Various apps not working on mobile data after last years update. Crucial apps like my carshare, public transport and weather apps are stuck on opening screen.
Hi and welcome to the community forum.
Could you report the OS Build number (go to Settings > About phone > Build number).
Do you mean that they DO work when youâre using a Wi-Fi connection?
Otherwise, I think it would be wise to perform a full âfactory resetâ.
But before anything else, please make sure you have backed up your settings and data. The reset would erase ALL your data, so you must copy documents, files, photos, music etc. onto some other device or the cloud, before you perform the reset.
All users should do full backups regularly anyway of course, so Iâm sure youâre ready

Hi and thanks! Yes I mean the various apps do work perfectly well with wifi, but not on mobile data. But that is exactly when I need those apps to navigate, open my shared car, check the weather 
or the public transport. The build number is 6.A.025.0
Do you have enough mobile data left? Some providers will give you slow data when you have reached your limit.
Who is your provider? Did you check the APN-settings?

Yes. I reset APN for both sim cards but does not make a difference. Other applications like my internet browser are working, also on mobile data and the problem with the non functional apps is persistent throughout the month on both sims I am using. So data limits should not be the problem.
Odido is the provider (NL )
When I google Odido then there are a lot of people having trouble with slow internet.
Perhaps you can try another provider.
@danielle_van_oijen I experience exactly the same! Slow apps, even unusable, for example Mywheels.
I also have a FP3 and Odido. But it doesnât seem to be an internet problem because I still have field. I am thinking about doing a factory reset because I dont know any other solutions (already tried putting battery and Sims in and out and itâs only full for 62%). Iâm very curious what you did in recent months/if you found an other solution. Please let me know!
I expect the reset will help, but in case it doesnât, or in any case, have a look at this post, which points to a reinstallation as a possibility too, and probably more effective if you upgraded to A13.

@danielle_van_oijen is it solved for you? Im very curious. For me unfortunately not. I did the factory reset and I thought it performed better, but the Mywheels app was again very slow, almost unusable. Iâm quite desperate now. Maybe Iâll try the other reset from scratch as @OldRoutard suggests, although Iâm scared it also wonât help.
Thanks for your suggestion, Iâm just quite scared to do that. It it described as being a bit difficult. I wish i could just being it to a shop in that case⌠do you have any recommendations what to do?
Have a look if a Fairphone Angel is in your neighbourhood. Perhaps the Angel can help you.

Re-reading @danielle_van_oijen 's reported symptoms I realise that this could be caused by an IP version problem. For example, if the carshare, public transport and weather apps require IPv4, and the mobile data connection only provides IPv6 (or vice versa). The fact that the browser and other apps are working can be consistent with this.
Youâll need to check a setting in your APN. Go to
Settings > Network and Internet > SIMs > your SIM > Access point names (right at the bottom)
Tap on the active APN (there may be only one)
⌠and report the value you have for the setting APN protocol.
If the current value is âIPv6â then try to change it to âIPv4/IPv6â. Youâll need to save any changes using the three-dot menu top right.
It may be that the APN cannot be modified (values shown in grey). In that case you may have to contact your provider.

Hi Lidwien and @Nadine1
I happen to be the FP Angel, however I do not have any knowledge or experience on/with this. @Lidwien, you are also not super far from Nijmegen, maybe @Nadine1 could come to you?
Sorry I cannot help with this!
I hesitate as I read the provider is Odido. There are many people having problems with Odido.
My first idea is to disble 5G and see if that helps with mobile data.
Hi @OldRoutard thanks for you response! Sorry for my late response, I didnât see your message.
Today I had to get the apps Eduroam and Authenticator and to install them without wifi was easy and fast but to use them was again difficult, they were too slow to function.
I checked what you said and it says APNprotocol IPv4/IPv6 and Roamingprotocol IPv4.
So that means this is not a problem, right?
I also think its the phone and not the provider because i feel like it started happening around the time of getting the update.
Please let me know what you think!
Kind regards,
Nadine
Hi Lidwien, thanks for your response. What do you mean with disable 5G? I see my voorkeursnetwerktype is called: âautomatisch 2G/3G/4Gâ
I guess that you are currently roaming. Since Eduroam is there to provide a Wi-Fi access, you shouldnât need to turn on mobile data at all (so the IP version is irrelevant to this case). So I suggest:
- turn OFF your mobile data
- turn ON Wi-Fi
- Using Settings > Network and Internet, identify and connect to the academic institutionâs Eduroam-enabled Wi-Fi network. You will be asked for the authentication previously supplied by your home academic institution.
OR
Use the geteduroam app. Having downloaded and installed that over mobile data, you should then switch to Wi-Fi as outlined above.
You can also contact the IT service of the institution that you are visiting for additional info.
Oeps, I forgot that a Fairphone 3 doesnât have 5G.
Sorry maybe I was unclear, I was at work there and in order to get on the wifi i was indeed adviced to install the geteduroam app, and in this app you have to fill in your name and password but the geteduroam app didnt work because my (still on data) phone was so slow and someone had to help to get wifi without using the app.
Once i was on WiFi no problem at all anymore. The problem of slow apps is only there when i use data.
