Navigation bar doesn't respond

[Z3C_user1]

Hi, I have been using my xperia Z3 compact for 2 years. Suddenly, the navigation bar stopped responding. Home button doesn't work when I tap on it nor do the back button and the button for recent apps. I restarted the phone a few times but that didn't help. Please help me.

Using the Pc Companion repair didn't work but at least I wasted some time and lost my data and settings.

Try to install Microsoft launcher from Google play store, find gesture option, change to status bar, worked for me..

Go to settings. Select one handed operation. Click on the button to double tap the home button to get to navigation bar. The bar should be displayed as a list 😀

I installed the app Soft Keys 2. It puts another navigaton bar on the top. You have to resize it to a smaller size in order to have still access to the keyboard. My sony xa1 has unresponsive edges and navbar. That was the best solution
