Since 1 week i do have problems with the Network connection. The WLAN is stable, but the fairphone looses mobile Network regulary.
Strangely enough it seems link it is more stable if I am inside a building than outside.
I did try restart but I just helps for some seconds. After that the connection is lost again.
Furthermore I am quite sure, that neither there is a problem with the Sim card nor with my provider. I tried with a different phone and it worked.
Additionally I made a available system updates.
Does somebody have an idea what might solve the problem?
