Hello there again,
so this is what I did:
-
followed the instructions of the waterwiki, left fully disassembled phone above heating for 4 days
-
treated it with WD-40 contact spray (to be sure that everything is nice&clean when I reassemble it
-
reassembled it with old display (the one that caused the initial issue and had the “noisy coloured mode”, see Noisy coloured pixels on my Fairphone 2)
Outcome: phone worked well for about 1 day not very intense use, then first screen flickering, got severe quite fast. The flickering could only be stopped by switching on/off the display via the power button - at one point the display just turned off without me doing anything. No reaction when I press the on/off button.
- reassembled the phone with the new display.
Outcome: phone worked well for about 1 day not very intense use, then first screen flickering. Like above, the flickering could only be stopped by switching on/off the display via the power button, but sometimes there’s no reaction when I press the on/off button. The only option I have then is to remove the battery and restart the phone as I’m not able to confirm the shutting down order.
So, what do I think is the root cause:
when I’m using the phone, everything apart from the screen is working well, the processor is running, I can use all my apps, the kamera, the headphones, the microphone ect. & so on.
I think, that my issues are based on some loose connection between the motherboard and the display (maybe the connector, which is not a part I should replace in order to not loose warranty).
What I will do is check with some other FP users if my displays are working within their phones, to eliminate the the case that I accidentally received a malfunctioning display.
If the test result will be, that both (or maybe only the new) display are working, then I see no other alternative than sending the phone in (I will be travelling for 5 months anyway and will not take this expensive thing with me :sweat_smile)
Any other suggestions?
