Brand new out of the box Fairphone3 FP3, applied latest December 2019 update, even before putting any google/accounts to it. So far so good.
Then, just discovered a very frustrating malfeature. Since I actually only use public wifi places, buggy feature of FP3 is that when in airplane mode, and turning wifi back on, it only seems to list wpa2 (wpa?/wep?) - so encrypted only wifi networks thus no unencrypted wifis, even when sitting right next to the access point.
when briefly deactivating airplane mode, then quickly connecting into the public unencrypted wifi, and re-activating airplane mode, briefly killing public wifi as well, but quickly turning back on via the wifi icon, it very briefly shows back the unencrypted public wifi name and seems to maybe somewhat connect to it, just to lose this unencrypted public wifi connection again within seconds and then never making anything of public wifis again ever after.
wanted to force some wifi call tests and so on and then discovered this weird and buggy behaviour
