M_Dammer posted here Release of 16.07? that there exists a code aurora patch for the unsolved RTC bug (wrong date/time after reboot without connection: https://forum.fairphone.com/t/fp-open-os-clock-resets-after-reboot/17635).
Is there any possibility to get this patch for a workaround and if not how could we/I help the development to find the solution faster?
Update: Maybe this suggestion could be a solution for the next version: https://forum.fairphone.com/t/fp-open-os-clock-resets-after-reboot/17635/35
Please force fixing this bug.
