Fairphone 3+
FP3
Update from v3.0.1-t-official to v3.0.4-t-official
Not rooted
Update completed in 39 minutes with no issue.
GPS still taking 4-5 minutes to obtain first fix, but seems to be reliable after that.
Other than that, initial testing of basic functions & apps shows these appear to be working fine: wi-fi, mobile data, bluetooth, phone, message, mail, browser, App Lounge (common apps, but install not yet tested), and various other apps.
