Space between OLED and orange Plastic

Hello,

Im New in the world of ER301

I recieve my unit Yesterday second Hand all is fine . But one Thing i notice is the smaller orange Screen Lens i can Push it a little Bit down on the left Side . 1-2mm . One the right is tight . I have Look between Panel and PCB i have See the amount from the OLED Display on the PCB is to Short to Puch it Up. My questions is have that only my unit or is possible from the building thats happend?i have little Bit dust between OLED an the orange Lens .

Cheers
