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.

Hi @xavinux

Please suggest some fix for this or share the link to rollback two of Sony xperia z3 compact updates for users who have this problem. Without back/home button, I can't move between applications and the navigation is complete mess. Every time I have to restart the phone to work on a new app it to return to home screen. This is such an annoying update. Waiting for your reply at the earliest.

@hue899
If you come across any work around to fix this issue please post the same. Thanks.

Any updates available for this issue.? Pls update. Or you suggest me to take my phone to service center?

Visited sony service center. It's a known issue it seems. Those who are having this issue please visit service center before its too late. Looks like there is a problem with screen panel.

Hi all. Now,I have problem about drop-down notification too. First i try reset my device result to data is loss and can't use drop-down notification yet. I try to change theme & icon from Line Launcher application result to use drop-down slide for home screen only but can use for other application or remain page. And version for my device is same @user105 Apprentice. Please help me for this case. Thank you ((;

@AliceBtBig: If you face this problem soon after you updated the software most likely it has to be the same issue as mentioned above.

Check with Sony service center if it's so. My Sony panel replacement was covered under warranty. Good luck.

Hi @AliceBtBig

Please, first run a backup of the device information as explained here. Then perform the system repair using PC Companion or Bridge for MAC. This will factory reset your phone and erase all data. You might need to charge your device for about 1-2 hours before so the device has at least 80% battery. Make sure the device is not connected to computer or laptop and turned off until you are prompted (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device). Start PC Companion -> Support zone -> Update my phone/tablet -> Blue Repair my phone/tablet -> follow instructions. When prompted connect your phone still switched off holding volume down or back button. The repair or reformat process will start. If you are using Windows 8/8.1 or a 64 bit operating system adjust settings for PC Companion and run in compatibility mode -> chose Windows 7 or XP. I´m at disposal for any question.
