Hi Francois,
I asked Fairphone to prioritise my Android update as there is not much time left on my warranty and I wanted to see the phone work well before my warranty expires. I have found the battery drain to be really bad, and have not found an effective answer whilst Fairphone have promised battery improvement via Android 7 for quite some time now.
Fairphone sent me a generic response, they didn’t help prioritise my download.
I found a shortcut to the update to Android 7 by accident. The Updater told me I was up to date on Android 6 as I was awaiting the Android 7 update.
I tapped on the ‘Fairphone OS’ text on the Updater app and noticed a ‘click’ sound. I tapped several times and the phone put me in developer mode and offered the Android 7 update. The installation went smoothly, and yesterday my battery and phone performed much better!
For those of you whose warranty is about to expire, this shortcut could expedite the update process.
