WROOM-02 Resetting

[DomalysAlexis]

Dear,

I am with the WROOM-02 and when i touch the metal cage with some metallic item it resets. This also happens when I touch the reset pin or any other pin in the module.
I performed following tests without positive results :
- R C on reset PIN
- RC on Enable PIN,
- DC/DC 3V - 500 mA

The module reset when it is powered by external AC/DC supply. The phenomenon disappears when the ground of the module is connected to earth. Moreover, ESP WROOM-02 does not reset with lab power supply.

Thanks
Alexis
