Re: Unable to finish phone calls

Indeed, my phone has silicon case and protective glass in front. Which one could possible cause this problem? I have had etui and glass for 1,5 year or so and the problem emerged 1 or 2 months ago.

Remove it and check again.

Re: Screen goes black when making a call

I couldn't believe how many same complaints I saw when I finally typed in this problem with my phone, I totally believe that it's simply a Sony cheapdeal with a failure software and they really scammed their customers by selling basically. And it's all started in 2015 when people started realizing it, yet 2 years on they still hasn't stopped. Well done Sony u just really up and they probably gonna get some insurance income as well!!

Re: Unable to finish phone calls

The short answer is...I don't know.  The act that there are SIXTEEN pages of people saying the same thing is evidence of some sort of design fault.  Virgin admitted that they have had a large number of people complaing about this phone and the M4 Aqua.  Sony aren't much help, the operator said that I should do a 'software repair' with a USB lead...so I did.  Result...NOTHING!!!  Neither Sony nor Virgin seem to give a stuff!!

Re: Screen goes black when making a call

I am having the same issue. When I dial a number the screen goes black and it doesn't turn back on until I hold the power button and volume up to reset the phone.
I have done everything except a factory reset.

Re: Screen goes black when making a call

Hi Adeelz

I had a factory reset done by the staff in the Virgin shop which is whom I have my contract with.  The manageress gave me the phone back and said 'We've done a factory reset...but it's still doing it'

I also tried, on the advice of a sony mobile operator, a software repair using a USB...NUFFIN!  I'm amazed (and pretty disgusted) that on the Sony forum ON SONY'S OWN WEBSITE that not one comment has been made by the manufaturers/sellers of this.

Re: Screen goes black when making a call

!!! SOLUTION FOUND !!! :-D

Covering the left half hole on top of the screen just above the Sony print.
( and hence the proximity sensor ) Seems to do the trick!
You can cover half the hole with your finger during calls.
Or add a small piece of black tape.

As? the software for the proximity sensor in Lollopop 6 update
seems to operate 'in reverse functionality'. ( Sony. Please fix this.. ;-| )

Some managed just to clean the hole with blue window cleaner
and a cutton pen cut in half. But I had to cover it permanently in order
for the screen to function properly during calls again.

Hi JonathanFW,

 

I tried this method and also turned the proximity sensor off using the instructions in the Youtube video below but the screen still goes black.

1 - In the dialer enter *#*#7378423#*#* 2 - Go to Service test, then Proximity switch 3 - Move your hand above the left side of the Sony logo 4 - Click back and try to make a call

Re: Screen goes black when making a call

Hallo
I had same problem for little while
I fix it.the problem with my phone was that left top corner of screen had small gab (about 1 mm) from frame due glue malfunction or something.
I had to glue back the screen very tight and it help
Check for gap or try to press top of the phone during the call ( leave light sensor free)
