Hello from Sweden. (New here as a post author, but have long been using the forum to fix small issues with my 2017 FP2.)
I installed the Fairphone OpenOS update to Android 9 this week.
Specific problem: can’t install new or update existing apps.
I used to download APKs (usually via apkpure.com) either directly on FP2, or on desktop Mac and then send over bluetooth to phone.
• Since the upgrade, APKs downloaded directly no longer launch. Ones that were already on my FP2 do.
• Bluetooth transfer of APKs no longer works, but JPEG and PDF files can be sent.
Feels like some sort of security setting that is blocking independent APKs.
Thanks for any advice you can offer. If I cannot run APK updates, then my FP2 is on borrowed time, just when I thought the upgrade would give me another 3-4 years of life. Ian
