Sony z3 compact xperia back and home button not working

[User105]

I am using z3 for almost a year and dint have any issues. Since last two updates i am facing two problems.

1. The drop down notification menu does not displays properly when slided over from top to bottom

2. Back and home button works once in a blue moon. Previously they were working great. Now i will have to try for more than 25 times to make that happen or restart the device.

Please let me know if this is a software issue caused by the latest software release or is there a way to bring back the old version of software. Eventually i need a working software and not this piece of ugly software quality.

Please respond when this issue will be resolved.

@Solardub, I keep seeing that guys swore over glove mode and some with apps like back button. I have been there, done that. Eventually the phone died anyway. My mileage was 22 months before the screen starts giving problem and goes downhill from there, completely unresponsive within 6 months. I see a pattern here which tells me that this is not an isolated incident. Bravo Sony, now I know that this has been a planned obselence anyway. I saw forum post somwhere that no software solution works. It is hardware problem.

Guys, i found a solution in a german Forum. 

Requires some knowledge though. 

Z3 compact into USB-Debugmode 

Telofone - Press and hold Build-Number again and again until you are in Developer Mode

-Connect via USB and MTP mode
-Download ADB tools on your desktop pc
- open adb tools console and type adb devices to check if the device is connected ( maybe you have to install a adb interface driver first
- type "adb shell wm overscan 0,0,0,30" 
-> done 

Original Text : 

 Z3 compact in den USB-Debugmodus bringen:

* unter Einstellungen - über das Telefon - "Build-Nummer" mehrmals gedrückt halten, bis "Sie sind Entwickler!" erscheint
* unter "Entwickleroptionen" das USB-Debugging aktivieren​

- Handy per USB verbinden und "MTP - Daten übertragen" als Übertragungsmodus wählen
- ADB-Tools downloaden (siehe Google) und die Zip-Datei entpacken
- im Explorer den Ordner öffnen, in dem sich die adb.exe befindet
- Rechtsklick mit gehaltener Shift-Taste in einen freien Bereich -> "Eingabeaufforderung hier öffnen"
- "adb devices" eingeben und prüfen, ob das Handy gefunden wird
- "adb shell wm overscan 0,0,0,30" eingeben
-> fertig!

Thanks @Mk2017!

That solved it for me. Z3 Compact here

@Mk2017 this is not a solution, but best workaround I have seen so far.
It basically move your nav bar a bit higher (so makes a little of the bottom screen unusable), but at least I can use my nav buttons normally, without any glove mode and such. Thanks.

Great !
I found my navigation buttons, for my part I limited the loss of pixels to 20 (put 0,0,0,20 instead of 0,0,0,30, make tests)
Tanks!

Super !

J'ai retrouvé mes boutons de navigation, pour ma part j'ai limité la perte de pixels à 20 ( mettre 0,0,0,20 au lieu de 0,0,0,30, faites des essais) 

Tanks !

I am experiencing the same issues with back and home buttons. 

Excuse me for not trawling through 43 pages on this topic but , if this is a hardware issue, can someone tell me why buttons work in glove mode but not in normal mode? It seems to me that if the screen is 'dead' in that area, surely glove mode should not work either?

Again, apologies if this has already been covered.

Have the same problem.

I think it started after updating the Android System webview.
Factory reset doesn't fix this.

Wish Sony provided an update about this issue.

Génial ça marche !

Great it's work

Some details to help :

Open a Command windows (windows-r then type "cmd")

Change to the directory vers adb.exe where uncompressed (type "cd PathToADB")

then type "adb shell wm overscan 0,0,0,30"
