small follow-up of the problem:
Concerning the loss of level of the battery that was draining in ~ 6 hours if the WIFI was activated, everything is stopped after the OTA-19 update !!
I have again a correct discharge of ~10% in 6 hours!!

Sorry for time, but I always fight with booth black screen on phone and battery rapid discharge.
-For the screen… some time it work I don't find a relation with some thing… sensor problem ?? where is data for this sensor ?
-For the battery, I don't thing it is the "wifi"…
If a reboot phone with or not wifi and do nothing it seem that battery stay ok;
but if I launch navigator, surf and close it... the battery start discharge quickly… (but not all time ! )
It is painful to characterize this because after each manipulation, you must wait 3-4 hour to see if batty is impact by the action !
What to ??

I’ve done many tests… nothing has changed about the screen that goes off completely on a call
Is there a command to have the value returned by the proximity sensor?

With regard to the problem of battery exhaustion, it seems that:
If I turn off the WIFI phone on "OFF", the battery holds without any discharge.
If I activate the WIFI or restart with WIFI on "ON", the battery runs out in 12 hours (EVEN if you switch WIFI on "OFF" !)
If the WIFI is activated and you are out of range of the WIFI network, the battery does not empty!
It looks like an application that would use WIFI..
problem: I have not installed an application since OTA18 and it is after that the problem appeared
Does anyone know of an available app that indicates WIFI rate?

@lduboeuf This is what happens: when I click on "call", the screen becomes black, if we press on it, it lights up as long as we press and turn off as soon as we release; the fact of just passing the hand over does nothing; if we want to hang up, Press on/off and quickly click on the key.
I also tested by plugging a mouse into the USB; by clicking on "call", the screen turns black and the mouse has no more effect.

the problem is there 98% of the time, sometimes I get the screen during a call but it is rare.
With the application "SensorStatus", no data on the proximity sensor (neither with the GPS which does not work for a long time, nor with the compass which also does not give anything anymore for a long time (~ after the passage to Ubport, but I am not sure))
"SensorStatus" give measurement only with Orientation, , Rotation, Accelerometer, and GPS who say: active but -,-,-,-,-, all other say "no data available",
Is there’s a problem with the sensors! ?
For the battery, it lasted at least 2 days before the OTA18, now in 20 hours, it is empty!
If TheUlpio reinstalls, I look forward to the result.

@lduboeuf This idea I like … it seems consistent because sometimes I have the screen and often the problem described above…
Can the proximity sensor be disabled ?
I’ve also noticed since the OT18 update, that my battery runs out in less than 24 hours! (even without WIFI or Bluetooth), even though it held well before… could there be a connection?

Hello,
On my phone Aquaris E4.5 Ubuntu 16.04:
After the OTA16 update, my screen turns off (black) when I receive or give a call... You can’t see who’s calling unless you press the ON/OFF button all the time, and then the screen goes on for a few milliseconds and then goes back off
If you want to hang up or have the keyboard then you have to quickly tap on the control before it goes off. Once the call is over you must either insist several times on/off or type on the black screen to find the display.
Phenomenon alas unchanged after OTA17 and 18!
Is anyone know about this very unpleasant problem ?
