I have this fairphone for more than 2 years i think. Recently i change my operator and so my SIM card.
It has worked fine for 1 month and very often i have my fairtphone rebooting or freezing.
When i remove my SIM i find that it works better but not perfectly with freezes and rebooting also…
What are my options ?
Thank you. Clearly it is not a matter of SIM as without the SIM the Fairphone starts but freezes around 1 min later …
i have done a Factory reset but with no luck.
I don’t know what to do ? is there somewhere i can make it repair (I live in Lyon) ?
Use this guide for demontage Fairphone 3.
Connectors are often cleaned with isopropyl alcohol or nay pure spirit around 90 %.
Ensure you tighten the screws evenly before you give them the last tighten, and not too tight.
You may also check the stainless springs on the core module and their contacts on the display.
