I have the same issue. But it can’t be beacause the games are too demanding, can it? Like Crossy Road makes my FP2 crash /freeze’n reboot. Even my iPhone 4 managed that…
Hello,
I have my Fairphone 2 for 3 months now, and I first experienced that problem with Tomb Raider Go. The game runs fine, very decent framerate, but it makes the phone heat a lot. And after ~10 minutes of playing, the phone reboots by itself. And now I have the same issue with Pokemon Go. I play also Pocket Morty, which heats the phone too but maybe it’s less resources consuming because I don’t remember having reboots playing it.
I get that the phone heats a little when playing, my computer does the same, but there it’s a lot, has the Fairphone such a conceptual heating problem that it can’t handle games ? That would be disappointing, and also weird since once again I don’t have framerate problem so it seems the hardware can run those games easy. Am I the only one experimenting this ?
Thank you
Same here,
I play Pokemon Go, and after a few (random number of) minutes, the game freezes and the phone reboots. At first I thought it was overheating, but it seems to be more random: this morning it happened after 1-2 minutes while the phone was still cold, and I just played for about 15 minutes without problem.
I moved your post here to avoid duplicates.
Looking at the comments here so far it seems there is only a problem with a few specific games, most of them seem to have a “Go” in the title. Whatever the “Go” means - I’m sure you’ll tell me - is probably what causes the overheating.
Also you could try this workaround:
Hello!
I am also experiencing the same problem with reboots when playing Pokémon Go. I play other games on the phone as well (The Hobbit, clash of clans etc) without problem. Only one that has caused multiple reboots is Pokémon. I don’t think it’s an overheating issue because I can sometimes play for a long time without reboot and other times I just start the game and get a reboot straight away.The gps is on at all times with the game, could this be causing the reboots? I read about others having problems with their phones when using gps…
I have loved having my fp2 despite the various small bugs but this is really frustrating. I like playing all sorts of games and it’s no fun if my relatively new phone can’t handle certain games… Hope it’s not a hardware issue 
I guess you are referring to this thread? The issues described there are only relevant if you use Open OS.
I never had a reboot, but with some very cpu-consuming games the phone gets very hot. What I do: Put the phone in the fridge for a few seconds or hold the back against a (dry) cold water bottle. The phone is cold again for a few hours. 
Thanks for the tip on cooling down the phone. I have experienced it getting hot when playing games but it hasn’t rebooted because of that. And with Pokémon it doesn’t get hot, it just reboots randomly.
And it was this topic: https://forum.fairphone.com/t/fairphone-2-rebooting-while-using-gps
But the two problems might have nothing to do with each other.
And this is not that big an issue, just quite annoying 
Late reply, but the “Go” in the title is just a marketing gimmick, it does not imply any specific gameplay or technical choice.
As for the graphic quality, it’s not possible in all games, like Pokemon Go

But what some people say is right, with Pokemon it does not seem to be a heating problem, the phone sometime reboots just 2 minutes after launching the game, and the phone is still coldish… So yeah I would be more inclined the accuse the GPS, seeing that other thread and how Pokemon Go use it intensively.
Same here. Basically you can’t play PokemonGo on the Fairphone. The reboots ruin it. I’ve been having reboots issues before (about once or twice a week) but support never replied to me when I told them. With PokemonGo it’s just unacceptable, after a number of minutes it freezes and reboots.
My FP2 often reboots when I turn on 4G. As long as I’m on 3G/2G only, it works fine. Maybe that’s your problem with Pokemon Go as well…
I would say that it’s not because of the gps or even 4g. I play a couple of games and this issue mainly occurs with one of them, namely Walking Dead: No man’s land. As far as I can tell it’s somehow related to quite heavy network use and somewhat demanding grafics, so my bet would be that the cpu overheats.

In agree, Pokemon Go doesn’t crash for me if the gps isn’t enabled, (though it’s pretty useless to play without gps).
Check out the thread on gps issues there may be a workaround with using microg? I’m still working it out.
It seems that the reboot + warming (when we get enough time to play) still occur and I am now facing other issues (freeze or white screen when catching).
I tried several things like removing/adding the GPS /Wifi… but nothing works.
FP2 is supporting hardly the game Pokemon Go (and anything else Go).
I think that if I use the OS I could get chance to use the app properly but I do not want to try because I am not comfortable with that. I hope a new update of the Android will solve it.
Who knows if this kind of issues has been raised to the FP IT developers? Is someone from FP can prepare some information about the issues that we can face with the FP2?
Thanks in advance!
How did you reduce the graphic quality on your Fairphone ?
Thanks
Hello! New Fairphone 2 User here.
The phone crashes regularly when using games like Galaxy of Heroes or Pokemon Go.
So it seems this is a problem regarding hardware-demanding games causing the OS to crash.
A bit disappointing to see that behaviour 
Hello !
For me as well the FP2 reboot with a random frequency when I’m playing Pokemon Go ! Very frustrating I hope that the next software update will stop that.
I think like other people that the problem maybe come from the Gps, because when I’m using Waze the phone reboot a lot too!
Hi all.
I just want to join the choir. My FP2 also reboots a lot during Pokemon Go. Both while it’s cold and warm. I have not found a fix to this.
Also I’ve experienced unwanted reboots whole using facebook, and just plain old chrome. But they are not as frequent as they are when I try to play Pokemon Go.
Normally I wouldn’t reply like this, but it looks like a lot of users have this problem, and I just wanted to add to this.
I have the same issues. Random reboots and high heating of the CPU.
The overheating occurs not only during demanding games, but also during charging of the phone (tried different chargers to no avail, I also have the Fairphone 1 charger, same with it).
The random reboots seem to be just that, random. But they occur more often when playing demanding games such as Star Wars: Galaxy of Heroes or The Walking Dead: No Man’s Land. Specifically in the Star Wars game, it seems to happen mostly in periods of high network-usage.
Any suggestions on solving or at least lessening the problem yet?
