On the front camera of my Z Pro is already a lot of dust.
This makes the pictures even worse than they already are.
I've already tried to open the case and remove the dirt.
Unfortunately, I did not succeed.
I tried it as described in this video. How to replace front cam
I was worried about damaging the display.
Can someone give me some advice on what to look for when opening the display?
Is there a special trick to open the device without destroying something?
Don't touch display. You need remove back case, disconnect battery, remove motherboard and remove camera, then clean from dust. You can use compressed air for cleaning keyboards etc
It looks very simple in this video.
I did not succeed in removing the case.
But I did not want to use too much force,
because I was worried that the display could be damaged.
Not only those two screws holding back cover on place. You need remove those two screws and then use suction cup on bottom of phone and gently separate screen unit from back cover.
