after having some of the earlier Fairphone troubles, necessitating two earlier hard reboots, here’s another one. Over the past days the phone gave me the message “Process system isn’t responding. Do you want to close it?” and gave me the options “Wait” or “OK”. Whatever one clicks, no effect, the screen just goes black.
A reboot via recovery mode does not seem to solve the problem, it just restarts after a number of minutes (and drains the battery). The phone is unusable.
