I can recommend this post:

Noisy coloured pixels on my Fairphone 2

Disclaimer added by moderator: This post contains instructions that will void your warranty and might be futile as the same issue can have it’s cause in a defective screen instead of the core module. edit: so just after a couple of weeks it began again with the coloured pixels all over the screen, so the paper-trick is just to retards the problem… until now i have no idea. I’ll maybe check the oven, like ElKrasso proposed. Hey guys! I hope I found a solution for this prob…

hi, I don’t understand what is this " maybe check the oven".
now the situation is better, I think it is mechanical problem, I removed all module and reassembled them,

the problem disappeared.

I’m happy to hear that your problem has now been solved!
In my link I was referring the mentioned “placed a small piece of cardboard under the contact between screen and core module”. This would probably help on a mechanical problem.

ok, any pictures about this solution?

There are pictures at the bottom of the linked post.

thank you, I dind’t open the original post, up to day I have read only your answers under my post.
Yes it is like my problem, I solved it just removing all modules, also the metal cover of core module and reassembled all together.

I also changed the cover, the old one was to much “soft”, I was opening it to much often, because with android 7.0 I was not able to switch off,

now I find a solution, I have to switch on the light and switch it off.
