After a few days of stability I got a random reboot today, and the last_kmsg log file says it’s Aix Weather again. I’m giving up on it and will try Your local weather instead to see what happens. Below the relevant segment of the log file.

After opening the serialconnection with my DIY-shield (attached on the extension port of the fairphone) the FP reboots a few minutes or seconds later…
I logged with adb wireless because the reboots only happen when no usb cable is plugged in…
here is the last log I get with quite some errors…

Cannot access the file, sorry. You need to open it with Wordpad (not Notepad) and look for words like “tainted,” “page fault,” “unknown symbol address,” “undefined instruction,” “freezing user space,” or any other suspicious message in the file. Then you check for the last app showing activity before the suspicious message, it’s usually the culprit one. The segment you copied a few messages above unfortunately doesn’t offer me any hint of a problem, but my knowledge is limited, maybe somebody else can see something wrong in it?
Now it should work…
I allready know the app or better the activity causing this unwanted behavior…
It´s the opening of a serial connection to the DIY-board…
This is harder to debug because there can be a hardware failure involved, for example, the serial connection could be overloading the i/o circuitry, then causing system failure.
What do you mean with overloading ? Draining a to high current?
I don’t think this is the case because the shield is always attached to the FP and so is draining always a small amount oft current…
It only restarts when I open a serial connection and the usb-cable has to be unplugged …
I thought the baud-rate could be the problem but i don’t think so … i mean with a usb-cable attached it works and so we can forget this point…
This hadn’t happened for a while, but has just started again. I thought it was Facebook, but I removed the app and it’s still happening with any app or none - usually after I’ve been using the phone for a little while (15 minutes?) but the phone isn’t hot (and sometimes it happens when im not using it).
Not sure if it’s since the latest update or had started before then.
Does anyone have any ideas? Bear in mind that I’m a technophobe/luddite so won’t understand any technical terms! Thanks!
Wanted to say that after some time observing when reboots occurs it seems to be link to silly Facebook app. Also I experience some reboots with Waze as well.
Anyway, thank you for the confirmation, gonna backup, reinstall OS and try again to leave with F-Droid only.
I’ve been using SlimSocial as a replacement for the Facebook app. it doesn’t have all the features but it works well and respects your phone, battery and privacy.
Since I ordered the fairphone, I experienced reboot randomly a lot of times a day.
Yes I did contact the support, and after a long testing (1 month) they proposed me to change my phone. Process who takes between 2 and 3 weeks more.
Guess what ! After 2 weeks using my “new” fairphone. It restarts to reboot randomly few times a day.
Perharps anyone here (user please or fpteam experienced in the topic) could hepl me to find the bug and reslove the problem.
I am using Fairphone Open with few apps I can list if need, provide any screenshots and everything you want. HELP HELP
Please avoid Fairphone team messages wich just repeat the support I did have yet. Thank you
I experienced only very few random reboots in the entire 2 years of owning the phone. But maybe the rebootsguide can help you: ✏ A little Guide to... Random Reboots
I might have the same problem with Titanium. I would like to keep it though and not replace it with My Backup. In the Wiki you mention that it’s possible to disable the System UI backups. Could you explain how you do that? I think I don’t really understand what you mean by that.
It’s an option in settings but available only in the PRO version, which I didn’t have since I don’t have Google Play (FP Open). I got the information from this thread that discusses the same problem and offers solutions.
For others who might have the same problems as me:
I created a filter in Titanium Backup in which I labeled the Apps System Ui and Alarm. I then chose the inverse option so all other apps got selected by this filter except for these two. I then applied this filter to my scheduled backups.
This solved issues with the alarm app crashing (freezing the whole phone, only restart helped) as well as freezing issues in general and resetting my background to default (most probably, hasn’t happend again so far).
However this didn’t help with Whats App randomly rebooting during video calls. I hoped this would be solved by this as well. Maybe excluding Whats App from Titanium would help but I really want a backup of Whats App.
So my next try is to disable the scheduled backups of Titanium totally. If this stops the random Whats App reboots I will need to look for another backup solution.
i mean with a usb-cable attached it works and so we can forget this point…
