Situation

  • Battery level: >80%
  • Handset was inside house, in pocket of trousers (i.e. temperature well within operating range)
  • Handset just unlocked (after having been locked for a longer time)
  • Taking a photo, camera uses flash
  • Sailfish OS 1.0.5.xx (did not happen to me with previous versions)

Problem

  • Screen goes black
  • Charging symbol may appear or for some time (half a minute?)
  • Thereafter the handset can be unlocked "normally" (including entering the unlock code and entering the SIM code)
  • Photo has not been saved.

Alternatively to showing the charging symbol, the handset may shut down completely (i.e. it has to be rebooted).

Occurrence

Meanwhile several times since updating to Sailfish OS 1.0.5.xx. Following I could take photos with flash (but I am not sure whether flash simply did not output as much power as before and therefore did not pull down the system's supply voltage so heavily -- if this is the cause of the problem).

PS: I am aware of https://together.jolla.com/question/22872/bug-taking-picture-with-flash-causes-shutdown-in-cold-temps/. This however explicitly talks about temperatures below 0°C.

I had this today. I could reproduce it 5 times in a row. It is not a temperature issue because the phone was at room temp. and that was 20°C for a few hours already. Battery level was at 50%. There was no charging symbols, the phone went instantly off.
