Hello Lisa, I was wondering if you solved this issue yet? I have exactly the same problem. When it first started happening, I was still able to charge the phone. However, now it does not respond to a charger in any way, and it only gives this endless loop of going on and off when the battery is in there. I am wondering if I just need a new battery. But since the phone is still responding to the battery when I put in in there, I don’t know if this is the case.
This has happened to several of us. Almost every day someone reports that their F3 phone has died for no apparent reason. Fairphone has not acknowledged the issue. I sent mine to the repair centre who acknowledged that there was a problem with the motherboard and quoted £300 aprox for a replacement.
If either of you are contemplating replacement/repair of FP3 I am in the UK and have boxed example with charger, USB cable and choice of Green or Black case with 16/48 camera modules. It has never been used as daily driver as couldn’t get on with size. Have been reluctant to place for sale upon forum since Brexit, as end up having to discount 20% for EU sales with associated customs formalities in addition. I would be open to offers from UK.
@Matt2 and @Lisa4 the issue has now been resolved for me (I think). After cleaning the inside of the phone and letting it rest for a few days, I was able to turn it on after a week since the problem started. How is it going for you?
Great to hear that you were able to make it work again!
Just in case that this is a temporary improvement, please make use of this opportunity to backup all your important data. This is a good idea anyway, even if your phone is still fine. Bad things can always happen to it.
No luck yet!! Tried again following your reply, but seems well and truly dead. I have heard back from Fairphone, and they have just suggested to send it back to them, or try repair it with spare parts.
Several people have had problems with the power button, it seems to be a FP3 weak point. For most folks when it breaks, it doesn’t function at all but I’m wondering in your case if the power button is stuck in the depressed position?
Next time you plug the USB charger into your phone, press and hold the volume down button. If you then get the Fastboot screen and after a few seconds the phone loops again, I’d say the power button is the culprit. You navigate the fast boot menu by using the vol up / down keys and select option is using the power button. If the power button is depressed, navigation will also fail. If fastboot navigation works or the phone doesn’t loop-reboot from fastboot, then I’m wrong.
As you get the LED and continual re-booting, I agree with @yvmuell that this is not sudden death syndrome.
