Two quick things:
- This is a community forum, so nearly all of the people here are fellow Fairphone owners. If you require customer support from Fairphone you’ll need to contact Fairphone customer support directly. See also the forum guide on Fairphone support. To avoid confusion: none of the community moderators are Fairphone staff.
- Some, if not most of you, appear to have the same issues as described in the topic “FP2 dropping calls”. There is mention there that there can be problem with the connection of the antenna cable to the rest of the phone. One user reported that support is aware of this being the cause for at least some phones, and that if they establish that this is likely in a specific case they provide an option to replace the phone (or instructions on how to self-repair for those that dare to do that - check with support first before attempting, as this may affect your warranty).
