Hello Sony Community
Right after performing the latest upgared both the phone and Contact apps stop by themselves with the annoying message: "Unfortunaately x has stopped".
Already tried the factory reset, eliminating google plus, changing the format to 24 hours and it doesnt work. All hanges were done independently.
Is there an option to perform a roll back of software if t was created by the latest upgrade? I dont mind going back with a more robust SW as log as the phone works.
Worst situation for me as I am traveling 
Please advise,
you can contact your Local support to see if they can inspect your phone, you could also repair the phone with XC
Alternatives on How to backup Xperias
Same issue here with E6653, even after a factory reset. It happens after updating my software to 32.2.A.0.224
I'm sorry to hear that 
Would it be possible for you to take a log file from your phone after the contacts app has crashed and send this to me?
To do this:
Settings > About phone > Build number, tap 7 times on the build number
Go back to Settings and select Developer options and turn on "USB debugging". Then tap "Logger buffer sizes" and set this to "4 M".
- Restart the phone and then open contacts. If it crashes:
Settings > Developer options, select "Take bug report". When the report is ready (may take a minute or so) you get a notification that you can tap and share to Google Drive. Please send me a link to this file in a private message.
Think I'm having the same issue.
Z5 Compact updated to 32.2.A.0.224 yesterday.
To reproduce:
Go to Phone -> click on the green circle with dots to bring up the keypad -> press any mumber - Unfortunately, Contacts has stopped
or
Contacts -> click on any contact - Unfortunately, Contacts has stopped
Same thing happens in safe mode.
I tried clearing the cache and data for the Contacts and Phone app, wiping the cache partition, nothing worked.
The only suggestion from phone support is to reinstall the OS using the phone xperia-companion which I'm not ready to do yet since that's the nuclear option.
Let me know if you want the crash report log file if that will help Sony debug the issue, seems like it's common.
Appear to have same issue. Last night installed android update and now if I want to enter a number to call it closes after the first character and when I click save on a new contact. The ONLY way I can now use the phone is if it is in the call history. Tried clearing cache and I do not have google +. If I factory reset wont it then tell me in a few days i need to update it again to this version that appears to be causing the problem??? Phone is Z5 premium dual sim.
