Just rereading this thread, people are talking about reboots. I’m getting compete lockups that require a 10 second power button press to recover from. Are they the same thing for this thread? Or different problem?
I have both. To me they seem interchangeable (if I suffer more from one, the other does occur less)…
I hardly ever see a random reboot, and when I do I feel like it was Facebook doing it.
I just had a lock up, and in this case (and it’s happened like this a few times now,) you can really imagine it’s a CPU problem. The phone becomes oddly slow. Not in that everything is taking ages to load or swap to, but scrolling mostly. I was trying to browse this thread, and I stopped being able to flick down to make it scroll quickly. Instead I had to drag down and it would slowly scroll the page at the same rate as the finger. After posting my last message on here, I locked the phone via the power button, and then wanted to check the time. Pressing the power button did nothing (as normal in the lock ups) After leaving the phone for 10 minutes, it was still locked up ad i had to 10sec long press and restart the phone. It’s really frustrating!
AA processor here. I had freezes for months (I think between around 1 year to six months ago). The phone froze and I had to reboot it holding the start button for many seconds.
In the last months I have not had this issue anymore but I have reboots instead. The phone freezes (similarly to what it did before) and after a few seconds of freeze automatically reboots.
It is already better because at least if anyone calls me or the alarm clock is set the phone is never accidentally shut down.
Did you do anything to fix it?
I tried changing the cable and I exclude it to be facebook related as I do not have facebook. I had no time to test other possible explanations.
However I have a personal theory that involves the battery because I feel like most of my reboots happen when the phone is on charge or almost fully charged.
I guess there might be many issues related to reboots and freezes so I doubt a general solution exists for everyone.
The same for me. I had several reboots every day. After an update around Dember (I am using FP-OS) I had no reboots anymore at all. I have the -AA processor version.
After 3 weeks it rebooted 1 time :-/
So, I choose “AB few reboots (<1/month)”

Maybe we should redo this poll after every update. I remember with the first few updates that always some people said their reboots were fixed or got better while others said they started with the update or got worse.
I have no idea if there were already AA and AB type processors within the first FP2s, but if so then that could explain it.
On the other hand I’m sure the hickup-reports include the processor info, so the software team @Fairphone has much more detailed and significant data available than we can gather here with polls.

When I had the freeze issue it changed significantly after each update: sometimes it improved sometimes it got worse. I think the freeze frequency ranged from more than one per day to less than one per week (on average) according to the different updates. Then at some point I started having also the reboots and after a while I had no freezes anymore but only reboots. However I have the impression that both of these issues happened in the same situations (i.e. mainly fully charged battery). I would be curious to make a poll and ask everyone to report the battery charge when the phone freezes. I would try to guess it to be quite high.

There were. I’ve got one of the first 17k (whatever the exact number was) and have an AB processor.

I have an AA procesdor and have sometimes reboots 39 since hiccup and it is getting beter the last months
AA processor, once a week.
With lolipop, mostly after extended time of non use (~30 hours) and during heavy usage (device case temperature well over 28°C)
AA processor
Reboots in 3 months usage:
-
3x OSMAnd als Navi mit und ohne Ladekabel im Auto und zu Fuß. Die Klemmhalterung im Auto kann permanent auf den Kameraknopf drücken weshalb ich das Gerät dort nur sanft einklemme. In diesem Betrieb wackelt das Fairphone kräftig, vielleicht verliert es dadurch Kontakt zum Akku?
-
2x Synthesis: 1x kurz nach dem Neustart aufgrund von OSMAnd. 1x bei schneller Bedienung der App, schneller als sie reagieren konnte.
So it might be due to high processor load during navigation or operation of synthesis.
As the reboots are not too often, I will not take counter-action for now.
Running Fairphone Open 5.1 (17.03)
AA and reboots between 2 and 3 times per day.
After trying everything else, I recently did a factory reset which solved many smaller problems but not the one with the reboots. I am now on FP Open OS. The first day went by without reboots, but after installing Telegram and Threema they started again.
So far they happen almost only while browsing (tried the pre-installed Browser and Lightning, no difference). Before the reset OSMAnd with GPS on was particularly catastrophic as well, haven’t tried that yet.
Yesterday I activated root and downloaded Kernel Adiutor. I could see that one of the processor cores was permanently off and one was switching off-on all the time. I turned all of them on now and changed the settings according to Antimailer’s post above, so far it’s fine and the phone is stable. I’ll update this post once I’ve tested for a few days.
These days I had a marshmallow reboot after about 4 or 5 days of uptime running a game app.
It looks to me as if there’s a resource leak.
AA Processor, had black screen lock ups semi-randomly and possibly CPU related (whilst installing updates?), and separately, restarts without black screen freeze, ONLY whilst 4g activated and in heavy use typically GMaps and spotify with 4g signal. Neither ever when left alone on airplane mode (overnight). Facebook Messenger installed but tried uninstalling Facebook itself, didn’t seem to fix
Since 6/M update, no black screen lock ups, but an instance where everything started being really laggy - have now just done a factory reset with cache clear to see if helps.
When tried 4G on have seen 1x restart with screen on and and heavy use as before
@DjDas you mentioned 4G, are you saying 4G made yours better!?
Anyone, Does the 4G being on creating random reboots potentially cause this behavior in conjunction with CPU overload - any insights? Worth changing CPU settings? Is it possible to check the settings before root please?
@dwinter: no, it’s the opposite, with LP and 4G enabled the phone became highly unstable and reboots were very frequent; moreover there were weird behaviors after passing from 4G to 3G, it seemed there was a sort of “stabilizing time” in which reboots occurred and after an undefined amount of time the situation became more stable.
Unfortunately at that time there wasn’t the Hiccup tool, and I also was on Open OS when it appeared on new OS versions, so I couldn’t provide info to Fairphone.
Eventually I switched to beta M so I started to try different scenarios on this OS version, enabling Hiccup on it in order to collect crash reports; now 4G works without any problem (on both SIMs) and I have no reboots after I downclocked the CPU to 1497MHz using Kernel Adiutor (please see my previous post to see when I did the downclock).
The only poweroffs occurred since then, were due to battery outage.
Bye!
