<![CDATA[No more screen during a phone call]]>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 ?

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!!

I'm quite sorry, the phone looked better without the bottom painted buttons.

I though it was my phone's proximity sensor that was broken, but reading this post I realize that maybe it is some issue with the BQ 4.5.
I mean, maybe all BQ 4.5's proximity sensor have a short life, a kind of planned obsolescence.
A similar issue happens with the screen. I bet that @x-Dub had to replace the screen because the digitizer did not respond in a wide horizontal line crossing the center of the screen. Mine has the same issue, but I have not yet change it. When I have to call someone with a 5 in his/her telephone number, I have to switch to windowed mode and move the phone app, so the number 5 stays in the top or bottom of the screen 😞 .

-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 ??

Does anyone know of an available app that indicates WIFI rate?

I think 'dataMonitor' from the OpenStore has a WiFi logger

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?

  • I can make several calls without problems
  • If I hold my hand over the sensor the screen is going black, after removing my hand the screen comes alive again.
  • Pressing the power button during a call turns the screen off, pressing it again turns the screen on again (and it stays on, not only for the moment of pressing the button)
  • Proximity-sensor in "SensorStatus" says also "no data available"

Although I originally thought that the non-original display was to blame. I changed the display roughly at the same time as OTA16. The touch decoder broke in the original display.

I hope other users can confirm that sensors are working properly and that it may be your device starting to fail or that sensors are an issue on this port.

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.

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.

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?

Maybe a reinstall with the Ubports installer is needed ?

All I could suggest for now is to try moving to the devel channel from System Settings and see if you have the same issue. My Bq is a 5 HD and has not seen the light of day for some time.
