FP2 random reboots - see #rebootsguide for help

I tried the hard reset today and also cleaned the cache. After reinstalling I had a reboot. So I guess I’ll return the phone now. Nothing seems to help concerning this problem :frowning: .

Hi all, I have received my new fp2 couple of days ago. Especially when using the chrome or google apps and whatsapp the touchscreen freezes and the phone reboots. This happens about 15-20 times as day. Reading the above comments I figured more people are experiencing similar problems with their fp2. Does anyone know whether this is a software or hardware problem? And any known solutions yet? Thanks in advance :slight_smile:
P.s. i haven’t contacted fairphone yet; i read that some people returned their phone. Hope this won’t be necesarry…

Its unusual for it to happen this often, when mine was doing it, it was because the SIM was a bit loose. Did you get a new SIM?

Hi All, I’ve had my FF2 for 3 weeks and it’s been rebooting regularly from day 1… It can happen anytime, when I’m a conversation which is super annoying, when I’m on the net or playing a game…as matter of fact it even reboots when I’m not using it. There’s no regularity, it can do it twice or 10 times a day, I do not have the problem some users have when it’s charging though…I only use slot one and I’ve ordered a new SIM to see if there’s any improvement but that would really be great if the team could find a way to correct that problem soon because just like many users, I really don’t feel like sending it back…

I’ve had my Fairphone for five days now and I am experiencing the reboots as well. I only have one (new) SIM in slot one. Two days ago I tried setting the frequency to 3G only and didn’t have any reboot yesterday but today it reoccured. So far it’s been two reboots right after the other within one day, while scrolling in Firefox or k9-Mail. I have all GAPPS disabled. Looks like it’s completely random… :-/

Are all devices concerned ?

Or the majority of FP2 never reboot abnormally?

Mine never reboots on it’s own and I’m sure most don’t. Maybe it’s not a bug but a production error with some phones.


Interestring. Hope Fairphone will communicate more explicitly about that.

They didn’t yet mentionned this in software issue report.

Users can wait for a fix… if it is software related… but if it as an hardware issue, Fairphone have to tell us.

@keesj ?

At the beginning, mine rebooted from time to time, always at night. Now the reboots stopped completely since I turned 4G off.

Only 2G so far since I got my FP2 (testing how long battery lasts in standby) about a week ago. No reboot yet.

Update: turning off 4g in sim slot 2 reduced reboots by about factor 3 to about 1 reboot a day, what is what I could live with for now.

Next step: I will change sim cards and go up to 4g in sim slot one with my data sim.

I am using my new FP2 for 5 days and till now I had one automatic reboot while a call was coming in. I was on my way to accept it but FP2 rebooted before I could touch it. I have only one SIM and turned off 4G now. See what happens …

@alexisju: We are aware of the reboot(s) and are working on a fix. It is always hard to determine if something is a hardware or software problem. Sometimes even it is necessary to implement a software fix for a hardware problem.

In this case we think there are different things causing the reboots and this makes finding the problem really hard. We have identified one thing that clearly causes erratic behaviour (memory corruption) and have been working on a fix for that in the last couple of weeks. This should result is way better behaviour and allow us to better identify other cases of reboots.


Hi everyone!

A week of use for me… and I have the same symptoms like Jon1.
My FP2 device restarts randomly and anywhere:
Recording a video or shooting pictures, Viewing website, Viewing or writing a message, By phone call (!), …

  • Or simply doing absolutely nothing (!).

This is very very unpleasant for a expensive device (525 EUR)

Is there a way to view the error LOGS to identify the causes of these unwanted ans very annoying reboots ?

Thanks a lot folks,

No. I have my FP2 for “1 week, 4 days, 16 hours”. No random reboot so far.


H, I have my fairphone now for a bit more than a month. The reboots occur without any regularity and already occurred when I first turned it on, not having any new apps installed. Before a reboot starts, the screen freezes and does not react to any tipping, A few seconds later the phone reboots. The reboots mostly occur when using a program,like navigation, camera or any app. So, I can say in general it occurs more frequently when being in use, let’s say it reboots about 5 to 6 times a day, some days it reboots more often. But I also observed reboots when the phone was not in use, like for instance during the night as I had to type in the pin in the morning.
I changed my sim card, but that did not change the problem. I also reset the phone to its factory defaults settings in hope that might solve the problem. Right after starting the phone for the first time after resetting, the screen froze and shortly afterwards a reboot occured. So, that could also not help fixing the problem.
I also contaced the support team. Untill now, I do not have any response. I hope they can fix the problem soon.


I just got another random reboot, the phone was charging and at 100%. I’m going to try an hard reset while waiting for feedback from support.

I understand. I guess you (fairphone) understand too that is a (very) critical issue for people who have this problem.

What i can note :

  • (Des)activating 4g network mode doesn’t change nothing
  • Logcat are not explicit about the reboot cause (no fatal issue, no systematic error messages at crash/reboot)
  • In my case, connecting the FP2 at a power source increase greatly the number of reboots (around once / hour). During an afternoon to monitoring my device via adb to save the log when it reboot, i never had so much reboots. (Usually, when my battery is 100% charged, i plug off the device, and the random reboots are less common).
  • I yet had no one reboot during almost a week… but this days is more frequent… and so annoying.

I have the same problem.
My FP2 reboots it self once a day usually when charging the battery.

I have about 1 reboot/week, but once I had 4 reboots within a day.


  • During night while charging (most of the time)
  • Laying around on the desk (sometimes)
  • During browsing (once)
  • During navigation (once)


  • 1 normal SIM in Slot 1
  • Encrypted Memory
  • 64Gb SD card (but reboots also occurred before I inserted it)

Other observations:

  • After rebooting, my screen is often oversensitive until I entered my lock-pattern. After that it behaves normal.
  • A wired sounds (some kind of stuttering) can be heard, after reboot and before I enter my lock-pattern.
