FP4 enables mobile data even when disabled

Help Fairphone 4

Hi, I had a case maybe similar to this one:

  • I’m abroad (in EU, so I have 30Go included in Euro zone)
  • the hostel offers Wi-Fi, so I disabled mobile data for my operator (I have a single SIM)
  • and then I connected to Wi-Fi
  • I took the opportunity to update the apps and the OsmAnd maps.
  • Surprise! I got an Android notification telling me I crossed the threshold of 10Go (which I configured) of mobile data consumption.
  • It turned out I was out of range for Wi-Fi
  • But surprisingly, even with no connectivity according to the Android UI, it still used mobile data.
  • I tested again later without the Wi-Fi step, and it happened again.
  • If I switch to Flight Mode and leave Flight Mode, then I have no connectivity as expected. (that’s the work-around)

It could potentially be catastrophic: let say I am in Switzerland, not in EU, I may be billed (0.06€/Mo) if the phone does not actually disabled mobile data.

I did not investigate yet ifi it is an Android issue or a problem with Fairphone version.

Version: FP4.TP2V.C.0137.20250703

As nobody here seems to be able to confirm or help I propose you contactsupport to make FP aware.

Now that I upgraded to Android 15, I cannot reproduce the issue.
