Hi all,
I bought my FP3 for Christmas 2020 and since the beginning I had a problem of unexpected reboots (around 5-6 times a week).
I opened a ticket but after three months and a half of testing (and one pit stop in the Fairphone technical lab) I realised the problem depends on having two SIMs in the phone.
There is another topic similar to this in:
https://forum.fairphone.com/t/fp2-reboot-due-to-dual-sim-cards/28608
but it’s closed and it relates to FP2.
I’ve tried many combination of SIMs and slots and these are the results (below I’ve named my two SIMs, “SIM1” and “SIM2”):
Slot1: SIM1
Slot2: SIM2
around one reboot a day
Slot1: SIM2
Slot2: SIM1
around one reboot a day
Slot1: SIM1
Slot2: empty
no reboots
Slot1: SIM2
Slot2: empty
no reboots
Slot1: empty
Slot2: SIM1
no reboots
Slot1: empty
Slot2: SIM2
no reboots
So I’m pretty sure the problem is linked to having two SIMs in the phone at the same time.
In the thread I linked above apparently the problem was solved configuring SIMs to only use 3G instead of 4G. However, I don’t want to loose the possibility to use 4G and I’m not sure that a FP2 workaround could work on FP3 as well.
Did anybody experience the same issue? If so, have you find a way to solve it?
Thanks.
Regards,
Massimiliano
