@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_ENABLENothing else is necessary, and it survives a reboot.
Of course, these settings are reversible if needed. - 
@Eric-H
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.

@Eric-H
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

Hi @_Joao_
Have you upgraded to focal/20.4 stable ? - 
@Eric-H
hi Eric,
no I'm on 16.04 (OTA 25) but I'll look at updating to focal, thanks I'm a bit late on updates... - 
@Eric-H
Hi Eric,I switched to focal stable and the phone works much better, no more reboots when activating waydroid.
I also recovered the battery graph and I have a battery life of +/- 24 hours with normal use.
Some applications no longer work, such as the tor browser, and there are 3 or 4 sentences in the menus that aren't translated into French, but that's not a problem.
GPS works with pur map and OMS Scout server.
Thanks to the developer and the community, I use my phone on a daily basis and it works very well.
I can't wait for the next stable update, as I can already feel the power and stability of this Ubuntu focal version.

Please, may I ask your help with the flickering issue ?
Could you do a simple test ?

Wait for flickering
 - 
- Remove  ~/.cache/UBports/lomiri/qmlcache directory
rm -r /home/phablet/.cache/UBports/lomiri/qmlcache - See if there is still flickering (probably yes)
 
 - Remove  ~/.cache/UBports/lomiri/qmlcache directory
 - 
(if still flickering)
- go to sleep mode (by quick power button pressure, for example)
 - resume (by quick button pressure)
 - see if there is still flickering
 
 - 
(if still flickering)
- Close all open apps (morph, telegraph…)
 - see if there is still flickering (probably not)
 
 
If flickering is still here, redo the previous test but deleting ~/.cache/mesa_shader_cache directory this time
Thanks
