm.

What do you mean by nearest surface?
Any tips on approaching Ray Epsilon values?
