        @eheintzmann hello, do you have any other reboot bugs since your last message?

            @eheintzmann Is your phone up to date? I haven't had any random reboots for quite a while now.

              @arubislander Yes, my phone is up-to-date. This is probably a surya only issue.

                @eheintzmann oh, this is the Xiaomi section. I mistakenly assumed it was the Pixel 3a section. That devices used to have this same issue.

                    Hi @_Joao_

                    A week ago, I tested a script found in this forum :
                    https://forums.ubports.com/topic/6211/howto-alternate-way-of-saving-battery-when-using-4g-lte/70?_=1700961879422

                    As expected, autonomy of my phone was improved.
                    But as a bonus, its stability was also improved.
                    Indeed, I didn't see any random reboot for one week !

                      @eheintzmann hi
                      Interesting... Maybe the battery is at the end of its life. I've been asking myself this question from the beginning.

                        Maybe yes

                        But
                        I've seen random reboot when plugged
                        I didn't see ant random reboots in airplane mode (plugged or unplugged)

                        So maybe not…

                          @eheintzmann hi, the script works to improve battery life, but it doesn't launch with the terminal but by restarting the phone and unfortunately the phone keeps its untimely restart bug. I'm waiting for the stable version of focal to redo a clean installation to see...

                            Hi @_Joao_

                            I tested only the 20.04/focal version of this script.
                            In this version, it uses a systemd service to automatically start/restart.
                            No reboot, nor manual, intervention is needed.

                            On my surya, with this script activated, I've never seen any random reboot.

                              Possibly, I found something. Possibly…

                              Just after a random reboot, in the file /var/lib/systemd/pstore/dmesg-ramoops-0, there are these lines :

                              I found similar logs for the FairPhone 4 at :
                              https://gitlab.e.foundation/e/backlog/-/issues/6096

                              And the solution of the e-foujndation at :
                              https://gitlab.e.foundation/e/devices/android_device_fairphone_FP4/-/merge_requests/23/diffs

                              So maybe, setting two properties will solve the problem :

                              setprop persist.vendor.ssr.enable_ramdumps 0
                              setprop persist.vendor.ssr.restart_level ALL_ENABLE

                                Before settings properties :

                                After settings properties :

                                $ cat /sys/bus/msm_subsys/devices/subsys*/restart_level

                                Let's see if there are still random reboots in the next few days...

                                  @eheintzmann it's all a bit complicated for me... But actually this report seems logical because in airplane mode the phone does not turn off by itself

                                    Since I installed UT on my phone (xenial first, then focal afterward), I have never taken 24 hours of uptime.
                                    But with the changes indicated in my preceding posts, I have reached 3 days of uptime today.

                                      Hi @_Joao_

                                      If you also want to test this solution, just type in a terminal these lines :

                                      setprop persist.vendor.ssr.enable_ramdumps 0
                                      setprop persist.vendor.ssr.restart_level ALL_ENABLE
                                      

                                      Nothing else is necessary, and it survives a reboot.
                                      Of course, these settings are reversible if needed.

                                        Hi Eric, I'd like to thank you and the developers because the previous operations solved the problem; the phone no longer restarts by itself and I've gained +/- 6 hours of autonomy, which is really cool.

                                        Thanks again and best wishes for 2024.

                                        Note: if I can help with other tests to further the community, I'd be delighted to do so.

                                          You are on xenial, aren't you ?

                                          Do you see, sometimes, UI flickering ?

                                            yes xenial.
                                            yes, it happens sometimes...I restart and the symptom disappears.
                                            there's also a bug when I launch waydroid several times, the phone crashes and restarts by itself.

                                              It happens on focal too.
                                              I am trying to understand where this flickering comes from.
                                              If you have any ideas...

                                              there's also a bug when I launch waydroid several times, the phone crashes and restarts by itself.

                                              I think this is fixed on focal.

                                              In case you are not aware, we have now a 20.04/RC channel for surya
